I'd pretty much had enough of Epic Photo Ops mismanagement and generally avoided them for the past couple of years, but really wanted to try for a photo with Mary Elizabeth Winstead and they were the only game in town. As usual, they screwed it up royally and I missed out. So business at usual for Epic FuckUps. Con organizers, go with ANYONE BUT EPIC FUCKUPS for photo ops, please.
Our microwave oven died in a peculiar fashion this morning. While cooking, it would turn itself off every few seconds, then come back on and pick up where it left off. I guessed it was the usual failure mode for electronics: electrolytic capacitors. I opened it up and saw there were only four of them. I had those values in stock, swapped them in, and that fixed it!
The tractor battery swap mostly works, but it's weird. The blade motors run just fine, but the wheel motors run very slowly at full charge and slowly speed up. I don't know if it's an issue with the ESCs (same ESCs as the blade ones), the control CPU, or perhaps the accelerator position sensor. May have to do some detailed debugging.
