Didn't think it was possible to make a CMOS linear, may just have to try this, but I think I'll stick with the basics since I haven't dabbled with lunettas much.

On the guidelines, I think that maybe more than 2 months would be better, as I'm a pretty busy person, maybe starting June to the end of August?
I agree with what Draal was saying (no op-amps or transistors only passives), but I think we should just limit it to what is in the assortment (no outside chips, gotta make due with what you got).

@tjookum, what's the source of the book you've posted?

linear operation is certainly possible. i've made analog vca's, vcf's, vco's etc with just cmos chips.

yes, no outside chips from the assortment and no transistors. thats THE CHALLENGE of it. if we could pick whatever it wouldnt be much of a challenge.

the source book was originally from, i think, Dr. Offset. I think it was just a CMOS book that had only those 2 pages on linear cmos.

I'm thinking that op amps shouldn't be ruled out. some people might like to perhaps use something like a LM386 to amplify the output so they can run a small speaker. I cant see why this would be an issue. It's essentially the same as running through a guitar amplifier or what have you. It shouldn't be a problem as it's no difference in just building the amp and plugging into it with a lead anyway. It would be nice to see some self contained units.

Personally I'll be using minimal components. Apart from the 25 IC's I don't think I'll be using any other 'traditional' electronic store components... such as resistors, capacitors, wire etc. I'm even thinking of eliminating obvious power sources.

I do like the range of ideas people are putting forward already. I'm toying with ideas which might involve a bunch of rotary switches to route and patch stuff.
I'm really looking forward to seeing what minus comes up with without "resistors, capacitors, wire etc" not using wire is impressively hardcore Smile

As for the discussions about linear operations - I'm going to have to go and do a lot of reading before I even understand what you guys are talking about. This whole thing is certainly a challenge!

Just itching to get my hands on a kit of parts!

Ian

Ian, I started a thread in this forum about Linear CMOS. It's title is simply "Linear CMOS" (IIRC). Perhaps you can report some of what you learn from study in that thread?

My parts arrived today. I asked wmonk in chat to flip a coin to select which bag i would use and I got heads, so this is the kit:

3 x CD4001 Quad 2-Input NOR Gate
1 x CD4011 Quad 2-Input NAND Gate
3 x CD4019 Quad And/Or Select Gate
3 x CD4020 14 Stage Ripple-Carry Binary Counter/Divider
4 x CD4022 Divide by 4 Counter with 8 Decoded Outputs
1 x CD4023 Triple Three Input NAND Gate
2 x MC14040 12-Stage Ripple-Carry Binary Counter/Divider
3 x CD4052 Quad 4-Channel Analog Multiplexer/Demultiplexer
4 x HEF4512 8-Channel Data Selector

I'm totally psyched about it. The discrete logic content is perfect for what I want to do, the counters are perfect for Boolean Sequencers, those 4022's can make 8 step sequencers I believe, and the 4512 and 4052 selectors / muses can select various data patterns. Overall it's exactly what I would hope for, a mix of the old and the new (with plenty of new) to challenge me yet also allow me to make use a bit of prior skills.

Oh, and the solar cells are cool and the speaker is nice too. I'm going to need to use an LM386 for the speaker driver, sorry if anyone balks at that but i am making a stand-alone waterproof sound generator with no i/o switches or anything at all, fully sealed and solar powered, so I need that speaker to work.

OK, I'm all set and ready to go, let's get this thing rolling!

Les

Excellent! Agreed, I see no reason why we can't use the 386 for our amp purposes. The circuit is very easy and necessary if ya want to hear the darn thing Laughing ! Your idea sounds pretty cool too.

Augh!

I'm sorry, I know it may not be fair but I simply cannot resist working on this project. I have to strike while the iron is hot, because I know I will eventually move on to other ideas and lose interest in this one (the iron will cool). Also I have given some thought to creating Lunetta art sculptures for sale as a product and that will require a lot of extra time. Designing a thing for production takes me more time than creating unique items.

So I will begin now and I'm going to try to chronicle my design in a text file and publish it later. That way I won't be cluttering up this thread with all my comments as I tend to do otherwise. I hope nobody minds that I begin now, for I must.

Les

Les, yeah why not!
after all it's a challenge between us and the unpowered chips rather between each of us, no?
and speaking for me, you're already miles ahead, anyways Smile

Hmmm. How long should we wait for more people? Those that are interested should strike while the iron is hot/or free time permits. Whether there are 5 of us up for the challenge or 25, I think it will be very fun what we come up with.

I think the main goal of this thread is to get some more excitement into lunetta building. Those that have chips, get rolling as time permits. For those yet to order, let's hear from ya. If it takes a few weeks or a couple of months, progress in this thread should offer inspiration to others.

I am still short on supplies such as hookup wire, perf and solder, so I can't start until I order. And THAT happens when I'm not zonked out from raising my 10 month old and 6 year old Laughing .

Yeah guys, don't hold back. I don't know when those of us out of the US will be able to get random packs, and it's all for fun anyway right?

Enthusiasm is a precious resource - get in and get at it whilst the iron's hot!
It would be lovely to be able to all start at once and work together but we're all in different circumstances so we're all going to have different start dates and different amounts of time and energy.

What's bugging me is that some people are blatantly cheating by knowing what they're talking about before they start - that's a dreadfully unfair advantage Wink

I may resort to putting bits of paper in a hat and pulling out 25 to get some random chips - or writing an excel spreadsheet to produce a list for me!

Now my Thomas Henry Quad Bass ++ is finished I can start concentrating on trying to understand CMOS and try to make a start on this.

Cheers

Ian

I'd like to comment on the subject of different skill levels, as it continually arises in friendly competitive events like this one. I tend to appreciate a build where you've put a lot of yourself into it. If that means you do an oscillator collectrion cause you're new and want to explore oscillators, then so be it. As some of us have mentioned I happen to be a heavy hitter in this one. Well, that just raises my bar all the more higher. I can't just slap together a Boolean Sequencer and use Linear CMOS to build a Karplus Strong (though that would be cool), because that wouldn't be all that much of a challenge.

What I will tell you is this: Last night i brainstormed an came up with something really really good. It is technologically interesting, thoughtful, reflective, and meaningful on a personal level. In fact, I had the notion that we could each have the option of either keeping our buld or how about this - send it to Stan. Wouldn't that be a nice gesture. So with that in mind I wanted to make something a bit touching, and this thing is. I want to tell what it is, but best to wait and see if it works well or not first!

Les

Haha, I mailed that thing to a friend who happens to be a knife collector. It took a while, but eventually it fully served it's purpose as a icon of abuse-fueled angry wrath. Now I have the song to remember it by, which is rather poetic if you think about it. When our time ends, if we're lucky and meet a good ending, the last thing to go is the hearing. Like the voice of a friend or lover long gone, the song reminds me of my seething desire for retribution against my perpetrators. I can laugh about it now. I did a remix of the song, My Secret Weapon, it's in the Mixes section of the forum recently posted.

Nice set of chips rosch! The 4554 and 4557 look very interesting and there's a couple there I can't even find info on...yet Smile .

rosch, could you post the description of those chips? I am not familiar wit those. An interesting part of this challenge has been taking a brief moment to study each person's chip assortment and imagineer what could be done with only those chips. Fun.
