Something like this one.

Re: DIY spot-welder, FET-switched, processor-timed adj. puls

Has anyone used a Lipo based car jump starter battery as a power source? I know that they rate them as having 550A(!) peak current capability, however, it doesn't look nearly heavy duty enough. It's certainly more appealing than having a huge lead-acid battery sitting around. Thoughts? I'm thinking ...

Price drop to $6 shipped! All you need are the parts and some skill with a soldering iron to complete this kit. It doesn't get any cheaper than this.

Re: Compact Field Oriented Controller, ASI + Grin, limited r

I strongly recommend pulling a PR Utility XML 'out-of-box' file from your virgin unit as delivered before you tinker/autotune/etc so that you can restore the baseline settings if matters go awry. Can someone post that "out-of-box" XML file anyone is able? It would be very helpful, just in case... 8)
