At my university, we were all forced to take a class called Engineering 101. Weirdly, we could take it at any point in our careers at the school. So I put it off for more interesting classes until …

MIT's Computer Science and Artificial Intelligence Laboratory, CSAIL, put out a paper recently about an interesting advance in 3D printing. Naturally, being the computer science and AI lab the paper ...

Like many of us, [Alex] spent a large part of his childhood feeding coin after coin into one arcade game or another. Galaga is one of his all-time favorites, and he has wanted to build a Galaga cab...

Ever wonder why analog TV in North America is so weird from a technical standpoint? [standupmaths] did, so he did a little poking into the history of the universally hated NTSC standard for color t…

If you could only own one piece of test equipment, it should probably be an oscilloscope. Then again, modern scopes often have multiple functions, so maybe that’s not a fair assertion. A case…

ALS robbed one of [C. Niggel]'s relative's of the use of their upper body. This effectively imprisoned them in their house; ALS is bad stuff. Unfortunately too, the loss of upper body mobility meant ...

If you deploy a lot of Raspberry Pi computers, you might find it inconvenient to log into each one to perform different tasks. Orka, an open source project by [Karthik K], is a server that runs on a d...

[Nicomedia] (a team of two) built a payload for their drone with two distinct purposes: to allow it to drop things like rose petals and to fire off fireworks. Honestly, while it is a cool idea, we are...

Today at the Open Hardware Summit in Portland, Alicia Gibb and Michael Weinberg of the Open Source Hardware Association (OSHWA) launched the Open Source Hardware Certification program. It's live, and ...

A fun thread over at the EEVblog forum starts off with [TerraHertz]'s triangle-peg, square-hole capacitor repair job and goes entertainingly down-hill from there.

Everything from horrifying eBay p...

A recurring idea in hackspaces worldwide seems to be that of the vending machine for parts. Need An Arduino, an ESP8266, or a motor controller? No problem, just buy one from the machine!
