Heartbeat Straight Jacket

June 4, 2009

An EL project that displays one person's heartbeat on another person's costume.
  • Hey Barry! We’re being intentionally coy :) If we described everything we’re doing, what would be the fun in that? The full write up will follow. Again, we’re confident but there’s always that worry if we’ve got the robot functioning correctly. Won’t know until we really let it rip.

  • Three blinks, pause, three blinks is the SD init error. Try formatting your SD card on a computer. It could be that one of the solder connections on the microSD socket is bad - this is really rare and I haven’t seen it in 6 years but it did happen once back when we were dialing in the reflow profile on the socket.

    It really should be plug and play. Sorry you’re having issues. Feel free to contact us if you continue to run into problems. We don’t want anyone to beat their head against a wall.

  • If you use a solar shield there’s enough scattering of light to detect sun up / sun down and rough overall light levels (clear vs. very overcast). This can be helpful if you’re calculating charging rates.

  • Essentially, yes, that’s all you need. Depending how you lay out your PCB you would will need to re-characterize your 50 Ohm micro strip to get the max power output from your PCB or u.FL antenna connection.

  • That’s a really tough question to answer as it depends on how you implement your specific system. If your system just looks for a given EPC, then I can create a tag with your same EPC and act like you. This is how I think I may have copied my ski pass.

    If your system looks for a given TID, then it’s more difficult (but not impossible) for me to create a tag with your TID.

    However, if you get more advanced, the Gen2 protocol has key authentication challenges meaning you can’t just duplicate a tag’s ID or EPC. For the vast majority of applications this is very secure. But as we’ve see with the recent SHA-1 hacks that took over 10 years, everything is vulnerable eventually.

  • An external antenna will be listed in a few weeks. We don’t have plans to sell a keyfob Gen2 tag.

  • If you’re using a male header to connect one board to another you can skip the mounting holes. The holes are there in case you use wires and need to hold the board in place, say, inside an enclosure a few inches away from your main board.

    With many of my projects I’ll use the 4-pin JST wire harnesses. The connector gets soldered to my main board and the wire get soldered into the appropriate pins on the peripheral.

  • There are many UHF high-gain directional antennas on the market. We’ve got a good low-cost antenna inbound as well. Should be posted in a week or two.

  • The board has adjustable power output from 0dBm to 27dBm, meaning that with the correct antenna you can read up to 16 feet (4.9m), or 1 to 2 feet with the onboard antenna.

  • Ugh - I hadn’t even thought about smaller component orientation and hand placement. Indeed, even with larger 0603 sized LED it can be a challenge that often involves soldering them down and reversing it when the proto doesn’t blink.
