Live on #DayGlowShow this Thursday: Arduino Alvik #CompanionBot hacking with @ishotjr ! I'll share a new tutorial on designing 3D-printed parts for this little bot, and David's got some #MicroPython code to crunch. Plus, updates on our other #hardware projects & upcoming events. Can't wait 🛠️ ✨

First semi-successful attempt at deprocessing by lapping. The outcome is extremely uneven, with metal2 remains showing over metal1, and a larger corner area being ground down to substrate.

Despite that, it may be possible to recover around half the bits visible in the ROM block. If done more conservatively and with multiple intermediate steps, full recovery can be performed.

I don't know what this device is other than sort of a doorknob; the C cells expired in 2013. What is up with C17? It's only connected on one side maybe.

So this is a weird one... I am working on a device that has two different things, and one needs 4.5v and one needs 1.5v.

Is there any reason I could not just solder a wire in place to just get power from one cell and also use the existing wire to provide 4.5v elsewhere?

I know this isn't the best way to do it, but it's a quick hack to make something work... I can't find an issue with it under that condition. Can you?

Today in semiconductor vendors having slightly too much fun packaging their silicon, AMD/Xilinx names a package "VSVA1365" that does not, in fact, have 1365 balls. At least they helpfully include a note in the datasheet 🙃

building and experimenting with a mock Peak Current Mode Controller similar to the ones found in buck converters, with just an op-amp and SR latch!

This is such a fun exercise, and lets you get hands on with PCMC type control at a more human timescale

Any simple suggestions on replacing C1 in this circuit?

What value capacitor(?) it is? Or likely to be?

C1 selected as possible fault on basis of possible magic smoke residues.

Board is from an artificial Christmas tree with optic fibre tipps in the foliage.

The green LEDs will now only flash for <0.5 seconds very very infrequently.

I have a multimeter and a soldering iron.

Suggestions for hashtags?

I successfully replaced the USB-C port on my Thinkpad without breaking anything, and think I levelled up a bit in soldering.
