I'm going to guess that this "projector" will give you maybe 20 lumens - if you're lucky, which means it's invisible unless the room is completely dark and there is no other source of light to wash out the image.

And your projector must be at most 2 or 3 feet from the projection surface.

/Used to use a 50 lumen projector - that was hard enough to use in a room that had some light keeping in from the outside street lights even though I had blackout curtains.

It's our only hope.

Just make your entire house out of that newly discovered "darkest substance ever".  Surely that's cheaper than buying a decent projector that works.

Basically acme here to say this. Mr. Inverse Square Law calls shenanigans.

Also, $27 for a cardboard box and some (likely plastic) lenses? It's amazing what some people would rather have than money...

How many megapixels does it have?  That's what I really need to know.

I have recently entered the 21st Century and got my first smartphone (Droid Razor). I know I can get a Bluetooth keyboard for it, is there anything I can plug into it to get a bigger screen to work with? I'm a former Palm Pilot Geek that used a Palm TX like a laptop, for almost everything except a phone. Very handy and compact for my almost continuous travel. It did everything, MS Office, mp3 music, mp4 movies, surfed the web, used a folding IR keyboard, etc. I'd like to use the Droid as a laptop substitue as well.

Many Android phones come with a mini HDMI port out (but that isn't really handy while traveling), and some of them have a laptop-like accessory as well, but those were rarely worth the $300 price range or so they were offered at, since they didn't offer a whole lot other than "make the phone screen bigger!". So, most of them really can't be used as a substitute unless you spend hundreds of additional dollars in accessories.

If you're happy with Android but would like something that could easily pair with it and accommodate your needs, I would recommend getting an Asus Transformer tablet. The prices range from $200 for used older models, to $800 for the top-of-the-line stuff. They function as a tablet that has a detachable keyboard/trackpad accessory that also happens to give you USB ports, additional memory card expansion and doubles the battery life. I've had mine for a couple of years now (an original TF101), and it works fairly well.

Here is one of the lower-priced ones, but by no means does that mean it can't handle Office documents, music, movies, etc.

This post suggests you have a microHDMI port (others use the microUSB for video out, see "MHL").  You can get a micro-to-regular for <$10 which should suit your needs.

Newer devices can use Wifi Display or the like.

Everything you sai, but just to add, those droid netbook adaptors have been discontinued and are no longer supported, that said, they still work with the droid phones but nothing is being updated. They can be ffound as new old stock here and there for as low as $50 if you look hard enough

as for the thing in the article? Its a black box frenzel lens device. Like a camera obscura. It will only ever be as bright as the device producing the image.
It's not useless, just not as useful as the article may claim. If your device has HDMI out, you are better off using that with a real projector

It doesn't seem to have its own power, so it seems it uses mirros and the lens is simply a magnifier for your screen. I.e., it's lumen output is whatever your phone is doing.
/could be wrong, but it really does look like a simple cardboard box with a lens.

From what I have seen the cheap MHL adapters dont work with anything newer than the Galaxy S2.

It could be amusing to make something like this out of parts. Ill maybe give it a go and let you know how it works. Going to need a REAL dark room

£16 for a cardboard box that at best technically will perform as advertised. FFS. It's a nice looking cardboard box at least. Looking around I do see pocket sized projectors that promise 85 lumens. Granted they seem to cost at least £120 but I expect it might be a bit more suitable to purpose.

All the above. I still have a working droid bionic with lapdock, desk dock, and car dock accessories. Current phone is an s4 active with mhl. The desk dock it works with is goofy, only works in portrait mode, with phone tilted because of the port cover. An mhl/usb/hdmi cable works better for landscape displays, but the usb part is only for power, so input devs need to be bluetooth.

Z-clipped: How many megapixels does it have?  That's what I really need to know.


If it has less than 8 MP I don't want it. I mean, who'd want to watch full HD video with such a crappy projector?

This is a neat science project for middle schoolers studying optics.
