No need for an engineer’s degree!

This video from Bill Hammack explains it all in details.

Bravo à Philippe L.

Today, I was stopped by the sheer simplicity of this documentary film about a man who is the last piano repair parts reseller in Paris. A moment out of time.

La Mer de Pianos from Films & Things on Vimeo.

Here is how they made books in this long-gone era:

It ends with 5 minutes of cooling down for the brakes. If you want to see why and to have a better detailed view of it, look into it on a similar Airbus A380 brake test.

This white paper explores the aspect of reliability for this relatively new and specifically difficult soldering technology used in the manufacturing of boards of electronic components soldered according to the newest regulations requiring not to use any lead (even in soldering where it has long been the basis for solder paste because of its low fusion temperature).

Who thought that industry could be so densely colored?

• piston going down to suck gas and air in
• piston going up to compress the mixture
• piston going down pushed by the explosion
• piston going up to push burnt gas out of the cylinder

Let’s admire the actual operation filmed at ultra-high speed from inside the cylinder:

The International Space Station is the product of a complex assembly process out of elements brought upt here by rockets and the space shuttle. Here is a video animation from USA today showing the sequence of events in this build-up.

Everything changes as I found some freely available information available on the Internet. For example, AMD-ATI (designer and manufacturer or graphics cards for personal computers) published a small presentation video.

You can’t see much, it’s too short? Here come detailled videos from the Institute for Interconnecting and Packaging Electronic Circuits (IPC): IPC Training/Certification Videos. You will find there videos detailling all the stages of manufacturing and nearly all the significant technologies included in the manufacturing of electronic boards.

Most of them are available on YouTube and Google Video.

For those who went through all these steps and are still willing to learn, I also have a very intersting and much more technical presentation on a parallel issue and technology item: lead-free soldering. As a matter of fact, for years, the electronic industry has used a large quantity of lead (a cheap metal very attractive because it can become luidi at a relatively low temperature). but with the disappearance of a lot of the other sources of lead in our environment (lead poisonning (also known as saturnism, plumbism, Devon colic, or painter’s colic) is a medical condition caused by increased levels of the metal lead in the blood leading to neurological damage) electronic waste was adopting a bad sheep reputation. We are currently in the center of an intense transition to safer technologies. But it’s a whole industry which has to adopt completly new techniques and abandon very solid body of evidence and state of the art knowledge to learn uing “lead-free soldering”.

If you are ready for 30 minutes of concentration and listening, here is a video conference about this issue and a specific part of it: Electronics engineers like me will learn a lot about reliability of lead-free soldering.

Note: I said globe, not blog…

But here come some more, a lot more, fun with cars, trucks, excavators and other big chunks of mechanics.

Starting with a 15-ton Caterpillar playing along.

But should the Caterpillar stay on the ground? No, and this is what Dark Roasted Blend shows us:

But unloading an excavator seems much easier than unloading a car from a truck:

This means that you must be ready to repair your new car in all conditions. And some people really mean it. Here is the story of this rally race team. They had their car stopped by a broken throttle cable. So, in this case, what would you do? Abandon the race? Not these guys. One of them steps under the hood (!) and will handle the throttle from there to the end of the race.

So, this is the crisis, you are not ready to these extreme measures and you still need to buy a car, I advise all of us to chase a really carbon-emission-free truck (from a well-known battery provider):
