I added a serial setting to change brightness. The clock drew approximately 3.7 watts at full power and 0.5 watts with no lights. I also wrote two new modes: one filled up the clock with red lights and the other emptied green lights. Next, I want to change the settings over Wi-Fi.
I added Wi-Fi support to change the colors, mode, and brightness. Wireless support was a big deal because every change happened in volatile memory, which disappeared when I dropped power. I prefer the default settings but am delighted to change them from the couch.
I appeared on Critical Affection again, and this time, we talked about Arcane, season two. The opinions were all over the board, and Mike (MostEPIC) had a very hot take about a "villain."
I have been considering building a submersible remotely operated vehicle. Now that I live in an apartment with a swimming pool, testing will be much easier than using natural water bodies. I aim to create a vehicle that seals soundly and operates from audible commands underwater, unlike typical submarines that rely on a buoy with a radio antenna. My design includes magnetically coupled propellers, eliminating the need for moving parts passing through the hull. I sketched a concept that resembles a bathtub over rounded chambers for motors and magnet wheels to provide stable movement. For the first prototype, I plan to use an empty bottle as the hull instead of 3D printing one.
I started modeling with the lower chamber, where I will wire the motors. The open chamber will be sealed with two halves that look like a holey medicine capsule, and the propellers will go over them on each side. I will not worry about a fancy hull design.
I modeled a propeller with adjustable fins and then created a mirror image since they have to spin in opposite directions. I can change the number of fins, their angle, and length to test different configurations.
The rest of the summary posts have been arranged by date.
