Daniel Eindhoven build a usb powered Teslacoil able to produce small sparks. The coil of the device is printed on the board! A new and improved PCB spiral Teslacoil. This Teslacoil has etched windings on a print circuit board. It has a USB interface which also powers the coil. The resonance frequency is about 4MHz. […]
Making of a New Nixie Tube
https://www.electronics-lab.com/making-new-nixie-tube/
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 engineers, glassblowers and machine operators. I […]
Arduino Weather Station with DHT11 and BMP180
https://www.electronics-lab.com/arduino-weather-station-dht11-bmp180/
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 because its readings are […]

4-port NanoHub – tiny USB hub for hacking projects
https://www.electronics-lab.com/4-port-nanohub-tiny-usb-hub-hacking-projects/
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 (effectively tripling its usefulness; providing 3 […]
ESP8266 based e-paper WiFi weather station
https://www.electronics-lab.com/esp8266-based-e-paper-wifi-weather-station/
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 data over WiFi and then updates the display. Daniel […]
STMicro Introduces 20 Cents MCU in 8-Pin Package
https://www.electronics-lab.com/stmicro-introduces-20-cents-mcu-8-pin-package/
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 has small package and little number of pins, but still it embeds […]
