Various cheap LCD panels can be repurposed using a $10-20 driver from Ali or eBay.
When a Thinkad is disassembled, there are like 20—40 fragile pins on the connector. I always just assumed it was custom and proprietary. Although it probably would not make sense for IBM to be in the LCD business, so I guess the pins must be standard (probably not the connector though). From there, can I trust the wire colors?
I ask because sometimes I find a destroyed laptop like a keyboard and base busted in half, where the LCD could be salvagable.
The most recent trashed laptop turns out to be purely the display, which was torn off, scratched up, and hanging by a wire. The power connector was smashed. But I got a Thinkpad docking station which supported an external display and a new power input, and it works just fine. It is now the fastest “desktop” in my house.
Precise (but weak) stepper assembly from old CD/DVD drives.
I had to look into how that’s useful. Apparently printers, engravers, and laser cutters are made with them. Requires a lot of ambition but if I really need one of those things and I hate what is in the enshitified marketplace, it might be interesting. I imagine the difficulty is in all the other components needed for those things.
Some old keyboards (especially programmable ones) have a DIP chip, if you are into building keyboards.
I did not know that was a thing. I have lots of spare keyboards and thought of using the linux app keyb to map chars like ½, “, ”, etc. to it. Thanks for the suggestion, b/c I think my plan of having two keyboards in front of me is a bit wasteful of desk space.
