The heating element is just coiled nichrome wire, I've driven it with a weaker power supply to get hot enough for what I need, from what I have read you can keep increasing the current and it will just increase the max temperature. Any way to limit the current to it from this power supply to keep it at 6V for the arduino?
I measured the amps on the supply without it hooked up to anything, just the multimeter on the inner and outer leads.
