🎯 What is FROST-T? FROST-T (FROST Terminal) is a complete implementation of the FROST (Flexible Round-Optimized Schnorr Threshold) signature protocol with two major innovations: Simulated LoRa ...

The theme of the contest focused on developing Edge AI solutions utilizing the limited computational resources of microcontroller boards. Our project is inspired by the widespread harm caused by war ...

CiferTech has recently introduced the nRFBOX V2 ESP32-based wireless hacking tool designed for spectrum analysis, jamming, BLE device emulation, and more. The device is built around an ESP32-WROOM-32U ...

I needed to come up with a communications device to transmit a handful of bytes, every hour, from a small off-grid solar system to my shop about 150 feet away. The first thought was Wi-Fi, but I ...

Remote patient monitoring is a critical tool for diagnostics and therapeutics, especially in sparsely populated areas. Wearables with clinical-grade sensing fidelity provide a suitable platform ...

Considering it's been almost impossible to buy a Raspberry Pi for about a year because of supply chain shortages, it's remarkable how many people continue to create interesting and increasingly useful ...

Using a small custom PCB, a Raspberry Pi Pico 2 microcontroller, a scintillator (typically NaI (Tl)) and SiPM you can build your own gamma spectrometer! The needed processing and multi-channel ...

I was having a chat recently with someone, and it surprised me that she had an amateur radio license. I suppose it shouldn’t have come as much of a surprise; after all, getting a ham radio license is ...

We were struck by how attractive [mircemk’s] Arduino-based frequency counter looks. It also is a reasonably simple build. It can count up to 6.5 MHz which isn’t that much, but there’s a lot you can do ...

One challenge of teaching chemical analysis is the proliferation of sophisticated, but often impenetrable, instrumentation in the modern laboratory. Complex instruments, and the software that runs ...
