Hacking is about pushing the envelope to discover new and clever ways to use things in ways their original designers never envisioned. [Charlyn Gonda]’s Hackaday Remoticon workshop “Making Glowly Origami” was exactly that; a combination of the art of origami with the one of LEDs. Check out the full course embedded below, and read on for a summary of what you’ll find. Continue reading “Remoticon Video: Making Glowy Origami With Charlyn Gonda”
We’re impressed to see the continued flow of new and interesting ways to utilize 3D printing despite its years in the hacker limelight. At the 2020 Hackaday Remoticon [Billie Ruben] came to us from across the sea to demonstrate how to use 3D printing and fabric, or other flexible materials, to fabricate new and interesting creations. Check out her workshop below, and read on for more detail about what you’ll find.
The workshop is divided into two parts, a hands-on portion where participants execute a fabric print at home on their own printer, and a lecture while the printers whirr away describing ways this technique can be used to produce strong, flexible structures.
The technique described in the hands on portion can be clumsily summarized as “print a few layers, add the flexible material, then resume the printing process”. Of course the actual explanation and discussion of how to know when to insert the material, configure your slicer, and select material is significantly more complex! For the entire process make sure to follow along with [Billie]’s clear instructions in the video.
The lecture portion of the workshop was a whirlwind tour of the ways which embedded materials can be used to enhance your prints. The most glamourous examples might be printing scales, spikes, and other accoutrement for cosplay, but beyond that it has a variety of other uses both practical and fashionable. Embedded fabric can add composite strength to large structural elements, durable flexibility to a living hinge, or a substrate for new kinds of jewelry. [Billie] has deep experience in this realm and she brings it to bear in a comprehensive exposition of the possibilities. We’re looking forward to seeing a flurry of new composite prints!
When you want to quickly pull together a combination of media and user interaction, looking to some building blocks for the heavy lifting can be a lifesaver. That’s the idea behind Max, a graphical programming language that’s gained a loyal following among anyone building art installations, technology demos (think children’s museum), and user Kiosks.
Guy Dupont gets us up to speed with a how to get started with Max workshop that was held during the 2020 Hackaday Remoticon. His crash course goes through the basics of the program, and provides a set of sixteen demos that you can play with to get your feet under you. As he puts it, if you need sound, video, images, buttons, knobs, sensors, and Internet data for both input and output, then Max is worth a look. Video of the workshop can be found below.

Modular synthesizers, with their profusion of knobs and switches and their seemingly insatiable appetite for patch cables, are wonderful examples of over-complexity — the best kind of complexity, in our view. Play with a synthesizer long enough and you start thinking that any kind of sound is possible, limited only by your imagination in hooking up the various oscillators, filters, and envelope generators. And the aforementioned patch cables, of course, which are always in short supply.
Luckily, though, patch cables and the modules they connect can be virtualized, and in his 2020 Remoticon workshop, Jonathan Foote showed us all the ways VCV Rack can emulate modular synthesizers right on your computer’s desktop. The workshop focused on VCV Rack, where Eurorack-style synthesizer modules are graphically presented in a configurable rack and patched together just like physical synth modules would be.

It’s a ritual in workplaces around the world this time of any other year but 2020: the office holiday party. Too much food, perhaps too much alcohol, and garish sweaters that you wouldn’t be caught dead in on any other occasion. Things are, of course, a tad different this year, which is why we’re putting our community’s party online with the Holiday with Hackaday and Tindie meet-up on Tuesday, December 15 at noon Pacific time!
Why should you come to this hangout? Because why not! This is going to be a loose, informal meet-up that will give us all a chance to get to know one another. We’ve got an amazing community here, and just putting faces to names can be really valuable. You’ll be able to connect with old friends and perhaps make new ones. It’s your chance to reach out and find someone to collaborate with, or perhaps just find an answer to a thorny problem you’ve been stuck on. Be sure to bring your latest projects to show off, and maybe even consider giving everyone a virtual tour of your shop. Ugly sweaters are optional, of course, and we don’t judge.
The Holiday with Hackaday and Tindie meet-up is being held on Remo. Those of you who joined the Friday night Bring-a-Hack session at Remoticon this year will no doubt remember the platform, which we got a lot of good feedback on. You’ll want to check browser compatibility ahead of time and reserve your spot, so head over to Remo and make it so. If you need help with timezone conversions, we’ve got you covered on that too.
We’re looking forward to seeing everyone at the Holiday with Hackaday and Tindie meet-up!
If only you could get your hands on the code to fix the broken features on your beloved electronic widget. But wait, hardware hackers have the skills to write their own firmware… as long as we can get the compiled binary into a format the hardware needs.
Luckily, we have Uri Shaked to walk us through that process. This workshop from the 2020 Hackaday Remoticon demonstrates how to decipher the encryption scheme used on the firmware binary of a 3D printer. Along the way, we learn about the tools and techniques that are useful for many encrypted binary deciphering adventures.

There was a time not too long ago when hacking a car more often than not involved literal hacking. Sheet metal was cut, engine cylinders were bored, and crankshafts were machined to increase piston travel. It was all in the pursuit of milking the last ounce performance out of every drop of gasoline, along with a little personal expression in the form of paint and chrome.
While it’s still possible — and encouraged — to hack cars thus, the inclusion of engine control units and other systems to our rides has created an entirely different universe of car hacking options, which Amith Reddy distilled into his very popular workshop at the 2020 Remoticon. The secret sauce behind all the hacks you can accomplish in today’s drive-by-wire cars is the Controller Area Network (CAN), the network used to connect the array of sensors, actuators, and controllers that lie under the metal and plastic of modern cars.
