This outdoor-friendly radio can evolve and improve over time.
The PSDR, which some of you may remember was a Hackaday Prize finalist, is a standalone pocket-sized software defined radio ideal for those looking to stay connected while hiking or traveling abroad. Created by Michael Colton, the open-source device was originally designed for backpacking use by ham radio operators with complete coverage up to about 30MHz.
The LiPo battery-powered device — which recently made its Kickstarter debut — packs a 168Mhz ARM Cortex-M4-based MCU, a color LCD for its waterfall display, a single knob for selecting items from the screen, dual DDS frequency synthesizers, a built-in microphone and speaker, a magnitude and phase measurement chip, digitally-controllable instrumentation amplifiers, vector network analysis and a GPS receiver — all housed in an aluminum case.
The self-contained radio boasts an innovative interface equipped with pair of AT42QT1010 capacitive touch sensors, in addition to a USB connector for uploading firmware, keyboards and possibly remote Internet use.
“It’s built for rugged portable use. It is designed to be a flexible platform for development, a learning aid, and and a useful instrument for electronics enthusiasts,” Colton shares.
Pending all goes to plan, the Maker aspires that with the necessary crowdfunding, he will be able to enhance the PSDR’s design to include a media player, an e-reader and picture viewer, improved audio, GPS mapping, and serve as as an emergency location beacon.
