[Ken Foster], owner and creator of this $40K+ beast, worked with welder [Gary Webb] to custom design and fabricate every component of the vehicle, from hinges to hydraulic systems. They claim not a single part came from a box. The cooking area, complete with speakers and spotlights, h...
The narration and subtitles of the video found after the break are both in Portuguese, but it’s not hard to figure out what’s going on here. He begins by using double-sided foam tape to secure the piece of copper clad board to the hard drive platters. You’ll want to center it as best ...
Dispensing change for low-stakes gambling March 9, 2013 By Brian Benchoff Leave a Comment Every year, [Nathan] hosts an Oscar party with a lot of drinking, adoring the off-color comments of [Joan Rivers] and some low stakes wagering. Everyone throws a dollar into the pot for a particu...
Thought of the same thing aswell when i first learned about peppers ghost, but i don’t think it would work in the context your giving. you’d just get a strange image that can only be viewed from one angle, you wouldn’t be able to rotate around it and see different ‘views’ because the ...
At this point the series includes six lengthy segments. The first episode, which you’ll find embedded after the break, starts with an external overview of the hardware. [Mike] mentions that it’s not functional at that point. He guesses that this has to do either with security settings...
None of it is. It’s got a static sound to it because this was about the best you could by rapidly changing the volume of the SID chip to play a rudimentary digitized sample. The C64 was never designed to play digitized samples and so it was a hack that worked although very primitive. ...
In regards to bandit’s comments, they are something the abled bodied community may no be able to understand. Alex’s comment goes to show that those within the disability community can’t fully understand the experiences of others within the community. I don’t think it’s not that bandit...
This is [Wpqrek's] Commodore 64 modified to go on the road with him . The elderly machine has a special place in his heart as it was what he learned to code on. He performed a series of hacks which house everything necessary to use the machine inside the original case. Obviously the h...
A 2:1 gear reduction slows down a spinning shaft to half speed and doubles the torque. Repeat this a few times, and you’ve got a ludicrous amount of torque moving too slowly to see with even precision instruments. That’s the idea behind [Jeshua]‘s project, a Printed Machine partially ...
If you’re making a GPS-enabled project, you may have noticed the commonly available GPS modules are pretty expensive – usually around $50. Here’s one for $8 . It’s a U-blox PCI-5S GPS receiver on a PCI Express card. There are test points for serial and USB data, though, so fitting thi...
Here’s an interesting build that combines light, sound, and gesture recognition to make a 360 degree environment of light and sound. It’s called The Bit Dome , and while the pictures and video are very cool, we’re sure it’s more impressive in real life. The dome is constructed of over...
I recently completed a PCIe soft IP core design; the connection between the core and the PHY was 250MHz (4ns). You’re required to use time constraints (and give it an idea of how long each trace is between the FPGA and PHY) to get it to work. That was using a device without built-in P...
You shouldn’t be surprised that the event posting starts with Peep waterboarding. But from there the rigs do get a lot more creative. For instance, the electric chair above connects the bunny to a stun gun (there’s no mention of what that big set of capacitors has to do with this. The...
I had the idea to make some kind of alarm that would go off if anyone but me removed the wallet from my pocket. A quick google search revealed tons of wallet alarms, but I noticed that they all had a credit card form factor(that’s good) and would make noise when exposed to light(that’...
Children of the information age are doomed to have the worst handwriting just for lack of use if nothing more. But some students at Olin College harnessed technology to find a solution to that problem. Meet Herald, a CNC machine that can produce beautiful calligraphy . The machine use...
Using just a few ordinary around the house items, [The King of Random ] turned a cordless electric drill into a human powered electrical generator. If the drill is run in reverse and cranked by hand, the generated energy can be transferred through the battery terminals to a connected ...
“I don’t understand, you don’t have the technology.” OK, so it’s not actually a futuristic tool with the same capabilities as the one off the hit TV series Dr. Who, but this homemade “sonic screwdriver” is a multifunction device that’s pretty cool nonetheless. Created around an Arduin...
SMD components may be a little challenging for the home builder – even though the’re inordinately practical for homebrew PCBs – but if you play around with electronics and solder long enough, you’re eventually going to run into the horrors of BGA parts. Instead of convenient pins, BGA...
The sword on the left has an electronic stun mechanism built into it. it works by energizing two blades which are separated by nylon bolts and spacers. Look closely at the tip and you’ll see the blue glow which indicates high voltage. To shock your victim you have to touch them with b...
The first part shown in her video (embedded after the jump) is to make a mold for the candies. You probably have a few bags of LEDs in your parts bin. Those along with a trough made of foam core come together to create the form for the silicone mold. After mixing, pouring, and hardeni...
In a testament to both his technical ability, and possibly even more so his tenacity, [Chris] was able to get Debian 6.07 running on a PowerMac destined for destruction. He had slated a few hours to upgrade this 56 Megabyte monster, but it turned out to be a several-day event. Those t...
Ahhh space. The final frontier. While many people dream of one day becoming an astronaut (and possibly battling aliens or cylons), it’s a select few who actually make it their reality. Fortunately for us, there’s a middle ground that allows the masses to still have some fun in the sky...
[Brian] has brought together a powerful collection of hardware to build a robot. The end goal is to have a robot that’s controlled by a Wiimote . The Wiimote communicates over Bluetooth with a Raspberry Pi, which is running a Python script. This script uses the CWiid Python module to ...
This innocent looking Maglite houses a piston and barrel, making it into a functional pneumatic BB gun . A Maglite was chosen due to its high durability, and easy access to the internals. A schrader valve sticks out of the battery cap, which allows the gun to be charged using a standa...
If you want to check your house for hot air leaks, take pictures of the heat coming off a rack of equipment, or just chase the most dangerous animal, [Arnie], through the jungles of central america, a thermal imaging camera is your friend. These devices normally cost a few thousand do...
We’ve seen our share of replica props, but [Nathan]‘s replica of the spy’s sidearm from Team Fortress 2 is the bee’s knees. The build began as an off-the-shelf Airsoft gun. After removing the barrel and cylinder, [Nathan] used Apoxie Sculpt and a whole lot of sanding to turn a stock p...
This thing is so cool it almost looks fake. But [Matt Richardson] isn’t a hoaxster. He actually built what might be called a heads-down display for your bicycle . He refers to it as a headlight because it borrows a similar function. It mounts on the handlebars and shoots light off the...
[Christopher] is really going the distance with his liquid-filled 3D printed lens project . The idea is to create a bladder out of two pieces of clear plastic. It can then be filled with liquid at a variable level of pressure to curve the plastic and create an adjustable lens. He was ...
The rig pulls a printed object up from the ooze on the build platform. They’re using resin that is cured with visible light. That’s why you see the level in the foreground; the bath needs to be a uniformed thickness so that it solidifies correctly when the light hits it from the under...
This isn’t a thrift-store coffee table modified as a craft project. [Dandujmich] built it from the ground-up using framing lumber, bottle caps, plastic resin, and some electronics for bling. The first step was to see if he had enough caps on hand for the project. It’s hard to grasp ho...
