WISP – Re-programmable Microcontroller That Runs On Energy Harvested From Radio Waves
https://www.electronics-lab.com/wisp-re-programmable-microcontroller-runs-energy-harvested-radio-waves/
A new research initiative between the University of Washington’s Sensor Lab and the Technical University of Delft in the Netherlands has created a microprocessor that can power itself through stray radio waves and receive programmable updates in the same fashion. While the RISC-derived 16-bit microcontroller CPU is very weak compared to modern standards, it’s much more powerful […]

https://www.electronics-lab.com/esp32-wifi-weather-station-nextion-display/
Our friends at educ8s.tv uploaded a new video about how to build a ESP32 Wifi enabled weather station: In this video, we are going to make this. It is yet another weather station project I know, but this time we use the new ESP32 chip! We also use the new BME280 sensor which measures the […]
TSL2540 Ambient Light Sensor matches eye-response
https://www.electronics-lab.com/tsl2540-ambient-light-sensor-matches-eye-response/
ams (Graz, Austria) has posted details of the TSL2540, a very-high sensitivity light-to-digital converter. Evaluation kit is available: The TSL2540 is a very-high sensitivity light-to-digital converter that approximates the human eye response to light intensity under varying lighting conditions and transforms this light intensity to a digital signal output capable through a 1.8V I²C interface. […]
PcbDraw – KiCAD board into a nice looking 2D drawing
https://www.electronics-lab.com/pcbdraw-kicad-board-nice-looking-2d-drawing/
Convert your KiCAD boards into nice looking 2D drawings suitable for pinout diagrams. Never draw them manually again! [via] Jan Mrázek created a Python script that takes a KiCAD board (.kicad_pcb file) and produces a 2D nice looking drawing of the board as an SVG file. This small Python script takes a KiCAD board (.kicad_pcb […]
USB powered – PCB TeslaCoil

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 […]
