Although I am capable of building a project from a circuit diagram, I have not got the skill or education to design anything more than simplistic circuits, so I am here to ask for assistance from those with the education & skills.
My project is to build a circuit that will result in a constant output current of 3.8ma supply to a varying resistive load. I have a 36 volt dc power supply unit (from an old printer) as the power source.
The resistive load consists of two electrodes in an electrolyte which begins as Distilled Water, so very high resistance, which over time will reduce resistance as ions and particles increase in the electrolyte, but I want to maintain 3.8ma (well, as near as possible anyway) as the resistance of the load drops. This is vital to ensure the correct particle size and ratio of particles to ions in the solution. (Colloidal Silver)
Any help in this regard will be greatly appreciated.
