Mimicking Exoplanet Exploration At Home

Mankind will always wonder whether we’re alone in the universe. What is out there? Sure, these past weeks we’ve been increasingly wondering the same about our own, direct proximity, but that’s a different story. Up until two years ago, we had the Kepler space telescope aiding us in our quest …read more

DMCA Takedown Issued Over Casio Code That Wasn’t

Earlier this month, we posted coverage of an ingenious calculator hack that took a Casio calculator and put an ESP8266 module and an OLED display in the space occupied by its solar cell. Controlled by a pair of unobtrusive Hall effect devices, the calculator could have been used as an …read more

Matrix of Resistors Forms the Hot Hands Behind This Thermochromic Analog Clock

If you’re going to ditch work, you might as well go big. A 1,024-pixel thermochromic analog clock is probably on the high side of what most people would try, but apparently [Daniel Valuch] really didn’t want to go to work that day.

The idea here is simple: heat up a …read more

Flexible PCB Earrings Put the Art in Art Deco

Earrings have been a hackers’ target for electronic attachment for quite a while, but combining the needed components into a package small enough to wear in that finicky location is quite a challenge. If [Sawaiz Syed]’s Art Deco Earrings are anything to go by, ear computers have a bright …read more

Conduit, Birdhouse, and Skateboard Become Giant Pen Plotter

If you think you need fancy parts to build a giant robot drawing machine, think again! [Cory Collins] shows you how he built his Big-Ass Wall Plotter v.2 out of stuff around the house or the hardware store, including electrical conduit, gang boxes, scrap wood, and skateboard bearings, alongside the …read more

Resistors Sorter Measures Values

We’ve all been there. A big bag of resistors all mixed up. Maybe you bought them cheap. Maybe your neatly organized drawers spilled. Of course, you can excruciatingly read the color codes one by one. Or use a meter. But either way, it is a tedious job. [Ishann’s] solution was …read more
