I have built a bunch of stuff recently without updating.

the first is a small breakout for a SPDT switch:

the next is a breakout for screw terminals so i can use anything with wires:

such as this switch:

next are two bargraphs soldered onto 74hc595 ic’s.  Both work, but on the first the order was not right for the leds, so I built another.  The led’s don’t have thier own resistors, but it works.  I was able to do this because I bought 10 of these chips for $3 on eBay.  The displays would have been under a buck to buy.  Last but not least, I have built another person:

his head, transistor, and diode are from disposable cameras.  The chip cost ten cents, and the perfboard is just a scrap.
