This bucket feeder design was motivated by the fact that my wife and I live in different cities and have a cat that hates to ride in the car. The automated feeder makes it possible to be able to leave our cat at one apartment for a weekend without worrying about if she is getting […]

This project is a motion activated redstone lamp. It works by using a crumble microcontroller and an ultrasonic distance sensor wired up to a relay. This project is being entered into the minecraft competition and any votes, favorites or comments would be greatly appreciated! Step 1: Minecraft Redstone Having played Minecraft for quite a long

A 4D printed object is like a 3D printed object, but it changes shape or self-assembles when its environment changes. [Teaching Tech] has been reading about this technology and decided to try to replicate it using his conventional 3D printer. His attempts to make a joint that changes when submerged in the water looked at several

When I saw a COREXY (or H-Bot) plotter, I thought I would make it someday. Since most of its components were made from 3D printers so I have postponed it. Fortunately, once again the PVC pipes gave me an idea to build it with a special version. My Dual-Task CoreXY DrawBot can perform double tasks simultaneously, eg:

Having a 3D printer or a CNC machine available for projects is almost like magic. Designing parts in software and having them appear on the workbench is definitely a luxury. But for a lot of us, these tools aren’t easily available and projects that use them can be out-of-reach. That’s why one of the major

If there’s one thing we’ve learned over the years, it’s that if it’s got a silicon chip inside, it could be carrying a virus. Research by one group focused on hiding a trojan inside an AVR Arduino bootloader, proving even our little hobbyist microcontrollers aren’t safe. The specific aim of the research was to hide a

Flight yokes are key to getting an authentic experience when playing a flight simulator, but [Michel Rechtin] didn’t want to pay big money for a commercially-available solution. He ended up building a design using a lot of parts he had laying around, which saved money and worked out great. The build is based around an Arduino

Although the widespread use of 3D printers has made things like linear bearings and leadscrews more common, you still can’t run down to your local big-box hardware store and get them. However, you can get drawer slides and any hobby shop can sell you some RC servos. That and an Arduino can make a simple and

Sure, we see quite a few plotters and other motion machines, but the one from [DAZ Projects] has the virtual of looking dead simple. The Arduino and CNC shield are old hat, of course. But some 3D printed pulleys and a very simple-looking core XY arrangement looks like this could be a pretty quick build. You might

Here is how to make a Stereolithography 3D Printer. It is still a bit of a work in progress but so far it is working pretty well. This is mainly an experiment which started as a Delta Robot Stereolithography Printer but ended as a more traditional Cartesian Stereolithography Printer. Stereolithography (SL or SLA from Stereolithography
