Starting construction of H-bridge module.

I got the components from ELFA and Lawicel a few days ago. The first step was to set up the LM2574-based step-down converter, supposed to deliver a stable 12V supply to the HIP4081, on a breadboard. The schottky diode which is part of the circuit had pins so thick, I had to sandpaper them down to be able to push them into the breadboard holes... :)

I had no batteries at hand that could deliver the 24V I plan to use for the finished Segway clone construction, so I had to borrow a battery from my lawn trimmer, providing 21V. The circuit proved to work fine, at least on a quick minimal load test.
