For the Deconstruction decentralized hackathon, “The FABricators” from Fab Lab Tulsa built a Street Art Bot . The robot drives around and dispenses liquid chalk in a pattern to make sidewalk art. The FABricators’ robot is based on an electric wheelchair platform. Attached to the base ...
Ironically, a lot of the nicer dance pads (hard mats) are actually built for multiple systems with breakout ports (DB-9′s, usually) that just short pins to a common ground when a panel is stepped on; they’re made this way so that you can buy a small box that will adapt it to a differe...
Want to run your 3D printer without your laptop attached? Looking to make your hackerspace printer network accessable? OctoPrint aims to make a 3D print server for the Raspberry Pi. The open source Python project allows you to upload and manage GCODE files on the RPi. You can then sel...
The solution for “remote” triggering is that black cable which physically attaches to the shutter button. Just depress the plunger at the opposite end and a picture will be snapped. This process is automated with the use of a hobby servo hidden inside the box. It’s driven by an Arduin...
If you find yourself in the West suburbs of Chicago, IL with nothing to do you should head over to Workshop 88 . [Andrew Morrison] shot some video at the last public meeting which includes a tour of the facilities. We’ve embedded it after the jump for your convenience. The clip isn’t ...
The problem with laser etching dark materials is that the areas burnt away by the intense light don’t really stand out from the rest of the surface. [The 5th Fool] is taking a roundabout way of correcting this by topping his laser engravings with contrasting paint . The technique is s...
[James Glanville] wrote in to show of his latest tube project. It’s a clock using six IV-3 VFD tubes . In addition to the tube displays the project prominently features a blue 3D printed case which hides away all the guts of the build including the Stellaris Launchpad which drives the...
Inspired by playing The Legend of Zelda video game series, Cornell University students [Mohamed Abdellatif] and [Michael Ross] created a Virtual Archery game as their ECE 4760 Final Project . The game consists of a bow equipped with virtual arrows and a target placed about 20 ft away....
This is 100% true. I can’t be completely sure that this is what caused the problems (personally, I think the fact that he used polish remover instead of pure acetone is probably the real problem) but I can vouch for the accuracy of this comment. My previous jobs was working for a majo...
So you’ve got a project running on an x86 board and you’d like some GPIO pins. Whether you want to read a few buttons, light up a few LEDs, put an accelerometer in your computer or whatever, you’ve got a problem. Luckily there’s an easy way to get 24 GPIO pins on an x86 board using a ...
The screen is an eGalaxy 7″ touch sensitive module he picked up on eBay. It sounds like it was meant for a backup camera in the dashboard of a car. He compiled his own Linux kernel to add support for the screen. It uses HDMI for the video interface with the driver board, and the touch...
CrashBangLabs in Regina recently got their hands on a laser cutter. The Full Spectrum cutter was donated by a local company, who were upgrading to a larger machine. With no laser cutting experience, [Brett] decided that his first project would be laser engraving his iPhone 5 . This is...
It should come as no surprise the Hackaday tip line is regularly flooded with press releases. Everything from an infographic comparing Call of Duty 3 to Battlefield 3 (yes, totally serious), announcements that a company we’ve never heard of is getting a new CFO, to the business propos...
Over the last few months, we’ve seen our fair share of pentesting appliances. Whether they’re in the form of a Raspberry Pi with a custom distro, or an innocuous looking Internet-connected wall wart, they’re all great tools for investigating potential security vulnerabilites at home, ...
We’ve seen a few of the projects from The Deconstruction, a 48-hour build-a-thon for hackerspaces and other groups around the globe. Of course Tymkrs, a pair of geeky vloggers famous for their building prowess, were part of The Deconstruction, and in the process they came up with a fe...
For as much as we enjoy rockets, explosives, and other dangerous things, we haven’t said a word about the works of [Richard Nakka] . He’s the original hacker rocketeer with thousands of words dedicated to the craft of making things move straight up really fast. One of his more interes...
Take a look at the image above to see his alterations to the mainboard. The jumpers soldered to the two chips at the top are by far the trickiest part of the project. Each of the pins he soldered to needed to first be lifted from the PCB pad so that they no longer make contact with th...
Look, we understand the need to find a project to occupy your time and interest. So we’re not going to ask the wrong question (why?) for this one. This guy hates the creme that connects the chocolate cookies to make an Oreo. So he built a complicated system to separate the cookies and...
One of the issues with extruder-based 3D printing is that it can be very difficult to print objects that have voids in them. You simply must have something to deposit the soft material on until it has a chance to harden. [Matt] found a solution which should work for any extruder-based...
Here’s an interesting hack. It’s a small pick-up truck with a Dope Cannon attached to it . Sure, it looks more like something you’d see in Syria , but this item was actually seized in Mexico where it was being used to fire 30 pound slugs of Marijuana over the border fence with the US....
Here’s a camera rig that makes it a snap to produce photorealistic 3D models of an object. It was put together rather inexpensively by an indie game company called Skull Theatre. They published a couple of posts which show off how the rig was built and how it’s used to capture the mod...
Well here in the States we have the same thing, call them cattle guards, why they became to be call that I don’t know. I’m not that sure you would want to use two cattle guards here. They get in a hurry one might get jostled into a cattle guard, and break a leg. Aldo some use swing ga...
Xbox 360 control for a toy heli [Jason] leveraged the IR control libraries for Arduino to use an Xbox 360 controller to fly his Syma S107G helicopter . Windows 7 running on Raspberry Pi Why, oh god why? Well, the guys at Shackspace got their hands on a laser cutter that can only be dr...
[Dave] wanted to show off a project at his 4th-grade son’s school during their family science night. We haven’t heard of an event like this before but it sounds like a fabulous idea! He had a new laser he wanted to include in the project, and noticed that his son was learning about ho...
The business end of the bending tool is the red-hot Nichrome wire running through the aluminum channel. That channel is used to protect the MDF and act as a spacer so that the wire doesn’t touch the acrylic. On the near side the wire is anchored with a screw, but on the far end it is ...
Perhaps type acceptance would be an issue. As hams the FCC does allow us to build or modify our own devices but we aren’t allowed to market them without type acceptance. I’m thinking you would have to take a two-micro approach. One controls the transmit vfo/power while the other is th...
The 2013 Uzebox Coding Challenge is currently underway. This competition runs until June 1st, with registration open until April 1st. The Uzebox is an open source, 8 bit game console that uses only two chips: an ATmega644 microcontroller and a AD725 RGB to NTSC converter. We’ve featur...
We understand where [John Clarke Mills] is coming from when he says he wants a home theater but not at the expense of dedicating a room to it. His situation is a bit more sticky than most folks in that he has a beautifully kept Victorian era home. Recently he was removing a renovation...
Why do many people think everything posted to hack a day has to be a market ready product, ready for shipping with a defined ROI and small business plan for people to enjoy it or that they need to step in and validate the usefulness based of a project based on a narrow world view to b...
a 3D printed Hemispherical Omnidirectional Gimballed Drive system which you can make at home . That’s a mouthful which is why it is commonly referred to as a HOG drive. Never heard of one? Well you need to keep up with your Hackaday because about 20 months ago we featured this amazing...
