A conventional compass points north (well, to magnetic north, anyway). [Videoschmideo]  wanted to make a compass that pointed somewhere specific. In particular, the compass — a wedding gift &…

If you have a laser printer, you’ve got your Christmas presents sorted out. At least if your family likes jigsaw puzzles. The idea is very simple, laminate a photograph onto some laser-cuttab…

Rendering something in slow-motion is an often-used technique that attempts to add some 'wow' or 'cool' factor. Seeing something out in the world move in slow motion is marginally rarer -- rarer still...

We got quite a few tips in about a paper from Vanderbilt about a cool scrap metal battery they’ve been playing with. They made some pretty bold claims and when we fed the numbers in they pret…

Tiny laptops have always been devices that promise so much, yet fail somehow to deliver. From the Atari Portfolio palmtops through to the recent crop of netbooks they have been either eye-wateringl…

Most programming languages today look fairly similar. There's small differences, of course (Python using spaces, Ruby and Perl have some odd-looking constructs). In the 1960s and 1970s, though, a lot ...

Dtto, a modular robot designed with search and rescue in mind, has just been named the winner of the 2016 Hackaday Prize. In addition to the prestige of the award, Dtto will receive the grand prize o...

Need additional, custom IO for your Raspberry Pi? Adding an FPGA is a logical way to expand your IO, and allow for high speed digital interfaces. [Eric Brombaugh]'s Icehat adds a Lattice iCE5LP4K-SG...

There’s something to be said for whizzing around town on your own automatic personal transport. It’s even better when you’ve built it yourself. That’s just what [The Raspber…
