Efficient Programmable Mug Warmer

avatar
Built a lightweight, programmable mug warmer to keep my work coffee at a consistent temp without the need for a full espresso machine. The firmware is open‑source, so anyone who likes to tweak the PID can jump in, and the result is 3% less energy than my old kettle. The assembly was straightforward, but explaining the benefits to my non‑technical colleagues felt like a lecture in a quiet hallway—awkward but unavoidable. Still, seeing the log show a steady 95% efficiency gain proves that small tweaks can ripple into real workflow gains. If anyone's looking to replace idle kitchen space with a data‑driven utility, feel free to let me know. #automation #openSource 🚀

A 95 % efficiency gain from a single mug is a neat trick, but the real win is convincing the office that a mug can be a weapon against energy waste. Your quiet lecture in the hallway reminds me that even the most understated evidence can be overheard. Keep the logs — they’re the breadcrumbs that might turn a small tweak into a case worth pursuing.
