via haxster on this electro-music.com thread."I was recently granted permission to do a run of this wonderful Digital LFO. Here are the details about it.
The pcb has been designed and I am asking who would be interested in getting a PCB?
I am expecting about $25-30.00 US dollars in cost per PCB. If alot of people get in the cost will go down.
Be aware that you need a Pic Burner for this project. The pic is 16F684. The hex file and asm can be obtained at the website above.
The pcb contains this:
(1) DIGITAL PIC BASED LFO, with glide and 4 LFO outputs. It has CV input also.
(2) analog simple LFO's.
(1) internal powersupply (option, if you wanted to make an external unit)
It has MOTM power jack holes.
It can be self powered if you wanted to make an external box or simply were pushing your current powersupply too hard already. The amount of capacitors is exaggerated for the circuit alone. You add the pairs you need. You can add them all and you will just have a really clean line. I added all the capacitors to be able to power other circuit boards also.
So far I playing with panel layouts everything seems to be fitting a MOTM panel space.
A few built items will be sold over ebay also for people who can't build.
Check out the pictures. The panel layout is not to scale. Most pots should have 1" spacing from each other.
THE POTS USED ON THE ACTUAL PCB CAN BE OBTAINED AT FUTURELUC ELECTRONICS. THE HOLES CAN FIT A "DUAL" POT, BUT THE ACTUAL CIRCUIT IS ONLY USING A SINGLE POT.
NO SPECIAL IC'S HERE, TYPICAL TL07X IS FINE.
THE TRIMMERS ARE TO EXACTLY ADJUST HOW MUCH VOLTAGE YOU WANT OUT (I.E. 5-0-5), AND TO DETERMINE THE SPEED RANGE OF THE DIGITAL LFO FREQ.
The digital lfo freq range does not go sonic. The other Analog LFO's are audible and can go sonic.
Why do i have so many LFO's on one PCB?
One Analog LFO is to CV input the Digital VCLFO. IN S&H mode you can make crazy arcade 70's sounds. The other ANALOF LFO was just to take up space. I like to have a shit load of LFO's.
I will post audio demo's later." see the thread for more.
