What do cats get up to in the 30 minutes or so a day that they’re awake? Being jerks, at least in our experience. But like many hackers, [Brent] wanted …read more Continue reading Exercise Wheel Tracker Confirms Suspicions About Cats
While it would be a mistake to think there are any firm rules for what constitutes a cyberdeck, we can at least identify some common traits that would seem to …read more Continue reading 2022 Cyberdeck Contest: RPG Character Tracker
Unless you’re reading this from the middle of the ocean or deep in the forest, it’s a pretty safe bet there’s WiFi packets zipping all around you right now. Capturing them is just a matter of having the right hardware and software, and from there, you can get to work …read more

We’re not sure how many of you out there own a boat large enough to get its own integrated computer network, but it doesn’t really matter. Even if you can’t use this project personally, it’s impossible not to be impressed with the work [mgrouch] has put into the “Bareboat Necessities” …read more
The M5Stack is a plastic box loaded up with an ESP32, a display, some pin headers, and a few buttons. Why does this exist? It’s a platform of sorts, and we’ve seen people adding LoRa to the M5Stack as well as thermal cameras. Hot from random online retailers is the …read more
LoRa is the new hotness in low-power, long-range communications. Wanting to let the packets fly, [Xose] was faced with a frequecny problem and ended up developing a Europe-friendly LoRa module for the M5Stack system. The hardware is aimed at getting onto The Things Network, a LoRa based network that provides connectivity for IoT devices. While there was an existing M5Stack module for LoRa, it only supported 433 MHz. Since [Xose] is in Europe, an 868 MHz or 915 MHz radio was needed. To solve this, a custom board was built to connect the HopeRF RFM69 series of modules to the …read more

Thermal cameras hold an enduring fascination as well as being a useful tool for the engineer. After all, who wouldn’t want to point one at random things around the bench, laughing with glee at finding things warmer or colder than expected? But they’ve always been so expensive, and a lot of the efforts that have sought to provide one for little outlay have been rather disappointing.
This has not deterred [Offer] though, who has made an extremely professional-looking thermal camera using an M5Stack ESP32-based computer module and an AMG8833 thermal sensor array module in a 3D-printed case that copies …read more
