Syringe Pump Turns CNC Machine Into A Frosting Bot

“Amazing how with only the power of 3D-printing, two different computers, hundreds of dollars in CNC machinery, a lathe, and modern microcontroller magic, I can almost decorate a cupcake as well as a hyperactive ten-year-old.”  We can think of no better way to sum up [Justin]’s experiment in CNC frosting …read more

Fish Hooks Embedded in Robot Toes Make Them Climb Like Cockroaches

Take a dozen or so fish hooks, progressively embed them in plastic with a 3D printer and attach them to the feet of your hexapod and you’ve got a giant cockroach!

A team of researchers at Carnagie Mellon University came up with this ingenious hack which can easily be copied …read more

Yo Dawg, I Heard You Like FPGAs

When the only tool you have is a hammer, all problems look like nails. And if your goal is to emulate the behavior of an FPGA but your only tools are FPGAs, then your nail-and-hammer issue starts getting a little bit interesting. That’s at least what a group of students …read more

Scripting Language Rapidly Develops A Clock

In the past, you might very well have started programming in Basic. It wasn’t very powerful language and it was difficult to build big projects with, but it was simple to learn, easy to use, and the interpreter made it easy to try things out without a big investment of …read more

Magnetic Attraction Of Microduino mCookie Modules

We’ve seen countless different robot kits promoted for STEM education, every one of which can perform the robotic “Hello World” task of line following. Many were in attendance at Maker Faire Bay Area 2019 toiling in their endless loops. Walking past one such display by Microduino, Inc. our attention was …read more

Nuclear Reactor Simulator Is The Project Of A Lifetime

Have you been watching Chernobyl? Well, so has everyone else. Right now it seems the whole Internet is comprised of armchair dosimetrists counting roentgens in their sleep, but [Mark Wright] doesn’t need a high-budget TV show to tell him about the challenges of wrangling the atom with 1980s technology. …read more

Custom Machined Pump Keeps CNC Lubrication Under Control

Rub two pieces of metal against each other hard enough, and it won’t be long before they heat up sufficiently to cause problems. That’s especially true when one is a workpiece and one is a tool edge, and the problems that arise from failing to manage the heat produced by …read more

LED Matrix Becomes Fun Tetris Clock

Sometimes a project is borne simply out of the fact that some interesting parts have been left sitting around too long. Of course, this is as good a reason to build as any other, and can often lead to some interesting results. [Jorj Bauer]’s Tetris Display is one such project. …read more

Smart Bike Helmet Is Wireless

If you ride a bike, you probably share the road with a lot of cars. Unfortunately, they don’t always share the road very well with you. [Mech Tools] took a helmet, a few Arduinos, and some wireless transceivers and made headgear that shows when you stop and also shows turn …read more
