1.direct orginal image(not projected)..
2.projected and captured by camera..b101 128w 15k lum led..brightness contrast low setting..looking nice
3.projected and captured by camera..n070 98w led 10k lum..brightness,contrast high setting..so washed out..

this is another diy builder Mr kamal's pj from india
he is also a fm of this forum
posting his shots with his permission.

it is a full HD one.since FUll hd lcds less than 10 inch are very expensive this is a 10 incher lcd build..
so a litle centre to corner uneven light is there like mine..

the friend who bought one of my pj,changed his apartment..
just see the how quality changed when the screen changes
prvs screen was light greeen dirty wall
present one is flat white new fresh..
and photos taken in daytime..you can see the leaked light..

even its better tha my present 128w pj..as my screen is chuna wall...huhu..
need screen soon

 

[prosenjit]

they are 1.5 times more powerful(in lumen)...in a chuna wall..

and now see same image in less powerful pj but in a good wall

screen playes a big role

35K..including main parts,import duty& shipping,local parts etc..

main advantage 24*7 use..and self service..
pq..right in front of you..

disadvantage
no ceiling mount..wooden box is heavy..
no 3d yet

 

[koushik]

Prosenjit, more details please about the projector. Like LED or Bulb etc etc ... resolution and all ... Please ..

 

[prosenjit]

LED 128w
1280*800 reso..
needs dark room(this is also a disadvantage)

 

[harshi_n]

Sir... This is Soumya majhi , From Baruipara [ 20min away from Singur * hope you understand my Location afterall Singur is famous now ]

I already made a Diy Projector
15" Screen 1366 x 768 px [Acer P166HQL 15.6-inch]
100w Led from Ebay
Fresnel lens 400x320mm f220mm - From optolife.com china
Fresnel lens 400x320mm f330mm - Same
Projection lens f317mm - Same

and I normally project image 114" from 9ft distance from the screen , And its pity much viewable in dark room

My Problem is ..the image is excellent in the middle portion but at the corner and topmost and bottommost it not that much crisp and bright as in middle ..
I heard if i use a condenser lens then it would be be great and corner will be much more bright ... Please guide me what should I do for projecting more adorable projection...
I am thinking of buying []DIY Projector Rectangular Aspheric Condenser Lens FOR Bulb Setup | eBay Item...
Please guide me... Waiting for your next positive reply....
Regards
Soumya Majhi

Guys, some excellent DIY Projectors show cased here. I just have a small doubt. Nowadays, FUll HD mobile LCD screens are very cheap and comes in size of 5-6 inches. Can that be used for a projector set up ? Will it not make the entire build smaller ?

 

[prosenjit]

gp you are very correct,the small screens used in tabs and cell phones are these lcd screens we use in diy pj...
now case is a good controller and transmissiveness check..and price..
in diyprojectorphils..you will find some 4 to 5 samples which are tested succsessfully..my screen is one of them..a 720p 5.6 inch screen alongwith a great controller is also avilable in that site..some members have built pjs with that screeen successfully
