FOVEA is a wearable embedded analyzer — a multimeter targeted at embedded electronics with wrist-worn convenience. FOVEA, their wearable embedded analyzer does a few primary things to make embedded work easier: (a) It moves the multimeter display to a location that’s much closer to where the probes are being held, and also with almost the […]

Over the years we’ve covered quite a few Raspberry Pi based arcade cabinets, and admittedly many of them have been fairly similar. After all, there’s only so much variation you can make before it stops looking like a traditional arcade machine. But even still, we never tire of seeing a well executed build like the one

There are times you find yourself looking for a relatively high voltage (100V to 200V often in my case) but low current DC power supply. I have zener diodes that are higher than 30V, which makes the lab supply useless, and filament LEDs with forward voltage over 60V. When I need to test them quickly,

In this article, we’ll develop firmware that will serve as the basis for high-precision, high-speed signal generation. I recently designed an arbitrary waveform generator (AWG) PCB that is built around a C8051F360microcontroller and a TxDAC from Analog Devices. These two ICs communicate via a parallel interface that allows me to generate higher-frequency analog signals by seeking

The Idea Over the last summer my sons and I rebuilt our entire pool system. It started with a problem with the water lines and valves that we inherited when we got the house, filter issues and a basically inept pool company that was a holdover from when we got the house. Once it started

For instructions for compiling the and using Infinite Noise TRNG driver, go to the software sub-directory, and read the README file there. Both Linux and Windows are supported. The Infinite Noise TRNG is a USB key hardware true random number generator. It uses what I call a “Modular Entropy Multiplier” architecture (previously Infinite Noise Multiplier
