Hey, I made an autorouter plugin for KiCad. It also made the most complex PCB you'll ever see:

I need to up my follower count so here's a game boy I bought in Japan for $20.
I was going to ask electronics twitter about this but I realized we all left, BUT ANYWAY does anyone have any pointers/platform rigs for a stitching setup with an AmScope?

After everything is put back together we can put the shells on and test it in the Powerbook. There's a tool called 'Battery Reconditioner' that will give you the serial number and verify everything is connected correctly.

After that, it's just a tiny bit of JB Weld around the shell. One side at a time, clamped in a vise. This part will take about a day, but after that I've got a brand-new battery.

Inside the duo are the cells and a few electric components.

The transistor-looking thing is a DS2401 - basically a serial number chip. It stores a unique ID number that can be read over a one-wire interface.

The longboi is a KLIXON 6MM81AA-04, a temperature sensor.

There's an unidentified component wrapped in heatshrink, and a 250A fuse (for real?!) in line with the connection between the 'innermost' batteries.

The battery corrosion can be taken care of with a fiberglass pen and fine steel wool. It'll work now, but take note of the corrosion I can't fix.

I bought a Powerbook Duo 280c from 1994 at a flea market last weekend. It works but the battery is long dead. This is a thread about rebuilding old laptop batteries.

First up, the battery itself. It's 10 4/5A NiMH cells. I don't know about the stock cells, but the replacement cells have 2000mAH each.

Anyway, I put the code for the 'Nedry' application up on Github:

There is a problem with the text encoding, because CR/LF is completely different between unix, windows, and mac. Yeah, have fun with that. But anyway here's the program running:

GitHub - bbenchoff/Nedry: Remember Jurassic Park? Remember the, "Ah Ah Ah! You didn't say the magic word!" animation that plays when Samuel L. Jackson tries to undo Newman's hacking? It's that. It's just a small little program that plays that animation over and over.
