An Arduino powered floppy diskreader/writer for making and writing disk images from and to AmigaDOS floppy disks, works winUAE too

Protect lithium polymer battery pack from over discharge.

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

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

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