so i have settled on the 'thing modulator' as my first project. easy enough, very small, but where the hell can you get an LMC567?!?! i cant find it, not at smallbear, radioshack, or mouser!

also:
digi-key,
cmos version,
# lmc567cn-nd @ $1.89
or non-cmos,
#lm567cn-nd @ .77
not sure how the non-cmos will work, if anyone knows?

please keep in mind that you can only use the LMC567 Chip for this circuit. i tried to the LM 567 for this and i found out that you have to mod the circuit to get it to work.
just thought i would save you some trouble. antonio.
Mouser's got em ---
513-NJM567M......31cents 8pin DIP in stock
not CMOS version, but don't think it matters
"thing modulator"(?)
same idea as Anderton's EPFM RingModulator?

antonio,
thanks for the info!
in what way did you need to alter the circuit?

'Tis true, you're not likely to find a LMC567 at the neighborhood parts shop. However, as pointed out, Digikey seems the easiest way to obtain one.
nah, did a little searching, and for what im using it for i wont need to use the LMC chip. the reason tim changed it is because of all the noise he was getting from it when it was off w/ the LM chip, so he added the cap and the resistor from the + into the LMC567. from what i read if i use the LM567 and take out that resistor and cap it wont matter, i'll just get fuzz. it doesnt matter to me thouhg, i have a breadboard.
Using the LM567 won't give you fuzz so much as a ring modulator-like effect with lots of constant oscillator feedthrough. Using the LMC567 and the RC network cuts back the oscillator feedthrough to a more reasonable level, giving a more usable ring modulator sound with a internal oscillator that quiets significantly when the input signal is low.
alright, thanks tim, would the one at mouser work?
