  • The title of this suggests it's a liquid level sensor but it really appears to be a flow sensor as per description and datasheet, yes?

  • SF, please include the typical ranges of the sensor as documented here: https://groupgets-files.s3.amazonaws.com/lepton/Lepton%20Engineering%20Datasheet%20-%20with%20Radiometry.pdf

    Intra-scene Range: High Gain Mode: -10°C to 140°C (typical) Low Gain Mode: -10°C to 450°C (typical)

  • how structurally sound is it such as mounting on a spinning platform for scanning of a room? aka 360 horizontal spin with 90deg vertical traversal?

    "how fast can i move it?"

  • +RobertC how about a preformed 2xN header strip that one side of the pins is bent 90° twice so that each side will plug neatly into the center of a breadboard?

  • does sparkfun have an IDC styled cable that can plug into the middle of a larger header, aka a 2x5 put in the middle of a raspberry pi's header? i know others make them with the crimped socket on one end and snap in socket on the other, but i like shopping at sparkfun.

  • any idea if and when you'll carry vertical JST sockets?

  • the input on these drives an IR LED on a photo triac, already optically isolated

  • hmm. the arms in the first photo appear to be out of position - "off by one"

  • good grief, what a bunch of rude jerks. especially the HORDES of new users. did any of you have to pay to participate in free day? no. so stop being asses if you didn't get all of a $100 allotment, or even anything at all.
    everybody knows from the start that it's going to be hellish to get a page to load during the entire event. if SF servers were capable of lightning fast responses for everyone, the entire event would be over in a few hundred milliseconds, and we'd still have an angry horde of jerks. $150,000 / $10 per question == 15000. with $100 per person, that's 1500 people at perfect answers.
    either it goes fast, or it goes slow. but do the math and stop whining. spreading $150K around will get thin quickly.
    appreciate SF for what they give back, and what they do for the community. it's a hell of a lot more than what -you- are doing.

  • hey HM,
    well i'm not familiar w/ the pic32 but my immediate reaction is to attach a serial to parallel chip in there if i already have this module in hand. i use 8bit data access on this module, 10 bits for address. so you'd want a total of 18 bits for those two busses, and you'll need four more pins to manage. if the wiz830mj is the only device on the bus, you can hardwire /CS to ground and rely on signalling with /RD and /WR. the last two pins you must use are /RESET and /LINK. /RESET is obvious, and /LINK indicator is important since you don't want to send packets when there's no network connectivity (it can hork up the w5300 on bootup).
    do you have SPI or i2c on the pic32? you can use the mcp23s17(spi) or mcp23o17(i2c) io expander. that'll give you 16 bits of bidirectional flow per chip. see the datasheet for info on that critter
    digikey has plenty of different i/o expanders to choose from.
    if you want native serial access, the wiz812 may suit you better. it comes with the w5100 chip rather than the w5300 chip, so it gives you four sockets rather than 8.
