The cost of posts and knobs can often be worth that much alone, but if you find some cheap pots and skip the knobs then you might be able to put something together in that price range.
Have a look in the Lunetta thread for some ideas. You should be able to do a baby 4 with a simple filter and 7555 EG for that much. _________________ JacobWatters.com |

I would have to breadboard it and test it out, and I don't have time for that right now.

Learning this stuff is half the fun. Then next time you can figure it out on your own, and pretty soon be giving schematics to other noobs here in the forums. _________________ JacobWatters.com |

I know the feeling. I've had alarm bells ringing here for 4 years and I still haven't finished the synth I want/need!
I'm not sure what you define as a 'synth'. There are plenty of little noise makers out there you could make. The budget is the problem. You aren't going to get much in terms of a full synth with that. I'd be looking at an Atari Punk Console or a square wave drone machine. The expensive part is hardware. Potentiometers, switches, sockets etc. You say you want to plug it into an amplifier, so there goes 1 socket. You need a battery clip. That would be around a tenth of your budget gone already. Potentiometers cost money. You can't really have more than say four or five with your budget. Then there's some kind of board to build it on. IC's, resistors, capacitors etc. And an enclosure of some sort.
I'd be looking in the Lunetta forum. You could probably make some simple noise maker out of a couple of IC's and some passives. have a look around there.
Perhaps there is a magic chip somewhere to give you a fully fledged synth. I haven't found it yet! |

Closest I've seen are the CEM chips, and they'll blow the hell out of that budget by themselves, well before you get to all the physical stuff you were pointing out. |

Hallo,
try WP-20 synth. Not very popular, a little outdated, but really fun to tweak. I build it much below 20$ (using chinese pots, but still below 20$). You can find some demo on youtube.

The WP-20 looks pretty interesting; that's basically an even more simplified version of the same idea as the Soundlab, which I've been building lately. |

I can spot a couple of omissions in that schematic.
First: VR2 appears to be a normal fixed resistor, it should probably be wired like VR1.
Second: no mentioning what IC's were used, which makes it impossible to build. |

My guess for the chips is a standard op amp (TL07X) and a hex inverter, probably one of the schmitt trigger ones, so a CD40106. |

Also:
(1) You should connect unused inverter pins to 0V (5 and 9 in this case).
(2) The op-amp pins suggest that a dual op-amp has been used (e.g. a TL072). If you use this, I would connect the spare op-amp up with the inverting input connected to the output (pins 6 and 7) and the non-inverting input to the junction on R13, R14 and C12 (pin 5 - this is at half the supply voltage). Alternatively, If you don't want a wasted op-amp, you could use a single op-amp (e,g, TL071) - pins 2, 3 and 4 as per diagram, pin 7 to positive (not pin 8 ) and pin 6 as the output (not pin 1).

Looking at this again that fixed resistor may be deliberate as well, since that's the control voltage side. Not clear whether the mistake is omitting the rheostat bits of a pot or naming the resistor incorrectly. I haven't build this circuit so I can't say for sure.... |

CV In controls the frequency of both oscillators thru "starvation." A "master pitch", if you will. VR1 makes the second oscillator variable for harmony, beating and general weirdness. _________________ Revenge is a dish best served with a fork... to the eye |

Sounds perfectly logical (Spock) to me. I must admit, I hadn't noticed the starvation CV control until you pointed it out I must pay more attention in future...
