Movie Mover: A Mobile Theater

[Electricunicycle] put together this radio controlled mobile theater system to amuse his neighborhood pals. It is a projector and what looks like an electric wheelchair base. He has managed to fit a decent sound system in there as well, which required a second battery. This is pretty cool, though we could see ruggedizing it a little more to be able to drive around in fields. He states “this is one of the faster movie theaters around”. This makes us wonder what the competition is like.

Slide Digitizer

December 1, 2009 by 24 Comments

Remember slide shows? The ones that used a carousel projector and real slides? [Brian] wanted to bring his slides into the digital age but was spending far too much time scanning in the 35mm relics. He set to work and built a rapid slide digitizer using a projector, a DSLR, and a microcontroller.

His system centers around an AVR microprocessor, the ATtiny2313. Some DIP switches are used to set the number of slides to be scanned, and the timing for synchronizing the projector and the camera. Using two relays, the cable release for the DSLR and the remote advance pins on the slide projector are connected to the AVR. [Brian] used a macro lens and sets the focus, exposure, and f-stop manual. Once everything looks good the touch of a button quickly steps through the entire carousel at about 1 slide per second. A small video of the process is embedded after the break and his writeup has some comparison photos between a slide scanner and this setup.

Haptic Halluc 2

We can not express the childlike glee that we experienced watching this video. We want so badly to have one of these setups. What you are seeing is a half dome projected cockpit with two haptic controllers in the style of a delta robot. This is controlling the Halluc robot which is a hybrid wheeled octopod. The dome can and has been done at home fairly simply, and we suspect that you guys could come up with some similar delta controllers. So who wants to build one and donate it to hackaday?

Nikon Coolpix S1000pj (teardown)

HAD_NCP

Earlier this year, Nikon released the Coolpix S1000pj, a 12 megapixel point and shoot with the usual features, including image stabilization, face recognition, etc. However, the S1000pj features a built in projector into the usual diminutive point and shoot footprint, and also comes with a remote for controlling the projector in display mode, or for remote shooting. iFixit has gotten a hold of the unit, and detailed the difficult teardown process, which included component desoldering to get the extremely compact system completely apart. It is also interesting to compare this setup to other stand alone pico-projectors we have covered.

Wacom Light Graffiti

[Jon] wanted to have some fun with the Graffiti Research Lab’s LASER Tag. Unfortunately his computer wasn’t quite up for the challenge of detecting the laser pointer with a webcam. Not to be discouraged by this hardware limitation, he purchased a used Wacom tablet and threw together some code to make it work with the GRL display software. Now designs can be scrawled on the pad and the projector displays them with the familiar dripping paint effect. Continue reading “Wacom Light Graffiti” →

Portable Large Interactive Display

[HyPe] over at the Natural User Interface Group developed this concept as part of his Master’s Degree in Industrial Design. This suitcase sized projector and computer allows people to have a 60″ multitouch screen available wherever there is a large enough surface.  The current software is designed for ad-hoc meetings about large-scale construction plans. The rolling case includes a short-throw projector and webcam. Just set it on top of your work surface, lift the lid, and it’s ready to go.

Things To Hack: Sub 100$ Toy Night Vision, Projector, And Tv Game

Ars Technica writes about three new toys coming out this year: a sub 100$ projector, tv game, and night vision goggles. The projector runs at standard TV resolution, takes standard composite in, and outputs an okay picture. The night vision goggles are monocular but focus both eyes on a single RGB LCD. The goggles uses an array of IR LEDs instead of amplifying ambient light to see in the dark. Lastly, they have a standalone implementation of the arcade game Big Game Hunters. The rifle uses a sensor bar to do the motion tracking and features a 32MB rom to hold the game files.
