Re: Ion Sensing ideas and circuit designs
Would a boost converter be any simpler to make?

Re: Ion Sensing ideas and circuit designs
So does anyone have schematics for a 12V to 300VDC converter lying around?

Re: Ion Sensing ideas and circuit designs
Reading out the ion current isn't rocket science, but it does require a voltage in the region of 300V (I've seen 180V as well). This has been a showstopper for me so far. I've seen some designs which eliminate the 300V power supply by charging a capacitor to 300V with the 30kV (or so) spark and then...

Re: Ion sensing and peak pressure position estimation
Has there been any progression on this? I'd like to have a go at building the ion sensing circuit outlined in http://vvnet.fi/ville/ion/DIY-Ion-Sensing-2.pdf . However, I'm not entirely proficient when it comes to electronics (I'm a programmer), esp. the HV supply is a little out of my league. While...
