Funding for iFind Kickstarter Suspended 104

An anonymous reader writes As of approximately 9AM PDT, funding for the iFind project at Kickstarter, the one with the bluetooth tags that have no battery and that harvest energy from WiFi and other radio sources, has been suspended. No word yet on how this came about. Not an unexpected outcome since their claims of harvesting enough energy for a Bluetooth beacon from ambient wireless signals looked pretty far-fetched.

      It's not any one thing, it's the culimination of nonsense.

      They are going to market in 3 months, but there's not even a prototype to show, that's crazy if you've ever done hardware design work. They just need $500K, that's outrageously low for hardware, I know software startups which eat 10x that. Hardware eats a lot of money in test alone. Their claims are outside the range and specs for the technologies they work with. Not outrageously so, but ... enough that eyebrows have to be raised. Their "technical details" carefully avoid explaining why any of it is possible, and instead give intellectual symbolic links to why it might work and secret sauce.

      The things that are really dubious are the "shake to find" feature, which seems to be magical at best given how bluetooth works and what their claims are.

      Then people are background checking the CEO and while this may or may not be trustworthy, his alleged linked in pages does not give him the credentials he claims. He's allegedly got patents on cold fusion... Add it all up, and you have to lean on the side of scam. Maybe he's a misunderstood genius, but he's going to have to prove it.

      • Most of what you said makes sense but I disagree with the choosing side of things. You've seen software startups eat through $5m funding? I've seen them started in parents basements. I would say the opposite. $500k is way way way too high a price to pay for R&D of their proposed hardware. They should be able to pull it off for 1/100th that given the feature list.

        Or maybe they need the other $495k to change the laws of physics. That would make more sense.

          And getting a factory set up to run 100k units is itself an issue, you normally have to do a low volume run to shake out the problems, maybe 1k units (usually on prototypes). That takes money, lots of airline trips, and you pay a premium on comp

ASICs of the complexity that they need can be quite cheap, but you'd still be pushing it to get it done in $500K.

      For comparison, an RFID reader has the same FCC-imposed limits as WiFi, an EIRP of 4W (or put another way, a 1W transmitter with a typical 6dBi antenna).

      RFID readers are also generally bigger than a cell phone, utilize a protocol developed specifically for low power(Bluetooth is incredibly complex and high-powered in comparison, actually doing handshakes and stuff), don't do any more than transmit a number(essentially), and work at ranges a whole lot less than 200 meters.

      If we could build a wireless power receiver that doesn't need a specific power transmitter that can transmit powerfully enough to be heard at a couple hundred meters into something the size of a dime ALL small consumer devices would be looking to use it. Bye-bye chargers for the most part would only be the first step.

        To be fair Bluetooth Low Energy cuts out most of the protocol stuff. Obviously the range claims and power budget are still nonsense, but BTLE has gone a long way towards making low power sensor type applications possible.

      The problem is it's not RFID. They state it is bluetooth. Further more they claim functionality not even possible/correct with Rope etc. BTLE uses around 0.15 mW or 150 W according to a overview by DigiKey and according to Powercast and their P2110 Powerharvester you can get a few 10's of microwatts from a 3W transmitter at around 40 feet. This tells me it's not fesible.

      It's physically impossible because the power they need is a couple orders of magnitude larger than the power they're going to get. It's as simple as that. Passive RFID works because the power it needs is on par with available power. Again, it's just that simple.

      So, as you might imagine, the devil is in the details. What they have is not passive RFID.

      The difference is distance; RFID only works with the reader very close to the tag (or with a large, directional antenna). Remember that RF strength decreases by the square of the distance (inverse-square law) and even just a few cm away from the reader RFID tags stop working. These iFind tags would be receiving even less energy than that, and if you can't power an RFID tag with that you're not going to be able to power an active Bluetooth device either.

    The iFind project stunk of a pseudoscientific scam from the outset. Ignoring WeTag's laughable claims of the iFind being able to harvest any usable amount of energy from a device that small (RF harvesting circuits either need big antennas or to have RF energy beamed right at them), consider the biography of the so-called "Dr. Paul McArthur":

    Currently I am working out of Plano, TX. I have been involved in this industry since 1984. After I received my Bachelor of Science degree in Electronics and Microprocessor Design, I continued my education and obtained my two graduate degrees while I was also working full time as a senior RF design engineer in MRI, at the ripe old age of 28. My Ph.D. also included bipolar IC design at that point, but was more system level, concentrating on RF interactions with the body from consumer product sources. My other degree was medical.

    A bachelor of science degree in "Electronics and Microprocessor Design"? That's like earning a degree in "Computer Programming and Windows Apps". Pseudoscientists love to claim academic credentials, but always seem to screw up the details, because they want their credentials to sound as impressive as possible. And on the flip side, they'll never tell you where their degrees supposedly came from.

    Then there's the matter of the Ph.D. and the M.D. degrees, both earned by the age of 28 while he was working full-time as an RF design engineer. Really? So did he start when he was 12 years old? And I guess he never slept? And of course you could ask the obvious questions, such as:

    (1) "Dr. McArthur, what schools did you earn your graduate degrees at? And what years did you earn them?"
    (2) "Dr. McArthur, can you point us to the references for the journal articles that you published as part of your Ph.D. degree?"

    Not that you would ever get an answer, because "Dr. McArthur" is a fake. He was clever enough to pick a name that was less obvious than "John Smith", but still essentially impossible to track down using web searches.

    If you look into "free energy" scams, you'll find people like "Dr. McArthur" everywhere. Some of them buy fake degrees from diploma mills, and others just make up their educational credentials wholesale. If you ever find yourself dealing with someone who touts his credentials but won't give you a straight answer where and when he got them, then you can be certain you're dealing with a fraud or a pseudoscientist.

    • If you do some Googling for a Paul McArthur locator patent, you get two patents. That doesn't say he exist, but if he doesn't, somebody's gone to an awful lot of trouble to pretend he does, as one of these patents were filed 12 years ago (not Bluetooth at the time, obviously.)

    As far as I know, the device (if it actually could work) would be illegal in most of Europe. Charging a device with the EM waves sent by other devices is considered energy theft and thus forbidden. In the 1960ies, devices charged by radiowaves from a nearby radio tower were a constant theme in the electronic magazines, but later, this was forbidden, as it actually forces the radio tower to increase the emitted amount of energy to compensate for the loss due to the charging device.
    • If "stealing" 10 uW of power is theft we should at least compute the value of that theft. 10uW for one year is 0.09Wh and at 20 cents/kWh that is approximately 2 thousandths of a penny. That's theft about as much as me stealing an apple by sniffing a few molecules of it at the grocery store.
