April Fool’s Day was last Friday, and the Internet was garbage for a day. Our April Fool’s prank was amazing, and in a single day garnered more views than the Raspberry Pi 3 launch announcement from a month prior. There just might be a market here for Apple. Here’s a short roundup of some of the best electronics April Fool’s posts:
This, surprisingly, was not an April Fool’s post. [Dave Jones] has been looking to upgrade his workspace for a few years now. He’s finally found a place. It’s the old Altium office in Sydney. [Dave] worked at Altium before spinning up the EEVblog, so this really is his old stomping grounds. It’s 4000 square meters (43,000 square feet), and exactly 3950 square meters larger than his current lab. What is he going to do with all that space? He’s looking for suggestions, but I would suggest an awesome model train layout. A [Dave Haynie]-style tour would also be acceptable.
Yesterday was the unofficial geekhack / deskthority / r/mechanicalkeyboards SoCal Mechanical Keyboard meetup at Datamancer in Montclair, CA. I was there, got a Control key to replace the Caps Lock key on my Novatouch, and took a lot of pictures.
It’s a presidential election year in the US, and that means millions of people are going to make America great again by polluting their front yard with campaign signs. These campaign signs are usually made out of coroplast, a material that looks like corrugated cardboard, but is made out of dead dinosaurs instead of dead trees. Coroplast is a very interesting material, and [uminded] tipped us off to some guy that makes mini speedboats in this rather uncommon material.
There are some things you just shouldn’t do. Combining octocopters with chainsaws, for example. You shouldn’t do it, but someone will anyway, and YouTube exists. Here’s an octocopter with a chainsaw.
Foxconn is buying Sharp. Sharp has a rather large portfolio of LEDs and optoelectronics, but this deal is mostly for Sharp’s large contract manufacturing business.
It looks a little bit like an octocopter, but this solar-powered hovercraft is distinctly different from its free-flying brethren. It depends mostly on ground effect for operation and to get it just a bit into the air you need a pretty large reflective rig nearby.
The vehicle needs to be even lighter than traditional quadcopters in order to function. It doesn’t carry any battery at all which presents a problem when trying to program the microcontroller board. For this it is connected to an external battery, which is removed before flight so that the control can be powered from the solar array.
What’s not shown in the image above is a mirror array used to focus more intense sunlight on the panels to bump up the available electricity. Not much is said about this, but there is one image on the project page which shows the creator standing in front of the set of four mirrors (perhaps sheets of mylar?) strung up between a couple of trees.
Alas, we couldn’t find a video of the aircraft in action. With such a delicate balsa wood frame we’re sure this thing is affected by every air current that passes its way.
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.

So you’ve got a $40k+ RED Epic video camera and you need to get it from all the way down here to all the way up there. Sure, you could rent an expensive crane and take your shots from above that way, but why bother with that when you can fly instead?
German video effects company OMStudios decided that it was up to the task of finding a crane alternative, so they built a crazy octocopter drone to get the camera up to where they needed it. Figuring that if four rotors is good eight is even better, the group’s octocopter lifts the camera to heights of up to 150 meters, which is pretty impressive considering the weight of its payload.
While we might be a little hesitant to trust such an expensive camera to a glorified RC helicopter, it actually looks pretty solid from the video. Besides, we’re pretty sure these guys know what they are doing since they have a RED camera in the first place.

Above you can see
Doctor Wily a Chinese hacker starting up one of the propellers on his octocopter. It seems that the man is using a collection of eight motorcycle engines, each with its own wooden propeller to create an eight-bladed helicopter. We were able to locate some video footage of his experiments, which you’ll find embedded after the break. As you can see, this is perfectly capable of flight, but we’re not quite sure if we’d call it controlled flight just yet.
The video starts off showing all kinds of hack-ity activities, like tightening the bolts on the propeller and priming the gas lines by sucking on them like a straw (mmmm….. high-octane!). Coke bottles serve as the gas tanks, and you’ll want to keep your hands inside the vehicle because there’s no cages to keep them out of the hand-started propellers. Although we don’t speak his language, we did understand the demonstration of the controls that the man gives, showing an earlier model with rings of fabric around four of the propellers meant to help direct the downward thrust as a steering mechanism. We don’t think this will be viable until there is some type of PID system that predicts the performance of each motor and makes quick adjustments to keep the craft balanced. None-the-less we were glued to the screen hoping that this turkey would fly.
