In this video, I’m building a LoRaWAN Class A sensor node using an ESP8266, BME680 environmental sensor, and REYAX RYLR993 ...

Oddly Specific Objects founder Joey Castillo has designed a couple of interesting open hardware projects over the years.

Over time, I've found different uses for it, and the most recent way that I'm using it is likely the one I'll settle on.

If you think smart home, you might not imagine a temperature sensor, but there's a lot you can achieve with one of those and ...

A dual resonator graphene sensor measures pressure with exceptional precision and stability, using built-in temperature ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...
