DIY LED Projector V 2.0


Introduction: DIY LED Projector V 2.0

Previously I posted instructable on how to make LED HD
projector that you can see here-

This was my first attempt to make projector then I more improve it and add many other features.

So I upgraded my projector. Many new features I added in this version that was needed for professional look.

What’s New –

1. Keystone correction feature added.

2. Now my projector more brighter.

3. New box design looks smaller.

4. Add internal speaker.

5. Add relay module for auto on/off LED light with my LCD remote.

6. Batter box finishing look like company product.

7. Add new menus buttons.

Step 1: How to Add Relay Module?

I bought 5v relay module from @ 190 /- INR. I connect it with my 5v lcd controller pan drive power source and output terminal (COM and NO) connected with LED light driver and 240v power source. Now when I on my LCD controller with my remote the relay get triggered and LED light on automatically.

Step 2: How Setup All Things ?

Step 3: Finshing

I use rexine for finishing touch which is use for making seat covers.

Step 4: Results in Completely Dark Room

Results In Completely Dark Room From 10 Feet Distance and Image Size Approx 100 Inch diagonally.

Dear Kehal Doshi,

My self Sekar from Chennai (Tamil Nadu) for the very long time onwards am planning to buy projector at low cost but i can't and finally i have seen urDIY LED PROJECTOR V2.0 video on youtube am very much impressed actually my room size is 11.5*10 sqft so i planned "45-50" inch screen yours is 100" inch so i decided to buy ur projector why should i get buy all stuff and to fix it by myself it's waste of time and i don't have such knowledge too better this way is good.

But i have a question for u, if i buy this projector how long will i use it for a day bcoz right now i have attached my 32'inch LED TV to my PC so i use it for 15hrs a day some times it would be 18hrs too. I'll come to the point that's the way, can i use your projector as my pc display if it is possible can you tell me how long time will it work.

Basically in the market the projectors lamp will give 2000 - 6000 hrs so like that in ur projector how long will it work. pls mail me your answers to this id I'll buy your product by ur handmade through cash on delivery.

Don't mind if I asked u some idiotic questions if it is I apologize for it.
