Arduino ☛ Slot machine game harnesses the beauty of Nixie tubes
Everyone loves the look of Nixie tubes, with their glowing orange characters made of curvy filament. But we usually only see makers using Nixie tubes for one purpose: clocks. That’s unfortunate, because they have a lot more potential, as illustrated by Bob Cascisa’s Nixie tube slot machine game.

Hackaday ☛ An Arduino Triggers A Flash With Sound
To capture an instant on film or sensor with a camera, you usually need a fast shutter. But alternately a flash can be triggered with the scene in the dark and the shutter wide open. It’s this latter technique which PetaPixel are looking at courtesy of the high-speed class at Rochester Institute of Technology. They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons.

Hackaday ☛ Solve: An ESP32-Based Equation Solving Calculator
We’re suckers for good-looking old-school calculators, so this interesting numerical equation-solving calculator by [Peter Balch] caught our attention. Based around the ESP32-WROOM-32 module and an LCD, the build is quite straightforward from an electronics point of view, with the main work being on the software side of things.

Hackaday ☛ Experimenting With MicroPython On The Bus Pirate 5
I recently got one of the new RP2040-based Bus Pirate 5 (BP5), a multi-purpose interface debugging and testing tool. Scanning the various such tools in my toolbox already: an Analog Discovery 2, a new Glasgow Interface Explorer, and a couple of pyboards, I realized they all had a Python or MicroPython user interface. A few people on the BP5 forums had tossed around the idea of MicroPython, and it just so happened that I was experimenting with building beta versions of MicroPython for a RP2350 board at the time. Naturally, I started wondering, “just how hard can it be to get MicroPython running on the BP5?”

Doug Brown ☛ Are wireless gamepads terrible? Mario Maker TAS playback with an RP2040
Earlier this year, there was some drama around the shutdown of the Nintendo Wii U’s online gaming. Team 0% had a goal of making sure that every level created in Super Mario Maker was beaten at least once.

Hackaday ☛ A Phone? A Ham Radio? Relax! It’s Both!
A lot of hams like to carry a VHF radio. Of course, nearly everyone wants to carry a phone. Now, thanks to the kv4p HT, you don’t have to carry both. The open-source device connects to your Android smartphone and turns it into a radio transceiver. You can build it yourself for about $35. Check out the video below.
