Hi Wolf,

Yes i tried to buy one from WIMA so i sent them a request. It was a 14V / 420 F / 900A type (SCMCA3B420MC00MV00 at I intended to switch it in parallel to my old battery in my car since i was nerved to replace it each few years. Also i just wanted to play with it. But the price, even including a discount of 30% for the university was very close to 1000 EUR!
But its quite a fascinating technic and i hope they will become cheeper in the next few years. That is the perfect energy storage! Leight weight, low volume, low internal resistance, lifetime 500,000 charge/discharges. Also interesting for the HF friends to drive a PA when beeing /p or /m for calling the own callsign in a pile up, taking 5 kA current consumption :-)

73, Stefan

Hi Stefan,

Yes, 3000 Faraday sounds reasonable. But the price may not.
Guess this is the type of capacitor used in 'batteries' to start large Diesel engines in trains (no kidding).

Hello Markus and group,

I will certainly look out for the signal. Only have to modify the soundcard's input coupling capacitor a tiny bit, guess I must connect a second capacitor in parallel. But sure there is something suitable in the junk-box.
If not, try one of these:
