Just Vibe It I crafted a whimsical single key keyboard ideal for vibe coding! It's powered by a TPS2117-equipped PCB, offering slick battery-to-USB switching. Tried out low profile Cherry switches, but faced some stabilizer challenges with bigger keycaps. Check out the final fun in my GitHub repo and video! 04 July 2025
I got this feeling bezos is watching Discovered my Hue switch battery performance is correlated with room temperature after a nifty web scrape of Amazon's device usage history. While it's a given that batteries are temperature-sensitive, actual data from my own living room provided a neat confirmation, graphing a daily pattern. Wanted to go green with a rechargeable lithium coin cell, but the voltage risk to the ATmega256RFR2 on the PCB is a no-go. For now, it's back to the humdrum world of regular coin cells and unexciting battery charts. Dive into the video for a deeper geek-out on this! 29 March 2024
Interesting LED Curtain Dove into hacking an LED curtain and discovered that despite lacking visible daisy chaining, it's hackable! With LEDs pre-programmed for their position, it can receive collective data and recognize individual signals. Flashed WLED firmware onto an ESP32 and, voila, it lit up beautifully, even supporting 2D grid patterns for cool visuals. The key components: a BLE SoC, buffer IC for level shifting, and a curious way of LED data handling that's cleverly efficient. 12 December 2023
