Here’s a killer 3D-holographic display made with Kinect, you can see all of helicopter’s views from different angles when you move around the display. It’s not really “holographic” as in popping out from the surface but this is certainly an effect that might be implemented in future displays including our smartphones, tablets, and other portable devices.

POV or Persistence of Vision where you use flashing LED lights to display letters in motion, has always been a fun way to learn about LEDs and circuits. You might remember I invented the world’s first Golf club POV, which was capable of showing letters/images while you swing the golf club.
Well, there’s a DIY Doggy Style (literally doggy dog) POV someone has managed to put together with his furry little helper helping him in pitch darkness.
Mounting 5 LEDs on a moving o
Here’s a really funky project Jeremy Cook invented from scrap parts incluing his old RC car. The result? Really creepy box that sorta comes alive. Muhahahahaha.
This reminds me of the World’s Most Useless Machine, only a bit more creepier.
Imagine your livingroom/playroom filled with LED lights and animated LED shelving.
Now imagine it syncing with your favorite music and you can have a small group dance party!
The shelves and ceiling have a refresh rate of 30Hz and can generate over 30 thousand colors per pixel. A pixel is a single shelf or can light in this case. Not bad for a few bucks and hours of spare time. Best part, Both the shelves and ceiling consume less than 50 Watts when fully lit. And less than 10 on average when in
I still remember the first printer I had back in 1989, it was “color” dot-matrix printer, top-of-the-line and cost me(or my dad) couple hundred bucks. It was so cool to see bunch of MS-DOS text printed in color, those were the days you rejoiced because you had 256 different colors and printing one page took only a minute.
Well, here’s a cool DIY project to remind you of that, a DIY smartphone dot-matrix printer (sorta) that you have to hold manually. Actually it’s more like art and prints
We’ve seen a guy who made a DIY Geiger Counter before, for those of you who want to build your own to detect radiation (yes, that what Geiger Counter does, detect radiation, you can read all about it on WikiPedia), you can get this DIY Geiger Counter Kit and build it easily, just some soldering and assemble required.
The DIY Geiger
Check out Harrison Krix who spent the last 17 months building this fully-functional DIY Daft Punk Helmet. This is the most awesome DIY project I’ve probably seen for the last 17 months with every gory detail mastered to perfection. This would be the ultimate helmet to wear to a rave concert.
Here’s a time-lapse video of the DIY Daft Punk Helmet in the making:
5 years ago, it was a lot harder to build your own solar-charging systems but now there are so much more resources plus price of solar systems have dropped quite a bit. If you own a home and you have some space in your backyard (or roof) for solar panels, there’s absolutely no reason why you aren’t powering some of your home electronics via the power of the sun (unless you live in Alaska and it’s no-sun season).
Here’s a great example of a DIY portable solar charging system
Do you want to annoy the crap out of your neighbors, not by building a 480HP car that deserves to make all the noise it wants but by building (probably less than 5HP) scooter that uses the most annoying fan in the world and its top speed is about 2MPH?
Well, now you certainly can as the guys from MIT who built the infamous shopping cart with a fan have finally graduated and built something even better, th
Here’s an incredible DIY LM555 Adding Machine that Alan Yates built, it can do adding and subtraction using method of complement numbers. This is like a digital version of old Adding machines people used to use back in the day.
The device was built with experimentation and modular testing in mind. Each decade ring is independently resetable and most multi-drop signals have diode isolators. Si
