VFD displays are beloved for their eerie glow that sits somewhere just off what you’d call blue. [mircemk] used one of these displays to create an old-school VU meter that looks straight out of a 1970s laboratory. The build uses an Arduino Nano as the brains of the operation, which uses its analog inputs to process […]

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Arduino code showing how handy this can be for battery-powered projects. The classical way to measure a system’s voltage is to connect one of your MCU’s

It has been announced this week that Arduino Pro has teamed up with Patti Engineering to enhance the digital transformation of manufacturing processes. This collaboration is a key component of the Arduino Pro System Integrators Partnership Program, which is designed to incorporate Arduino technologies into professional projects, thereby elevating manufacturing productivity and quality. Manufacturers are currently navigating the shift towards Industry 4.0,

What is it about solenoids that makes people want to make music with them? Whatever it is, we hope that solenoids never stop inspiring people to make instruments like [CamsLab]’s copper pipe auto-glockenspiel. At first, [CamsLab] thought of striking glasses of water, but didn’t like the temporary vibe of a setup like that. They also considered

Maybe it’s just us, but isn’t it kind of amazing that in a world of pretty darn realistic games, PONG is still thrilling to play? This 1D implementation by [newsonator] is about as exciting as it gets. It works like you’d probably expect — the light moves back and forth between the two players. Keep it
It is hard to describe the Brother SuperPowerNote. It looks like a big old Z80-based laptop, but it says it is a notebook. The label on it says (with lots of exclamation marks) that it is a word processor, a communications system, a personal scheduler, and a spreadsheet organizer. Brother also promises on the label
Following on the heels of their Raspberry Pi 5 launch and some specifications for their RP1 all-in-one peripheral chip, the Raspberry Pi folks have now released an update to the HAT peripheral hardware specification reflecting the new model. Called the HAT+, it represents a major step forward with some significant changes. Most visible will be changes to
We’ve enjoyed several videos from [Chornobyl Family] about the computers that controlled the ill-fated nuclear reactor in Chornobyl (or Chernobyl, as it was spelled at the time of the accident). This time (see the video below) they are looking at a high-speed data storage device. You don’t normally think of high-speed and paper tape as going
Back in 1978, the world was a bit different. There was no Raspberry Pi, no Internet, and not even an ESP32 to build projects with. And rather than order electronics kits from Tindie or Adafruit, [Dr. Francitosh] selected this binary clock with his mother from a catalog, and made the order via mail. Simpler times. The
For those who grew up with a cell phone in their hand, it might be difficult to imagine a time where the phone wasn’t fully integrated with voicemail. It sounds like a fantastical past, yet at one point a separate machine needed to be attached to the phone to record messages if no one was
