B-SENSOR: DIY PRESSURE CUSHION

This project examines how interface pressure is a key risk factor in the development of pressure ulcers. Visual feedback of continuous interface pressure between the body and support surface could inform clinicians on repositioning strategies and play a key role in an overall strategy for the prevention and management of pressure ulcers. eTextiles are made …

CORE ROPE MEMORY MAKES ONE OF THE ODDEST LED FLASHERS WE’VE EVER SEEN

If you’ve heard of core rope memory, it will probably be in the context of vintage computing equipment such as Apollo-era NASA hardware. A string of magnetic cores and sense wires form a simple ROM arrangement, which though long-ago-superceded by semiconductor memory remains possible to recreate by the experimenter. It’s a path [Nicola Cimmino] has …

PacketMonitor32 – An ESP32-Based Packet Monitor with OLED

PacketMonitor32 – An ESP32-Based Packet Monitor with OLED

Wi-Fi Packet Monitors are usually a computer program or sometimes a piece of computer hardware that can be used to intercept and log traffic over a Wi-Fi network. My favorite software tool of all is the popular Wireshark which I have used several times for hacking Wi-Fi based hardware, like integrating the common Wi-Fi smart socket …

A FAREWELL TO YOUTUBE SUB COUNTERS SET TO BREAK WITH API CHANGE

Of all the things you never would have guessed you’d need just ten years ago, a YouTube subscriber counter would probably rank highly. You would have guessed that the little hits of dopamine accompanying each tick upward of a number would be so addictive? As it turns out, lots of people wanted to keep a …

Cinque, Combining RISC-V With Arduino

Cinque, Combining RISC-V With Arduino

After announcing “HiFive1” at the end of 2016, SiFive is introducing its second RISC-V based development board “The Arduino Cinque“. It is the first Arduino board that is featuring RISC-V instruction set architecture. Arduino Cinque is running SiFive’s Freedom E310, one of the fastest and powerful microcontrollers in the hardware market. It also includes built-in Wi-Fi …

CADLAB.io – A True Version Control For Managing Hardware Projects

Version control is a system that records changes of a file or set of files over time so that you can recall specific versions later. Version control was developed to help teams work on tasks together in a more collaborative way. In the last few years, version control platform has often been focused on software-based projects. Git is …

HIGH PRECISION ANALOG IO WITH DIGITAL PINS

Reading the temperature of your environment is pretty easy right? A quick search suggests the utterly ubiquitous DHT11, which speaks a well documented protocol and has libraries for every conceivable microcontroller and platform. Plug that into your Arduino and boom, temperature (and humidity!) readings. But the simple solution doesn’t hit every need, sometimes things need …
