DC Output Solid State Relay 10Amps 60V DC (Optically Isolated Input) This project has been designed around TLP250/352 which is Opto-Coupler IGBT/MOSFET Gate Driver from Toshiba and Mosfet IRFP260 from IR, This relay consists of optically isolated gate driver and low impedance...

SteveQuinn @ instructables.com show us how to create a heart rate monitor using an IR phototransistor and Arduino and display the data on a TFT screen. This Instructable documents how to create a simple heart rate monitor using Photoplethysmography with an IR phototransistor via...

This reference design is a low-cost development kit based on Kinetis EA series MCUs that allows faster prototyping and tool reuse. This evaluation board features either one of the KEA128, KEA64 or KEA8 MCUs, depending on the board version. This particular design uses KEA128. The...

baweja_akshay @ instructables.com has build a ATMEGA328 component tester that is able to test Resistors, Capacitors, Inductors, BJT, FET, Thyristors and more. Coming upon COMPONENT TESTER so it can test almost everything, obviously not the power components because they require more...

In this video educ8s.tv take a look at the WeMos D1: a Wi-Fi enabled Arduino compatible board based on the ESP8266 chip. First look at the WeMos D1 Arduino compatible ESP8266 Wifi Board -...

Johan @ johan.kanflo.com build his own Wifi webcam combining an Arducam Mini and a ESP8266 Wifi module. The result is the Esparducam board! Sometime ago I came across the Arducam Mini which is quite a nice camera module from UCTronics. It is a small PCB with a two megapixel...

MichielD99, a 16 year old Belgian teenage maker build this amazing laser engraver using Arduino UNO, two NEMA-17 stepper motors and stepper motor drivers. This laser engraver uses a 1.8W 445nm laser module, of course, this is nothing compared to the industrial laser cutters who use...

KF5OBS @ jaunty-electronics.com shows us how to build a minimalistic GPS datalogger. The GPS logger is based on the Arduino platform and stores raw NMEA sentences from pretty much any GPS module to a SD card. For a project I needed to log GPS information. I had various GPS modules...
