I have built a bunch of stuff recently without updating.
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.
