Question: Is this projector compatible with the kindle fire 1st or 2nd generations? If yes, which adapter?
Document: UPDATE, Sep. 19, 2013: Nearly a year after this review, the iPad streaming still works, but has become a bit glitchy. I'm chalking it up to iOS 7 (I'm now getting warnings that the Apple HDMI adapter is not compatible). See the comments thread for some information about how I still manage to get iPad streaming to work with this projector.
The sound is adequate too, especially since they're only a few feet away from the projector.It really is a fun item, but is it worth 300? If you'll use it for its portability and ease in watching a movie anywhere, then yes it is worth it. If you are a TV/video person that is a stickler for HDMI or other high quality viewing and sound then you might want to skip this. For what it is, it's fun and works flawlessly with minimal troubleshooting, if any.
Come on people this thing if pretty damn cool. Yes it's not the highest res projector you can buy, but for a couple hundred bucks, something that is completely wireless and portable it's pretty amazing. This thing fits in the palm of my hand and the image it projects is very watchable. I made the audio wireless too by adding a little bluetooth transmitter dongle that I bought on here for $20.
You can project onto any wall, but you've got to find a leveled surface at just the right height for the projector to sit on. I think the projector by itself would be a good companion to an iPhone or iPad with an adapter cable. Together with the Roku stick the 3M projector's a neat toy, but just a toy.
What a great little projector. Set it up on a tripod and shot it on an bare white wall and I'm thrilled. Yes it's a small projector and it doesn't have the performance of its big brothers and sisters, but it does the job quite nicely. Last power failure was pretty good test since we could watch movies via a laptop. I was also a first time user of Roku and have since purchased the Roku 3 for my big screen.
Walls don't have to be freshly painted white to see the video, everywhere I go in America there's a suitable wall to project on. Wifi is everywhere if you're not sure how to get onto the Internet, then yes this projector may not be for you. Can you watch the entire first season of Game of Thrones on the original battery charge? Probably not.This projector will not hold your hand but it does what it promises. Will the picture be as sharp as a brand new 4K tv from Best Buy?
Also before i used it for the first time it had to update the Roku device - 43 minutes!!! (this was on a N wifi connection)  A convenient workaround, assuming it's plugged in, is to turn of the projector (with the lightbulb icon on the remote) when you're not using it rather than shutting it down.Will anyone come out with an adapter that will allow this to be used with older TVs?
The image is crisp, clear, and clean - provided that the picture settings and focus wheel have been properly adjusted. It comes with a handy remote, and power adapter. What's more, the projector is actually mobile and will hold a charge... just in case one ends up in the wilderness.The product description claims it has the ability to project up to 120", and this is definitely accurate.
So for those of you planning to use a VGA port to connect your computer to this projector you're going to have to buy an adapter first. Other than that the projector is a good investment.Things to note:One HDMI portDoes not work in bright rooms. Best image quality comes from a dark room.Image size can get up to 10 feet and still maintain good qualityFrame rate is great.
I got these and, together with the cables I got, they work great with no buzzing.Everydaysource Gold-Plated 1 / 4 Audio to 1 / 8 Audio M / F Adapter, 6 Packs($six and thirty, with shipping):B00DDK6P3K3. You will also need quality male-to-male audio cables, one for each speaker and one for from the projector to the amp.
Answer: The Kindle Fire HD has a micro HDMI output (non HD Fire does not).  I think you'd need an adapter to make it work, though they are cheap (few bucks).  Something like this I think would work: HDMI to Micro HDMI F/M Adapter
