This device is a prank or gag that [Eric Heisler] came up with. It will intercept IR remote control codes and play them back after a bit of a delay. The example he shows in the video (embedded after the break) catches the television power signal from a remote, then sends it again after about thirty seconds. This shuts off the TV and would be extremely annoying if you were unable to find the device. Fortunately (for the victim), [Eric] included a piezo buzzer that Rickrolls after sending each code. Just follow that tune to find the offending hardware.
He chose to use an ATtiny10 microcontroller. It looks like it’s realizing its full potential as the six-pin package use all available I/O to control the IR receiver module, an IR led, and the buzzer. It runs from a coin cell without regulation and the circuit was free-formed on a tiny surface mount breakout board which hosts the microprocessor.
There was a time when posting a fake story was fun for all involved. But in this age of constant trolling, it’s near impossible to pull it off with our savvy readership. Instead of letting you down with a really poorly advised how-to, we’re putting in a call to hear what you’ve got in your own bag of pranks. Consider this another holiday theme and tell us what you’re planning for April Fools’ Day.
As always, we’re looking for your own posts on the topic. We always want to give credit where it’s due so post your prank on your blog or other favorite corner of the interwebs and send us the link. Don’t have a place to put it? You can always start a thread in our project log forum, or check out this for additional spots to stake your claim.
In case you need some help coming up with something, we’ve got a few examples to get you thinking. You can go the route of fake video demonstrations like this Gmail gestures hoax, or the more recent Human BirdWings Project. But those require a lot of production time and a clever seed idea. Perhaps something really simple will go a long way with the roommates. We’re thinking soap covered in clear nail polish to prevent sudsing, or perhaps you want to reconfigure your router to render pages upside down. We can’t wait to see what you come up with!
It looks like a genetic leap has unleashed the age of mutants, but this is really just a few guys trolling New York City with some custom RC aircrafts. The video after the break shows the fliers up close. They’re pretty much full size, we’d guess 5’10” from head to heel. The outstretched arms and body act as wings, while the legs act as ailerons and rudders. But from afar (or even a medium distance) it’s quite difficult to make out the flat surfaces… they look like office workers loosed from their cubicles.
Unfortunately we don’t have more than a flight demo to share with you. If you know where to find build info (or any extra details at all actually) don’t forget to send in a tip. We wonder if these are the same guy who made the flying hero we posted back in July?
There’s another nugget of delight right at the beginning of the video. A sweet octocopter which looks much like this one was used to capture the aerial footage.

You all know that person.
The one who picks up every present with their name on it, shaking it before busting into their best Carnac the Magnificent impression. Heck, you might even be that person.
[Jason] was thinking about how to combat the gift shaker in his life and put together a simple prank that’s sure to provide him some enjoyment when the shaking and guessing commences.
He bought a premade audio module that stores about 20 seconds of sound, replacing the pushbutton trigger with a pair of wires that can easily make contact when the box is vigorously moved. Everything was carefully mounted in a gift box before being wrapped and set under the tree to surprise the eager gift shaker.
We definitely like the idea, since there are a plethora of ways to customize/enhance [Jason’s] work to fit your specific needs. Whether you go with the kitten/puppy in a box theme, or wire in an incredibly loud alarm, your resident gift inspector will never look at presents the same way again!

[John] likes making things out of unusual junk, and decided to build something for the sole purpose of trolling others. He thought it would be funny to stuff a new digital camera into the body of an old, obsolete camera, just to see how people would react to it.
He considered several different cameras, including a bulky old Polaroid, eventually settling on a far more manageable Argus C3. The camera wasn’t quite big enough to fit his new digicam inside, so he built a mock body using black micarta. He attached the Argus’ front and back to his plastic box, then spent some time fitting his digital camera inside. He transferred knobs from the original camera to his new false body, adding to the authenticity, before taking it out for some test shots.
You can see the final result above, and we think you would be hard pressed to notice that there’s something amiss with his camera unless you spent some time taking a closer look at it. He says that it works well for the most part, and it’s definitely a conversation starter. People are always puzzled by the fact that he is using such and old camera, and doubly so when he tells them it can take about 4,000 shots before he has to “develop” his pictures.
Being a long time prankster, [cyclonite] came up with this pretty clever hack in an old USB flash drive.
The drive was removed from its case, and the stock memory and controller was removed. On the back, an attiny 2313 is glued to the pcb, while resistors are swapped to work with the VUSB library. Wirewap wire is used to jumper all the needed points to the new micro controller on the back, and a temporary ICSP header was fitted on the end to load software.
What your’re left with is an innocent looking usb drive that, when plugged in, sets itself up as a keyboard then proceeds to toggle the caps lock on your victims computer every few minuets. Classic.
Join us after the break for a quick video.

Even though it’s a bit late for April Fool’s jokes, [Ameres] wrote in to share a project guaranteed to catch your friends (or enemies) by surprise.
Like us, he had some old CD-ROM drives sitting around and thought that there must be some way to put them to good use. He gutted one, saving the laser’s carrier unit for use as his mechanical trigger. He placed the unit above a doorway, soldered a pin on to the end of the laser carrier, and positioned a water balloon at the end of the CD-ROM’s rails. The laser carrier’s motor was then connected to a photocell located about half way down the side of the door.
He mounted a laser on the far side of the door, which is pointed at the photocell. Once the laser beam is broken, the CD-ROM motor is actuated, popping the balloon over the unsuspecting victim.
It’s not the most high-tech prank out there, but how high tech does a water prank need to be? We just wonder how easy it would be to attach one of these things to our cube at work…
Have any ideas as to how he can make a bigger splash with his friends? Share them with us in the comments.
