trying to build a cheaper version of something like:
**broken link removed**
In simple terms what device do I need to provide a variable dc current at around 1-3mA. The current must be continous given a changing resistance in the circuit.
Should I be looking at MASTECH HY1803D or simular perhaps smaller power supply?
