Here’s a fun game from [A.J.]’s lab. It’s a simulated king cobra made from an Arduino, an ultrasonic sensor, and a servo. The aim of the game is to grab a ball in front of the device without being ‘bitten’ by the thumbtack attached to a drinking straw controlled by a servo. You know, just like a real king cobra.
There’s no schematic or build plans for this project, but it looks easy enough to cobble together. Despite its simplicity, this game looks hilariously fun, and could quite possibly provide more entertainment through using the machine rather than simply building it.
No text description of this game can do it justice, so check out the video below. It looks like a lot of fun, and if you already have the parts in a bin somewhere, it’ll make a great weekend build.

The folks over at the Raspberry Pi Foundation often gets asked “does it run Minecraft?” Mojang, the team behind the block building game, has announced that they will be releasing Minecraft: Pi Edition. This port will be based off the Pocket Edition of the game, but with a revised set of features.
So what does this have to do with hacking? Mojang has announced that the Pi Edition will have “support for multiple programming languages.” There aren’t too many details about what this support will entail, but it looks to be aimed at teaching programming by using the world of Minecraft.
Hopefully, it will be possible to interface with the RPi’s expansion header to allow external devices to get data and create objects in the Minecraft world. There’s a lot of potential for hacking and learning programming skills.
The best part? It will be a completely free download. We’re looking forward to the launch.
I have often sat, gazing at my aquarium, wondering what life is like for those critters I keep captive. Are they bored and yearning to be set free? Are they content with their gluttonous lifestyle and constant pampering?
This is a question that is often raised with animals of a higher order, like pachyderm in the zoo, or chimpanzee. Those are easier to personify and to debate, but those are also, not often in our homes.
I keep my aquariums overgrown with actual live plant life. I have a flourishing ecosystem of natural plant filtration and invertebrates that I truly enjoy watching as they pick at the debris and bustle throughout the day. I test my water regularly to make sure it is optimal for the health of all involved. But my fish, well, as I said, I wonder about them.

[George] is a Neo Geo aficionado, and among his collection of paraphernalia, he has a MVS-Mini game console. His mini “Multi Video System” is a 2-slot model, meaning that it can hold two game cartridges at a time, which are indicated by plastic cards inserted in the cabinet’s face plate. Instead of swapping those cards out each time he changed cartridges, he thought it would be far cooler to install digital displays instead.
He scoured just about every retail store he could before finding a handful of small 5” digital picture frames that looked to fit the bill. After some careful cabinet modifications he had them wired up and ready for display. The frames don’t hold a ton of pictures, but they do support the use of SD cards. [George] says that he’ll likely just buy a ton of small SD cards, swapping them out whenever he changes games, though over time that might become as tedious as swapping out the plastic cards.
We would love to see [George] take his new digital display up a level, so be sure to share your ideas in the comments. Perhaps we can persuade him to automate things a bit.
A few years ago when [Dr. West] was wrapping up his collegiate studies, he put together a pretty cool coilgun for his senior project. The gun was built to simulate the Scorched Earth computer game in real life, but due to time constraints he was only able to build one turret instead of two.
The turret was constructed using mainly salvaged components, most of which came from old laser printers and desktop computers. The turret sits atop a computer PSU, which also happens to be the source of the coilgun’s charging power. A Rabbit 2000 microcontroller is used to drive the gun, which is something we’re familiar with from [Dr. West’s] past projects.
The gun can be aimed manually via the attached keypad, but we prefer the more authentic route, allowing the turret to aim itself after being fed X and Y coordinates. As you can see in the demo video, the coilgun works nicely, allowing [Dr. West] to hit a target from across the room.
We love the concept, and think it would be tons of fun to play a real life game of Scorched Earth with a pair of these turrets. If you are interested in making one of your own, you can find the writeup for his final project here in his public Dropbox.
[Tim Higgins] picked up an old pachinko game at a garage sale for his wife, but it ended up sitting unused in the garage for a few years. When he finally dusted it off, he decided that he wanted to restore and build a nice cabinet for it, though he thought the idea was a bit lame.
He says he likes to use some sort of CPU in his projects, and even though it was overkill, he made it his goal to add some sort of microprocessor to the game. He didn’t want to ruin the original aesthetics of the machine, so he decided that he could use an Arduino to drive a rewards system for skilled pachinko players.
Using some PVC pipe, he built a treat hopper which is controlled by the Arduino. When the player wins, the microcontroller triggers a small hobby servo, which dispenses gumballs/candy/etc.
[Tim] says that his wife loved the gift, and he was quite pleased with how it came out as well. Hit up his blog for additional build details and be sure to check out the photo slideshow of the restoration that we have embedded below.

If you happen to be in the market for some designer dice or need a set of custom dice for a game you have created, you could pay a ton of money to have them made, or you can do it yourself.
[Dicecreator] runs a blog dedicated to the ins and outs of creating DIY game and collector’s dice. This subject is not something that we would normally be interested in, but one particular item caught our interest – DIY toner transfer dice. Very similar to the process of creating a toner transfer PCB, he walks through the steps required for making your own dice with very little overhead.
The steps are likely quite familiar to those who have fabricated your own PCBs at home. He starts out with blank dice, sanding the sides down with increasingly fine sandpaper until they are ready for the transfer process. An image is printed on glossy inkjet photo paper, which is then applied to each die with a standard clothes iron. After a bit of soaking in water to remove the excess paper, the die is ready to go.
Sure it’s not exactly rocket science, but it is a cool little trick that would work quite well if you are trying to replace a lost die or if you simply want to make a fun gift for a friend.
