One post, One component - An experiment

[phector2004]

Here's a fun idea: an evolving circuit. I don't know how this'll turn out, but it's worth a shot

Basically, it's designed by the whole forum one piece at a time.

Rules:

1. You can only place, modify, or remove one component per page of this thread.
2. You have to modify the circuit based on the latest version. Even if it was posted 1 second before you 
3. You can't change something that was just added. You have to wait another turn before you can mess with it.
4. Someone has to build this at some point 

Hopefully there'll be more than just 4 components!

Here's my contribution:




P.S. Try and keep it small and legible. I'm using paint, saving as a monochrome BMP

Im actually unable to edit the pic but I'd choose the most common road and add a tranny in htere.. say... mmm 2n5088
could you add it please ??

Vendetta's contribution and my own:



SSRP time! (Or something else...)

[phector2004]

I like where this is going! 

[Ripdivot]

470K resistor to vref (bias) from the tranny base

[vendettav]

that's already some weird stuff, like the 2n5457 above the 2n5088 lol... could be used as a switch??? i have no clue where this will go 

[CynicalMan]

[deadastronaut]

cool idea.....

i'll have a 100k trim on the drain of the 2n5457...if someone could do that for me?..

edit: one per page!.....ok, i wont cheat!.

[Hides-His-Eyes]

5088 470R resistor from emitter to ground

[CynicalMan]

[deadastronaut]

nice one alex...

its going to be interesting to see how, and what this develops into...

[Jazznoise]

50 uF capacitor on junction between Source of FET and Collector of Tranny and goodness knows what else!

[frequencycentral]

Who's going to be first to say BSIAB?

[CynicalMan]

BSIAB!!!!!
Do I get a prize? 

[ayayay!]

470 mH inductor next in series. 

[phector2004]

Never saw that one coming!  

Oh and kudos to Alex for updating the schematic
I'll try and get the next one lol

How's this? Or did you mean in series with the trimpot?

[vendettav]

this thing so far goes really weird and cool at the same time!!

ahh hopefully i'll be able to breadboard one haha

From the 9V (where the trimer is) a cable to an IC (TL072) for a future LFO!!! 

[earthtonesaudio]

1N4147, anode to JFET gate.

From the 9V (where the trimer is) a cable to an IC (TL072) for a future LFO!!! 

please enter somewere on the schematic, on my behalf, one resistor 47k ( I like its colors  ) as a starting point of Vref, needed for the above)
