Series and Parallel Circuits

August 20, 2013

An introduction into series and parallel circuits.
  • It’s the XSR: https://www.readymaderc.com/store/index.php?main_page=product_info&cPath=344_346_354_356&products_id=5127

  • Code is posted!


  • 1) I think I’ll be posting the code today, and I’ll leave a comment with a link here in the comments when I do so.

    2) Thanks, but I didn’t have to level-shift the inverted signal. It was already 3.3V.

  • I don’t have a plan in that regard, but it occurs to me that you could already use any number of other RF systems (not necessarily RC) to achieve that framework. Xbee’s, for example. You’re not committed to to using the RC channels or the 2.4G protocols used. I still want the gimbals and switches offered by a standard RC controller, but I wanted more control over what I could do with them. For the system you’re suggesting, I would imagine that an RC controller box like mine would be superfluous, meaning that I don’t think I’d start with that. But you could certainly hack the switches in the box with a uC or SBC…

  • Yes. Yes, you do.

  • I dig it. There are a lot of possibilities that I can foresee. Maybe a newly defined challenge event every year. But the one I’m most jazzed about (and actively working on) is drone laser tag.

  • That’s what I thought. And it’s not like no one’s thought of this - there are plenty of what you might call “research platforms” in drone format that allow for programming esoteric functions, but they tend to be really expensive. This would enable anyone with a garden variety racing quad to do some creative stuff without mucking about in the FC firmware.

  • Well…

    “We’ll also be having an autonomous human rider class.”

    To be clear, the PRS guys can’t come this year due to a scheduling conflict. But we ARE having a piece of the competition as effectively A+PRS. I’ve been calling it “Autonomous Death Race 2017”, but we’ll see if somebody stomps on that name before the event. Reference for you youngsters = https://en.wikipedia.org/wiki/Death_Race_2000. All hail David Carradine!

  • It will be held at Maker Faire Denver.

  • Maybe a piecemeal 3d printed approach? Then JB Weld the pieces together… maybe that’s too janky. Or CNC some wood for a nice… um, woody sort of thing. In any case, nice work!
