SYNTHESIZER MAPLIN International eti4600 c1975

via this auction
"Designed in Australia by Barry Wilkinson & Trevor Marshall Aug.1975/6

Barry Wilkinson of ETI was responsible for the packaging and kitting coordination. It was adapted for Europe by Maplin Electronic Supplies of Rayleigh, Essex who produced full construction details, and were able to supply all the components for the project including PCBs, printed panels and case."

ARP SOLUS vintage analog mono synth

via this auction
"The Solus is one of the few mid-sized monosynths built into its own case! Feature-wise the Solus is like an Odyssey with fewer modulation capabilities. It still has two sync-able oscillators with cross-fading waveshapes, a ring modulator with an external input, and the characteristic Arp filter. This is the perfect synth for those who don't want to take their Odyssey on the road."

EDP Gnat vintage British mini analog synth half-Wasp

via this auction
"The smallest, full-featured analog synth ever? Most likely. The Gnat runs on six C batteries, has a two-octave membrane keyboard, a built-in speaker, and is made out of lightweight plastic. And yet, it has an oscillator with a wide range and three waveforms (plus white noise), a resonant low pass filter, an LFO with five waveforms and a rate which reaches into the audio range, and two simple envelope generators. It sounds cool through its little speaker, but plug it into an amp, and you have a synthesizer that sounds richer and more interesting than others three times its size!"

TOM WHITSHIRE VCLFO PCB

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.
