Hardware

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.

If any of these projects have been helpful to you or your community, please donate to help keep this work alive and available.

Please contribute to keeping information on Free & Open Communications systems available for all.
