New User, New Chips.

txreceivable

Hi Crew.

I'm new to this forum but i have read through all the advice to beginners docs and suggested forums. I've arrived here via a Nicholas Collins book and Beavis audio.

I am very familiar with the flagship chips and still exploring them.
IE: 40106, 4011, 4040, 4093, 4096, 4024, 4017

I wanted to ask the forum if there is anyone here with experience from the following CMOS chips. I found these on ebay quite cheap and am excited about experimenting with them.

I understand that some of them may be quite useless or very similar to the ones above, but if there any really obvious/interesting ones to play with first, or others to stay away from. it would be great to know.

Here they are. Suggestions appreciated.

4000 - Dual tri-Input NOR Gate and Inverter
4008 - 4 bit adder
40106 - Hex Inverting Schmitt-Trigger
4011 - Buffered Quad 2-Input NAND gate
4015 - Dual 4-stage shift register
4018 - Presettable divide-by-n counter
4021 - 8-bit static shift register
4022 - Divide-by-8 counter - 4-stage Johnson counter
4024 - 7-Stage Binary Ripple Counter
4025 - Triple tri-input NOR gate
4043 - Quad NOR RS latch
4044 - Quad NAND RS tristate outputs
4052 - Analogue multiplexer-demultiplexer Dual 1-of-4 switch
4053 - Analogue multiplexer-demultiplexer Triple 1-of-2 switch
4060 - 14-stage binary ripple counter and oscillator
4068 - 8-input NAND gate
4070 - Quad exclusive-OR
4072 - Dual 4-input OR gate
4073 - Triple tri-input AND gate
4075 - Triple tri-input OR gate
4076 - Quad D-type register with tristate outputs
4077 - Quad 2-input EXCLUSIVE-NOR gate
4078 - 8-input NOR gate
4081 - Quad 2-input AND gate
4082 - Dual 4-input AND gate
4099 - 8-bit addressable latch
4512 - 8-input multiplexer -data selector with tristate output

Regards,

Welcome TX(r)!
Wow - the uses of those chips could fill a sub-forum. Oh...it already did - and you are here...!

I don't have any specifics for you - but if you read around this forum for a bit to get the idea of what we're doing, and you'll see most of them could be used in the types of devices we're making. I'd say get yourself a breadboard and start playing. Laughing

If you have questions about a particular chip, ask away...

Nice to have you here!

WOW!!! Someone on this continent has a fine collection of IC's! I'm having trouble sourcing chips since Dick Smith sold out and became Disc Smith. I did manage to pick up some 4040's, 4051's, 4046's, and 4066's locally today though.

I have been learning almost entirely from this forum, and Deathlehem (which I highly recommend). There's a couple of useful links around too, but you may have already seen them:

http://www.doctronics.co.uk/beastie_zone.htm#CMOS

http://www.kpsec.freeuk.com/components/cmos.htm

http://milkcrate.com.au/_other/sea-moss/

I'm sure there's others though. Check out the Link-o-rama. Anyway, welcome to E-M and the Lunetta Army! Have fun with those chips!

Hi Tr(x)! welcome to the lunetta forum.

Good to see youre also getting into lunetta's they are great fun and it doesn't take long at all to put something together. It's a lot to ask to explain all the uses for all the cmos chips, although you've made a nice list of very useable ones. All cmos details can always be found in the datasheets and the pin-outs on:http://kingswood-consulting.co.uk/giicm/

Great set of chips! Try them all in lunetta use.

The 4025 3-input NOR is particularly good for 'mixing' oscillators. Due to the chip's internals and the math of OR/NOR, certain frequency combinations come out as rhythmic or staticky noise.

Any D-register can be treated like a one-bit sample-and-hold, clocked at a different frequency than the data fed in. Put it in a feedback loop with XORs and multiple oscillators.

Any shift register is a multi-step one-bit sample-and-hold. XOR feedback makes pitched noise (LFSR). At the right low frequency ratios you get rhythms and notes.

Thanks all.

I certainly have a few projects to tackle here. There is over 1000 of these chips that arrived today!

/Minus - I have seen all those links thus far except i the drtronics one. seems to review these chips but i'm not sure if he is referring to the synthy-awesomeness of them or just likes them for other reasons.

/ezekiel - will difinately tackle this 2025 on your recommendation. sounds like you have had some nice results from it.

I noticed the 4060 (14-stage binary ripple counter and oscillator) has a sexy name. Do you think this is likely to be of advantage to audio projects?

thanks again crew.

1000 CHIPS!!!!!!! THAT IS INSANITY!!!!! I can see why you are asking for advice! Laughing

I'm actually starting to pity Melbourne once you have all of them hooked up! Laughing

1000 CHIPS!!!! ...not sure what to say? That's a great stash you have there!

hi all,

here's a heads up on some cheap chips. From the same seller i got mine, i have enough here so i won't be bidding on this one (btw, i am in no way connected to this sale). my last order was quick delivery and the parts are well packaged.

http://cgi.ebay.com.au/LOGIC-CONT-ICS-1073-PARTS-MCI-SERIES-SN-SERIES-NEW-/170518619403

another tip, if you search ebay with this line, you'll sure to find some bargains.

thanks tx for sharing that,

Although I don't think it's a good idea to start with buying as many cmos as you can. In the end you will be cheaper off if you selectively buy them at 30-50c a piece. When starting with lunetta's I just bought 10 of each of the chips in the beginners document by droffset. way to much! Im stuck now with 10x 4024 while I really only needed 1 or 2. Better to go with variety then bulk.

hi tjookum

I agree with you on the point that is probably overkill here to by in this kind of bulk. Here in Australia, it is a little bit more expencive to get these chips. I'm sure -minus- knows what i'm talking about. The local electronics store sells them for 3bucks+ each. althought there is mail order too, i feel that when working creatively, its nice to have things on hand so that you can work all crafty like.
in saying that, I think that getting 10 of each is a better plan. This is what i did at first and worked though the basics. now i've got the means to churn out a bunch of disposable synths.

side note; does anyone have a simple explanation for the difference between HEF, MCI, HCF. is there any difference with synth making?

I do indeed know what you are talking about! $3 each is way too much! Although, I recently bought an entire Dick Smith out of all its components! Cost $350. I got a load of stuff! Breadboards, heaps of LED's, hundred pots or so, stripboard.... tons of stuff! BUT, a lot of crap I will never use! Like 9 illuminated car cigarette lighters, 200 or so RCA sockets, and stacks of fuses etc. It was still worth it though! I was sad about Dick Smith letting us down on the component side by getting out of real electronics and moving towards 'consumer' electronics. I used to like my daily walk to Dick's to spend my shrapnel! But now I just have to wake up and walk into my lounge room! Got shit everywhere!!! Laughing

I may have to grab one of those IC bargains! Need to check what the other IC's at the bottom of the list are...

Thanks for the link! Very Happy

I agree DGtom, there is no such thing as too much cmos for lunetta building.

You have just planted a little seed with the 4051 pushbutton control, that can come in very handy indeed! thanks.

What I meant too say with the comment was that for a absolute beginner it might be better to have more variety then bulk. Im still thinking about a minimal "parts to start with" list, maybe ill get to that someday...

Wow! That's some stash of chips Shocked

! I'd treat it as a mission; like searching for the Grail. A house, wall to wall, made of lunettas.

Sorry, I'm having a 'Blade Runner meets Brazil' moment....

I'm a total beginner when it comes to lunettas; there's stuff I still don't quite get so I'm taking baby steps. But that's part of the fun - exploring various paths to the desired goal.

And it's personal too; my machine will be different than RF's, Minus' and Tjookum's. No 2 creations are alike. So, a belated welcome from me and we are all looking forward to some building news from ya Very Happy

That's awesome, there's heaps of stuff you can do with that collection. Maybe plop two or three at a time on a breadboard, connect LEDS to their outputs, and just put random signals into the inputs to see what happens. Then listen to it through an amp. Smile

-minus-, IMHO you can't have too much CMOS. They are enormously versatile and have hundreds of uses. When you've used some of the more common ones for other things, you then turn to the Wonderful World of Lunettas to use up some of the others. I've been waiting for over a decade for 4000-series CMOS to hit the market at 'surplus' prices, and it's just starting to happen - and I've been collecting too. Oh, and there have been some cheap CMOS books floating around too - I've recently picked up Don Lancaster's cookbook and Ray Marston's excellent book each for under £1.

As to the rest of your treasure trove, what's the problem with RCA sockets? They're more versatile than 4mm sockets, more rugged than 3.5mm connectors, cheaper than 1/4" jacks and pretty reliable. Plus they're compatible with bare-wire-and-a-match plugs. Very Happy
