https://www.electronics-lab.com/sozu-monitoring-system-harvests-activity-energy-runs-without-batteries/
A team of Researchers at Carnegie Mellon University’s Future Interfaces Group have developed self-powered radio tags called Sozu, which enables building-scale activity sensing, without the need for line-of-sight and at a very low cost. They claim a 99 percent detection rate and “almost no false positives.” The team of researchers includes Yang Zhang, Yasha Iravantchi, Haojian […]
Ultrastable UHF transmitter – A super Tiny Radio Transmitter
https://www.electronics-lab.com/ultrastable-uhf-transmitter-super-tiny-radio-transmitter-can-used-spy-120-meters-away/
Dire situations require unpleasant solutions, an excellent example of this statement is spying and we have seen what the NSA has done in this regard. It goes against proper ethical character, however, it might be needed in certain circumstances. Usually, the first thing a person who wants to spy would do would be to check […]
Tiny UHF Tracker Transmitter

TomTechTod @ instructables.com writes: 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 […]
Send & Receive Radio With A Single Chip
https://www.electronics-lab.com/send-receive-radio-single-chip/
Fitting transmit and receive capabilities of radio signals into one device may be impossible without using a significant filter, which is needed to isolate sent and received signals from each other. The major obstacle to achieve that is the weakness of the received signal compared with the much stronger transmitted signal. However, researchers from Cornell […]
Wireless communication between two Arduinos using inexpensive RF modules
https://www.electronics-lab.com/wireless-communication-between-two-arduinos-using-inexpensive-rf-modules/
Raj from Embedded Lab has posted a new article exploring an easy wireless communication setup between two Arduinos using low-cost ASK RF transmitter and receiver modules. He used a 433MHz Tx/Rx pair with two Arduino boards to illustrate how to construct a low-range wireless temperature and humidity monitor. Wireless communication between two Arduinos using inexpensive […]
