2022 Hackaday Prize: Reuse, Recycle, Revamp Finalists

-

The 2022 Hackaday Prize is focused on taking care of the planet. The theme of our second challenge round, “Reduce, Recycle, Revamp” is all about tailoring your projects to make use of existing resources and keeping material out of the landfill rather than contributing to it. Our judges have scrutinized the entries and handed me the sealed envelope. All of these ten projects will receive $500 right now and are eligible for the Grand Prize of $50,000, to be announced in November.

We were looking for two broad types of recycling projects in this round, either projects that incorporate a significant recycled component in their build, or projects that facilitate recycling themselves, and frankly we got a good mix of both!

On the first front, we saw projects that recycled plastic bottles, LCD screens, and the inevitable acrylic off-cuts that result when laser cutting. The X-PC even recycles most of the guts of laptop computers by creating a frame for mounting them as standalone desktops, and the ABN6502 uses scrounged up ICs to make a microcomputer. Skateboard decks made of recycled plastic? We’ll have to test them out, but it’s a cool idea and a great project.

In the machines-for-recycling category, we saw new progress on a neat project, the Plastic Scanner, which aims to build a device that can tell one type of recyclable plastic from another. And apparently the plastic that our 3D printers use is grinding a lot of peoples’ environmental gears, because we had filament re-extruders, filament recyclers, and even a Trash Printer that takes in scrap plastic and directly extrudes it into shape.

You can check out all the finalists in detail, listed in no particular order below. And if you’ve got a project that aims to keep devices out of the landfills by repairing them rather than recycling them, make sure to enter it in the Hack It Back challenge, going on right now.

Our congratulations to all of the finalists!

Modern Radio Receiver Architecture: From Regenerative to Direct Conversion

-

Modern radio receivers have a distinct advantage over the common early designs which I covered in my previous article . Most of the receivers you will have worked with over the past couple decades are designs by Edwin Armstrong ; regenerative, superregenerative, or most commonly superheterodyne. These are distinguished by a few fascinating key traits that bring both benefits and drawbacks. Today let’s dive into Mr. Armstrong’s receivers. I’ll also talk about DC receivers which, despite the name, are not made to listen to batteries. These are receivers you are much more likely to encounter in modern equipment. Regenerative and Superregenerative The regenerative receiver is all about doing more with less. You still see some of these in simple applications like RF remote controls. The idea derives from how an oscillator works. In a simple way of thinking, an oscillator is an amplifier with enough positive feedback that any tiny signal at the right frequency will amplify and then, throu...

Hackaday Links: May 31, 2020

We begin with sad news indeed as we mark the passing of Marcel van Kervinck on Monday. The name might not ring a bell, but his project, the Gigatron TTL computer , certainly will. We did a deep dive on the microprocessor-less computer a while back, and Marcel was a regular at conferences and on the Gigatron forums, supporting users and extending what the computer can do. He was pretty candid about his health issues, and I’ll add that when I approached him a few weeks ago out of the blue about perhaps doing a Hack Chat about Gigatron, he was brutally honest about how little time he had left and that he wouldn’t make it that long. I was blown away by the grace and courage he displayed. His co-conspirator Walter Belger will carry on the Gigatron mission, including joining us for a Hack Chat on June 24. In the meantime, this might be a great time to pick up a Gigatron kit before they’re all sold out and get busy soldering all those delicious through-hole TTL chips. May of 2020 is the mo...

Homebrew 68K Micro-ATX Computer Runs Its Own OS

-

We’re no stranger to home built Motorola 68000 computers here at Hackaday, but more often than not, they tend to be an experiment in retro minimalism. The venerable processor is usually joined by only a handful of components, and there’s an excellent chance they’ll have taken up residence on a piece of perfboard. Then [NotArtyom] sent in his Blitz , and launched the bar into the stratosphere. Make no mistake, the Blitz isn’t just some simple demo of classic chips. The open hardware motherboard has onboard floppy, IDE, and PS/2 interfaces, with a trio of 8-bit ISA expansion slots for good measure. The  Motorola 68030 CPU is humming along at 50 MHz, with 4 MB of RAM and 512 KB of ROM along for the ride. Designed to fit the Micro-ATX motherboard standard, you can even mount the Blitz in a contemporary PC case and run it on a standard ATX power supply. An earlier prototype of the Blitz motherboard. As if the hardware wasn’t impressive enough, [NotArtyom] went ahead and created hi...
