[minh7a6] loves the Adafruit Feather, but sees some room for improvement. First is the matter of 5V tolerance. While just about everything is available in a 3.3v range these days, sometimes it’s just nice not to have to care. The main controller on the Feather is plenty powerful, but its intolerant pins just wouldn’t do so […]

[Engineer2you] built a nixie tube clock and claims it is the simplest design. We felt like that was a challenge. In this design, the tubes are set up as a matrix with optoisolators on each row and column. With 60 segments, the matrix allows you to control it all with 16 bits. There are six columns, each

My hobby and passion is to realize physics projects. One of my last work is about ultrasonic sonography. As always I tried to make it as simple as possible with parts you can get on ebay or aliexpress. So let’s take a look how far I can go with my simple items… I was inspired

Step 1: Demonstration of Sensitivity On the video you can see the manufacturing process and the sensitivity of shocks Step 2: Components Otherwise, the seismometer itself consists of two parts, a mechanical tremor detector, and an electronic part that turns these tremors into electrical signals, amplified them and converts them into digital signals, which we

It’s fair to say that the Nintendo 64 and GameCube both had the most unique controllers of their respective console generations. The latter’s gamepads are still in high demand today as the Smash Bros. community continues to favor its traditional control scheme. However, both controllers can easily be repurposed for musical means, thanks to work by [po8aster].

Flashing LEDs are all well and good, but they’re even better if they can sync up with ambient sounds or music. [mircemk] has built the LUMAZOID visualizer to do just that, relying on some staple maker components to do so. The build is open-source, and designed to work with strings of 60, 120, or 180 WS2812B

Sasa Karanovic build an analog monitoring system that is able to show your computer’s resources on 4x beautiful dials. He writes: In the video above, you can see first a power up sequence where all four dials go from zero to 100% and back to zero after which they start showing real time CPU, Memory, Network

For those who don’t know Nixie tubes are electronic devices used for displaying numbers and other character using glow discharge. They date back to 1950s not used commercially anymore. Currently they do experience second life though, as people do tons of cool projects. In this instructable I will show you how to glow individual digits

The REF_XDPS21071_45W1 from Infineon is a 45W USB-PD type C charger reference design in a small form factor. The reference design has been developed to demonstrate the performance by meeting various regulatory limits as well as allowing for small form factor designs. It features Infineon’s digital flyback controller XDPS21071, 700V CoolMOS™ P7 Superjunction MOSFET (IPD70R360P7S), OptiMOS™ PD synchronous-rectification MOSFET
