Rombus pinball – a LattePanda mini pinball machine

Matt Brailsford (aka Circuitbeard) has a nice write-up about building his mini pinball machine with a lattepanda core running dual monitors: I generally start my projects by thinking about the hardware that I’m going to want to use as I’ll need to know sizes when it comes to the design phase. My first thought was to […]

PSOC – design and implementation of a 12 lead portable ECG

Alex Lao and his team at McMaster University have developed a compact, battery powered, 12-lead electro-cardiogram: During the academic year of 2016-2017 at McMaster University, in conjunction with Dr. DeBruin, Christina Riczu, Thomas Phan and Emilie Corcoran, we developed a compact, battery powered, 12-lead electro-cardiogram. The project won 1st place in the biomedical category at […]

Solid-state joystick

Paul Gardner-Stephen writes: Early in the year, one of my colleagues, Damian, showed me one of these strain-gauge solid-state joysticks that they were using as part of the undergraduate engineering curriculum. Their goal was to teach the students how to read strain-gauges. But I immediately saw the applicability for making a no-moving-parts super-robust joystick for […]

Valve’s “Lighthouse” optical tracking system

Travis stumbled across an interesting project at Bay Area Maker Faire, the Lighthouse Optical Position Tracking by Alan Yates of Valve. He writes: While walking around the Bay Area Maker Faire this weekend, I stumbled across an amazing piece of technology: Valve’s “Lighthouse” tracking system. Valve’s demos were (supposedly) a major contributor to Oculus’ fundraising […]

Arduino time lapse – camera pan device

An Arduino camera pan device project from Bajdi Electronics: I own one of these small action cameras (SJcam SJ4000). I bought it because it’s small, and easy to take with you wherever you go. To make nice stable videos I mount it on a mini tripod. This got me thinking that it would be fun to have […]

Simple 3D gesture control IC by Microchip

Microchip simplifies 3D gesture IC: Housed in an easy-to-manufacture SSOP28 package, the MGC3030 expands the use of highly sought after 3D gesture control features to high-volume cost-sensitive applications such as toys, audio and lighting. The simplicity of gesture-detection integration offered by the MGC3030 is also achieved through the company’s free, downloadable AUREA Graphical User Interface […]

Blueprintf – a bluetooth serial monitor

Bob Alexander of Galactic Studios made this bluetooth serial monitor for embedded microcontroller projects, the Blueprintf: One way of debugging microcontroller-based projects is to send messages out the UART serial port. Then, a UART-to-USB interface can feed the messages into your PC for display. But I wanted a small, portable device for viewing serial data without […]

WiFi globalCALCnet with the Spark Core

A wireless calculator networking with WiFi gCn using the Spark Core.  KermMartian of Cemetech writes: This current project achieves all the goals of that project, and more: it provides a computer-free way to connect calculators to the internet, and lets the calculators independently configure the bridge device as well. The two components that were necessary to […]

Acoustic impulse marker

Adam Wrobel and Michael Grisanti of Cornell University built this device that tracks sound impluses: The core of our system is hardware based analog circuit, which filters, amplifies, and processes the sounds obtained from the microphones. By utilizing hardware for this, we are able to high frequency signal processing without taxing the microcontroller. Also, we remove […]

Wearable pupillometer could detect dangerous diabetic condition earlier

Mang Ou-Yang and his team at National Chiao-Tung University have developed a wearable pupillometer. It could detect dangerous diabetic condition earlier: Compared to the existing diagnostic techniques, the pupillometer is a more reliable, effective, portable and inexpensive solution for diagnosing diabetic autonomic neuropathy in its early stages,” said project leader Mang Ou-Yang, of National Chiao-Tung […]

OTTO – The hackable GIF camera

Gustavo Huber and his friends announced that OTTO – the hackable GIF camera is now being offered on Kickstarter! OTTO lets YOU decide how it takes pictures. Besides being the only camera that makes animated GIFs, OTTO’s an image making machine that can transform into hundreds of different cameras with a quick tap. GIFs, time lapses, impromptu […]
