There are plenty of “robot” projects out there that are really just a small remote control platform of some sort. We often like to think of robots of having some sort of autonomy though. [Luca Fagioli ...

Build a tiny ESP32 OLED keychain with a 1.3-inch display and custom 3D-printed enclosure. Wire the ESP32 S3 and program it via Arduino.

Heatbit's Bitwater turns your water heater into a Bitcoin miner. Learn how this dual-purpose heating element works and when you can get one.

The Bitwater element swaps a tank's resistance wire for 20 mining chips, and Heatbit says it uses the same electricity to heat the water.

Large rooms of 300 square feet or more are particularly tricky to keep warm in the winter—and high ceilings, hard-to-reach corners and drafts greatly add to that challenge. To choose the best space ...

Heatbit, previously known for its Bitcoin mining-powered space heater, has announced the launch of Bitwater, a water heater ...
