  • 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!

  • Pressurized propane doesn’t need a pump. A regulator might be good though…

  • Depending on the dimensions, some plaster of paris and a popsicle tray might make perfect sensorsicles. Not sure how much that helps with corrosion though.

  • Does anybody know if one can bodge this together with lcdproc without herculean effort? I expect to be using a usb/serial adapter, motherboards being sans serial these days.
