  • That does help! Thanks for pointing it out, I didn’t think to check.

  • While it’s impressive in what it’s attempting, I can’t justify the cost. I even have a scanse sweep, already, and I just can’t. This seems absurdly overpriced particularly given that it’s likely to require some TLC to get working. Hacking something together with a stepper, a small 3d printed adapter which isn’t as pretty and a pi or arduino is probably what I’ll do instead. Or just never do it and use it as a single plane sensor.

  • I got one of these in the crowdfunding campaign, but didn’t use it for a long time, mostly due to not doing much electronic stuff lately, but last week I used it to do some power monitoring of a goto telescope for battery sizing, and it really kicks butt. The app works well, (get a 32GB microSD for the logging, they’re cheap now, so why not max out) and it impressed me at every turn that it worked well. Dual channel measurement and remote monitoring is surprisingly useful.

    Robotics folks, seriously, no brainer.

  • I used concrete countertop style concrete for a bathroom floor due to mechanical constraints. It had a ton of additives including chopped fiberglass fibers. I would use fiberglass over sisal, less affected by humidity and won’t rot out on you someday. (Of course this is probably a total nitpick, the electronics will probably die first, years down the road).

    There are some great colorants available via the concrete countertop industry, most notably Cheng and Fishstone.

    Other things to note is that Aluminum and concrete don’t get along (electrolytic corrosion I think), but 304 Stainless is ok. So I’d definitely seal the electronics before encasing them.

  • I’ve always found them good, but then I am using them for hobby stuff. Is there something specific about them that’s considered sketchy engineering-wise? I’m just wondering what the qualitative difference is, reliability or clean output etc.

  • Edit: description says black, everything else says clear. Assuming copy/paste typo.

  • I need something like this that then automatically rotates through around 8 single cells. Round-robining a top off/state check on each battery. ideally a channel expansion board, maybe 4 each, so you could just add as many ports as you needed. I2C controlled or such.

  • Whoo-hoo!

  • Hookup guide is 404.

  • Hmm, any relation to Conner Kuhns?

    That aside, look forward to seeing the build progress!
