Genezap Improves Your Video Game Skills Using Corporal Punishment

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.

Automated Turret Gives You The Upper Hand In Office Warfare

July 31, 2012 by Mike Nathan 17 Comments

TI-office-turret

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.

Understanding Op-amps From Simple To Hard

July 30, 2012 by Mike Szczys 17 Comments

[Tim] wanted to help out a ECE student struggling with some Op-Amp problems. He put together a video which does a good job of explaining what an Op-Amp does, then tackles each of the questions one at a time.

His analogy is illustrated in this image. There’s an operator using a crane to lift a crate. He is watching a ‘radio man’ in a window of the building to know how high it should be lifted. These roles are translated to the function of an Op-Amp in a way that makes understanding the common parts quite easy. The crane is the Op-Amp and the floor to which it is trying to lift the crate is the input pin. The current height of the crate is the output signal. The radio man is the feedback resistor which is trying to get the desired height and current height to equal each other. Watch the video after the break and all becomes clear.

After this analogy is explained [Tim] tackles the actual homework problems. He’s going through everything pretty quickly, and doesn’t actually give the answers. What he does is show how this — like most circuit solving problems — depends on how you group the components in order to simplify the questions. Grab a pen and paper and put on your electron theory hats to see if you can solve the questions for yourselves.

Building The Most Offensive Video Game Ever

[Autuin] created the most offensive video game ever. Inside a small cocktail arcade cabinet, he installed his own video game that recreates the experiences of the Space Shuttle Challenger and her crew on their last flight.

The build started off by picking up an old cocktail version of Space Zap from The Hackery, a neat little recycling place that turns old computers, monitors, and even old arcade machines into something useful again. After [Autuin] lugged his arcade machine back to his home base at Free Geek Vancouver.

After drooling over the 30-year-old circuitry, [Autuin] disassembled the old machine and installed a mint condition 19″ VGA monitor where an ancient black and white CRT once resided. The control panels replete with their comically large buttons were refurbished and connected to an Arduino and the whole shebang hooked up to a slightly outdated computer.

The real magic happened when [Autuin] coded his game. He created a few sprites from NASA archival footage and made a game where a shuttle takes off and is controllable by each player. As the most offensive video game ever, the space shuttle blows up shortly after launch, declaring ‘game over’ for both players.

[Autuin] will be showing off his new arcade game with a new bezel and cabinet graphics during Vancouver’s Eastside Culture Crawl this November. The game will probably be updated by then; we suggested editing the ‘time to explosion’ to T+73 seconds, but [Autuin] said he’s thinking of ways to make it even more awful.

Excavate Your Basement Using RC Equipment

July 28, 2012 by Jeremy Cook 41 Comments

Although it could be debated as to whether or not this is a “hack,” since the equipment used is built for excavation, the scale of it seems deserving of a mention. In the linked article, [Joe] is quoted as saying, “the common misconception here is that the RC’s are not here to excavate my basement, but rather the basement excavation project is here for the RC’s.” This could be a motto for most makers/hackers in that projects are frequently not done for the resulting product, but for the experience of making something your own.

According to [Joe], he excavates 2 – 3 cubic yards per year with his little RC vehicles. Living in Canada as a rancher and farmer, he’s required to be near his home to feed his hungry animals even during the cold winter months. During this time, there can be very little to do. After sometimes working 16 hour days during the summer, he needed something to keep him occupied close to home. Be sure to check out the excavation video after the break, or check out the original article for even more pictures and video! Continue reading “Excavate Your Basement Using RC Equipment” →

Only You Can Kick A Child’s Balls Into Space

July 27, 2012 by Mike Szczys 26 Comments

We had a lot of fun with that title. Of course when you’re talking about launching a thousand ping pong balls into space there’s no end to the puns which can be made. But this is actually a fantastic initiative to get people of all ages excited about science and near-space experiments. [John Powell] offers school children the opportunity to send an experiment into space. He’s Kickstarting the next launch, which is scheduled to take place in September. This way each entrant can fly their project for free, then get the results and a certificate back once the weather-balloon-based hardware is recovered.

There is one size restriction for the program. Each experiment must fit inside of a ping pong ball. But you’ll be surprised what can be accomplished. [John] reports that the most simple, yet interesting project is to place a small marshmallow inside the ball. As it rises through the atmosphere it will grow to fill the entire ball, then be freeze-dried by the the extreme temperatures. Some are not so low-tech. There’s an image of a tiny PCB holding a DS1337 and some sensors. It’s an atmospheric data logger that will provide plenty of information to analyze upon its return.
