Dalibor Farny shows us how he hand make new Nixie tubes on this interesting video! The nixie tube is a vintage display device which had been used until 70s when it was replaced with LED displays. The complex knowledge of manufacture of nixie tubes literally died with tube factory's...

In the previous tutorial I showed you how to build a weather station using only the DHT11 sensor and I said the readings from this sensor is fairly accurate. In this tutorial, I will be using the DHT11 to measure only the humidity and BMP180 to measure pressure and temperature. That’s...

Muxtronics @ tindie.com sells their 4-port NanoHub board: The NanoHub 4-port is a natural evolution of the original 2-port NanoHub - a truly tiny USB hub to use in the most cramped of spaces. Nanohub 4-port is bigger and better! Even though it boasts twice as many downstream ports...

Erich Styger documented his experience building Daniel Eichhorn’s e-paper weather station with a custom enclosure: Using e-paper for a weather station is an ideal solution, as the data does not need to be updated often. By default, the station reaches out every 20 minutes for new...

STMicro has launched STM8S001J3, a new 8-bit micro-controller that sells for $0.20 per unit in 10k quantities. STM8S001J3 is also the first STM8 MCU offered in 8-pin package (SO8N), and should compete with some of the Microchip Attiny or PIC12F series micro-controllers. STM8S001J3...
