Hi everyone, I have a little project I've been working on and I could use some help as far as the electrical aspects of it.
The idea is electrolytic rust removal, and the basic setup is this: A bin of water/washing soda with a rusty object submerged inside. The negative lead of a battery charger is attached to the object and the positive lead is attached to a piece of iron, in this case a rebar rod, which is also submerged in the water. This supposedly will de-rust the object without harming the unrusted metal.
One little problem, I don't have a battery charger. (Before I continue, please don't just tell me to buy a charger, I'm broke and want to try this anyway
Doing a little research, this is the plan I have come up with for a power supply:
Convert the standard wall outlet AC to DC using a bridge rectifier. I have four three-amp, 300V silicon diodes to make it with.
I also considered using a single diode to cause a sort of half-wave rectification, creating a pulsing effect to aid in rust removal; does this idea have any merit?
Now, I don't know what kind of current I want for this project. Should I try to salvage a transformer to lower the voltage going in to the rectifier?
I also heard that I could put a simple light bulb in the circuit, in between the diode(s) and one of the wall outlet plugs. This would supposedly act as a current limiter.
How does this plan sound?
