[Dino's] kitchen skills match his hardware hacking prowess. Look really close at the image above and you’ll realize this collection of transistors and passive components is edible. Rather than decorating cookies for the holidays he built this audio amplifier from gingerbread, icing, and candy. The thing is, [Dino] almost always has that extra touch to [...]

There are a ton of benefits for etching your own circuit boards at home, chief among them the ability to design a circuit in the morning and have a prototype in your hand by lunch. There’s always the question of how to etch the board, but [NurdRage] over on Youtube has all the chemistry covered on [...]

Way back when [Ms Ellsworth] was a kid, she kept seeing the same circuit over and over again in her various op-amp books. It was a Wien bridge oscillator, a small circuit that outputs a sine wave with the help of a light bulb. Now that [Jeri] is much wiser, she decided to play around [...]

If you’re like a lot of people, most of the time your computer speakers are on without actually playing any music. This wastes a bit of power, and [Bogdan] thought he could create a circuit to cut down on that wasted electricity. The result is a very tiny auto-on circuit able fit inside a pair [...]

tormux.rb is a single file, zero dependency ruby tor controller for reverse multiplexing outgoing connections between tor exit nodes. By default tor only builds a single circuit, and all your traffic will travel out of a single exit node until the circuit is destroyed and a new circuit is created. but tormux.rb will build and maintain one circuit for each of the number of exit nodes you specify, and round robin your outgoing tor connections between them automatically.

When [Phil Burgess] showed off a few I2C – controlled seven-segment displays on adafruit’s weekly vlog, the comments immediately turned to the time circuits featured in everyone’s second-favorite time machine, the Back to the Future DeLorean.

The thought of using a 3D printer to fabricate PCBs is tantalizing and the good news is that it’s a reality. This project shows that it’s possible to use a special printer head to apply traces to an extruded substrate. This is similar to the point-to-point 3D printer circuits with one big upgrade. Now the traces [...]

[CarryTheWhat] put up an Instructable on his endeavours in printing circuit boards for solder free electronics. He managed to print a flashlight where the only non-printed parts are a pair of batteries and a couple of LEDs. The circuit is a weird mix of point to point and Manhattan style circuit construction; after modeling a printed plastic plate, [CarryTheWhat] added [...]

Chaos Communication Congress 27th (27C3) 2010 Abstract: Are you ready to wake up from the cult of Arduino? Tired of plugging together black-box pre-built modules like a mindless drone, copying and pasting in code you found on Hackaday? You've soldered together your TV-Be-Gone, built your fifth Minty Boost, and your bench is awash with discarded Adafruit packaging and Make magazines. It's time to stop this passive consumption. It's time to create something that is truly yours. It's time, my friend, to design your first circuit board. And you'll need a machine to print it. Outsourcing printed circuit board (PCB) manufacture can be expensive and slow. You want your board now, for free. And designing PCB's is hard. You'll make mistakes, and some boards will be wasted. You can etch your own PCB's at home but the process is fiddly, and notoriously difficult to perfect. What if you had a printer that could make PCB's? A rapid prototyping machine for circuit boards. In this talk I will present my progress towards an inexpensive PCB printer by reverse engineering Epson inkjet technology. And I'm not talking about the crappy print-and-bake method you might have seen on the internet. Come and learn about the miracle of microfluidics within the modern consumer inkjet printer, and how to push it to do new, exciting things. I'll be describing some reverse engineering techniques, a bit of electronics circuit design and the potential for 3D microfabrication with inkjet technology. A PCB will be printed and etched live, on stage, at 27C3!

The look of this crystal clear resin brick is pretty amazing. [Rupert Hirst] decided to encase his amplifier circuit in a block of polyester resin. We just hope he got everything in his circuit right because there’s no way to replace any of those parts now! He deserves a lot of credit for working out [...]

Some of the pinball machines which [Jeri Ellsworth] has restored have ended up in the break room at her work. We’re sure her coworkers are thankful for this, but sometimes they forget to turn off the power to the machines, and letting them run constantly means more frequent servicing will be necessary. She set out [...]

Here’s another circuit that can be used to squeeze the remaining potential from supposedly dead batteries. Just like the AASaver, we see this as a useful prototyping tool, providing juice for a breadboard even though it’s not reliable enough for long-term use (the batteries are just about through after all). First off, the image above [...]

As far as battery technology goes, Lithium Polymer cells are the bee’s knees. They’re powerful enough to handle very demanding applications and come in a multitude of sizes for any conceivable application. There’s a problem with LiPos, though – they have the tendency to explode when charged incorrectly. Luckily, [Paul] sent in a great tutorial on [...]
