[Flávio Ribeiro] Snickers: Open Source HTTP API for Media Encoding

July 18th, 2016

At the beginning of this year we created a group on our video engineering team to deal with the ingesting, encoding, publishing and syndication of The New York Times videos. The main goal of the team was to build a pipeline that is vendor agnostic, cloud-based, efficient and elastic. We also wanted to build an easier workflow for video producers in the newsroom and third-party partners who distribute our videos. We named this team Media Factory.

After a few months of development, the pipeline is almost ready to be deployed to production. It consists of three different steps: Content Acquisition, Transcoding and Distribution. The content acquisition part is responsible for receiving ProRes/Raw videos, the transcoding API transforms the source files in playable videos by our supported browsers and devices and the distribution step sends the final videos to our CDN.

Probably the most important and complex part of the pipeline is the transcoding process. Instead of using heavy and expensive hardware for that we decided to create clients for different encoding services like Encoding.com, Elastic Transcoder and Elemental. This enabled us to decide which one to use based on a set of variables such as availability, speed, formats supported (HLS, webm, mp4, DASH, etc) and even cost.

While discussing the design of the pipeline and the integration with cloud services, we thought it would be useful (and FUN!) to implement another provider that would be just a tiny wrapper for FFmpeg or GStreamer. By using this tiny wrapper, we would have the freedom to deploy anywhere, implement new features (such as the generation of thumbnails) and perhaps, one day, be used to encode our lower priority jobs.

We have plans to write a blog post about the details of each step and how they work together on the Open Blog. We should work on that as soon as we have people at the company using the pipeline.

Time To Learn Some Go

After having a lot of fun on the journey to remove Flash from our player I got attracted by the chance to be part of this team. I was already willing to work with back-end services again and knowing that the company is adopting Go for API’s turned this opportunity into something even more attractive. Although I was participating on meetings and design decisions, I actually started working on the team in April.

I had never worked with Go before and after a few years plunged on dynamically typed languages I felt a bit of pain during the first steps working with it. The rest of the team was already fluent and I though I’d need something to exercise myself and keep up with the team’s pace.

Creating this dummy provider that is a wrapper for FFmpeg seemed like a good chance for me to evolve my Go skills. A month ago I started writting it, I called the project Snickers. I put this name because it’s my favorite chocolate and I was holding one when I created the GitHub repository.

To be honest, the title of this post doesn’t actually represent the current state of the project. Right now, it looks much more like a proof-of-concept/embryo project than anything else.

It supports the download of sources from HTTP and Amazon S3, encode them in H264/MP4 or VP8/WebM using a FFmpeg binding and uploads the results to Amazon S3. We still need a plethora of features to be able to actually call it a Media Encoding API, but one of the purposes of this post is to broadcast the idea and try to engage people to collaborate. Snickers already has contributors!

Next Steps

I have a bunch of ideas for this project. The next steps include building clients in JavaScript so people can use Snickers directly on the browser (with nice progress bars and stuff) as well as a client in Go, probably as part of the encoding-wrapper project. We also need to write some glue code for the Transcoding API so Snickers can be considered in the decision process of Media Factory pipeline. We use a lot of HLS at the company so HLS support is mandatory and probably the highest priority feature.

I’m also interested in working on the creation of a GStreamer driver for the encoding part so we can have benchmarks using different drivers. I saw that there’s already a Gstreamer binding for Go and it seems that the code is simpler than handling libav calls.

You can find some instructions on how to deploy and use the API as well as some examples. I also labeled a bunch of relatively easy issues in case you want to work on and be part of this project.

[Fabio M Costa] VACUUM PACKAGING – FOODSAVER COOKING UNDER VACUUM SEALER

July 14th, 2016

It’s been a while since I eye on cooking under vacuum at low temperature. It is a technique that is found in many recipes because it is perhaps the most cooking that respects the product and even improves its quality to some extent.

Last weekend I tasted my first meat cooked at low temperature in a restaurant. A piece of veal fillet of exceptionally tender, never eaten like this, cooked several hours at 55 ° C under vacuum in a water bath.
I hesitated, but it convinced me!!!

Some technical

Where to start?
There are two types of devices for evacuating the outer suction machines and chamber machines.

The machines bell are those that equip professionals because it allows a very high vacuum, setting liquids vacuum, the use of cheap plastic bags, but among the faults, for the particular, there is the very high price. And even if the price was not an obstacle such materials are imposing and heavy, they will not fall in a closet after use!!!

The machines external suction is against much less bulky, lighter and cheaper. In return they are less efficient, the vacuum is less extensive, and they should be frozen liquids and strong moist products before putting them under vacuum. It is also mandatory to use embossed bags more expensive than plain bags.
But overall, unless you make more than a dozen vacuumed daily, buying a family suction machine confine most of us and this type of material I choose.

The choice

In this market, there are all less than 30 € more than 200 € for certain professional boundary machines.
Looking on the internet, I came across demonstration videos of the FoodSaver brand, a brand that seems well known in the USA, obviously with a good reputation for quality and reliability.

Three models are from 85 € to 160 €. The differences lie in the possibility of manual adjustment of vacuum and particularly on the model Food Saver v4880 on which we can control the power vacuum. This model is cumbersome, but the roll of bags can stay inside, and it can be stored in the vertical. This is the model that I chose. Click here for the full foodsaver v4880 review.
I forgot to mention that the vacuum is not only for slow cooking purpose but also improving food preservation, especially when oneself frozen.
Often your frozen products make water which crystallizes on the surface, they dry, take not terrible and ultimately smells good to throw away. With the FoodSaver vacuum Announces Conservation 2 to 3 years for frozen houses.

For wet products such as fish, it is advisable to freeze the product quickly before putting it under vacuum to prevent the liquid from being sucked by the pump and destroy it forever. There is good security in the FoodSaver with a groove that holds the liquid and crumbs before they pass through the pump, but I do not amuse me to test the effectiveness of the device!!!

The bags

For bags, it is mandatory to use embossed bags that cost a bit more expensive than smooth bags.
The roller supplied as standard can already do some evacuated and then contrary to what one might believe it is cheaper to buy ready-made bags that roll, it’s almost 2x less!

First low-temperature cooking

I made my first test of low temperature cooking with a piece of pork tenderloin, evacuated, and then baked for 4 hours in a steam oven at 70 ° C. Since I did not yet control this type of cooking I assured the blow by sticking a probe in the heart of the net, through the plastic. The bag remained well sealed despite the hole, and I think that the rest as we do not touch the probe.
I pulled my bag from the oven when the temperature was at heart at 63 ° C at least 30 minutes. I did return the fillets to a hot pan with just olive oil net time to form a colored crust to taste through the Maillard reaction. And all comes fine!

Beautiful pinkish color and flexibility are suggesting exceptionally tender. In the mouth, it is a rediscovery of pork. Fondant, a pinch of salt simply is outstanding, after that it will be difficult to eat pork cooked this way differently !!!

The air fryer is a useful tool in the kitchen. It would be unfortunate if your cooking appliance would break by accident. If you want to use your conventional cooking appliance to the best of its abilities, then it would be a good idea to take care of it properly. Make sure that you follow these tips as it can help you use your air fryer for a longer duration.

1. Make sure that you read your manual before use.

As with any appliance or even gadget that you have, it is better to read the manual first before you use your air fryer. Since the manual that came with your product contains the list of guidelines to properly utilize your tool, then it is a good idea to read it before using your air fryer.

The safety manual is your bible when it comes to your air fryer. Aside from displaying warranties, it also has a list of the things that you should and should not do with your air fryer. If you read through the instruction booklet, then you are less likely to make mistakes that can cost the functionality of your air fryer.

2. Use your air fryer regularly.

If you buy an air fryer, try to make it one of the primary tools that you use whenever you prepare your dish. Make sure that you don’t leave your air fryer unused for a log time because some of its internal circuits might take damage.

It would be much better for you to use your air fryer when you cook. Leaving your air fryer to its box after an initial use would present several problems – from circuit breakages to minor electrocution. If you buy your new air fryer, you should use it when you cook your meal. While you don’t have to use it daily if you prefer not to, it is best for you and your air fryer if you use this appliance weekly to avoid disintegration.

3. Clean your air fryer with minimal water or liquid substances.

When you clean your air fryer, try to use minimal water when you do so. In fact, it would be better if you use no water when it is time for you to clean your air fryer. Because the air fryer is an electronic device, it doesn’t work well with a lot of water on it. There are several hazardous incidents that may incur if you choose to use water to clean your air fryer. From product combustion to electrocution, there are heavy results for using water as a cleaning device.

If you are wondering about what to use in cleaning your home appliance, then I advice you to use a cloth or a rag for cleaning purposes. Since the air fryer is easy to clean by itself, using the cloth would be enough to clean your cooking appliance.

[Fabio M Costa] THE STEPS FOR USING AN EMBROIDERY MACHINE

July 4th, 2016

Today we enter the heart of the matter because we will embroider a design with the computer embroidery machine! I chose a breathtaking free pattern made with four colors of thread (the steps that I will describe apparently remain the same regardless of the number of changes the pattern).

1st step: defining the location of the pattern on the fabric embroidery

This is a MANDATORY step. Be careful with the size of the pattern (observe proportions compared to the garment embroidered or object) and its location on the fabric.

Tip: If you can, print your design in actual size to visualize its location. Otherwise, please refer to the pattern dimensions of the tissue or to create you a very simple template paper.

I printed my motive, then placed the sheet under to assess its size and position.

Then only make a mark on the fabric (usually, we take as a reference the center of the pattern, but it can happen that one may need to take the edges of the pattern as a guide, when embroiders series models for example).

Step 2: placing the fabric in the embroidery frame

After scoring embroidery marks on the tissue, the “stuck” in the framework and that is where lies the thorny question, “Should I use a stabilizer material every time?”. In theory, professionals will tell you that yes, it’s better. Now I will give you my reflections on the subject.

The reinforcement does not seem necessary if:

– The fabric is thick and not likely to move in the frame (for example, upholstery fabric or denim spandex SANS);
– The reason is simple, without dense filling, and small (like embroidered monograms on my dragees bags);
– If you just want to test a reason: I do my testing on scraps of upholstery fabric (on the back if the material is printed), and I do not use reinforcement (no small savings! )

By cons, it is best to:

– The fabric is light: cotton for example;
– The structure is distorted: knitwear, jersey;
– You embroider sponge;
– You decorate delicate fabrics like organza or silk.

In these two latter cases, it is even necessary to place a water-soluble on the fabric. But I will talk next time these particular situations.

The fabric I chose was quite light and dense pattern, I stuck the water-soluble fabric reinforcement in my (with a little spritz of glue for embroidery there is no need to put too much), then j ‘I stuck my fabric and the stabilizer in the embroidery frame. To position it correctly in the frame, I used the plastic template provided. This grid allows you to place your fabric straight in the frame to check that the embroidery frame is correctly positioned and that the pattern itself is well understood in the embroidery field.

Tip: I deliberately placed the center of my most downright design possible on my part because the model is relatively small compared to my surroundings, so I can recover a larger piece of water-soluble surplus after embroidery (for reuse with smaller frames, for example, or for sewing buttonholes).

Once the fabric correctly in the frame is tightened the screw and pulling the sides of the fabric to remove any slack in the structure, it should not remain “beads” (remember to use the small key used unscrewing crowbars came with your machine to tighten the screws of the frame or even a screwdriver!). Be careful not to tighten either over, nor too soft fabric, the aim of the game is not able to make a tambourine !!

Step 3: The machine performs embroidery

It sets the framework of the machine, selects the pattern and adjusting the position of the plan about the benchmark which was drawn: by changing the position of the pattern; the frame moves, until the needle is correctly positioned above the mark:

If you have several changes of a son, put your spools in their “order of appearance” next to the machine, the color changes will be faster and be less likely to go wrong in the colors.

It sets up the can (with special yarn bobbin for embroidery), is slipped over the first color to be embroidered and you can start embroidering. It is held the line of embroidery at the beginning for a few points and then once the embroidery is started, it stops the machine to cut the excess of this thread (if you do not, it may be taken in embroidery and then it will be harder to cut).

When the embroidery of the first color is completed, the second coil is threaded and is repeated as before. This is done until the completion of the embroidery.

Step 4: Finishing

Once the embroidery, the frame of the machine is removed, loosen the screw of the frame, and the fabric is removed. We cut small son protruding on top of the embroidery, but not those below unless the back of the embroidery is visible (as a scarf for example). Reinforcing the excess is removed by cutting around the embroidery and taking care not to cut the son.

Tip: If you plan to stitch decorative stitches (as below) or a buttonhole near your cause, do not remove the reinforcement immediately, but cut it after doing your sewing because the decorative embroidery and buttonholes out better with reinforcements.

You then left to spend your fabric with water to dissolve the water-soluble (dissolves mine to 35 °).

And that’s a lovely embroidery done in less than 20 minutes!

 

[Fabio M Costa] BATTERY TESTERS AND STARTING AIDS – APPLY AND KEEP YOUR BATTERY IN TOP CONDITION!

June 24th, 2016

Your car will not start because of a dead battery? We will give you tips!

Has it already happened to you? You step out the door, walk to the car and press the central locking, and nothing happens? At first, you still think that your best car batteries has run out and do your good spirits open the car with the key. You get in the car and notice that the interior also has not been dropped. Will it not? You put the key in the ignition, turn him around and nothing happens! Battery empty! In most cases, this is because you unknowingly let something like the radio or lights.

It can also happen that you have to be the just battery is broken and replaced. This is particularly extreme (weather) conditions, such as a severe winter. There are also battery packs which gradually deflated and can not be recharged more maximum. This causes problems especially in diesel engines because they have peak current necessary to start at the first time. We try to give you helpful tips on how to avoid an empty battery and what to do if you still need to be fast at work.

Tip 1: Avoid an empty battery with a battery tester

Knowledge is power, and prevention is better than cure! With a battery tester can check the status of your battery, so you can intervene before it is too late. Today there are battery testers in all price ranges, from a few tens to hundreds of euros. What you need, you decide for yourself.

The cheaper versions often come in the form of cigarette lighter plug. These measure the battery voltage when the ignition is switched on, simple! The meter about 12.7 volts then your batteries full and you have no problems. Is the voltage below 12.5 volts then you have to worry. You’ll probably leave something like an interior light. Whether your battery is not charging more for 100% and needs to be replaced. Always make sure your engine is turned off once you do a reading. If the engine is turned on, the meter anyway a voltage of about 14 volts because the alternator charges the battery when running the motor.

With the more expensive battery testers can get a complete analysis (starting power, cold start current, alternator test, etc.) making your battery, but this is not profitable for private use. These testers are particularly interesting for companies because you can also check the truck’s battery.

Another way to ensure that you are faced with an empty battery is testing the acidity of your battery acid. This can be done easily with a battery tester. Watch out, because you’re dealing with corrosive acid.
Again, this works very directly. You turn one of the caps from the battery and plug the meter into the acid of the battery. Then squeeze the suction ball and the meter will tell you by color in what state is your battery. Red means charging directly, blue is half full and yellow in order.

Tip 2: Do you have a dead battery? Use jumper cables or a starting aid

It’s probably happened to you once; you want to drive to work, but the car will not start. Shit, a dead battery? What now? Well, there are two options:

  • You grab the jumper cables in your trunk and start your car using the car of the neighbor.
  • You use a starting aid (jump starter) to boost your battery.

The significant advantage of jumper cables is that they are relatively inexpensive. For two bucks you already have a good set of wires. The downside is that you always need an extra car to talk to get your battery. With a starting aid that is not necessary, so this also slightly more pricey. The big advantage is that you are not dependent on a 2nd car.

If you start a car using jumper cables

Set the 2nd car nearby and check on which side of the 2nd session of the battery. This i.v.m. the length of the jumper cables. Run the engine of the 2nd car and grab the red jump lead. Put the clamp of the red jumper cable to the + of the 2nd car then the + of your dead battery. If you can not find the plus on the battery, you can recognize a red mark on cables or batteries.

Now do the same now with the black jumper wire. First, set the clamp to the negative terminal of the 2nd car battery and then to the negative terminal on the dead battery. Note: this may cause a spark, try to do one good.
Wait a few minutes to start the dead battery. Start him and then let the engine run for a few moments to connect jumper cables.

Remove the clip of the red booster cable which is on the charged battery; then you get the red terminal of the battery. Repeat step 5, but for the black jumper wire. Now you can start the car again, but make sure you’re not slow to turn. Then you will do over again throughout the tune, and no one is waiting. It takes half an hour to an hour before you can start again independently of the battery. Do not forget this!

If you start a car with a starting aid/jump starter

A starting aid is also called a mobile battery. This just provides enough power to start your (almost empty) battery. The big advantage is that you do not need an extra car, and you do not depend on others. The connection operates in the same way as for jumper cables as we have described above. Note here also good that you put the clamps on the right poles. A starting aid often has a built-in compressor, an LED lamp, USB and a 12V socket. You can also inflate your tires, and you can see in the dark what you’re doing. With the USB connection, you can even charge your smartphone. Handy!

Where have you to be careful when buying jumper cables or a starting aid?

The capacity of a car battery depends on upon the size of the engine, and whether it is a diesel or petrol engine. The latter is of significant influence on the thickness of the jumper cables and the capacity of your starting aid. A diesel engine needs a lot more power than a gasoline engine. Namely, a diesel engine starts with a glow plug and an engine with a spark plug. A glow plug consists of small incandescent spirals, but these consume, like an electric heater, a lot of power. For a diesel engine, you can use a wire thickness of from 25 mm2, depending on the size of the engine and is therefore of your battery. Tip: check the car battery capacity and purchase on that basis starting cables.

For a start aid course applies the same. Again, it is the power to be supplied to initiate the car or truck. It is important that you not only pay attention to the thickness of the cables, but also on the capacity of the starting aid. The amps of starting aids range from 8 up to 1,500 amperes. Before purchasing a starting aid, first, check your battery, so you know which one to buy.

Your car will not start because of a dead battery? We will give you tips!

Has it already happened to you? You step out the door, walk to the car and press the central locking, and nothing happens? At first, you still think that your best car batteries has run out and do your good spirits open the car with the key. You get in the car and notice that the interior also has not been dropped. Will it not? You put the key in the ignition, turn him around and nothing happens! Battery empty! In most cases, this is because you unknowingly let something like the radio or lights.

It can also happen that you have to be the just battery is broken and replaced. This is particularly extreme (weather) conditions, such as a severe winter. There are also battery packs which gradually deflated and can not be recharged more maximum. This causes problems especially in diesel engines because they have peak current necessary to start at the first time. We try to give you helpful tips on how to avoid an empty battery and what to do if you still need to be fast at work.

Tip 1: Avoid an empty battery with a battery tester

Knowledge is power, and prevention is better than cure! With a battery tester can check the status of your battery, so you can intervene before it is too late. Today there are battery testers in all price ranges, from a few tens to hundreds of euros. What you need, you decide for yourself.

The cheaper versions often come in the form of cigarette lighter plug. These measure the battery voltage when the ignition is switched on, simple! The meter about 12.7 volts then your batteries full and you have no problems. Is the voltage below 12.5 volts then you have to worry. You’ll probably leave something like an interior light. Whether your battery is not charging more for 100% and needs to be replaced. Always make sure your engine is turned off once you do a reading. If the engine is turned on, the meter anyway a voltage of about 14 volts because the alternator charges the battery when running the motor.

With the more expensive battery testers can get a complete analysis (starting power, cold start current, alternator test, etc.) making your battery, but this is not profitable for private use. These testers are particularly interesting for companies because you can also check the truck’s battery.

Another way to ensure that you are faced with an empty battery is testing the acidity of your battery acid. This can be done easily with a battery tester. Watch out, because you’re dealing with corrosive acid.
Again, this works very directly. You turn one of the caps from the battery and plug the meter into the acid of the battery. Then squeeze the suction ball and the meter will tell you by color in what state is your battery. Red means charging directly, blue is half full and yellow in order.

Tip 2: Do you have a dead battery? Use jumper cables or a starting aid

It’s probably happened to you once; you want to drive to work, but the car will not start. Shit, a dead battery? What now? Well, there are two options:

  • You grab the jumper cables in your trunk and start your car using the car of the neighbor.
  • You use a starting aid (jump starter) to boost your battery.

The significant advantage of jumper cables is that they are relatively inexpensive. For two bucks you already have a good set of wires. The downside is that you always need an extra car to talk to get your battery. With a starting aid that is not necessary, so this also slightly more pricey. The big advantage is that you are not dependent on a 2nd car.

If you start a car using jumper cables

Set the 2nd car nearby and check on which side of the 2nd session of the battery. This i.v.m. the length of the jumper cables. Run the engine of the 2nd car and grab the red jump lead. Put the clamp of the red jumper cable to the + of the 2nd car then the + of your dead battery. If you can not find the plus on the battery, you can recognize a red mark on cables or batteries.

Now do the same now with the black jumper wire. First, set the clamp to the negative terminal of the 2nd car battery and then to the negative terminal on the dead battery. Note: this may cause a spark, try to do one good.
Wait a few minutes to start the dead battery. Start him and then let the engine run for a few moments to connect jumper cables.

Remove the clip of the red booster cable which is on the charged battery; then you get the red terminal of the battery. Repeat step 5, but for the black jumper wire. Now you can start the car again, but make sure you’re not slow to turn. Then you will do over again throughout the tune, and no one is waiting. It takes half an hour to an hour before you can start again independently of the battery. Do not forget this!

If you start a car with a starting aid/jump starter

A starting aid is also called a mobile battery. This just provides enough power to start your (almost empty) battery. The big advantage is that you do not need an extra car, and you do not depend on others. The connection operates in the same way as for jumper cables as we have described above. Note here also good that you put the clamps on the right poles. A starting aid often has a built-in compressor, an LED lamp, USB and a 12V socket. You can also inflate your tires, and you can see in the dark what you’re doing. With the USB connection, you can even charge your smartphone. Handy!

Where have you to be careful when buying jumper cables or a starting aid?

[Fabio M Costa] LAWN TRACTORS, MOWING ROBOT AND HOW TO USE

June 13th, 2016

Lawn tractors

Mowing driving! Make a lane of your garden. A tractor is mowing large surfaces you play. It sit, drives off, and send the best. You have heaps of fun while mowing. There are also best self propelled lawn mower electric start

From where it pays to purchase a lawn tractor?

Of course, there are crazy it looks like you’re sitting on your mower mowing your grass. However, you need not be a landowner to purchase such a machine garden worthwhile. Lawn tractors are already useful on surfaces from 600 m2 by their maneuverability.

The differences between lawn tractors and riding mowers: When a rider sits the driver above the engine, with a garden tractor is the drive unit before him.

The advantage of tractors is that they can be used for all kinds of work. They are not only suitable for cutting grass. There may also be devices such as snow blades, brooms, sprinkle trailers and become much more attached to.

The decisive factor is, of course, the price; mowers are a lot cheaper. Lawn tractors are smaller and less powerful than garden tractors.

Significant parts of the machine

Discharge to the rear or side

Garden tractors with ejection to the rear throw the mown grass without detours directly over the rear axle into the receptacle. This may be mowed high and wet grass. A Rider discharge side is suitable if you do not want to collect the clippings.

Transmissions

  • Trans-Matic transmission: a trans-Matic transmission can continuously switch. With the brake pedal can slow down the mower and drive off again without having to switch.
  • Hydrostatic transmission: the speed is in this drive adjustable without or switch.
  • Automatic transmission: the speed control and direction are governed exclusively by the accelerator. There does not need to be changed.

Mowing Robot

Do you know that? It is the weekend. You have anywhere fancy, except for mowing grass. Endlessly back and forth accompanied by the monotonous hum of your lawn mower. Then you once again stumbling over the cable from your electric lawn mower, or tank needs to be refilled, or the container for the cut grass is packed – always just before you are ready. Enough! Make your life easier anyway with mowing robots!

Advantages of a mowing robot

  • Power saving: never push more heavy lawn mower for you. Especially for older people is a significant relief.
  • Time saving: the mowing time is now free time. Yippie! Also, the garden machine takes removing clippings from here. All models have an integrated mulching.
  • Childishly easy: the operation is simple. Beacon lawn surface to be processed with the boundary wire and feed it into the machine. To work! Also, can be stored in some models week programs.
  • Environmentally friendly: no gas, no oil, no exhaust.
  • Silent: lawn mowing robot operates virtually silently.
  • Quality work: the machine can be optimally adjusted to your garden and thereby ensures a high quality of cut.
  • The result: a beautiful, uniform lawn.
  • Safe: the device is equipped with many safety equipment. The lift sensor will stop the mower when it is lifted, and a wire sensor stops the engine when he gets behind the boundary wire. The bumper sensor also takes him away from fixed objects.
  • Does not require much maintenance: mowing robot is suitable for all types of lawns and doing its job in any weather. Also, obstacles and ramps for most models no problem.
  • Such machines are also great for people with allergies.

TIPS FOR USING THE MOWER WITH ENGINES 4 STROKE

Gas

No need to use Premium gasoline. In the case where not get can be utilized without drawbacks. It is also recommended not to leave fuel in the tank for more than 15 days.

Type of oil: SAE 20W-50 or 15W-40 recognized brand (we recommend using oil Maruyama)

Oil quantity: You can vary engine models, but almost all have a pan 535c.c. (Not to exceed the level, could damage the motor). It is recommended to put a little oil and go with the rod controlling not to put more oil.

Oil change: It is important to remember that usually come without oil engines so before putting the equipment in place should be reviewed and put oil if necessary. Then, changes are produced according to the following scheme:

First oil changes at 5 hours of use

Subsequent changes:
– If we use mineral oil between 25 and 50hs of use
– If we use synthetic oil between 100 and 150hs of use

With the change of oil should be modified the fuel filter if the mower has one.

Air filter

It is important always to keep clean the air filter, so ALWAYS recommend cleaning after mowing. There are two types of air filter:

– Foam filter: Clean with water and detergent. Once you clean it will drop a few drops of engine oil and spreads to permeate the entire screen.
– Filter paper: In this case the dry filter is cleaned so a compressor is used for cleaning. Always the compressor at least 15 cm to avoid damaging the screen and always in the direction “inside out.”

Lawn mowers with 4-stroke engines must work ALWAYS horizontally. The maximum allowed inclination is 15 degrees. Do not be fooled by sellers who do not know what they sell. NEVER use the mower more than 15 ° inclination. (NO ENGINE PROPERLY LUBRICATES)

[Fabio M Costa] INFORMATION AND ADVICE ON MEMORY FOAM MATTRESSES

June 13th, 2016

Memory foam mattresses are unique. Why is memory foam so unique you might ask? Good question! A good question deserves a good answer! We lay it out for you. In a few minutes, you can read more about unique features and particular advantages of memory foam mattresses. Buying a memory foam mattress can not just do. Choosing the right memory foam mattress is quite a challenge. We will help you with the good information and tips! View memory foam mattress topper reviews

The properties associated with a memory foam mattress:

  • Very comfortable
  • Excellent adaptability
  • Healthy weight
  • Pressure-lowering effect (good for the muscles and joints)
  • Very good insulation
  • Resilient foam
  • Long lifespan

HOW IS THE NAME “memory foam” GENESIS?

In the 70 was developed by NASA memory foam. At the launch of the space shuttle is a huge power gear free (G-forces). To cope better with these forces and to distribute the body was developed memory foam. The memory foam was never actually used in space shuttles.

Memory foam mattresses have many names: NASA foam mattress, Visco elastic foam mattress, foam mattress comfort, anti-decubitus mattress, medical foam mattress, lazy foam mattress and memory foam mattress. All names fall within the concept mattress.

HOW IS a memory foam mattress MADE?

Memory foam is a unique material. Memory foam is made from polyurethane foam as polyether and cold foam. The difference between the types of foam can be found in the cell structure. Memory foam has empty cells that are air-permeable. Thus, the air will not be pressed together as the cells are pressed together. The result is that memory foam reacts delayed. Pressing the memory foam mattress takes more energy and bounce back to its original state is slower than other mattresses.

Memory foam mattresses consist almost never 100% from only memory foam. The top layer of memory foam mattress is made of memory foam. The nucleus where the memory foam top layer is attached to must be supportive and resilient. The following combinations are possible:

  • Cold foam core with memory foam top layer
  • Pocket Suspension core with memory foam top layer
  • Polyurethane foam core with memory foam top layer

CAST or foamed memory foam?

Memory foam can make in two ways: Casting and foaming. What difference does it will make you think? There are great differences in quality among molded memory foam and memory foam. Molded memory foam is of lesser quality. The biggest difference is the price. Molded memory foam is cheap because the production process is much shorter than in foams. Foamed memory foam is breathable and wicks moisture and heat thoroughly. How to recognize the different types of memory foam? Molded memory foam feels rubbery, and foam memory foam feels like a sponge.

HUMIDITY AND AIR REGULATORY PROPERTIES

How good a memory foam mattress can deal with moisture and body heat is dependent on the cell structure. Memory foam mattresses are made in two different types:

1. Memory foam with open cells
2. Memory foam with closed cell structure

Memory foam with open-cell structure has the best moisture and air ventilating properties. The combination of pocket sprung with memory foam gives the best ventilating effect. The memory foam feels cool to the touch and has good moisture management. A memory foam mattress with pocket springs core is ideal for sleepers who easily hot or sweat a lot.

OPEN CELL STRUCTURE OF CLOSED CELL STRUCTURE?

Memory foam has an open or closed cell structure. The production of particular memory foam has an open or closed cell structure. The making of memory foam with an open cell structure lasts longer and therefore more expensive in price. Memory foam of high quality has an open cell structure. Cheaper memory foam mattresses often have a closed cell structure. The significant advantage of the open cell structure with memory foam mattresses is that wick moisture and drain well. The memory foam mattress will feel cool and fresh. Memory foam mattresses with an open cell structure suitable for sleepers who have difficult with a clammy feeling during sleep.

WHAT DENSITY?

Density memory foam can vary widely. Density is expressed in kilograms per cubic meter. The values start at 40 kg per m3 run up to 85 kg per m3. The density tells you how close the cells tightly together per m3. The higher the values, the closer the cells are packed together. The density in memory foam says something about the weight per m3 and the density of the cell structure.

In cold foam and polyether foam is a higher SG or HR values well. With memory foam works differently. The more kilos, the more mass. The cells are smaller, thus increasing the density. The smaller the cells despite takes more breathability from memory foam. It has the effect that it is hot, less moisture away and slow-moving. Says something about the density, the hardness of memory foam? It says nothing about how soft or hard is a memory foam mattress.

What can you keep best if you buy a memory foam mattress? It is important to find a good balance between the cell density and the ventilation capacity of memory foam. The values that begin with the best memory foam from 50 kg per m3 to 65 kg per m3.
