I've been getting a lot of questions lately about my Killacycle.com LiIon BMS, and about my homebrew DIY Surface Mount techniques. As you can see, I'm not a very good writer, so I thought I'd upload a draft of a contest entry I put together.

The below video clip is of my CNC Taig mill setup as a surface mount Pick and Place machine. It's slow, but it's more fun watching it do the work then it is to do it by hand! Notice how it picks up the parts in one orientation, and then rotates them to the correct destination orientation. It then "centers" the part in the "centering pit". Also notice the way-cool http://www.HighTechSystemsLLC.com Modular Work Holding System that holds the PCB down on the HighTechSystemsLLC.com tooling plate. It makes clamping the PCBs down a snap!
