The circuit uses three extended-duty astable 555 timers to control the brightness of the 5050 RGB common-anode LED strips that run up the sides of the 24″ x 12″ x 1/4″ acrylic panels. Each of the three panels was laser-engraved at 600 DPI on an Epilog laser engraver and features a different aspect of the poster. There’s one for Snowden, one for Daniel Craig, and one for the text.
[Wilywyrm] tied the color channels together in the first panel to output white light. He used red for the second panel and blue for the third. A complete list of parts with build notes is available on his Google Drive. [Wilywyrm]‘s notes include improvement ideas, like making all the RGB strips color-adjustable with more 555s or a microcontroller and timers.
At the beginning of the fourth Bond film, 007 escapes from a French château with a jetpack. While the jetpack has yet to take off for those of us who aren’t secret agents, there is a way for anyone to fly just like Bond. It can’t lift a full-scale human yet, but [Rodger]‘s Project Thunderball can let a mannequin hover for several minutes.
The stand in for [Sean Connery] in [Rodger]‘s build is a 2.2 lb mannequin – actually an ‘inflatable companion’, if you will – stuffed with styrofoam peanuts. The actual jet pack is a quadcopter souped up with larger motors, propellers, and enough batteries to deliver 1kW. There’s no belt for this quad; the mannequin rides the machine like you would a horse, straddling the electronics while very high-speed props spin just inches away from the tender bits of an inflatable plastic doll.
[Rodger] is able to get about 8 minutes of hover time out of his quadpack, an impressive feat that also allows his flying machine to deliver beer and pizzas.
Years ago we covered using thermite to destroy a hard drive. The idea is that if you melt through the platters, the data is completely unrecoverable. There are tons of videos of people doing this, but they all have a similar format. There’s a hard drive, with a flower pot or soda can sitting on top full of thermite. They then light this with a strip of magnesium and a torch.
I wanted to do something a little different. I wanted to implement thermite as a self destruct mechanism inside the device. To do this, I had to come up with a way to ignite the thermite. This stuff is very difficult to light. You have to get it really really hot. The easiest way is to use magnesium, which itself isn’t the easiest thing to light.
What I finally landed on was an ignition system that uses model rocket igniters, gun powder, and magnesium to light the thermite. The model rocket igniter can be set off from the 12v line inside your computer. However, it isn’t hot enough to light magnesium shavings, much less thermite. To get it to work, I needed to add some gunpowder. A small amount of gun powder would get hot enough to light the magnesium shavings, which in turn were hot enough to light the thermite. I had to be careful though, because too much gunpowder would cause a rapid expansion, blowing the thermite everywhere instead of lighting it. You can actually see some red thermite being blown out of the external hard drive and the laptop as the gunpowder ignites.
Effectiveness of external hard drive self destruction:
I wasn’t sure about this one. There isn’t a whole lot of space for thermite and the ignition system inside the box. On top of that, the only space was at the side of the hard drive, where the walls are the thickest. I had no idea if the small amount of thermite I used would penetrate the drive. It did, just barely as you can see in these pictures. It looks as if it pooled in the screw holes and made it inside. The platters are damaged.
Effectiveness of laptop destruction:
I decided to completely replace the cd rom with thermite. This gave me a ton of space to put things. I was pretty positive this would work. The hard drive is in the center of this laptop, which meant I had to place it on its side for this to be effective. You can see the thermite work its way down toward the drive in the video. As you can see in the pictures below, the drive cover is completely gone and the platters are destroyed. Success!
Since this system can be powered by batteries or the internal power of your computer, it can be put inside a working device only to be used when needed. Obviously it is a ridiculous fire hazard that no one should bother with. It was a fun experiment though and I really feel like it is something that would fit in well in the world of [James Bond]
Hopefully you’re not on a network that blocks YouTube, because we’re sharing videos that show off three different projects. Alas, they don’t give any details about the development process, but we think you’ll like seeing the end results just the same.
Bust out your Arduino and give theoriginal video game a go. This game of Pong is played on an oscilloscope using two micro-trimpots. To make it happen a pair of MCP4901 DAC chips are feeding the probes.
The video was debuted this past week at the TED2012 conference, giving [Daniel Mellinger, Alex Kushleyev, and Vijay Kumar] from the University of Pennsylvania GRASP Lab, a chance to show off their amazing robotics work. The team used a set of autonomous quadrotors to play the [James Bond] theme, complete with keyboard, drums, cymbals, guitar, and maracas.
The coordination of the robots undoubtedly took an incredible amount of time to orchestrate, but after watching the video we think it is well worth the effort. Now of course you can’t simply input a piece of sheet music into the quadrotor control system and expect them to play it, but we imagine that time will arrive before you know it!
