[Lou] needed to mount his projector to finish up his home theater. But he was rather put off by the cost of commercial solutions. He ended up building his own projector mount for about ten bucks. The technique reuses some scrap metal and sources connectors from the hardware store. If your projector will be mounted [...]

[Michiel] gave us a little shout-out by drawing the Hackaday logo with his recently completed 16×8 pixel laser projector. It uses a spinning set of mirrors mounted at slightly different angles to redirect the path of the red laser diode. The projector is driven by an Arduino. To give it more than just a hard-coded [...]

There’s a certain mystique about old home movies and 8mm film; whether it’s footage from a family gathering from 40 years ago or a stop-motion animation you made when you were 12, there’s an immediacy for film that the VHS tapes from your family’s first camcorder can’t match. [Teslas Moustache] has been getting into 8mm cameras and [...]

[radicade] wanted to know what real life portals would look like; not something out of a game, but actual blue and orange portals on his living room wall. Short of building a portal gun, the only option available to [radicade] was simulating a pair of portals with a Kinect and a projector. One of the [...]

For a newborn, everything is magical; a lack of object permanence means everything is new, wonderful, and novel. What then, could be better than a projected star field circling an infant’s room, gently sending them to sleep? [Pete] was inspired by this earlier starlight projector that projects a rotating star field onto the walls and ceiling of [...]

DSLRs aside, the price of digital cameras these days can make it easy to consider just tossing your old one out when it breaks. [Leonidas Tolias] had another idea, and with a few broken cameras he had on hand he constructed a slick little pocket-sized projector. The project started out as a pair of lenses [...]

It’s Friday night and these guys are driving around town looking for a good spot to play a head-to-head game of Snake. It’s not that they need somewhere to sit (they travel with a couch and floor lamp for that purpose) it’s that they’re using a projector and camera to make a game out of [...]

Apparently, there’s some sort of sporting event being televised this weekend that has been historically used as an excuse to buy a big-screen TV. [Joel] wanted a huge-screen TV on the cheap, so he converted an overhead projector to something he can use with his XBox. Using a bare LCD panel with an overhead projector is [...]

If you’re going to build a giant touch screen, why not use an OS that is designed for touch interfaces, like Android? [Colin] had the same idea, so he connected his phone to a projector and a Kinect. Video is carried from [Colin]‘s Galaxy Nexus to the projector via an MHL connection. Getting the Kinect to [...]

No matter how good the intentions or how strong your hack-fu may be, sometimes you just can’t cross the finish line with every project. Here’s one that we hate to see go unfinished, but it’s obvious that a ton of work already went into reclaiming these smart white-board projectors and it’s time to cut the [...]

In case you missed them the first time around, here are our most popular posts from the past week: In the #1 spot, we had a post about a tri-color laser projector that really is a well-done project. This projector sweeps the lasers around in vector mode using a pair or mirror galvanometers so would [...]

Who hasn’t thought about turning a 1950s slide projector into a digital projector? [Matt] did, but unlike most of us, he actually did it. [Matt]‘s friend [Angus] found an old, single-slide, sans-carousel slide projector in the trash. It’s a wonderful piece of ancient technology with a fabric insulated power cord and bakelite lamp socket. This [...]

After futzing around with a cheap pico projector, a webcam and a little bit of software, [Jas Strong] built herself a 3d scanner. In spite of the dozens of Kinect-based scanner projects, we’ve seen structured light 3d scanners before. This method of volumetric scanning projects a series of gradient images onto a subject. A camera [...]

This hack is not for photographers with weak hearts. We’re going to be talking about destroying the body of a Single-Lens Reflex camera. But out of destruction comes something new. A broken camera paired with a flash and functional optics can be used to project light patterns for picture backgrounds. The hardware is often referred to as [...]

It always blows our mind to see the things that people dream up when playing with Lego. Given enough time, you could likely replicate almost any mechanical device with the right amount and type of blocks. [Friedemann Wachsmuth] recently wrapped up construction on a very impressive Super-8 movie projector with the help of his friend [...]

[Jon Howell] came up with what he calls a gratuitous project which projects his name on his office door. The thing is, his office door slides on tracks so he made a projector that can follow the movement of that screen. He used a laser printer to make a black and white pattern that indexes the movement [...]

There’s a pretty good chance that you already have everything needed to make this image projector. We thought that yesterday’s video projector was simple, but this one makes it look like a super-computer in comparison. [Esrun] grabbed a flood light, some transparency film, and a common magnifying glass for use in his still-image project. This [...]

Here’s a video projector that [Matt] hacked together. He needed a small and inexpensive solution to use with his R2D2 build. As you can see in the video after the break, it has no problem playing back the Princess’ distress call. But even if R2D2 is not one of the droids you’re looking for, we think [...]

[Don't stop the clock] is doing some work with a projector, a camera, and the Kinect. What he’s accomplished is quite impressive, combining the three to manipulate light with your body. The image above is a safer rendition of the Hadouken from the Street Fighter video games, throwing light across the room instead of fire. [...]

[Raj Sodhi] and [Brett Jones] have been working on interactive augmented reality as part of their research at the University of Illinois. What they have come up with is a stylus-based input system that can use physical objects to create a virtual landscape. Above you can see that an environment was built using white blocks. [...]

[Socket7] got his hands on a projector that had some color calibration problems. Of course the servicing manual says that there are no technician serviceable parts inside, but he cracked it open and fixed it anyway. This is an Epson PowerLite 5500c which was showing blue and yellow bands around the outside of the projected image. He [...]

This laser message scroller is built with inexpensive parts. The heart of [Raul's] system is a spinning pill-box with eight mirrors on it. Each redirects the laser to a different vertical portion of the projection surface. There are eight small arms on the apparatus that each break the beam of an optical sensors as it [...]

[Jarrod] sent us a link to this home-built laser projector after seeing a different projector that we featured yesterday. This system is fundamentally different. [ChaN], who finished the project several years ago, didn’t use a loudspeaker to move the mirrors, but instead build his own closed-loop Galvanometers. Two of these are controlled by an ATmega64 to [...]

This computer can be mounted in any standard light bulb socket. It uses a pico projector combined with a camera to generate a touch display wherever you shine it. The photo above and the video after the break show the bulb in a motorized lamp arm but that’s just smoke and mirrors, the bulb itself [...]

This iPad dock is a well-executed gaming accessory. [Linkreincarnate] used a Hori Wii fighting stick as the controller. In his hardware explanation he outlines several benefits of this choice including built-in support in most of the iPad emulators, as well as foregoing the need for a wired connection. Just above the controls there is a standard [...]

This video shows a demonstration of Bonfire, an additional interface for computers. It consists of a pico projector and camera hang on the back of either side of a laptop. The projector displays information on the table top and the camera monitors the area for interaction. It can recognize your hand or objects such as [...]

Being hackers, sometimes we just want to hack something together, not engineer it. This projector is a great example. Made mostly out of cardboard and duct tape (or duck tape if you prefer). He picked up a 12v LED array, a cheap fresnel lens, an LCD from a “back up monitor” and a focusing lens [...]

Reader [Jan] came across a website all about building your own video projector. We’ve linked to five of the best projects for 2010 but there’s a ton more information if you dig a little deeper. Our favorite so far is the GohtanBox v3 and it’s giant LED panel that serves as the projection light.
