Whoa, two videos! Great to see you again. Any updates on the buried Raspberry Pi?

That battery contact is quite the design failure. Right where it comes out of the plastic (the "natural" bending line) the metal has the least width. And then it has a large tab with a big wire soldered to it, with neither the tab not the wire being properly supported. All that in a tool that's one of the worst when it comes to vibrations.

Bonus at the end :-)

Great video but so blurry! Just set a further focus =D

two videos in a week!!!!!!

Can't wait to see the silicon. AvE will need to take notes.

Always appreciate your vids :)

I'd say that terminal failed due to vibration cheaping out and soldering that thick wire directly to the terminal (instead of using a connector which would have allowed some movement) and not isolating the battery connector from the case with a rubber surround.

Looks like spot welded, but yeah connector would probably have been better, or epoxy around the connection.

I am a little surprised it is a DSP and not a more traditional microcontroller. I figure they must either use DSPs in something else and thus buy in bulk, or they really need the features/speed of a DSP

The real fault isn't the broken connection. It could still be used if the disassembly was not so destructive.

Is it next week yet?

Tear down the gear box too =D

@AvE .... you have competition

A lot of those tools also have DRM on them, and need to be activated by the store POS before they will work, as the POS uses NFC to communicate to the tool, that it has been sold, and thus can activate and be used.

What a load of BS. I had to buy a new motor for my Dewalt brushless drill because one of the coils had overheated and killed the electronics. It works perfectly again now. DRM, my ass.

@@simontay4851 You had to buy a new motor because the electronics died? Wouldn't you have to replace multiple parts?

​@jaro6985 a lot of power tools have the stator and electronics as one part because the wires need to be soldered and it's too much risk to rely on repair techs to do that. Very annoying as a stator or electronics failure means you have to replace both, and the part cost is often 70% of the price of a new tool

Which brand did you see doing that?
