  • ArduMower  Do It Yourself Robotic Mower!

    Sorry, can't be 'nice' here as they have not been so to me. DON'T make it. I spent a boatload of retirement money to buy the thing, and got large amount of parts in exchange. Those parts were not complete, and multiple sets of incomplete and out-of-date instructions, badly translated from German by non-German speakers, did not help. No real international support, but have to admit that maybe if you speak German you could make sense of the original instructions. The parts came incomplete, and for multiple versions of the same model. I had to buy considerable amounts of my own parts at my own expense to soldier on trying to build it. Finally gave up, and asked for a refund. They said no problem, ship it back to us, we'll deduct any parts used, and send you a check. So I did ship it all back…

And now it sits in German customs because they won't answer the phone regarding it. All it is is a bunch of laser-cut plastic boards and a handful of electronics off the shelf. If you think you can build it then be my guest, but why pay the premium when simple instructions are lacking.

  • Homemade/DIY Telescoping Pole From EMT (Electrical) Conduit

    They would also be MUCH cheaper ordering directly from Testrite: https://www.testriteoem.com/shop/catalog/shop-standard-telescopic-tubing/shop-standard-telescopic-tubing/block1375-1500-1-1-2-to-1-3-8/ I gather than the stated dimensions are for both the inner and the outer tubing, but those are for the OD of the tubing. So a little experimentation may be needed to get a proper fit for a larger trip of tubing, like 1-1/4"/1"/3/4". Thanks again for the Instructable, I'd never seen this sort of connector before. Oh, BTW, Testrite has a whole raft of different types of connectors: https://www.testriteoem.com/products/round-telescoping-aluminum-tubing-locks/ but the split collar ones you used make the strongest connection.

  • Homemade/DIY Telescoping Pole From EMT (Electrical) Conduit

    Aren't those split collar locks rather than cinch locks? They seem to be made only by Testrite, and that what they call them: https://www.testriteoem.com/shop/catalog/shop-standard-telescopic-tubing/shop-standard-telescopic-tubing/tbryb-s/ Cinch locks are a different type. These are stronger though. One other question, Testrite says the connectors have a 14-20 thread connector for the tubing? Did you need to thread the EMT? Thanks.

  • American Kestrel Nest Box

    A couple of things. One, the birds seem to like a 3" x 4" oval entrance hole more than a 3" circle. Find such an oval on the Internet(or use the one uploaded, it was 4"x3" before uploading), download it, cut it out, trace around it, and cut it out with a jigsaw. Better for the chicks I guess. Second, make the roof larger to overlap the front and sides, then cut a shallow gap at the top of the side for ventilation. Holes don't seem to be enough. The larger roof keeps weather out of all openings. I'd also like to see more on mounting boxes. Thank you.

  • Easy Battery Hack Using a DC Power Supply

    How did you determine the current drawn by the toy? I expect 1.5A is enough but it might need more if it uses motors. Shouldn't that have been factored in?

  • Keep the water temp below 180° or so if you have PVC or other plastic plumbing in the house. PVC softens at that temp and too long an exposure and your plumbing could disconnect itself. Bad news! No boiling water!
