    Boards got here early. Pretty ridiculous that I can order custom PCBs, with SMD assembly, on a Friday, and have them the next Friday from China.

    Big order from DigiKey arrived yesterday, and an order of Deutsch Connectors are out for delivery today. PCBs should be here Tuesday!

    Also, PCBs have finished production and awaiting DHL pickup. Need to place a DigiKey order tonight for various odds and ends, such as the Teensy boards, pin headers, etc.

    Thanks! Your project is looking pretty awesome too!
    Wasn't planning on conformal coating - mine is designed more as a development board, where the user can configure to their use case using jumper wires (or I can configure for them). It will be going in a sealed enclosure (sealed enclosure with a vent is another option), so water ingress should not be an issue.

    Order placed for 15 PCBs! Should have in 2 weeks (maybe sooner).

    Board revision finished, maybe. Need to go back and double-check some stuff, make sure I'm not forgetting anything. I think I may order 15 of these to start.
    I will have to order the VR sensor signal conditioner IC separately and solder by hand. Nothing spells fun like 0.5mm pitch surface-mount soldering!

    PCB design updates well underway. Kind of a lot to it, so far I have the schematic updated and I still need to redo the actual layout. But, I am having a design review today with the design firm that's helping with the PCBs I've done at work, so their recommendations will get rolled into this one.
    Oh, it's getting a 3-axis accelerometer, too (ADXL362, +/-8g max). No gyro/magnetometer on this one - I haven't found any with good analog signal processing before they digitize it. Gyro would really only be helpful if you really wanted to record yaw rate.
    This project has me hyped!

    Certainly looks like a quality enclosure and connector setup.

    In addition to those 15 bulkhead connectors, I ordered 3 full kits (enclosures, bulkhead connectors, harness-side connectors, pins, etc) from a different supplier. Two of the three kits are missing a major component, lol. Honestly looks like someone raided the kits to fill orders for individual parts.

    Bulkhead connectors arrived. They are keyed so you can't mix them up:
    Pretty fancy!

    Whoa cool! I think that should be doable in several different ways. Do you know how I can find more details on how to program the set points or installation instructions or something? That might help clue me in on how it works.
