content: G'dayThis is actually my first post. I signed up to find out what the EEVBlog community thinks of the Mu Thermal Imager. I'm looking for some advice on whether or not it's legitimate or a scam. It is on a crowd funding website (Indiegogo).It's a thermal imaging camera that attaches to a smartphone (for processing and video display). Wavelength is 7 to 14 µm, at 190x120 resolution. The main plus is the price-point, it will retain for $300 eventually. However, the guy behind it (John McGrath) selling them (without a profit) for $150 as a promotional move on Indiegogo. Apparently his team is behind some NDAs preventing him from showing the actual prototype, so there's not much more than a few videos and rendered images.Anyway, here's a link to it[url=http://www.indiegogo.com/projects/mu-thermal-camera-a-great-health-diagnostic-tool?c=home]http://www.indiegogo.com/projects/mu-thermal-camera-a-great-health-diagnostic-tool?c=homeIt was also covered on Hackaday:http://hackaday.com/2013/03/06/a-real-thermal-imaging-camera-for-300/There is also a somewhat incomplete website for it:http://www.muoptics.com/So what's your opinion? Is this a great deal or is he going to run off with the money. Probably not considering the house he's in in one of the vids looks to be way more than just 200 000 (his goal on Indiegogo).I know most thermal imaging sensors at that resolution probably cost upwards of $300, so how's he able to get that and the optics, and every thing else into it for $150? Would you risk it for such a cheap thermal camera?~Josh

content: It does indeed appear to be a very impressive package for the money. I'm still a bit curious how they intend to interface it to both Android and iOS handsets, and what kind of compatibility it will have.How does Indiegogo work? Do you only get charged after the project is funded, or is it right away and you hope it shows up?

content: QuoteIt's set up as flexible funding, which means that all the money donated goes to the creator once the time is up (even if the goal isn't met, but I'm sure it will be though). I'm guessing that's when you're charged for it too. But yeah, you still do have to hope it shows up and he doesn't just take the funds and keeps them for himself.~Josh

content: Someone already proved it could be done for a low price and without special optics.http://rh-workshop-llc.myshopify.com/products/ir-blueThis Mu Thermal Camera uses a higher resolution chip, and does have some optics so it will cost a bit more.With that in the back of my mind I've singed up for a "Not So Early Adopters Special".

content: The IR-Blue is 64 zone, compared to 19,200. Thats a BIG difference.Also isn't the IR Blue a 'kit' at that price?

content: The problem with these projects is that making "stuff" is really expensive. You have parts cost, manufacturing costs, advertising, travel, trade shows, overhead (insurance, utilities, etc). not to mention paying the people who are working on the project.Most people who do not run a business in the industry in question do not understand all these costs... so they see a commercial product that sells for $100 and they think "hell, I can make that for $50! Then I can sell mine for $90 and make a ton of money!". But they don't know that the $100 product is sold by the manufacturer for $40, and the parts cost must be $10, and the manufacturer isn't making a lot of money even at those prices.Then the person with the idea starts a crowdsourced project, gets a lot of money... but because they do not have the experience or connections, they can't get the costs down like the big manufacturer can, and before they know it, they've blown half their money on traveling to various manufacturers trying to put the project together - and they don't even have enough left to cover the production run, even if they did it at cost.That is the big risk of these projects. I don't think it's really scammers trying to swindle people, but rather doe-eyed inexperienced neophytes who just do not have the knowledge or information they need to embark on such projects in a successful manner.Having said that, I know nothing about this project creator, nor do I know a lot about IR cameras. I own one (a FLIR i7) that was really expensive to buy... and I really like the technology and I know how it works. And what makes me nervous is that this guys claim that the expensive stuff is the processing and such, is totally untrue in my opinion. The expensive stuff is the optics and sensor. He is claiming to be able to make a camera for $150 that has the same resolution of a $2,0000 FLIR. That is over 90% cheaper. And considering FLIR is a huge company that has economies of scale (and purchasing power) this guy can't even dream of, it really makes me suspicious.On top of the erroneous claim that the stuff in the phone are the expensive parts, I would personally not invest.

content: True,Investing in this is a risk. Might as well be a Indiegogo april fools joke they have set up to get publicity.After some google-digging I've found this sensor: Mikrosens MS16070a. As well as a youtube movie of a movie shot with that sensor outdoors. The specs of the sensor match up with the specs of the Mµ Thermal Imager (notice rounding on the spectral bands so that the spectral range looks a bit bigger, all marketing). Can't seem to find the price of this sensor though. The resolution, grainy image and ghosting effect does seem the same as the example movies on the Indiegogo-site.And for this price I would expect nothing fancy. So, no calibration, lots of noise, ghosting in movies, slow response and software with almost no functions. But usefull enough for me to detect cold spots in my house or hot spots in my electronics.

content: Thanks for the insight Corporate666. I'll probably just keep an eye on the campaign and unless I see some rock solid evidence that he's actually managed to source enough parts to build it (and it's beyond the prototyping stage) then I'll probably leave it. Yeah, his claim that the LCD and processor are the most expensive parts give the impression he doesn't quite know what he's talking about.He reckons he'll be able to get the project done regardless of how much it costs to do it:QuoteNot that he necessarily will though of course. I was kind of under the impression that he probably is in some way legitimate , but then this update/comment showed up this morning. It was in reply to another person questioning the legitimacy of the project (the comment is now removed):QuoteIt probably would have been better for him to not post that comment; no evidence, just words. It only made me more doubtful about it. Now other commenters are questioning the existence of a prototype and even his four-person team. In fact, everything up on the Indigogo campaign site probably could have been made by someone in a single afternoon with a commercial thermal camera, an image-manipulation program, and a nice clean house.Anyway, there's still over two weeks left to go. I guess I'll just have to keep a close eye on it to see if any evidence actually shows up.~Josh

content: Well, the campaign is over (actually over 6 hours ago). I was waiting to the very last minute for some more evidence to appear but it never came. I also wasn't sure about how to pay for postage, so I didn't end up purchasing a perk.Actually they did post a video a while back interviewing some people behind the project but it didn't reveal much information at all.As mvdswaluw mentioned, it does appear as if it could be an april fools day joke. Not an unlikely scenario. There's hardly any comments been posted since it ended. I guess we'll have to wait until tomorrow to find out.~Josh

content: They ditched the optics?I thought the optics was the key to any decent thermal imaging camera?I have no idea how much the sensor costs, but it's possible they might be able to meet this price point without any optics and large volume. But how well will it performThere is no real prototype shown working.They mention they have to convince the major stores to carry the item, so that instantly raises the question if they are pricing the unit based on some huge volume theyhopeto achieve? i.e. they got a 10K piece sensor quote, or even higher pie-in-the-sky number.With only 1877 units pre-sold in the campaign, that's not a huger number by any stretch. I doubt they'll meet the price point with that volume.These aren't scams, but could be a classic case of not having any real experience with manufacturing costs. Time will tell.Delivery in May? - that's bullshit.

content: Wait, they say in the video they have dropped the expensive optics, but in the text say they have "some amazing optics." WTF?And the funds will be used for (among other things) "the hiring of a worldwide sales consultancy to sell Mµ Thermal Imager’s through to the hardware stores"I don't see how they can do this with the volume and the money they have raised.I'm getting the vibe that this one looks doomed to fail...

content: About the optics, the initial patents on molded chalcogenide glass optics have run out ... so those at least will probably be getting a lot cheaper over the coming years.I wonder though if for these low resolutions simple plastic fresnel lenses wouldn't suffice.

They've offloaded it to the Cell Phone.That's right folks, they claim to do IR optics will a Cell Phone camera.Maybe the CEO thinks they are up converting to optical frequency. But to do that you'd still need some kind of IR optics in front and mad science thermal IR:Visible magic physics package. But then how does it do the overlay?My bet: It's not exactly a scam but the CEO thinks his plan is a lot smarter than it actually is. The product might exist five+ years from now but will barely work under ideal controlled conditions.

content: Didn't they mention 1.5ft ~ infinity focus? Optics only necessary at distances less than 1.5ft. Which makes it harder to use for electronics, but still useful.

I'd be surprised if they have anything to show at all.

content: QuoteThis was the thing that made me more suspicious than anything else.Why would anyone making a product that hugely undercuts the competition want to slash their profitability by having to cover the large margin of a retailer?If the product is that revolutionary it will sell perfectly well online. Trying to push it to retail (at least initially) would be total insanity.Quote from: EEVblog on April 01, 2013, 09:47:39 amThey could very easily show something, based on conventional expensive parts. My guess is they will show _something_ to "certain selected clients".There is a company (linked above somewhere) claiming to have plastic fresnel optics that work at the resolutions claimed, and it's maybe plausible they could have a cheap detector - I don't know enough about the tech, however my understanding is the detector needs to be fairly big (in silicon terms) to get the sensitivity, which is never cheap, unless they are using something very novel like a plastic substrate.Every aspect of everything they have put out is so vague it just stinks of "nothing to see here" with no evidence whatsoever that they have anything real. The video makes me more, not less suspicious. If it is real they could EASILY show something believable. They haven't, so we can only draw one conclusion.

content: I agree, I think probability of success is extremely low on this one, but I would really like to have a thermal camera for personal use and IF the thing works, then I want to be able to seehowthey did it. At this price point, they must be using some novel kind of optics solution - the device package mock-up they have shown just can't fit that much hardware.I'm signed up for one, so I'm hoping they succeed. Once I get it (IF I get it), then I'll give it a good run-through and follow up here with pics / teardown / etc.

content: I'm guessing at least part of the cost saving must come from offloading the intensive DSP operations onto the phone/tablet/laptop etc CPU, so there only really needs to be a basic USB bridge inside the unit for interfacing with the camera.

content: They do mention on the original page that they can only ship to certain countries.ISTR reading somewhere that cameras below 9 FPS have less export control restrictions.However I think this is a minor issue compared to whether they have any chance of, or intention to deliver a real product.
