Previously I posted instructable on how to make LED HD
projector that you can see here- instructables.com/id/DIY-LED-PROJECTOR

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
ebay.in @ 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.

Box ka kya size chahiye ?? Apke lenses ki size kya hain ?
380×180×130 inside measurements outside it depends on plywood thickness

<p>Dear Kehal Doshi,</p><p>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 &quot;45-50&quot; inch screen yours is 100&quot; 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.</p><p>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. </p><p>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 wraglan@gmail.com I'll buy your product by ur handmade through cash on delivery.</p><p>Don't mind if I asked u some idiotic questions if it is I apologize for it. <br></p>
Hi,<br><br>Can you send me all staps and equipment which i have to use for the projector on my email khan.ahtsham@gmail.com
Can you please mail me the whole instructions/program at anirudhkurhade@gmail.com
<p>Hi Kehal,</p><p>I have gone through both the instructable. Both look good and amazing. However, if you see the cost of the Second box with all the accessories mentioned/recommended - its coming around not less than INR 22,500 ($ 370). </p><p>The New Branded Compact Projector in the market starts from 30K (you only mentioned that). What is it in this DIY PJ, that is worth making it at 22K (or more if something goes wrong). </p><p>Also, what is the projected life of this PJ? What is the continuous running Time? </p><p>Moreover, the instructions are not step-by-step. Looks like you are marketing the stuffs, that are available on Ebay under Globalibay (http://stores.ebay.in/globalibay/).</p><p>Hope you will clarify and help members follow it correctly. Thanks for your efforts. </p>

<p>really nice effort. and good post. your new version looks more appealing. cheers!!</p><p>I m going to make mine very soon (have added all the materials in my ebay cart, just need to click on buy button. ;) ) </p><p>Although I have few queries, would be really happy if you can answer them.</p><p>1. how did u corrected the keystone in the new version, you haven't given any instructions in this post. </p><p>2. as you said this new version is brighter, did you do any tweaks with the original source or bought a more powerful source? </p><p>3. can we have a demo of the lcd screen assembling and its controls as in brightness or colour correction and the inputs. Is it the best or are there any flaws? </p><p>4. Also does LED light source fade in time? How much time has passed since you made this? Is it still functioning the way it should. Are there any heating issues? </p><p>Too may questions to you to ask, but these are the primary ones. :)</p>
Hi.<br>Do you have the same triplet lens with version 1?<br>Thank you... ;)
Yes I used almost same components that used in previous version.
I ask because in some foto I think that you have other triplet.<br>Thanks...
