[Marco] has a sodium iodide detector that indicates cosmic radiation by scintillation. The material glows when hit by cosmic rays and, traditionally, a photomultiplier tube detects the photos from the …read more Continue reading Raspberry Pi Cosmic Ray Detector
[Markomo] didn’t find much useful information about the Raspberry Pi PIco’s analog to digital converter, so he decided to do some tests to characterize it. Lucky for us, he documented …read more Continue reading Raspberry Pi Pico ADC Characterized
Of course, you’ll want to take your latest 3D design and print it so you’ll have a physical object. But in some cases, you’d like to have a rendering of …read more Continue reading Photorender your 3D Models
If you are a ham radio operator, the idea of sending pictures and data over voice channels is nothing new. Hams have lots of techniques for doing that and — …read more Continue reading Web Pages (and More) via Shortwave
Holograms aren’t new, but a desktop machine that spits them out could be available soon, presuming LitiHolo’s Kickstarter pans out. The machine will have a $1600 retail price and fits …read more Continue reading A Different Kind of 3D Printer: Desktop Holograms
We tend to think of mechanical contrivances as products of the industrial revolution and true automation as something computers handle. Yet even before computers, automation existed — using timing motors …read more Continue reading Historical Hackers: Hero Builds Vending Machines
We wonder if mechanics are as annoyed when we say “engine” as we get when someone talks about a “computer” or a “radio.” Sure, you know what all three of those words mean, but there are many different kinds of …read more
[Bitluni] has been experimenting with resin printing lenses — in particular, lenticular lenses. You’ve probably seen lenticular lenses before in 3D greeting cards or children’s books. By presenting a slightly different image at different angles, your eyes perceive stereo vision …read more

If you’ve used a diode laser engraver or cutter, you know that focus is critical. You’d think it would be relatively simple to get a sharp focus, but it isn’t that simple. [Makers Mashup] shows in a video how to …read more
When we first heard of [Ildar Rakhmatulin’s] plan to use OpenCV on a Raspberry Pi to detect mosquitos and then zap them with a 1 watt laser, we thought it was sort of humorous. However, the paper points out that …read more
