I started to design a programming rig for the MDBT50Q-1MV2 module. I paused to see if anyone made a programming jig, but I did not see anything. I plan to continue the design and determine which components I need to support the module.
I tested an ESP32 module with wireless power, and I could ping it via Bluetooth, but the power receiver became dangerously hot. I had the same problem with three other units, so I need to run further hardware tests. I found and modified a Universal Asynchronous Receiver-Transmitter (UART) sketch and recognized a designated character, enabling two-way communication, which should be enough for rudimentary functions.
The overheating wireless power receivers were problematic, and I wanted to test if the 20V transmitting coil was part of the problem. I soldered a 5V transmitter, and when I powered it, the chip overheated, melted the solder, and fell off the board. The second try worked fine, but I could not power the ESP32 board without finicky coil alignment, which also caused overheating. I will have to find a reliable receiver.
I discarded the ESP32 as a viable microcontroller since I could not get one to power up without overheating. The MDBT50Q-1MV2 modules worked, so I started making a programming harness for one. Doing this much work would be excessive for a hobbyist, but they should not have to make a harness; they should just print the one I was making. I drafted the layout from the datasheet and compared the two to ensure they matched.
I wrote the quiz for Thrash (2026), and my justification for the questions is "garbage in, garbage out." The movie was too high-budget to be a cult classic, and too poorly executed to be campy. I have not spoken to anyone who enjoyed it.
This was Critical Affection's first episode with a surprise guest! Fish Lee jumped into the show to defend Fred, who argued that Thrash (2026) was not an atrocious movie, but rather a fun B-movie. The debate was hot, and everyone got their say, but it was madness and so much fun.
The rest of the summary posts have been arranged by date.
