New App Note Day: Internet of Pillows

Posted on by

The Internet of Things is a cancer that consumes all reasonable expectations of technology, opens vast security holes we’ve never had to deal with before, and complicates life in the pursuit of quarterly gains from whatever technology startup is hot right now. We are getting some interesting tech out of it, though. The latest in the current round of ‘I can’t believe someone would build that’ is the Internet of Pillows. No, it’s not a product, it’s just an application note, but it does allow us to laugh at the Internet of Things while simultaneously learning about some really cool …read more

You Can Build Anything Out Of What Is Holding Your 97 Eagle Talon Together

Posted on by

We all know it, we all love it, and the guy parked outside of the 7-11 covered his car in it. What is it? Polyester body filler, better known by the almost generic trademark, Bondo. There’s a lot more you can do with Bondo than fairing in that sweet body kit, bro, and [Eric Strebel] is here to show you how far you can push the mechanical properties of polyester body filler.

We didn’t always have polyester body filler. In the days before OSHA, auto body workers would use a torch, bricks of lead, and a grinder. You can check …read more

The Better RetroPie Handheld

Posted on by

The Raspberry Pi has become the best video game console on the planet. With RetroPi, anyone can play Super Mario 3, Doctor Mario, and even Doki Doki Panic. Adafruit’s PiGRRL Zero and [Wermy]’s reconfabulation of an old brick Game Boy to house a Raspi Zero and display have made the Raspberry Pi portable, along with all those retro games we love so dearly.

There’s a problem with these builds, though. They only use the Raspberry Pi Zero, and with that the limitations on emulation performance, and the Raspi 3 is far too big for a portable console. What’s the solution? …read more

Because Building A Relay Computer Isn’t Hard Enough

Posted on by

For this year’s Hackaday Prize, we’re doing something special. We’re introducing achievements for Prize projects. Think of them as merit badges. If your Hackaday Prize project has multiple parts that come together into one unified, awesome whole, you get the Voltron achievement. If you’ve built a musical instrument that unexpectedly blows everyone’s minds, you get the Diva Plavalaguna Achievement. A select few entries will earn the Pickle Rick achievement. What’s this? It’s a jaw-dropping build that makes you shake your head in the totality of engineering perfection.

Here’s a project that nails this achievement. It’s a homebrew computer, made out …read more

The Amazing Hacks Of World Create Day

Posted on by

For this year’s Hackaday Prize, we started an amazing experiment. World Create Day organized hundreds of hackerspaces around the world to come together and Build Hope for the future. This was an experiment to bring community shops and workspaces together to prototype their entries for the Hackaday Prize, and boy was it a success. We had hackerspaces from Portland to Pakistan taking part, and these are just a few of the amazing hacks they pulled off.

Detoured: RF And Film

Posted on by

The technology behind capturing aerial video is so unbearably cool. Not only do you have fancy cameras that cost as much as a car, you also have remote control camera mounts on helicopters and amazing microwave links going to the ground. This isn’t your typical FPV setup on a quadcopter; there are jet turbines and S-band transmitters here.

One of the people behind these amazing aerial shots is [Greg Johnson] of RF Film based out of Whiteman airport in sunny southern California. He’s done work for Black Panther, several fo the Fast & Furious films, Marvel movies, and is working …read more

Hackaday Links: Some Sort Of Fool’s Day, 2018

Posted on by

A few years ago, writing for a blog called Motherboard of all things, [Emanuel Maiberg] wrote PC Gaming Is Still Way Too Hard. The premise is that custom building a gaming PC is too hard, because you have to source components and comparison shop. Again, this was written for Motherboard. Personally, I would have shopped that story around a bit more. Now, the same author is back again, telling us PC Building Simulator is way more fun than building a real computer. It’s my early nomination for worst tech article of the year.

Speaking of motherboards, This is a …read more

Autodesk Introduces Serpentine Router For Eagle

Posted on by

Since Autodesk acquired Eagle a few years ago, they’ve been throwing out all the stops. There is now a button in Eagle that flips your board from the front to the back — a feature that should have been there twenty years ago. There’s parametric part generation, push and shove routing, integration with Fusion 360, and a host of other features that makes Eagle one of the best PCB layout tools available.

Today, Autodesk is introducing something revolutionary. The latest version of Eagle (version 8.7.1) comes with a manual serpentine routing mode, giving anyone the same tools as the geniuses …read more

A High Speed, Infinite Volume 3D Printer

Posted on by

One of the most interesting developments in 3D printing in recent memory is the infinite build volume printer. Instead of a static bed, this type of printer uses a conveyor belt and a hotend set at an angle to produce parts that can be infinitely long in one axis, provided you have the plastic and electricity. For this year’s Hackaday Prize, [inven2main] is exploring the infinite build volume design, but putting a new spin on it. This is a printer with a conveyor belt and a SCARA arm. The goal of this project is to build a printer with a …read more

Emulating A Complete Commodore 64

Posted on by

When the Commodore 64 was released in 1982, it was a masterpiece of engineering. It had capabilities far outstripping other home computers, and that was all due to two fancy chips inside the C64. The VIC-II, the video chip for the C64, had sprites and scrolling, all stuffed into a single bit of silicon. The SID chip was a complete synthesizer on a chip. These bits of silicon made the C64 the best selling computer of all time, but have also stymied efforts to emulate a complete C64 system on a microcontroller.

[Frank Bösing] has just managed to emulate an …read more
