DT555 - Discrete Component 555 timer
This is a 100x65mm 555 timer heavily based on Evil Mad Scientist's Three Fives, almost identical. Buy theirs if you can.
All Three Fives specs should apply. Works between 4V to 15V.
Build instructions:
- Solder the brass nuts to the pads on the back side of the board. Use flux and a high power iron, or a heated plate, or a heat gun or a reflow oven.
- Solder the remaining components according their position. Every component value is labeled in the board.
- Install the 3D printed legs using the M3 bolts and nuts.
- Install the knobs with the M4 bolts.
