Description
This PCB layout is a circuit for an analog/digital converter with a resolution of 1 mV (0.001 V). There's room for three 7 segment displays. The display can be used at 4 or 96 Hz.
Now, where's the ghetto part? Well, as you see on the picture you have to solder a transistor in a very unusual position because four(!) circuit paths have been placed between its pins.
There is also an error in the layout because the potentiometer is connected to Vcc+ but it belongs to GND!
Needed parts for the A/D converter
€ 1 PCB matching the layout
€ 3 7 segment displays with common cathode
€ 1 potentiometer
€ a few more parts because AdBa forgot to send us the part list

 | Just solder all the parts on the PCB according to the plan, that's it. |
