TEENY TINY BLUETOOTH TRANSMITTER RUNS ON LESS THAN 1 MW

TEENY-TINY BLUETOOTH TRANSMITTER RUNS ON LESS THAN 1 MW

You’re probably swimming in Bluetooth radio signals right now. But none of those are coming from the smallest, lowest-power end of the Internet of Things. These battery-powered and energy-harvesting millimeter-scale sensors are meant to last for years without needing replacement, but their radios can’t muster the energy needed to communicate using even the lowest energy […]

World’s first fully digital radio transmitter built purely from microprocessor technology

World’s first fully digital radio transmitter built purely from microprocessor technology

For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a set of patented algorithms without using conventional analog radio circuits in any way whatsoever. This breakthrough technology promises to vastly improve the wireless

Tiny UHF Tracker Transmitter

Tiny UHF Tracker Transmitter

This is a little circuit that could be used to track an object up to 400m. It is essentially an SAW stabilized OOK modulated RF transmitter. The modulation is done with two low frequency ultra low power oscillators that activate the transmitter every two seconds for a short period. With the setup shown here I
