Who’s Hungry? Cannibalizing a rubik’s slide

photo 1

This strange looking toy is the Rubik’s companies attempt to create an electronic puzzle cube style game. The Rubik’s Slide is a speed based game where you have to slide the corners to change the shapes on the LED Matrix to make a certain shape. The game itself is fun for a while but gets old fast, and apparently  breaks easily. I recently found my Rubik’s Slide (I recently moved) and was disappointed to see that it was no longer functional. So this week we will be cannibalizing this toy and I hope to get some good electronic components as well as some structural parts.

To open this up I removed the battery cover and removed four hidden screws. The inside snapped out into three pieces connected with wire through the center to separate these I snipped the wires. The picture below shows the internals…

After cutting the wires and separating the three layers I was able to remove the circuit boards. There were about 4 unusable buttons that got scrapped and the LEDs were unable to be removed. Besides that I got the following parts…

– The top 3x3x3 panel for a LED matrix

– The center as a plastic structure

– The bottom battery holder

– 1 Three way switch

– One speaker (It’s Green!)

– 5 push button

– 4 Pins

– Various plastic pieces

DIY minecraft steve head mod

I was at the mall recently and came across a cardboard steve head at slackers (a video game and music store). Minecraft is the hit video game developed by Notch and licensed to Mojang. In this game you try to survive in a sandbox environment by mining Ores and developing more advanced tools and weapons. Steve is the main character of this game and is the pre-loaded skin for all players. After purchasing my new toy I did what I usually do, I tried to Mod it. I started out adding the headphones on the outside shown in the picture below. To make these I took the printed design (drawn in photoshop) and glued it onto cardboard to show the 3D effect. I then hot glued the Headphones to Steve’s head and let it dry.

After finishing the headphones I played around with it and realized it would be super cool if those headphones actually worked… So I grabbed the speakers and Aux cable from this weeks edition of “Who’s Hungry?” where we canibalized a  speaker set. I drilled holes in the head and attached the speakers thusly. Then I soldered in the Auxiliary cable and was able to get the speakers to play music when its hooked up to my iPhone.

The speakers are awesome and people don’t believe me when I tell them that these “cardboard” speakers work. The face they get when I start playing music from the head is priceless. The design was simple and the result is epic! Definitely one of my favorite mods, and just in time for halloween.

GBA4IOS hack allows third party app download without a jailbreak


I recently bought the new iPhone 5c with iOS 7 preloaded. I was browsing the internet when I saw a link for downloading a GBA emulator on your iPhone without jailbreaking it. Initially I thought that this must be a joke, scam, or virus? But with further research I learned that, not only was it legit, it works very well! Its a simple installation and I will walk you through installing the app, installing games, and how to fix it if it crashes.

Step1 – This is the most important step. Set your iOS devices date back before January 2012. This is the exploit that allows the third party app to install, without this your app will be corrupt and will not function properly.

Step2- On your device visit …

And navigate to the download section.
Step3- Scroll down until you find GBA4ios  and click install. Wait a few moments and you should be redirected to your home screen where an app is being installed.
Step4 – When it is finished installing tap on it to launch it, you should see a list of white spaces, this is where your games will be located when you install them. So lets get some games! Note – Your iOS device’s date must be set before January 2012 to install games
Step5 – For this step we are going to install a classic favorite, Pokemon Fire Red. If you open GBA4ios and click the search bar in the top right corner you will be redirected to in safari.
Step6 – Now search for Pokemon Fire red and slick download. This might take a little bit of time but eventually a screen will pop up with the file on it. There will be an “Open With” option, tap that and select GBA4ios.
Step7 – Go back to your app and select Pokemon Fire Red, you should see the game start up.
Congratulations! Your iOS device now functions as a Game Boy Advance, the download process is the same for all games. once you have the games installed you can set the date back to auto. If the app refuses to open the go set the date back, open the app, then set the date back to auto. Your app will now work. Comment below if you have any questions about the installation process.
Note – Along with this app there are several other applications you can download through…

 Such as a NDS emulator, a GBC emulator, a SNES emulator, a Torrent Client, and a screen recorder.



Who’s Hungry? Canibalizing an old Speaker circuit…

Its time to serve up a fresh plate of free components! That’s right nerds, this week we will be tearing down an old speaker circuit for parts. I already removed the main circuit and the speakers from the casing. The speakers popped right out and the circuit was unscrewed.


Now lets take a closer look at the circuit…


It looks like we have a large amount of capacitors (useful), some varistors (useful), a power port (useful), a potentiometer (very useful) and what looks like an AV in port (not so useful). The IC is basically useless, even if I could un solder it theres no point in using it. Now that the circuit has been analyzed and we know what we want to canibalize we can get started with the deconstruction of the circuit.


As you can see I have already removed some components in this picture, but basically I am cutting the PCB into smaller segments to work with. This allows me to be more precise in the desoldering. I will heat up the solder and then slowly pull out each component from its spot in the board. After only twenty minutes I was able to finish canibalizing the board and gained 11 capacitors of varying charges, 11 varistors of varying Ohms, the power port out, the AV out and the potentiometer (along with the two speakers already removed).
