Take a minute to think about what your dream job might be.
Done imagining you are a ridiculously wealthy bachelor? Good.
Back here in the real world, [Caleb Cover] has come into what might be one of the coolest hacking-related jobs we’ve seen in awhile. He recently snagged a gig working for Aleph Objects as the fleet master for a large array of 3D printers. His duties include the care and feeding of 30 MiniMax-style repraps, a job description we sure wouldn’t mind having.
Aside from merely gloating about his newfound employment, [Caleb] wrote in asking if we knew of a reprap setup larger than the one he is responsible for. We couldn’t come up with one, but perhaps you can.
Right now, [Caleb] says that he’s working on seeing how well the machines can produce parts to replicate themselves, which will certainly make this the largest collective set of production 3D printers sooner or later.
While you hunt down other large reprap setups at your monotonous desk job, check out the video below to hear the symphony of 3D printing that greets [Caleb] at the door each day.
Think you might have seen a 3D printing setup more massive than this one?
Pics Vids or it didn’t happen. Seriously, we want to see em!

[Steve] is often host to all sorts of guests, and he was looking for an easy way to let his friends come and go as they please. After discovering that his front door came equipped with an electronic strike, he decided that an RFID reader would be a great means of controlling who was let in, and when.
Giving all your friends RFID cards and actually expecting that they carry them is a bit of a stretch, but lucky for [Steve] he lives near Boston, so the MBTA has him covered. Just about everyone in town has an RFID subway pass, which pretty much guarantees that [Steve’s] cohorts will be carrying one when they swing by.
He crafted a stylish set of wooden boxes to contain both the RFID reader and the Arduino that controls the system, matching them to the Victorian styling of his home. A single button can control the setup, allowing him to add and remove cards from access lists without much fuss. For more granular control however, [Steve] can always tweak settings from the Arduino serial console.
The card system is both stylish and useful – a combination that’s hard to beat.
Ahh, the Lite Brite.
What could be more fun than pushing dozens of little plastic pegs through a piece of black paper in order to create a pixelated, though colorful image? Well, I can think of quite a few things more engaging than that, and luckily so can [Lonnie Honeycutt] over at MeanPC.
While contemplating what to build with a pile of LEDs, his daughter came into the room with her portable Lite Brite. He thought that the pegs she was using looked awfully similar to the LEDs on his desk, so he did some test fitting and was surprised to see that they fit almost perfectly.
[Lonnie] thought that the toy would make an excellent clock, and his daughter happily agreed to let Dad do some tinkering. A few hours, an Arduino, and some Charlieplexing later, he had a nice looking clock that his kids were sure to enjoy.
If you’re interested in seeing more about how constructed, be sure to check out his YouTube channel and Instructable, where he happily provides all of the build details.
It seems like [Chris Downing] is always up to something new. If he’s not keeping busy by creating slick portable iterations of previous-gen gaming consoles, he is dreaming up ways to make his modding life a bit easier.
Recently while working on a Nintendo controller designed to control three different consoles, [Downing] found his desk buried in a pile of power supply and A/V cabling. Annoyed with his growing rat’s nest, he decided to build a universal power supply that would allow him to quickly switch between consoles with little effort.
He dug up an old PC power supply, and fed it into a LED control box built for cars. [Downing] then mounted an array of nine rocker switches on the box, adding A/V inputs and outputs along the way. A set of voltage regulators hidden inside allow [Downing] to dial in whatever custom voltages he might need at the moment.
The test box should come in pretty handy as [Downing] pursues even more modding projects in the months to come. In the meantime, be sure to check out the video below where he covers the finer points of the device’s design.

As if getting your ass handed to you while playing video games wasn’t annoying enough, [furrtek] decided that the best way to help improve his skills was by inflicting physical pain each time his on-screen character died.
While perusing the Internet looking for something to break through the doldrums of the day, he came upon a video in which someone decided to try on a dog shock collar just for kicks. This sparked [furrtek’s] imagination, and he started to think that it would be pretty cool to use the same sort of device to make dying in a video game that much more unpleasant.
After ordering a set of collars online, he tore them apart to see how they functioned, and to measure just how big of a jolt they were able to deliver. [furrtek] then modified two Genesis controllers with a pair of ATtiny 25s, which let him send the fire signal to the collars. Unfortunately, stock Genesis games don’t allow you to send signals to the controllers, so [furrtek] had to spend some time hacking ROM images to trigger events when players are injured or lose a life.
We think the project is pretty slick, and if you don’t mind fiddling with your old controllers, you too can have a merciless trainer strapped around your neck. For those slightly more averse to pain, you can watch [furrtek] and his friend [Dyak] suffer the consequences of poor gameplay for your amusement.

Fans of vintage Apple ][ and TRS-80 games will undoubtedly recognize the image above in short order. Taipan! was a popular game in its time, and [Simon] decided it was a great title to try recreating with an Arduino.
His goal was to use a standard Arduino Duemilanove to reproduce the game, rather than opting for a Mega or something like the Raspberry Pi. Seeing those two options as “too easy”, he ventured into the project with some self-imposed limitations, making it a more fruitful adventure.
In the end, [Simon] had to use two Arduinos – one to control the gameplay and another to run the display. Simon tucked both boards, a keypad, and an LCD screen inside a first run copy of Tai-Pan, a move that is sure to please Apple aficionados and Xzibit fans alike.
[Simon] made sure that no detail was overlooked during the port, making sure to include every line of text as well as every bug found in the original game.
Check out a video of the finished project below, and be sure to swing by his site for a very thorough build log.

When your co-workers get on your nerves, the mature recourse is to be the bigger person and simply ignore the obnoxious individual. A team of engineers from TI show us a slightly alternative means of dealing with office mates which is not quite as mature, though far more entertaining.
The office toy cum mechanized weapons system relies on a TI MSP430 LaunchPad, coupled with a custom Turret430 breakout board. The former is the brains of the operation, while the latter houses motor drivers for the motorized turret. The system can be steered throughout its 300 degree range of rotation using an attached joystick, but in the interest of catching their target by surprise, they added an automated mode as well. The automated targeting system uses an attached webcam to pick out victims by the color of their clothing, which seems to work pretty well.
To see the system in action, check out the video embedded below.
