White noise/relaxation machine with 37 contact points, 1 of which is a pitch bend (the brass fastener in the center) and 36 of which colectively double as a crude sort of patch bay. Effects range from voice changer-like sounds to glitchy digital delays to dirty distortion and then some (an LM386 is featured prominently in the circuit). Switched output, though I think what I need to do is either bridge the speaker & 1/4" output grounds and/or add a NC reset power button, because switching between the line out and built-in speaker is temperamental at best.

I don't think I'll be seeking out any more tiny household hardware screw eyes in the future, not for this kind of work. They're a bitch to deal with as they don't take to solder particularly well and they heat up real quick; some here are actually loose because they got so hot that they burned a hole larger than their initial, drilled pilot holes.

I used 100% recycled wires: good for my conscience, bad to work with. I need uniformly smaller, more flexible ones in at least 5+ different colors. The resulting wire bundles were stiff and quite unruly even after zip-tying them.

I wish I had a better photo; I took some videos of the finished product in action, but they went on a little too long and showed basically the same kind of thing the first two videos did, so I decided against uploading them. No gut shot, sorry, but I can provide a wiring diagram if there's interest. There was definitely more than 37 points that could have been made into patch points; I just chose the 'essential' ones, and after completing the project, thus far I'veo nly found about half of those 'essential' points to actually be interesting.

shit metal covered in shit chrome, sand or file for better results, best to avoid

lets see both, this project is more interesting than you think

If you buy machine thread you can simply crimp ring connectors and avoid soldering to plated alloy.

Looks good!

^Ring connectors are a good idea, will definitely have to get some more (believe it or not I don't have a stash of those, despite having a stash of pretty much everything else I could think of for bending/building).

What is machine thread? All I get through google is sewing-related.

Similarly, do you know where I can get matching nuts and bolts with super small diameters? Like screws used to hold cassette tapes together, only with longer shafts (giggle). I'll occasionally go to Ace if I don't feel like waiting for something I ordered online, but their sizes only go so small.

search for "threaded rod"...

https://www.amazon.com/Threaded-Rods-St ... e=16410711

comes in many finish types, avoid the fancy stuff that is coated with zinc and chrome, cold steel is the best for soldering

should be able to get it at ace, if they dont have it then ask, my local ace guys will get me whatever i want

if you order online remeber the lengths of rod will affect shipping, 72" rods will probably cost you plenty so get the shortest possible

Whoa, yeah, me too.

Simple answer is: machine thread will accept a nut, whereas threads designed to penetrate wood, sheetmetal or drywall are far less equipped to do so.

Regarding search terms, it becomes useful to know the name of thread types. M3, M4 are metric, 6-32 (etc) are SAE.

So, 6-32 eye bolt will return something close to what I'd mean, in a variety of shapes and sizes of course. You can size the thread UP on this by going 8-32, 10-32 (common in rack mount, along with 12-24 server tower stuff), or DOWN by reducing the first number (odd numbers are available below 6)

There's a tipping point between size and cost, where going smaller will increase your cost based on complexity/popularity and going up will increase it on materials/handling. Amazon owns Small Parts now, so you can lose yourself in that rabbit hole online (at the expense of ethics depending on how you judge yourself) if you want to see just how fucking small you can go.

You'll face added cost unless you buy in bulk from a wholesale or trade supplier, because more people want to just buy a threaded hook they can screw into their kid's woodshop class picture frame, and you've got to buy nuts...

For soldering, surface prep is key and most non-specific to soldering items are not conformal to the needs to soldering, so experimenting with abrasives or chemicals (like rosin) might benefit you, but it's so much easier to service down the road if you're just spinning off a nut.

I was going to have a cool electro-mechanical device purpose built for a fest that was slated to occur last weekend, but the venue fell through and the fest was cancelled so I didn't bother sifting through all of my shit to find that one specific motor I want to put it all together. Stay tuned, I guess...

I built this sliding shelf instead:

This bend didn't come to be as it was a frustrating clusterfuck, but I'm posting these here to give you guys an idea of my process when starting a bend, and just in case someone else finds this same toy:

For some reason, they felt the need to add some weight to this undeservingly complex jig for the speaker:

Yep. Weird, right?
The jig was set up in a way so that the speaker is held in place between the orange circle with the eight-pointed star pattern of holes (as can be seen from the outside, looking at the top of the flashlight) and that orange container with the three nubs in my hand, which is roughly the size of a plastic soda botle cap.
Strange thing is, the speaker doesn't fit into the container itself, as it's meant to be sealed by screws with the baggie of metal inside: without the baggie, it's empty.
It's not like the weight is really needed, either, as the speaker is held in place primarily by pressure from above, whereas the container is below the speaker.
Why they didn't simply glue the speaker in like the majority of all cheap toys is beyond me, let alone why this comparatively complex jig with a hidden container had to exist in the first place.

Maybe they hid drugs in it and I just got lucky (unlucky?) :mrgreen:
