I built a battery charger last night using a soldering iron and $30 worth of parts from ebay. It connects four electric field sensors in series and then incorporates a balance board so that each lithium ion battery gets the same amount of juice. Pretty simply complicated if you think about it. I'm telling you this story because it looks like it came from China, and well it did - mostly, but my point is it still looks like it came from China. After all that cutting and hacking and soldering that is so often necessary for a proprietary space-y instrument, it still has that wonderful OEM finish to it. You'd never even notice it was modified and that's something I take great pride in. Making hardware for space missions that looks like you could pick it up at your local Walmart. That's an accomplishment. I wish I had my camera...
