Conclusion



Conclusion

Total cost came around 8000/-

Built time was around 2 weeks. Basically was waiting for an LCD panel which luckily got sourced. So decided to built this. All credits goes to Lumenlab forums(the pioneer). Some of the guide is an extract from same. Lumenlab also provides custom Fresnel lenses which needs to be ordered from them.

Results are very much satisfactory. The design can be made much more better. Best part is the project is fun and you get to know much doing it. Many other modifications has been made by others.

Always practice safety first and good luck.

Great stuff there dude!!!! infact if you could add fins to the aluminium reflector, it will aid the cooling of the enclosure.

Also, whats your take on putting a LCD above the normal slide projector and using that for projection?? dont have to mess around with the whole lens and distance issue??? just change the lamp to a white colored one, and give it adequate cooling???

If u can manage to get a normal OHP and mod it its very much possible but u need to source same. Another thing is the cooling should be very much optimized if you are getting an OHP and the i doubt you can use the 400w in that one cause the lamp itself is quite large and everything the lens center, triplet center, lcd center and lamp arc should be in one axis.

LCD Overhead Projector

this was what i had in mind.. your idea is surely more accurate and crisper in the picture reproduction, i am sure, and it would be brighter as well.. Just thinking about this, coz i have a giant wall waiting in the hall.. maybe use it for movie screening!!!!
