Today I've found an old dead DVD-RW drive in my box with junk. I decided to test macro photo with my mobile phone cam (Samsung B7350, 3 Mpx) and a drive head lens. Just for lulz.

74HC595 breakout board
Recently I've bought a bunch of cheap 74HC595 shift register IC's. But SOIC case is not suitable for solderless breadboard. I didn't want to buy this IC's in a DIP case too, so I've made my own breakout board for them.
Single side PCB with 3 jumper wires on top side. Not so small as Adafruit's (for example), but easy to make with laser printer and iron. Supports daisy chain.

Tiny glue gun mod
Some time ago I've bought a really cheap and simple glue gun. Device works fine, but there was no power-on indication.
Today I decided to make tiny device update =)
