Multiple synthesizer projects have been done for the Arduino, but few have been able to utilize the full power of the Arduino processor. DZL from GeekPhysical wrote a 4 voice wavetable synthesizer that is one of the more advanced software based synths for the Arduino. It has wavetables included (sine, saw, square and triangle) and […]

When a person owns the home they live in, often the only approval they need for modifications is from their significant other or roommate. In the worst case, maybe a permit is required. But those who rent their dwellings are far more constrained in almost every case, and when it comes to environmental controls, they

Matrix keypads are an excellent way of providing user input data into microcontroller-based systems. Keypads find applications in remote controls, standalone data-loggers, security systems, door entry systems, calculators, microwave ovens, etc. They are usually implemented as pushbutton switches arranged in a row and column matrix format to reduce the number of I/O connections. For example,

Here is a small personal project to brighten my home made from a cheap IKEA photo frame, and Arduino and a multicolor “NeoPixel” LEDs strip. The goal is simple: to realize a matrix of 12×10 big square pixels able to emit light in any color, and controllable from a smartphone. A simple demo video will

Combining embedded data-over-sound with cornerstone Wi-Fi audio technology for enhanced connectivity of smart consumer applications. Chirp, a pioneer of data-over-sound technology and Linkplay Technology, a leader in Wi-Fi audio solutions have today announced a technical partnership, delivering a turnkey solution for the frictionless, audio-based provisioning of smart-enabled consumer applications. Chirp’s ultrasonic machine-to-machine communications software enables any
I’m probably as guilty as anyone of reinventing the wheel for a subpart of a project. Heck, sometimes I just feel like working on a wheel design. But if that’s the path you choose, you have to think about whether or not it’s important that others can replicate your project. The nice thing about a bog-standard wheel

Signet HC is a secure USB drive built with open-hardware and free open-source software. It is an encrypted flash drive, a two-factor authentication (2FA) device and a hardware password and personal information manager, making it a portable solution to a variety of data security problems. Signet HC is physically secured, it requires a user taking physical action (press a button
Introduction It’s been so long since I had the idea for this project that I can’t remember why I had the idea in the first place. At least I blame it on the passage of time although this engineer is getting on a bit now so it could easily be memory rot on my part.

The UK in the 1980s was ground zero for the microcomputer revolution. Cheap computers based on 8-bit processors flooded the market, teaching a generation to program using built-in BASIC interpreters. Homes had devices like Sinclair’s ZX81 and Spectrum, while schools used Acorn’s BBC Micro. More about Innovation These weren’t like today’s PCs. They were designed
