Yesterday evening I finished the third channel, this time a negative channel. So now I have channels 1, 2, and 4 completed (1 and 2 are 5A positive channels, 4 is a 1.5A negative channel). I had channel 3 soldered up previously, but there was a problem with it so I will need to try again.

The negative channel is working well from a hardware point of view, but the software needs some work. This is the first time that I had hooked a negative channel up to my controller, and the software does not account for negative vs. positive.

A (very bad) picture is attached below.

Next steps (in no particular order):

• Solder up the last channel
• A whole bunch of programming
• Wooden enclosure (including making some jigs for the wood working, so this may take a while)
