Has anybody tried using electric double layer capacitors for the filter capacitor in a power supply?
I found I can get a hold of ten 4.7 F, 2.3 V low resistance super caps for around $30. I figured I would try building a +-10 V power supply with these babys. If I put five of them in series for each rail, it would be an effective capacitance or around 1 F.
I got this idea searching through the old messages. Some guy built a power supply using many 1000 uF capacitors in parallel to achieve something like 50,000 uF. It looked like he had a hundred capacitors in there.
