[John De Cristofaro aka Johngineer] uses various ATmega microcontrollers in his electronics projects, but he finds himself reaching for an ATtiny2313 or ATtiny4313 more often than not. He got tired of having to wire up pin headers, capacitors, and the like each time he started a project, so he spent some time designing an easy [...]

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 [...]

[Ray's] breadboard power supply lets you drain the last traces of power from ‘dead’ AA batteries. Electronics that are powered off of disposable alkaline batteries have a cutoff voltage that usually leaves a fair amount of potential within. Since many municipal recycling programs don’t take the disposables (you’re just supposed to throw them in the [...]

[Claudio] was working on a homebrew oscilloscope project when he started thinking about how unsuitable a standard breadboard is for a large-scale project. Rather than adding components on top of components until they became what he lovingly calls a “fragile, unforgiving crapstack”, he decided to build himself the Ultimate Breadboard. He packed so much into [...]

[Chris] has been hard at work building his own version of Simon called [Nomis]. Although [HAD] has featured an ATiny Simon clone before, the article does an excellent job explaining how the system works. The ATTiny85 is used to control this game, which, for now is laid out on a simple breadboard. A PCB version [...]

[Irongeek] is up to his old tricks once again with this new key logger prototype. It’s in the early stages, as attested by the breadboard built circuit, but [Adrian] still gives us a demo video after the break showing where he’s at right now. It comes in two flavors, the USB pass through seen above, [...]

[Rajendra] got tired of building the same basic circuits time and again on the breadboard. He decided to build some simple, modular circuits on protoboard and make them easy to interface with the breadboard. As you can see, he ended up with seven modules that make prototyping faster and easier. At first glance some might [...]

If you like messing around with electronics, one of the best tools you can have on hand is a solderless breaboard. These handy little chunks of plastic just let you “plug n play” so you can quickly develop a circuit before committing it to solder and fiberglass. Handy as they are, they do have their [...]

Although not everyone has the ability to make a hacked Pong game Like [Marcelo], even fewer have the ability or the creativity to come up with the elaborate hack that he did. The basic premise of his game is a version of pong played on a breadboard with a 8×8 matrix of LEDs. The controls [...]

[Quinn Dunki] got tired of messing around with wires when connecting things to her benchtop power supply, so she built herself useful little power bridge that plugs directly into any standard breadboard. The board is small and simple, but quite useful all the same. It was built to power both sides of the breadboard, and [...]

[Ray] likes to build all sorts of Propeller-based projects, but one of the more interesting items we came across was this DIY ECG. While we have covered other DIY electrocardiograms before, he left the breadboard behind and put together a nicely done PCB for his build. The ECGs design should be pretty familiar to anyone [...]

For those less experienced folks looking to move their Arduino projects to more permanent installations, this is just for you! [Martyn] Posted a three part series, VeroBoardUino, over at his blog about moving your Arduino project to a soldered breadboard. Part one kicks off with the appropriate breadboard requirements, modifications, and a simple 7805 power [...]

[Ben Laskowski's] been working on a Class-D audio amplifier for several months. What you see above is the most recent version of the amp. A class-D amplifier uses transistor switching (or in this case MOSFET switching) to generate the pulse-width-modulated signal that drives the speaker. This is different from common amplifiers as it doesn’t generate [...]

[Oneironaut] is trying out a new GPS module with the prototype seen above. It’s a San Jose Navigation device identified as FV-M8 and sold by Sparkfun for just under a hundred bucks. That’s it hanging off the bottom-right of the breadboard seen above. They’ve packed a lot of power into the small footprint, and made [...]

AVR chips are convenient because you can program them in circuit at their operating voltage. That is, unless you screw up the fuse settings and they’ll no longer listen to an In System Programmer. If you find yourself facing this problem, just build this circuit on a breadboard and ‘unbrick’ by holding down the button. [...]

Inspired by a project featured here on Hack-a-Day, [arthurb] bought himself a PIC 24F and started experimenting once he learned the ins and outs of programming the chip. Using a breadboard and a nest of wires was fine for his first few projects, but as he advanced, he began to feel the need for a [...]

In the last installment of our tutorial series we built a simple circuit on a breadboard and programmed an ATmega168 to make it run. That proves that you know how to follow directions, but the eureka moments of doing everything yourself are on the way. This time around you will get down and dirty with [...]

Lazarus-64, breadboard game system; certainly sounds like something from the 1980s. We were surprised to find out not only the name, but also all the ICs used are only those available from the retro age of 30 years back (Save for the AVR controlling everything, of course). Even more amazing is how it has 256 [...]

[Riley Porter] has been working on several different custom enclosure designs. Above, you can see his Proto Desk which holds a breadboard, Arduino, and has two recessed boxes with sliding tops for components and patch wires. He’s got a miniature version that gets rid of the breadboard, as well as slick-looking cases for the Bus [...]
