This Instructable is for a prototype homemade projector that can be illuminated by any decent LED flashlight/floodlight.
This is my first published instructable so please leave comments and/or suggestions! Any feedback is very welcome and I will try to respond to everyone as soon as I see it!
At this stage the iTorch is a kit that I hope to be able to make available if I were to somehow get my hands on my own laser cutter. I have been spending a good amount of money using school equipment to laser cut this project, and got a quote to use the 3d printer and the price was astronomical. So needless to say a laser cutter and 3d printer would go to good use and be greatly appreciated.
Though you could probably reverse engineer one of your own. ;)
I designed the iTorch to be a portable and wireless projection system that would allow a user to freely project their media wherever they choose. I am currently working on integrating the iTorch into a gaming platform where the iTorch is both the viewing device (tv) as well as the controller!
The concept for the iTorch came from trying to find a financial solution for another larger scale project I had been working on. A interactive and holographic environment that would have required the use of several costly projection systems.
However financing the project has been an issue. So I tried to redesign the installation on a smaller scale. Though a small scale solution may have conveyed the idea, it would not have allowed anyone to have the full experience.
I needed projectors, and they aren't cheap, so I thought I would build my own.
In creating these projectors I came up with the idea for a portable battery powered projector that was illuminated by the power of a flashlight.
From personal experience with projection, and researching the purchase of several projector units I found that the main issue for projector longevity were their bulbs. The light bulb in a projector seems to be the most common part to break or burn out in the life of a projector, but with the iTorch - if you have another flashlight you are good to go!
The iTorch design was created and built by Travis Higgins for a capstone project in New Media at the University of Maine. In development of virtual reality shared experiences (shared augmented reality). The iTorch was designed to be a portable and wireless projection system that would allow a user to freely project their media ( or augmented data) wherever they choose.
This Instructable does require a little bit of technical skill (disassembling LED screen) and if you are trying to build it from scratch it will take a little bit of math and access to a fabrication lab.
It takes an hour to cut the wood into a kit in the laser cutter. I use a 4' x 2' piece of Birch that I cut down to 24" x 18" to fit the laser bed. It's $10 a sheet at Home Depot, and costs $10/hr to use the laser cutter.
I've been using aluminum foil from my kitchen for the reflective siding in the light box. So I don't count that.
The Flashlight cost around 50$ + $40 for the batteries and charger I believe. Those can vary.
The 12V fans I get at RadioShack for $16 today, I think they were on sale the first time I went. You can get the male to male couplers there too for about $6-7. I also get the 5V USB rechargeable power bricks there too insanely cheap, usually on sale, today I got one for 4$.
The LCD panel is a 2.0'' TFT from Adafruit at a hefty 45$.
Raspberry Pi at a lovely $35.
SD card 10-20$
So here are the parts you will need to build your own iTorch!
(1)- iTorch assembly kit - (coming soon!)
- Main Body Assembly (body,lcdholder, lens holder)
- Flashlight Holder Assembly (varies depending on flashlight type, for this 'able I'm using the 'SuperBright')
- Raspberry Pi Assembly
(1) Flashlight - For this instructable we are using the SuperBright LED flashlight. - $45-50 + batteries
(1)- Raspberry Pi model B - http://www.element14.com/community/community/raspb... $35
(1) - USB bluetooth & wifi combo - $20ish
(1) - USB storage flashdrive - $10-20
*(1) - SD card for RPi OS or multiple RPi OS's - $10 - 20
