Successful 220v Coil
Posted: Thu Jul 17, 2014 7:33 am
So after being held in New Zealand customs for 10 days I finally received my kit yesterday. 15 Hours later (and an unhealthy amount of caffeine later) I now have a fully working OneTesla coil. I have to say this coil is amazing. Ran into a couple of issues though much like most people who've built one of these. I'm assuming a couple of the pads have oxidised which made it very difficult to solder to. Nothing a little persistence and acetone couldn't fix.
My biggest worry was whether or not the secondary would be in tune. I measured 250 ohms on the secondary and as such I went with a 6 turn primary. Would anyone recommend changing this? I haven't blown an IGBT (yet...) or fuse all the while taking it up to around 60-75% power.
Any suggestions for tuning? I unfortunately do not have access to an oscilloscope or signal generator, but I have a couple of engineering mates who do who wouldn't mind helping me out. In the time being, is there anything I can do to try and 'tune' it?
Here's a fixed power run of my coil as well as a midi-run
