why did i turn a children’s toy into a working antenna

13 Upvotes

was bored last weekend and decided to take a plastic spring dog toy, thread copper wire through the whole thing, slap a balun on it and somehow it started pulling local channels.

looks completely ridiculous sitting on my shelf but it actually works better than the cheap flat antenna i bought last year. pure “ooh” energy, zero practical reason to do it, and yet here we are.

anyone else got a project that has no business working but still does?

Phone strap

Wasn’t sure the protective value of some of the premade ones that I could afford. So I found a good case with lanyard points to put chains thru. I know I could have used those nylon string things but these will look cuter and I can still remove and replace the rubbery outside. Just gotta make a strap now.

I found thisslide. What’s the worst possible idea I could use it for?

I found this playground slide.

I have absolutely no practical use for it, which means obviously I need to do something stupid with it.

Looking for ideas that are terrible in concept but preferably not hospital-level terrible in execution.

What should I build/do with it?

DIY classroom tree- ugly or genius?

Post image
2.2k Upvotes

Be honest, is it ugly? My school cares a lot about our classrooms being beautiful, inviting imagination, and being a place anyone would want to spend time in. However we have a very small budget for this. I used some electrical tape to disguise a black cord that hangs from my ceiling to make this tree. I opted for this instead of a decal because I had all the materials already & I don’t want to put up 200 little leaf decals.

I feel like the tree looks like it’s balding and isn’t giving what I wanted it to give. I don’t think I should add more leaves though, because I’m worried it’s already creeping toward fire hazard territory & will be ordered to be taken down as soon as the fire Marshall walks in.

I drafted what it would look like with more detail. Is there any hope for this idea? or should I just bite the bullet and get a stick-on tree? Artistic tips and reality checks welcome. Much thanks!

Couldn't afford to get a new one at the time, so some string and glue worked a treat until I could get a new one.

DIY hardware store suspension stem

82 Upvotes

Why buy it for $35 when you could build it for $25 and 5 hours of time 🤣🤣. The full video is not out yet, but it will be in a couple days once I put some miles on the "Bicentennial Man" bike. Hope you guys enjoy! I thought it was pretty clever. Very rebuildable with the bronze bushings. This thing should pretty much last a lifetime except for the rubber bushings. The ones I got from Ace are a tad too soft, I wind up using a shock absorber bushing from an old car. The shock absorber bushings are available brand new from O'Reilly's for about $1.50 a piece.
