After the fiasco mentioned in the last project log, a rework had to be done with powering/controlling the bubble machine. To address the need of beefier wires I cannibalized a power cord. I did give the L293D another shot with the wiring upgrade, but the voltage drop from the driver was still too much. I grabbed a 2 channel relay board I had lying around link to relay board here. The glorious re-configuration photo:

After I got everything reconfigured I started it up again and when it started running . . .

. . . it worked gloriously!

It's still a bit of a mess, but at least it works. By the way, the bubble machine that I'm using can be found here: https://www.walmart.com/ip/Way-to-Celebrate-Mini-Bubble-Machine/28038976
