Here's Brian Egenriether's new-and-improved Skittles sorting machine. It's interesting to note that he used machinable epoxy for the parts instead of using a 3D printer. I know 3D printing is the future, but the current crop of home 3D printers make ugly parts. Subtractive fabrication technology makes better looking stuff, at least for now.
This machine sorts Skittles, m&m's and similar candies by color. It is the 3rd revision of the original machine. The inside is now complete and features user-selectable inputs to choose which type of candy to sort. Types not shown include Reese's Pieces and other types of Skittles.
The microcontroller is a BASIC Stamp 2 and the color sensor is made by TAOS. I made most of the parts by hand from a machinable epoxy including the outer case, inner housing, hopper mechanism, 5 way chute, and the the rotating disk inside. The other parts include a piece of PVC, ceramic bowls, telescope parts, wood for the base, and the funnel which was cut from a hummingbird feeder.

I’d not heard of Elektor magazine until today, when I came across this photo of the cover from a 1974 edition. I assumed it was fake. Everything about it seemed like it was created this year – the typeface, the names of the projects, the tagline (“up-to-date electronics for lab and leisure”). Someone has uploaded […]
Most of us need a computer interface implanted in our brains like we need a hole in our head. That said, there are benefits to bridging the gap between mind and machine. Joel Murphy is the founder of OpenBCI, an inexpensive, and non-invasive, brain-computer interface (BCI) platform. People have used OpenBCI to control robots, compose […]
Last week Carla posted Scotty’s amazing video about building an iPhone from scratch. Scotty just sent me a couple of photos that show just how difficult it was to build the phone: The attached photos are from one of the booths that sells screws and brackets and other accessories for repairing and refurbishing iPhones. The […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
