Super Chromatic Peril Sensitive Sunglasses

Posted on by

The Joo Janta 200 super-chromatic peril-sensitive sunglasses were developed to help people develop a relaxed attitude to danger. By following the principle of, ‘what you don’t know can’t hurt you,’ these glasses turn completely opaque at the first sign of danger. In turn, this prevents you from seeing anything that might alarm you.

Here we see the beginnings of the Joo Janta hardware empire. For his Hackaday Prize entry, [matt] has created Nope Glasses. Is that meeting running long? Is your parole officer in your face again? Just Nope right out of that with a wave of the hand.

This Is An Inordinate Amount Of Switches

Posted on by

How do you start a good habit? As a blogger, someone who spends a spectacular amount of time on Twitter, and a Thought Leader Life Coach, I can tell you: the best way to start a good habit is by doing it every day. [Arduino Enigma] has just the solution to procrastination, laziness, or whatever else is stopping you from forming a good habit. It’s a good habit tracker, and far too many switches on a single PCB.

The inspiration for this build comes from the master of shitty robots, [Simone Giertz], who built something containing 365 switches and 12 …read more

Turning Tact Switches Into Keyboards

Posted on by

One of the great unsolved problems in the world of DIY electronics is a small keyboard. Building your own QWERTY keyboard is a well-studied and completely solved problem; you need only look at the mechanical keyboard community for evidence of that. For a small keyboard, though, you’d probably be looking at an old Blackberry handset, one of those Bluetooth doohickies, or rolling your own like the fantastic Hackaday Belgrade badge. All of these have shortcomings. You’ll need to find a header for the Blackberry keyboard’s ribbon cable, the standard Bluetooth keyboard requires Bluetooth, and while the Belgrade badge’s keyboard works …read more

Vaporwave For The Parallel Port

Posted on by

FM synthesis is the sound of the 1980s, it’s the sound of shopping malls and Macintosh Plus. It’s the sound of the Motorola DynaTAC, busts of Helios, and the sound of ｖａｐｏｒｗａｖｅ　サ閲ユ. The chips most responsible for this sound is the OPL2 and OPL3, tiny little FM synthesizers on a chip, produced by Yamaha, and the core of the AdLib and Sound Blaster sound cards. It’s the chip behind the music in all those great DOS games.

Unfortunately, computers don’t have ISA slots anymore, and cards don’t work in 486 and Pentium-based laptops, the latest hotness for retrocomputing enthusiasts. …read more

Ask Hackaday: What Is The Future Of Implanted Electronics?

Posted on by

Biohacking is the new frontier. In just a few years, millions of people will have implanted RFID chips under the skin between their thumb and index finger. Already, thousands of people in Sweden have chipped themselves to make their daily lives easier. With a tiny electronic implant, Swedish rail passengers can pay their train ticket, and it goes without saying how convenient opening an RFID lock is without having to pull out your wallet.

That said, embedding RFID chips under the skin has been around for decades; my thirteen-year-old cat has had a chip since he was a kitten. Despite …read more

32 Shades Of Gray

Posted on by

The ATtiny85 is an incredible piece of engineering. In just eight pins, you get a microcontroller with just enough oomph to do some really heavy lifting. You get an Open Source toolchain, and if you’re really good, you can build your own programmer. It does have its limits though; there isn’t a whole lot of Flash, and of course you’re always going to need a few extra pins.

For his Hackaday Prize entry, [danjovic] is pushing whatever limits are left with the ‘tiny85. He’s using it as a test pattern generator, pushing out pixels to any old TV. The entire …read more

Friday Hack Chat: Hacking The Wild

Posted on by

It’s nearly summer, and that means we’re right at the start of conference season, at least for the tech and netsec crowd. Conferences, if you’re not aware, are a conspiracy for the hotel-industrial complex and a terrible way to spend thousands of dollars on a crappy hotel room and twenty-five dollar hamburgers.

[Andrew Quitmeyer] is working on an experimental academic conference that might just put an end to the horrors of conference season. He’s creating his own conference called Dinacon, and it’s going to be cheaper to attend, even though it’s on a tropical island in the Pacific.

For this …read more

Hackaday Links: June 3, 2018

All the Radio Shacks are dead. adioS, or something. But wait, what’s this? There are new Radio Shacks opening. Here’s one in Idaho, and here’s another in Claremore, Oklahoma. This isn’t like the ‘Blockbuster Video in Nome, Alaska’ that clings on by virtue of being so remote; Claremore isn’t that far from Tulsa, and the one in Idaho is in a town with a population of 50,000. Are these corporate stores, or are they the (cool) independent Radio Shacks? Are there component drawers? Anyone want to take a field trip and report?

A few years ago, [cnxsoft] bought a Sonoff …read more

This Is Your Last Chance To Design The Greatest Robotics Modules

Posted on by

It’s Friday, and that means this is your last weekend to get your project together for the Robotics Module Challenge in this year’s Hackaday Prize. We’re looking for tools for robots that blow the doors off what is commercially available. If you have a project in mind that adds sensors or capabilities to our fine electronic friends, enter it in the Hackaday Prize.

The Hackaday community has thrown itself full-force into the Hackaday Prize, and right now we’re getting very close to eight hundred projects entered in this year’s Prize. Next week, we’ll choose the top twenty projects entered during …read more

The Tantillus, Reborn

Posted on by

In the beginning, around 2011 or thereabouts, there was an infinite variety of designs available for anyone to build their own 3D printer. There were Mendels, some weirdos were actually trying to build Darwins, and deltas were starting to become a thing. In the years since then, everyone just started buying cheap Prusa clones and wondering why their house burnt down.

One of the most innovative printers of this era was the Tantillus. It was a small printer, with the entire frame fitting in a 250mm square, but still able to print a 100mm cube. You could print the entire …read more
