  • This is the same sensor as in the Flir One, so IR resolution is the same. It’s possible it has different firmware, so may not support all the modes documented in the datasheet.

  • Although the Seek has higher pixel resolution, the noise is higher, and they peg the displayed temp range quite wide to hide the noise, making it less sensitive to small heat changes than the Lepton. Note how Seek don’t publish a spec for resolution. Lepton has a simple, documented interface, and all the processing is built in. They avoid the need for a shutter by clever processing based on the assumption that the scene is moving. You would need a shutter if the sensor is stationary, or you want to measure absolute temperature.

  • According to that PDF, the trademark expired in Dec 2013 - probably at least worth checking to see if it has been removed. Can the yellow holster be removed - could they just destroy those?

  • Should have used a gold finish for boards like this with bare contacts - silver tarnishes too easily.

  • Re. devboards, I think there is probably a good argument that they could be exempt as “A digital device used exclusively as industrial, commercial, or medical test equipment.”

  • A decoupling cap would have been nice…

  • I think the ‘minimium load’ spec in the datasheet means minimum resistance, which is slghtly confusing as it could be misinterpreted as the device requiring a load.
    If it meant minimum current load, they would also quote a maximum, which they don’t.

  • 1) Why not have a ‘surplus bulk parts’ section on the website?
    2) Ebay - plenty of people buying & selling bulk lots of components
    3) There are plenty of chip brokers, but chances are they all check ebay so option 2 with a sensible start price is probably at least as good an option.

  • Like Siftibles then…

  • Jassper -
    Wrong date code - my guess is the copier didn’t have a real 328 to copy but copied a 168 and changed the part no. without realising the datecode would give it away.
    Why use copper ? - it’s a standard IC package, so that’s how it comes before the chip gets put in there - too much effort to remanufacture in a cheaper metal. Also means the weight and magnetic properties are right. Although weight is minimal, the difference in weight for a reel would likely be noticeable.
    Why send anything at all & not just take the money and run ? It is entirely possible that the person SF bought these from did not know they were fake, and were themselves duped. It is also possoble that the seller assumed the chips would be sold on or held in stock for a while, so there may have been a chance to make more sales before they were found out.
    As regards payment method - Deals with China are almost always done by bank transfer or Western Union, which are non-reversable and the sender has no comeback. You can be sure the bad guys will have covered their tracks.
    Not buying from China is rarely an option these days.
    Any manufacturer who allows their leadtimes to get out of hand is at risk of this. I bet Microchip are getting more design-ins recently. All the technical advantages in the world are pointless if you can’t get the parts.

No public wish lists :(
