Main research for the construction of both projectors I have built thus far was obtained from the DIY Audio Forum and the many projectors there , in particular the fantastic work done by fellow Aussie Ace_3000
I have decided not to add pictures etc... of my first projector to this site, allthough the images it produced were excellent it did have overheating issues as a result I constructed the following projector I have named ' The Retro ' to overcome this problem. If anyone is interested in viewing my first projector they can see it on my thread at DIY Audio
Living in Australia does make it more costly building a projector most of the components required must be sourced from overseas if you wish to use the best optics. Alternatively optics can be obtained from an old overhead projector which can be picked up extremely cheaply on ebay (under 100 bucks) or from swap meets or garage sales etc...

Once all the materials and components were obtained I began construction. I decided on MDF for the box reinforced with 10mm angle on all joints. 1mm aluminium was used for light unit, ducting and heat shields.
