I propose a challenge!

This is a great idea. I'll join the fun also.

I like the idea of not knowing what you will get in the assortment.

Kit ordered Very Happy

! Anxiously awaiting...

Ordered mine last night... along with a bunch of other totally random crap Smile

I'm still keen to do this (although it is going to be a steep learning curve). It will be good enforced learning though so just the kick up the backside that I need Smile

Are you still prepared to mail kits to "the rest of the world" Psyingo? If so how much are they likely to be (assuming you add on a little bit for handling and to make sure you don't end up out of pocket)?

If not I'd be very happy to work to a random kit list and get parts locally if someone's happy to create a list (or open a random bag and report its contents)

Cheers

Ian

Yup, I'm happy to either send someone money for a kit or work with the same list of any of the other participants when they get theirs, and I can source the parts out here.

I just ordered a kit today and am looking forward to seeing what everyone builds.

This looks like great fun - but I'll have to sit this one out. I'll be watching from the sidelines with interest.

i have some random sets of cmos chips here that i bought from a german surplus mailorder. it also contains chips i've never dreamt of Smile

or can i maybe still join your order, psyingo?
although i'd consider germany a us protectorate i'm not sure that makes them ship to me.

I am totally in favor of both the challenge and the award of merit. I won't be participating in this one myself due to other commitments, however I wish I could.

My Goldmine Electronics ics came today:

4001 (2) Quad 2 Input Nor Gate
4011 (1) Quad 2 Input Nand Gate
4019 (4) Quad And/Or Select Gate
4052 (5) 4 Channel Multiplexor
4015 (1) Shift Register
4512 (2) 8 Channel Data Selector
4040 (7) Ripple Counter
4020 (2) 14 Stage Ripple Binary Counter
4093 (1) Yay, my clock source!

There are at least 6 ics here I’ve never used and I’m looking forward to breadboarding some of the more mysterious ones. Just one 4093! At least I’ll get 4 oscillators out of that. I have 7 4040’s and 5 4052’s which can aid in some clocking variety though. The 4512 Data selector looks promising, with 3 control selects to decide which of the 8 data ins gets to the output.

Things we should discuss:
1. Start time/End time
2. Reiterate the general guidelines like: No op amps or transistors. A least 1 chip to provide clock source; if one is not in the kit, builder is to pick 1 from their own stash. No clock source, no lunetta. Of course resistors and caps are allowed.
3. Let’s make it a minimum of at least 4 ics. This will allow for many of us getting our feet wet in this process as well as those with limited time. If you want to use em all, knock yourself out!
4. Method of connectivity is entirely up to the builder: nanners, alligator clips and nuts and bolts...you decide!

Just my 2 cents. Any changes, additions are welcome.

Alright, dangit, I'm in! Some thoughts:

1. On another site (for chainmaille) the award of merit is a little icon that goes belwo the person's avatar. We could do that. The Lunetta award anyone? For meritorious use of CMOS in the production of music?

2. I ordered two kits because I wanted spares and didn't realize they were random assortments (should read better, not skim so much). I also ordered a 24 pack of skinny little solar cells and two cadmium sulfide cells plus an 8 ohm speaker. I want to make this be a solar powered tonal varying optical art structure - should be cool!

3. I am most decidedly not a Lunetta purist in the sense that I believe we should be following the spirit of Stan Lunetta's genius, not the letter of his creations. After all, if Stan were to begin again today he'd do it differently - and cheaply. He might even use software synths as mosc suggested in chat because they have zero incremental cost essentially (once you have a computer that is).

4. Food for thought, with Stan's use of copper in creating electronic Lunetta art like his masks and such, the notion came up in chat that he is one of the originators of the "Steam Punk" style of art. In fact, he was making Steam Punk before there was Steam Punk, you could say.

5. While my kit is shipping, I would like to do some ChucK prototyping of some noisemakers, just for fun. At least that's what I've decided to do tonight with my late night energy. I code in solitude and I enjoy it. This will be a little side-project of mine and I will try to post audio and code of the results.

6. As a Lunetta heretic (opposite of Lunetta purist), I will be doing something rather unusual here (or at least I have not seen it mentioned much if at all)... Linear CMOS! That's where you hook up resistors around gates and get them to work a little bit like opamps. Well, i'll try anyway. maybe I'll play with that tonight instead of the ChucK, maybe I'll do both.

OK, too much rambling - I blame the caffeine! On to the task at hand!

if people get kits, id like for them to hold off brain storming and planning until everyone gets theirs. that would make it the most fair i think. i havent given any thought to my chips; ive been waiting for enough people to get kits.

I will still ship to people in countries that elec-goldmine wont ship to.
if anyone wants to help me out, they are moer than welcome to take a few names and addresses and work all that out. but if not ill do it no problem.

for everyone in other countries which need to get stuff reshipped, send me your addresses in a pm and ill to start getting shipping quotes for you. i will only accept paypal for this when it comes to it. shipping from canada might not be the best price, canada post is pretty notoriously bad. ill get a few quotes from different companies though, ups, purolator.

so yeah... hold off on brainstorming on those chips until the start date!

Hey, my kit just came in today. Should I list what chips were included? Or would people prefer to keep it a secret until more people get there chips?

I did get a number of chips I've never had before so this looks like it will be a fun challenge.

Inventor · Posted: Thu May 19, 2011 11:42 pm Post subject:

Personal choice here, but i prefer no secrets. It's all about the fun of sharing our experiences together, so by all means list your kit! (IMHO)

Linear operation from CMOS, that is a great idea. A CMOS gate is really just a very high gain amplifier. It makes for a very shitty OP Amp, but there are lots of neat uses for that nevertheless.

Inventer, I think you would work out some ideas to get this concept started, and post in a new topic. If some want to use those ideas in the challenge, so be it, but using gates in the linear mode is a more general subject, IMHO.

great to see this is starting to take off. That is a great selection of IC's Draal, Im personally curious about the 4019 wich could be a great way of radically changing the entire patch/sound.

i think a random cmos kit is a random cmos kit, so i guess i'll order one from pollin. but honestly, for me it could be all regular types too, as i have close to no experience so far.
i'll put up a list as soon as i have them!
btw this will be even more random, as they use to carry a lot of old soviet parts, that require digging through google for datasheets...

edit: did i say datasheet? actually it's more digging for what their equivalent is
