I haven't tested the new DC driver because of money. There were unexpected expenses in Kenya with our daughter at her new high school. The drivers are identical except that the AC driver goes from -8v up to 15v, and requires a 24v supply. Even though the new controller was going to be for Ben, a guy sent me some money, basically bribing me to let him try it! haha. I figured that it's better to get it tested than not, so I ordered the rest of the parts and will be building it in the next week or 2. After trying this approach, which should work fine, I'm going to switch to a high side drive and try that out.
