DIY Arduino hot air SMD rework station.

This tester can be used for NiCd, NiMh, and all flavors of Li-Ion rechargeables.

An old CB transceiver is converted to the 50MHz amateur band using an Arduino Pro Mini, DDS, PLL and OLED display.

Cool little Pocket Metal Locator sensitive enough to identify small nails and tacks in wood with four independent search coils and LEDs.

Use FreeRTOS (simple, easy, robust, & optimised for the Arduino IDE) to reduce the power required for battery or low power applications.

An Arduino powered floppy disk controller and reader/writer for making and writing disk images from and to old AmigaDOS floppy disks.

Use a 3D printed encoder wheel, LED, and 2 photocells to demonstrate how a quadrature encoder works.

Protect lithium polymer battery pack from over discharge.

A soft switch with integrated energy monitoring enabling spark-free switching for electric vehicles and drones.

An Arduino interface to communicate with devices using the LANC (Control-L) protocol such as many Sony and Canon cameras/camcorders.

I needed to set a large number of ds18b20 sensors up and I had to record the address and position of each sensor.

This project is about a shortwave trasmitter from 3 MHz to 30 MHz. It uses the SI5351 oscillator from Silicon Labs controlled by Arduino.

This is an Arduino library for the SI47XX, BROADCAST AM/FM/SW RADIO RECEIVER IC family from Silicon Labs. This library also has SSB support.

This is an Arduino Library to control the AKC695X / M695X DSP radio devices.

This is an Arduino library for the SI4844, BROADCAST ANALOG TUNING DIGITAL DISPLAY AM/FM/SW RADIO RECEIVER, IC from Silicon Labs.
