I am actively developing and maintaining a variety of hardware related to Free & Open Communications Systems. The following list serves as an entry point to further explore these efforts.
- RNode is a flexible, highly modifiable, self-replicating system for creating free and unrestricted digital radio transceivers, that respects user autonomy and privacy, and can be used for a variety of purposes.
- OpenModem is a very flexible and open-source packet radio modem and TNC. It is built on the proven reliability and performance of the MicroModem platform, but updated with all-round better components, a better DAC and ADC, a faster processor, and a much more powerful firmware.
- The Original RNode Design details the operation and functionality of the initial version of the RNode concept, the LoRa based open-source communications utility.
- Unduino1284p is an Arduino-compatible development, prototyping and control board featuring the powerful ATmega1284p MCU and onboard USB-to-serial converter, in a very small (but still breadboard-friendly) form-factor. The board is directly programmable from within the Arduino IDE, and using avr-gcc tools.
- MicroModem is an open-source implementation of a 1200-baud AFSK / Bell 202 modem on the popular ATmega328p microprocessor.
