Over the last few weeks, our weekly Hack Chats on hackaday.io have gathered a crowd. This week, we're talking about the greatest threat humanity has ever faced: toasters with web browsers.

When my elder brother and I were kids back in the late 1970’s, our hacker Dad showed us this 1960-61 catalog of the Atlas Lighting Co (later Thorn Lighting) with an interesting graphic design on th…

Have you ever wanted to build your own Arduino from scratch? [Pratik Makwana] shares the entire process of designing, building and flashing an Arduino Nano clone. This is not an entry-level project an...

The star turn of most hackspaces and other community workshops is usually a laser cutter. An expensive and fiddly device that it makes much more sense to own collectively than to buy yourself. This…

For quite some time now we’ve seen people casting their own countertops and other surfaces out of cement. It’s a combination of mold-making and surface finishing that produces a smooth …

Building a crystal radio isn't exactly rocket science. Some people who build them go for pushing them technically as far as they can go. Others, like [Billy Cheung], go for style points. The modular r...

Despite what my wife says, I have absolutely no evidence that I snore. After all, I’ve never actually heard me snoring. But I’ll take her word for it that I do, and that it bothers her,…

If you’ve always wanted to see in the dark but haven’t been able to score those perfect Soviet-era military surplus night vision goggles, you may be in luck. Now there’s an open-s…

Wireless power transfer exists right now, but it’s not as cool as Tesla’s Wardenclyffe tower and it’s not as stupid as an OSHA-unapproved ultrasonic power transfer system. Wireles…

A team from Google and CWI Amsterdam just announced it: they produced the first SHA-1 hash collision. The attack required over 9,223,372,036,854,775,808 SHA-1 computations, the equivalent processin…

It was an American ritual for over four decades: wake up early on Saturday morning, prepare a bowl of sugar, and occupy the couch for four glorious hours of cartoons. The only interruptions came wh…

Okay fellow Make-Gyvers, what do you get when you cross a peripheral power cable jumper, a paperclip, springs, and some 3D-printed housings? DIY test lead clips. Test clips are easily acquired, but…

Instructables user [Team_Panic] -- inspired by the resurgence of robot battle arena shows -- wanted to dive in to his local 'bot building club. Being that they fight at the UK ant weight scale with a ...

It's a good thing that a ridiculous pun and a screenprint of Jean-Luc Picard on the bottom of the board is enough to qualify for the 2017 Hackaday Sci-Fi Contest, because [bobricius]'s Python-plus-Ard...

If you are fascinated by stories you read on sites like Hackaday in which people reverse engineer wireless protocols, you may have been tempted to hook up your RTL-SDR stick and have a go for yours…

It’s the year 2260 and you’re being beamed from your starship to the planet below. Being a descendant of present day 3D printers, the transporter prints you out, slowly making one layer…

Sometimes -- despite impracticality, safety, failure, and general good sense -- one has an urge to see a project through for the sake of it. When you're sick of buttering your toast every morning, you...

The year is 2016. Driving home from a day’s work in the engineering office, I am greeted with a sight familiar to any suburban dwelling Australian — hard rubbish. It’s a time when…

Do you like Open Source? Join Hackaday and Tindie at the largest community-run Open Source conference in North America. We'll be at the Southern California Linux Expo next week, and we want to see yo...

There is an old saying: “In theory, theory and practice are the same. In practice, they are not.” We spend our time drawing on paper or a computer screen, perfect wires, ideal resistors…
