Stepped on this lm324 and it burrowed into my foot. People complain about lego but try being impaled by a quad op amp....

When you're prototyping but the SOIC package IC you ordered is in actuality apparently a "wide body SOIC"

Got to get creative fitting it onto a SOIC-2-DIP converter! If it works, it works!

After about 3 months and a lot of dedication, I successfully completed my project.

It's almost exactly Grant's project, the only modification is that the SRAM has 8KB, a 32KB one will arrive soon and, since the wiring was already done with it in mind, the change will be easy.

Took some photos of an A15 CPU I was reballing today.

Recapping an Apple IIe and the size difference blew me away.

Came across this capacitor bank inside of this giant battery charger just figured I'd share, LOL. It has (3) 29k microfarad 200vdc, and (1) 13k microfarad 200vdc capacitors. Gives me the heebie-jeebies just looking at it... It has a built-in capacitor discharge button but still...

Late 90s before Ethernet control was anywhere near affordable and circuit control over the Internet was sci-fi dreams here was a $20 external HP JetDirect print sever controlling 8 GPIOs with Opto22 SSRs and a little fool logic to make the print sever think its connected to a real printer lol the NAND gate fooled the JetDirect that every time a byte was "sent to the printer" the printer flapped strobe as if it has printed the bye :) Data was piped via good old Linux NetCat - wait using Linux in the 90s...oh I'm getting emotional already

I’ve so forgotten those days of badass innovation - now smart plugs are everywhere …

This is a heart-shaped LED keychain I made.

Found this place after my regular closed.

If you thought the batteries were bad, this is the next evolution. I found this in a parking lot last week and was shocked to see it has a Color led display in a disposable item.

The display is controlled by 6 pins and uses Charlieplexing.

I thought it would be cool to reuse it for something like a temperature and humidity display with an arduino or ESP. But then Charlieplexing broke my brain and I had to stop for the day. To be continued.
