Here’s a great picture from [Jelly & Marshmallows] that shows off the wild effects of melted chocolate poured onto a diffraction grating. A diffraction grating is a kind of optical …read more Continue reading Iridescent Rainbow Chocolate, Just Add Diffraction Grating!
[Ramin assadollahi] has been busy rebuilding and improving an Omnibot 5402, and the last piece of hardware he wanted to upgrade was some LED matrix eyes and a high quality …read more Continue reading Omnibot From the 80s Gets LED Matrix Eyes, Camera
One thing about vintage computers is that they depend greatly on whether or not one can plug a compatible monitor into them. That’s what’s behind [Tube Time]’s Graphics Gremlin, a …read more Continue reading Retro ISA Card Means Old, Slow Computers No Longer Need Old, Heavy Monitors
In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it …read more Continue reading Soil Moisture Sensors, How Do They Work?
Desiccant is common in 3D printing because the drier plastic filament is, the better it prints. Beads of silica gel are great for controlling humidity, but finding a porous container …read more Continue reading 3D-Printed Desiccant Container Exploits Infill
One way to play with vintage hardware without owning the hardware is to use an emulator, but [omni_shaNker] announced taking it to the next level by using VR to deliver …read more Continue reading Commodore 64 Emulator in VR Delivers a Full 80s Experience
The ATMegaZero ESP32-S2 is currently being funded with a campaign on GroupGets, and it’s a microcontroller board modeled after the Raspberry Pi Zero’s form factor. That means instead of the …read more Continue reading Looks Like a Pi Zero, Is Actually an ESP32 Development Board
With little more than four economical stepper motors, a Raspberry Pi Zero, and a 3D printer, [Thomas Barlow] made himself an awfully slick Smart Flip Clock that can display not …read more Continue reading This DIY Split-Flap Display Does Both Time and Weather
Like the looks of stained glass, but not the amount of work, skill, and materials involved? Well, [Northern Geometry] shows how to sidestep all that nonsense and use a 3D …read more Continue reading Faux Stained Glass Effect, With 3D Printing and Epoxy
3D scanning and 3D printing may sound like a natural match for one another, but they don’t always play together as easily and nicely as one would hope. I’ll explain …read more Continue reading What to Expect From 3D Scanning, And How To Work With It
