My first lunetta(?), TTL + 555s

Hi! Long time lurker here. I finally got around to start building a lunetta, or something alike. I've been really inspired by a lot of stuff being posted here so I thought I would share my creation.

It's quite a simple circuit, (so far...) I had a bunch of old TTL chips around so i saw it as a challenge to see what i could come up with using those. Unfortunately i only had 2 74193:s (4-bit counter) and did the mistake of not making the parallel load pins patchable on both of them, realized too late that you can create awesome stuff with those.

Anyway, It's been great fun building and playing around with this, and i guess i need to make another circuit now! I think i will go CMOS for my next one though. And thanks for the inspiration, all!

First post here on electro, long time lurker.

I was interested in the patch cables that you use on this. I'm a beginner with all this, I have been looking around the net but cannot find them. Could you let me know what they are or where I could find them.

Cool lunetta Natano!

@dirtyworm, might be these jumper wires http://www.sparkfun.com/products/8430, or something similar. Just search for female female jumper wires.

Thanks!

Yes, that's the same ones i have, i bought them from here: http://www.electrokit.se/kablage-mat-o-test-labsladd-0-64mm-0-64mm-hona-hona-100mm-set-om-10st_41002891 (swedish store)

However, i'm not too fond of these, they seem to be a bit random quality (some make really loose contact) and it is a bit tricky to use them when you have too many pins in a row. Also feels like you put a bit too much stress on the solder joints when fiddling with the wires if they are too close to each other.

I think i rather go for male connector wires and female on the board if i make another one. Have a look at sndbytes awesome creation in this thread for exampe: http://electro-music.com/forum/topic-30479-300.html

Yes, i saw it on youtube before it was posted on the forum, cool! (Rigaudio liked your vid)

I like al the variation, i'm making a patchable Lunetta too, kinda the same design Smile
