Diy Projector

tb1012

so i have made a shoe box type Projector using my phone, magnifying glass, and magnifying sheet. it works if i use a pitch black room but can be improved on. i have a old portable dvd player that does not work so i salvaged the 6.2 screen to use. also will get a raspberry pi to use with the screen and LED light. i have seen other videos on how to go about this but im sure Ben could do a much better job at it image  also still waiting to see him make a Pip boy image

  • I have also made a shoe box projector and know the grief you have with it. My second try at a projector I used a old overhead projector a local school was selling, a small 10 inche hdmil capable tv I found on banggood, and a PI. Brighter, but so much more balky.  I used it a couple of time to run a portable drive in theater for family and friends. I need to shrink it down to make it more portable. I used a small gas generator to power the projector, PI, and my hot air popcorn maker. I used a modified fm transmitter plugged into the PI's audio jack to transmit the sound. This year I am going to try and use the Pi' to transmit sound using the pirate radio station hack that Make.com has posted.

     

    Maybe Ben can help us both out with a design we can follow.

    ya i would like to get my hands on a overhead projector just for parts tho. but the goal for me is to make it as cheap as possible and small. also maybe have it battery powered and the fm transmitter is a good idea too

    Same here, smaller the better. Battery power might not be able with my rig hence a battery powered rig would be great.
