content: Thispopped up on Hackaday Projects today. (Here's a lo-fi mirrorin case they take it down, but there's not much content anyway.) I've already commented there. I don't know why they thought that was a good platform to promote it on. It's about as bad as trying to promote it in this forum! It's a good way to make sure Hackaday (who will slam it if they cover it at all) knows about it, I guess.Anyway, they havean Indiegogo campaignanda website. It looks like another "attempt" at the same thingRitot"tried". The main difference is that Blamix also includes touch surfaces for input and a finger ring that is to function as a telephone speaker. Blamix also claims to project on the palm instead of on the back of the hand. They call it a phone but say it connects to your existing phone using Bluetooth. No details whatsoever on the other technology they plan to use, of course. Get a load of this (emphasis mine):Quote from: Indiegogo campaignyetQuote from: Indiegogo campaign and Blamix websiteandQuote from: Indiegogo campaignFurther, the Gallery page on the website says they're going to stuff a 1700 mAh battery in that narrow bracelet…The "streanch goals" include GPS (what for?) and "contributors choice" (no details on that—I hope they don't plan to just let backers ask for whatever feature they want!).Comparison with Ritot:RitotBlamixvery many photos of models wearing ityesyesunisex, ambidextrous, one-size-fits-allyesyes—with "air cushion" to make up the difference on small wristsdevice models "available"21"available" in multiple colors & materialsyesyesplanned battery capacity1500 mAh1700 mAhcomes with inductive chargeryesyeswater resistance (good for washing hands!)waterproofwater-resistantchangeable projection coloryes, 20 (choose using charger)yes (choose using charger)dark projection capability shown in photoyesyessafety"absolutely safe for your skin and health""No danger for your skin and health"materials"Due to high quality materials and technical components, Ritot has extended operation life."see second quote abovestretch goalsmore colors, fitness tracker, contributors  choicemore colors & materials, voice control, GPS, contributors  choiceelectronics made to fit using a shrink rayyesprobablyquantities "available"1, 2, 3, 5, 10, 20, 501, 2, 3, 5, 10, 20I'll let you be the judge of those similarities. And I did check—the creators are not the same people (or are using false identities). These people are apparently from Moscow; the Ritot people were from SF.Also, that's at least three impossible crowdfunded products recently with bizarre names—Ritot, Blamix, and Bleen. Seems like a trend.

content: That 'prototype' makes it clear that this is without a doubt a scam. Those are just random pieces of some consumer electronics scrap. You didn't even manage to make clean cuts of the PCB.

content: Quote from: Blamix on December 09, 2014, 07:00:40 amAssuming you are the real deal:- You only had some photoshopped pictures of the design- Your projector can project dark light somehow- The device battery capacity is unrealistic- Your budget is completely unrealistic.- Your prototype is another dev kit, you have not shown how you will fit optics and projector into small watch housing like you promised.- The project, like so many other hardware projects on Indiegogo, will simply never deliver, or will deliver a vastly inferior product to what was promised.

content: The projector is huge in comparison with that was shown on a photo only because owing to limitation of the budget, we can't buy the necessary components!Made from this that was near at hand!Well, I will post a photo in case of bright light!

content: Quote from: Blamix on December 09, 2014, 08:10:11 amOk, let's have a bit of common sense here.You want to project around a corner. The problem is, you have to correct the image because it will be distorted. There are two approaches to this problem:1) You can have a considerably increased projection resolution and perform the correction in software. You still have to project it around a corner but you can compensate for a lot of the expected distortion by remapping pixels.2) You can have a lens set up which corrects the image.The problem with doing (1) is it requires more processing power, and most small DLP chipsets aren't made in resolutions close to 1080p which would be needed to get an image about as sharp as you show in your photoshop "prototype". Also, the large DLP imager would make the bracelet much bigger, and you'd use more battery power.And the problem with doing (2) is that conventional optics can't achieve the short throw that you're aiming for, when going around a right angle. Let's be generous and say you can project about 10mm above the hand (0.4 in), then you want to project this image about 4 inches away. This is laughably impractical. Sony has a short-throw projector - the shortest in the industry, about 12 inches wide, and it produces an image about 100 inches across. (http://www.computerworld.com/article/2487480/personal-technology/sony-plans-4k-short-throw-laser-projector.html) How much does it cost? About $30,000. And look at the size of it! That's for a ratio of 8.5:1; you're going for ~10:1 in your tiny watch.In addition, the slightest "ridge" on your hand, will make the rest of the projection distorted or go missing altogether!

content: Quote from: Blamix on December 09, 2014, 08:10:11 amPlease post a photo of your prototype projector shining on the palm of a hand at a steep angle, like it's coming from your wrist. Not from above. Have it project some text.There is no way you can get a usable projected image with a projector on your wrist. Simply thinking about the geometry makes that clear. We know it, and you know it. It will be smudged because of the angle. "new technology" won't fix that basic physical and geometrical limitation.
