*Updated 9/27/12
Quad Comparator
4 x Gates out
4 x Triggers out
Input 1 is buffered and normalled to Inputs 2 -> 4
So you can get 4 differently timed gates/triggers from the same signal.
euro rack friendly PCB

If you want a simple, CNC cut, tinned PCB with No silkscreen or soldermask
please PM me. The cost of the board is $15 ($12.50 a piece for multiples) + $5 postage(US) Shipping will be more for international. It ended up being about $10 to Germany.

Sure Very Happy
Glad you like.

it's simple too. If you just need 1 it'd be easy to knock together using a TL071 on pad-per-hole board.
Then again, my favorite part about the circuit is having the 1st input buffered and normalled to the other 3 inputs.

You can use it to get your clock from a spare, self oscillating filter or something, so you don't have to use up an oscillator or LFO (I have lots of filters Wink )

I'm teaching myself Eagle and I'm working on getting isolation PCB routing going on my new CNC machine, so I was looking for a small (but preferably useful) circuit to lay out, and this one will do quite nicely Smile

Thanks,
A.
