Nick Sayer @ hackaday.io build a SD card RAID USB storage board. He writes: This project is a hardware mechanism to provide secure "two man control" over a data store. It is a USB microSD card reader, but it requires two cards. The data is striped in the style of RAID 0, but the data...

A small and inexpensive USB-based curve tracer used for troubleshooting electronics in the style of the Huntron Tracker 2000. by Jason Jones: This documents a USB-based curve tracer based on the PIC24FV16KM202, which is a modest 16-bit microcontroller. The board uses a PC screen OR...

iCircuit Technologies had produced the iCP12 usbStick, a mini size 28 pin USB PIC IO development board and a good tool for signal monitoring (as oscilloscope), data acquisition and circuit troubleshooting at 1mSec/Samples period. The iCP12 usbStick is a PIC18F2550 based USB...

The Micro Maestro is the first of Pololu’s second-generation USB servo controllers. The board supports three control methods — USB for direct connection to a PC, TTL serial for use with embedded systems, and internal scripting for self-contained, host controller-free applications —...

Ashwin K Whitchurch, Venkatesh Bhat, and Manikandan S @ hackster.io build a PC based ECG,Respiration & SpO2 monitor. We introduced the HealthyPi as a HAT add-on for the Raspberry Pi, turning it into a full-featured, medical-grade open patient monitor. However, we realized later...

Bob tipped us with his latest article. He writes: Back when I was developing the PSU burner, I wanted to have the Analog Discovery isolated from the common ground, to avoid noise and other issues. Since I did not have a way to do this, I ended up using a laptop on battery for...

Jesus @ jechavarria.com tipped us with his latest project. He writes: For several months I’m working with FONA808 modules from Adafruit to make a portable, web-based locating system. This modules are based on the SIM808 module from SIMCOM manufacturer, and integrates both GSM and...

In order to be able to upload Arduino sketches directly to the ATtiny84 over USB without the need to use a programming device, Shawn Hymel, an electrical engineer at Sparkfun Electronics, had published a guide showing how to install the micronucleus bootloader, which supports virtual USB...
