  • Low Tech Greenhouse Automation : Cooling, Warming, Watering

    For context how cold does it get where you are at? How long did your calcium chloride warmers work for? (one night? Multiple nights?) Are you growing things during the winter?

    Polargraph Drawing Machine

    Thanks for the quick reply. I was working today on setting it up so that a raspberry pi zero can send the commands rather than have a computer setup all night. As I was working on this I noticed I kept getting weird behavior on the first few commands. To verify I hooked up polargraph directly and got the same strange behavior. Then I read your reply and it made me wonder if perhaps I was running an old version of the controller. As I said before I was trying all sorts of different tutorials on getting this up and running and fighting polargraph java code at the same time. So I went and found the latest source mentioned in this instructable and loaded that. The weird behavior I was seeing went away. So I am going to try writing a valentines note to my wife tonight and see how it goes.Than…

I really appreciate the help.(Now if I could figure out how to prevent chalk pens from drying out while drawing. I would like to draw more than just an SVG lines but I don't think my pen would last long enough for the other type of drawing).

    Thank you for the writeup. Between you and others I finally got my plotter working. Getting the software running was fairly difficult (Its possible that I got the software running earlier and thought something was messed up so I kept searching.)https://www.youtube.com/watch?v=4L0eSA47QocNow that it is running and drawing things I am running into an issue. After drawing for a period of time correctly it will then drive way too far in the wrong direction and then every command after that will get the error "incoming: MSG,E,Line is not on the page. Skipping it.".Finding the exact set of lines in the logs Dispatching command: C17,161323,96164,2,ENDLast command:C17,161323,96164,2,ENDregenerating preview queue.incoming: SYNC,161322,96164,ENDincoming: READYDispatching command: C17,1610…

  • Sodium Acetate BODY Warmer

    If it doesn't crystalize when putting sodium acetate crystals into your solution that either means the solution is too hot, or the solution isn't concentrated enough. The first can be corrected by letting it cool, the second you have to boil water out until it forms a thin layer of crystals on the surface.

  • CNC Pink Foam Surfboard

    I would love to see pictures of the build process and final product.

  • If you end up trying it I would love to hear the results.

  • Following this instructable isn't even possible anymore. The first product - Autodesk Remake - isn't available. I tried to use the latest software - Autodesk ReCap Pro - but their free trial software doesn't work, you have to pay to try it.

  • I don't think there are seed crystals stuck in the disc, instead flexing the disc somehow creates sites for seed crystals to form. When I have a stubborn disc I flex and twist the disc rather than clicking it and that usually works. I try and not deform the disc but I do flex/twist it up to the point of deforming it.

  • One other possibility is I think I used ziplock freezer bags. Maybe the thicker bag left enough opening around the stem for them to get through?

    I had read an article where they used paper bags stapled around the stems, so I figured I would try plastic bags (spraying was a pain and I had a bee-hive right next to it that I didn't want to affect). I thought I put them on early enough, but by the end of season most apples had a worm exit hole that went straight through the bag. Had I seen only 20% of the apples having issues I would have done it again, but I saw near 80%+ apples having worm holes. It was was a giant pain to apply the bags, and to get that much damage I haven't tried it since. Maybe I should try again.

  • I have tried this before and it didn't work. It didn't prevent codling moth worms from getting into the apples.

  • A couple of questions. Does the inner conducting plate need to be a tube or can it be a rod? Does the diameter of tube matter? Could this be scaled down so it is significantly thinner/smaller?

  • Thanks for the suggestion on the steamer. I have a rice cooker I could try that with.For the padded bag I was using a mylar bag outer bag to reflect the heat back. The hole in the middle was to direct the heat toward my body. If I fully enclosed it then I didn't feel the heat at all.My biggest problem these days is the vinyl bag. Vinyl is cheap and available but their seams usually fail after a few months.
