The frame consists of aluminum struts that crisscross through an all-steel body, which sits on casters for mobility. This is a good thing for… well, everyone! The company responsible for this beauty, Ideum, has discontinued the MT-50 model in favor of an LCD version, and has released the plans for the old model as part of the Open Exhibits initiative. Wander through a well-funded museum these days and you’re likely to find interactive exhibits scattered around, such as this sleek 50″ projection-based multitouch table. We like how he’s labeled all his handiwork for any future hacker who might open it upĬontinue reading “Hacking An Industrial 42″ Multitouch PC” → Posted in Multitouch Hacks Tagged multitouch, touch screen 50″ Multitouch Table Is Expensive, Indestructable He also added a breakout board with relays for power management, eliminating a seven watt continuous draw when in standby mode.īe sure to watch the video to the end where he leaves us with a tour of the hacked interior hardware. He also replaced a small speaker with a larger speaker and amplifier, giving a volume and sound quality difference that’s like night and day. At that point, we’re pretty sure we see him spin up a hard drive platter with a sandpaper disk attached to it, forming a bench top disc sander and making us like this hack even more. Be sure to watch carefully in the video below where he’s attaching a magnet and cord to the potentiometer, and encasing it all in epoxy. Moving on to the hacks, he added brightness control by using a potentiometer to control the power to the backlight. The source of this turned out to be yellow goop on the PC’s power supply that had turned conductive across a resistor. A few hacks later and he has us all suitably envious.īefore hacking away though, he had to take care of some magic smoke. We’re slowly moving in the direction where everyone will have a touch screen desk like in the 1982 TRON movie or in the 1987 Star Trek: The Next Generation series with its ubiquitous touchscreen starship controls. lucked into that future when a local company offered him an industrial 42″ multitouch PC that they were throwing out. But larger and more modern incarnations like this one have the potential to change how we interface with technology on a daily basis.Ĭontinue reading “Building A Cyberpunk Multi-Touch Input Device” → Posted in LED Hacks, Peripherals Hacks, Raspberry Pi Tagged input device, multitouch, opencv, RGB LED, touch panel The camera’s field of view unfortunately means the box the panel gets mounted to has to be fairly deep, but if recessed into the surface of a desk, we think it could look incredible.Ĭustom multi-touch panels have been a favorite project of hackers for years now, and we’ve got examples going all the way back to the old black and white days. His code will even pick up on specific gestures, like a three finger drag which changes the colors of the LEDs accordingly in the video below. To turn this into a viable input device, is using a Raspberry Pi and its camera module to track the number and position of fingertips from the other side of the acrylic with Python and OpenCV. There’s plenty of interesting applications for such a gadget, but it’s not going to be terribly useful attached to your computer. But ultimately, it would just be a glorified button. With RGB LED strips added to the edges, you could actually stop here and have yourself a very cool looking illuminated touch sensitive panel. This is attached to a capacitive sensor module so it’ll fire off whenever somebody puts a finger on the plastic. Bare wires are then laid inside the grooves, secured with a healthy application of CA glue, and soldered together to make one large conductive array. Though if you do have access to some kind of CNC router, this would be a perfect time to break it out. The build starts with a sheet of acrylic, which has a grid pattern etched into it using nothing more exotic than a knife and a ruler. This multi-touch touch panel built by might look like it came from the retro-futuristic worlds of Blade Runner or Alien, but thanks to a detailed build video and a fairly short list of required parts, it could be your next weekend project.
