Not too long ago we announced the Hackaday Meetups. We were hoping at least a few dozen people would be excited to host a meetup in their town. What we got was hundreds of people and we couldn't be ha...

Arduino is the perfect introduction to microcontrollers and electronics. The recent trend of powerful, cheap, ARM-based single board Linux computers is the perfect introduction to computer science, pr...

We posted about a 3D printer fire a while back. An attendee of the Midwest RepRap Fest had left his printer alone only to find its immolated remains on his return. In the spirit of open source, nat…

In the open hardware world, we like to share 3D design files so that our friends and (global) neighbors can use and improve them. But we've all printed things from time to time that we'd like to keep ...

[Anthony Garofalo] has made a fancier plasma speaker. Not content with a simple spark, he uses a plasma vortex. To make the vortex, the spark gap is swapped out for an electrode placed in the centr…

[Stephen B.] kickstarted a MicroPython board. When he got it, he was pleasantly surprised to find that it worked great. His jaded soul balmed with a good experience, he found himself armed with a t…

If you do a lot of one-off parts on your CNC machine you’ll know setup is the worst part of the process. Usually you’re using scrap material, you have to figure out how you’re goi…

From watching a heart valve in operation to meeting your baby before she’s born, ultrasound is one of the most valuable and least invasive imaging tools of modern medicine. You pay for the va…

Bela is a cape for the BeagleBone Black that’s aimed at artists and musicians. Actually, the cape is much less than half of the story — the rest is in some clever software and a real-ti…

Everyone needs a cute robotic buddy, right? [Matthew Hallberg] created WireBeings, an open source 3D printed robotic platform. Looking like a cross between Wall-E and Danbo, WireBeings is designed a...

Ask a hundred people why they like to escape to the forest and you’ll probably get a hundred reasons, but chances are good that more than a few will say they seek the peace and quiet of the w…

The first of the BBC Micro Bits are slowly making their ways into hacker circulation, as is to be expected for any inexpensive educational gadget (see: Raspberry Pi). [Martin] was able to get his hand...

Winner of the third place in last year’s Hackaday Prize was [Chris Low]’s Light Electric Utility Vehicle. In case you think that once a Hackaday Prize is in the bag then that’s it…

[Limpkin] has an idea for a project that uses a lot of IN-9 Nixie tubes. Where a Nixie tube clock would only use four or six tubes, [Limpkin] is looking at fifty IN-9 bar graph Nixie tubes. These tub...

If you watch a lot of TV just after Christmas, you will be familiar with partworks. Or at least, you will if you live in the part of the world this is being written from, and if you aren't you should ...

The device featured here is quite simple, but it's well executed and involves bacon, so what's not to like!

They take their bacon sandwiches seriously in Dundee. And let us tell you, in Scotland th...

A problem faced by all collaborative working spaces as they grow is that of access control. How can you give your membership secure access to the space without the cost and inconvenience of having …

Optical microscopy is over 400 years old, and in that time, it has come a long way. There are many variations of microscopes both in the selection of lenses, lighting, and other tricks to allow an …

A new video has been stirring questions on the internet this week. It shows a test of the Flyboard Air, a device that is somewhere between a Back to the Future Hoverboard and Green Goblin’s g…

If you are a novice electronic constructor, you will become familiar with common electronic components. Resistors, capacitors, transistors, diodes, LEDs, integrated circuits. These are the fodder f…
