I made an alarm clock that blows up capacitors to wake you up. There are more details on the Github repo but it's made from an esp32-c3 as the microcontroller, with 3 capacitor slots. There are relays on each capacitor slot to put 15v reverse voltage on the capacitor, with 5.1 ohm resistors on each slot for current limiting in case the capacitor shorts out. I also chucked in an SSD1315 OLED to show the time and a menu to configure it, although there's a web UI as well. The esp32 also means you can fetch the time from NTP. It also functions as a small heater since I used LDOs to step down 15v…

A clock app for my Apple ][ clone in 6502 assembly, using interrupts generated by an inductive proximity sensor and a physical pendulum clock. I wanted to polish the code a bit more before sharing (I especially dislike the self modifying code part), but the computer seems to have developed a hardware problem lately and it keeps crashing (bad RAM chip most likely), so I am sharing as is.

Hello all! Build clean, minimalistic analog clock webpage to Cloudflare Pages. This is for (maybe): - kids to learn - for second monitor - old tabled on shelf - .. Themes and screen wake lock buttons with auto-hide. Goal is to keep it as clean as possible. This possible makes no sense, but for a domain of $10/y this is cheap site for me to keep and see how it lives on.
