I want to make a magnetic switch where if a piece of iron is touching two magnetized surfaces, it completes the circuit, and a micro controller notices. I think I can make the surfaces from nail heads and magnets in a 3D printed housing. Is there a good way to attach hookup wire to a nail? Solder? Crimp? Other?
Found this new form factor of diffused LED string on AliExpress ( https://a.aliexpress.com/_mMg3nRi ) It looks like a rope, is 15mm in diameter, quite sturdy and moderately flexible. There is a silicone diffusion layer around the LED string surrounded by a woven rope-like sheath. I wanted to try to work it into a wearable, even though it's a bit thick for clothing, so I'm sewing a bag which uses this string as piping and a strap. I'll post an update once it's taken shape.
@geekmomprojects@MLE_online I have these little LED trees I found online. They use that white nylon mesh cable wrap stuff to diffuse the light. It works pretty well. I'll post another picture or two when I get home.
@geekmomprojects@MLE_online Yeah, the thick wire gives it the shape. The pixels are attached to that then the nylon sleeve is loosely slid over the assembly.
✨ It’s true. I’ve been working on this blog post for ten years.
You see, I’ve been slowly buying up nearly seventy super rare issues of a 80s/90s gadget catalog that meant the world to me growing up. And in the process, I’ve uncovered the secret history of this lost copywriting art.
PLUS, as a bonus, I’ve scanned every single issue — so you can read them all.
@cabel Don't forget that in the early 1980's you could get a free green JS&A TimeBall with your National car rental! I had at least a few of these growing up as a kid.
@blitzcitydiy Very nice! I have the 5" version. In keeping with the season, here's Madame Leota. I also display the Monterey Bay Aquarium's jellyfish cam on it in which case it looks like a port hole on a sub.
I submitted a pull request to the maintainers of the #WLED project on github today. My pull request adds support for the @olimex ESP32-GATEWAY board in addition to the existing support for the ESP32-POE board. https://github.com/Aircoookie/WLED/pull/3421
this is an aircraft avionics mystery! it's made by Bendix, but i have no part number because the cover is missing (bought it this way from our local electronics flea market). as this video shows, i got it to work, and this thread explains how...
@tubetime there's a parallel digital altitude format used by aircraft avionics. Is it possible this box converts a coarse + fine synchro formatted altitude input into it's digital representation? I'm not at home or I'd look up the name of the digital altitude format.
@ve7fim@todbot M5Stack has some sort of round LCD knob encoder thing in the works. Maybe calling it M5Ring. They've been teasing the mechanics and packaging for quite some time now. Maybe soon.
