hi all,

I finished my new project and ts is basically a modified version of the 'heterodyne space explorer' by beavis audio, the only things i have changed are some potentiometers, I just left them completely out in the mixing section and I changed one of the pots by the oscillators with a switch.

I'm already happy with the sounds but not yet with the looks...
somebody has any sugestions on how to put it in a good looking box/enclousure?
(I will add some nice control knobs, I have already ordered them)

thanks garcho, these things all look great. I think it will be some kind of homemade enclousure in the cigar box style for me! Smile

Make sure your pots' and jacks' shafts are long enough to go through however thick the wood in your cigar box is, before you start drilling.

thanks for the tip, I was already looking for a cigar box, but I came out on a good looking empty wine crate, but now I see the wood is way too think for my pots, switches and jacks... So I will have to keep on searching...

If you're willing to spend a few extra dollars, you can order long shaft pots that will fit through many inches of anything. Same with jacks, but I haven't seen many switches with long shafts.
or
If you use a wide spade drill bit, say 1" or so, you can bore a 5/16" hole for your pots and have a 1" circle faux-routed about half way through (careful with that drill Eugene), which will be then thin enough for your pot's shaft to poke through enough to bolt it into place. As you can tell, my handyman vocab is lacking, so if this doesn't make any sense, I can post a picture of an example for you. The only issue is you will need more space between pots, to accommodate the 1" circle routing. Remember to do the faux-routing (won't be faux if you have a drill press) first, THEN the standard twist bit drilling. If you do it the other way around, the spade bit will flail all over and give you a rough, curvy triangle instead of a perty circle.
Wine boxes look really nice and are sturdy, so I suggest trying to make it work somehow if you can.

ok, I think I get what you are saying, just drill very large holes so the pots fit in them entirely and then a smaller hole in the middle of the big hole for the shaft, right?
It sounds great if I could do it like this. I will definetely try it if I find the right tools for it. And if I use the wine crate, i will still have some spare room to put in another project in the future so I think I will make it like this.

Thanks a lot for all this usefull info Very Happy

I guess those cinch connectors are for the power supply, nice.
but it does make me wonder why not use one connector for both + and - ?

Coulda woulda shoulda. haha

I started out my little electronics adventure as a circuit bender and i used the same RCA style connectors for patchbays all the time. I started connecting one wire to both terminals back then because i only needed one wire between points, i didn't have to totally plug it all the way in when searching for bends, and i had better connectivity that way... So I guess I did it like that just out of habit

Here's a short video of my machine . Outputs of a 4040 and 4094 are connected to the 4512 data inputs. The 4512's ABC controllers are 3 different oscillators but you can mix that up with any logic really. The output pin of the 4512 goes to my pitch tracker which creates some interesting sweeps.

@Minus - Yeah, I have been busy keeping up with my 2 sons, which is getting to be a challenge. But childhood only comes once, so I'm enjoying it. I purchased those cords from evil bay and I can't think of the seller offhand.

I'll see if I can find out who they were. I think I bought 10 for 20 dollars? They have a great rubbery feel and have put up with my abuse very well.

@Mikmo - He likes my mancave, which proves it's genetic Cool . Adam is going to be 2 years old in July. Which makes this hobby about as old for me.

Thanks for the link. Shipping is the killer though. $17.95 US to Australia. I may have to look elsewhere. Sad
