Video Projector
I saw a mini video projector £99
display your dvds, satellite, computor or any other video source project the picture on your wall no bulbs its all done with LED s it said get a screen size of up to 21 inches which I was a bit disappointed in But I thought, could this be the future ? the tv arial going straight into a projector no need for bulky TV sets just project the TV, Sat , DVD etc straight onto the wall ! plug in a couple of speakers and Bingo ! Instead of a poxy computor monitor, surf with the (hot ) pics projected onto your wall 6ft x 5ft ( well eventually ) Anyone had a go at this technology ? (it mentioned satellite, but not the terrestrial tv signal .. wonder why not ? ) |

Sounds like a gimmick/novelty to me, I doubt the picture quality would be up to much, not for serious viewing anyway.
Projectors like this though on a bigger scale are and have been capable of displaying images from TV, DVD, Sat, VCR, PC etc for ages, yes you need the source connected to the PJ to get the images but they can project the image on a wall from anywhere from 20" -> 200"/300". The downside to projectors is the limited lifespan of the bulbs, 2000/3000hrs before they need replacing, some are rather expensive to replace - £200/£300. They also need to run in complete darkness to get the best out of them. PJ's are great for special screenings but not really ideal for everyday viewing. They are becoming very popular these days but they are still a niche market. The one I own is very compact, it fits on the palm of my hand and only ways a few pound. I wouldn't have called today's flat panel LCD/Plasma bulky.

but this one in the advert is led not bulbs
and the blurb stated that it has to be 1 metre away from the screen with max screen size of 21 inches so at £100 it is really I suppose a bit of a novelty and only works on a small scale. But the idea is great and its possible that the technology will improve this one claims to give 10.000 hours of use (which is a long time in any language) and it is low on power consumption |

it just says mini video projector
screen size up to 21 inches from dist of 1 metre I suppose it will work further back and give a bigger pic though I dare say the quality will go down the bigger the pic it looks more like the pic in the 2nd link but the lens is off on the right hand side at 99 squid a lot will buy it and give it a go but Im wondering why it said sat .. dvd ... satellite or any video source but no mention of TV or free view which is what most people will want to plug in ( I saw it in the Maplin catalogue ) |

Also if it had a TV tuner (analogue or digital) then it attracts a higher import tariff.
Proper projectors aren't that much more money new. As a rough guide have a look at Ivojo and search the £0-£499 category. There's stuff for less than £250 that would make a reasonable job of showing video/dvd/consoles on a 5 or 6ft screen. Certainly more than good enough for most people only interested in a big screen "wow" rather that absolute fidelity. ![]() These LED projectors are interesting because they have the potential for long life and low heat output which would do away with the need for noisy fans. The technology has been used successfully in the business market to make tiny pocket sized projectors for business travellers. The Achilles Heel is light output. LEDs don't generate anything like the intensity of light of a UHP lamp, so that's why a £99 LED projector maxes out at 21", and even then I would guess it'll need a darkened room before it starts to give a watchable image. It's a novelty and if some has £99 to waste then why not.

This one? http://www.maplin.co.uk/Module.aspx?...25585&T=Module It does mention TV. ![]() Quote:
Are you limited to space in your bedroom or cannot hang a flat screen TV on your wall. The answer therefore is this compact video projector. Great for watching regular TV, DVDs even for playing games and all from a unit that''s low in power, small in size and has no lamps or bulbs that can blow.
As with most PJ's you have to connect the source directly to them.Nice idea but 21" screen.

This from the download section for that product... Quote:
Technical Specifications It's no wonder that 21" is the max screen size. As you would expect for £99, the projector's resolution is way short fo what is really needed for PAL (720H x 576V).
Light Source: LED Luminous Flux: 13 Lumens (equivalent to general 400 Lumens) Resolution: 557H x 234V or 480H x 240V ... Speaker: 2 x 2W Video Connection: 3.5mm Jack Socket (Adapted to 1 x Composite Video RCA and 2 x Audio RCA with Lead Included) |

yeah I have to agree. Its a nice idea but a 21" screen is nothing these days. Also someone said about it being full HD. but the blurb only mentiones a RCA composite input.

YES you want the projector to be behind
you as you watch so we are talking of at least 6 feet between projector and screen The optimum for this mini projector is 1 metre ! so whats the point ? But as technology advances and prices fall these projectors could become very popularand give a really "night at the movies" feel to watching TV |

There is a prototype full 1080p HD projector from Delta in one of Deacon's links. It's more of a statement of intent rather than something likely to be launched soon though. There's also no mention of price - another indication of it being vapour-ware rather than a realistic commercial proposition for the near future. |

Loads of full 1080p projectors exist already - if you have the budget for something "professional" then look at this;

The optimum for this mini projector is 1 metre ! so whats the point ? Most proper projectors of this type have very short-throw lenses so they can produce a big picture at a short distance; a 6ft wide image or bigger at just 2m throw isn't uncommon.This Maplin jobbie has a very long-throw lens; something like 6:1! But because the light output and resolution are so low the projector can only produce a 21" diagonal image. There's no zoom, so I'd guess the 21" image size recommendation is where the lens has best focus. |

i suppose Im thinking of the old slide projectors, they were a pain because of all the setting up of screens
(and getting everything down from the attic ) But the images were so intense and it was a great way of looking at photos the darkness seeming to focus the intensity of the images. But those projectors had powerful lamps maybe LEDs will never get to that intensity but.. who knows ? |

Slide projectors also had/have much greater resolution too; even the very budgety ones. Something sadly lacking from our £99 friend from Maplin
![]() There's a market for most things provided it meets a need for someone out there. Who would have predicted the success of Nintendo Wii when the gaming market appeared to be dominated by the uber-resolution consoles. Perhaps there's hundreds or even thousands of folk out there just dying to sit in a darkened room watching a 21" projected image of pretty crappy image resolution but happy as Larry because it only cost them £99

Anybody know if you can get one of these with a bigger picture than the rather small 21inch? I want a projector but am put off by the cost of bulbs.

You get around 3000hrs on low power, use the PJ for special screenings I doubt bulb life would come into the equation, you'd upgrade the unit before it wanted replacing. The 700x is about £370, for a 720p HD projector that's a bargain. |

Back to the original topic, though 21 inches seems small for a projector, thats only at 1 metres. According to this site: http://nuigroup.com/forums/viewthread/3479/
It's 21-inch at 1m distance, 40-inch at 2m, 53-inch at 3m and up to 80 inches Id consider that a bargain. |

It only has very limited resolution, only 240H, limited brightness, 13 Lumens - I doubt you will be able to make out what the image is at 40".
