The PCB board is about 83mm times 153mm and it is 1,6mm thick. | The PCB board is about 83mm times 153mm and it is 1,6mm thick. | ||
Before actually finishing the board, I had to get new capacitors because the ones I bought before did not have the right capacity. | Before actually finishing the board, I had to get new capacitors because the ones I bought before did not have the right capacity. | ||
I had to improvise a bit and the end result looks clunky, since the capacitors a quite big. They lie above the resistors R1 and R4 but because of the plastic at the bottom of the parts they do not interfere with the resistors. It functions how I wanted it to and I am happy with that. | I had to improvise a bit and the end result looks clunky, since the capacitors a quite big. They lie above and overlap with the resistors "R1" and "R4" but because of the plastic at the bottom of the parts they do not interfere with the resistors. | ||
I had some spare resistors left and I experimented with them. I soldered two on top of the resistors "R2" and "R3", that were already mounted on the board, so that they are connected in parallel to each other. By doing this I increased the blinking speed of the LEDs. | |||

When I was finished with the soldering process, I clipped of the pin from the battery holder that was sticking out from the backside of the PCB. But only the top one. The one pin below that I bend to make it look like a door handle. | When I was finished with the soldering process, I clipped of the pin from the battery holder that was sticking out from the backside of the PCB.
