The EVE Alpha - a breakout board for several wireless radio modules for the Raspberry Pi - hopes to change that with their Kickstarter campaign. The idea behind the EVE is to provide a link between low-power radio modules found … [Read more...]

BPSK on 433 MHz European ISM band

[WaveRider] is using a type of phase shift keying called BPSK to transmit digital sound and video for remote telemetry. Though a higher signal to noise ratio (SNR) is generally sought after with communications, legal limitations are imposed on total radiated power. To balance the two headed beast, he opted out on frequency shift keying due to binary shift keying's ability to work with lower SNR. … [Read more...]
