First of all thanks for all the replies!

that's what the 555 CV input is for.. FM

really? you can do FM? Didn't know that... I have a batch of 555 timers, I could try building something from scratch, do you know where I can find some info about this? Like schematics or somthing...

Anyway I think I'll try the vactrol trick. They use it in the Voice of Saturn, which is just a derivate from the Atari Punk Console! So it should work... I only have to find the right led-LDR combo... I just ordered some stuff... let's hope for the best.

I’m a complete electronics noob, but this whole Shruti-Shruthi business makes me want to learn a bit of it, so I’m tinkering with my atari punk console, to see if I can hack it somehow. Now, I have a Novation Bass Station which can output CV and Gate from Midi, I was trying to feed the CV into the APC, but it wouldn’t work… The APC uses a 5556 timer (which is two 555 timer ICs combined into one afaik) pin 3 can accept control voltages and there is a pot (500K) controlling the pitch. If I add the voltage of the CV to the voltage somewhere after the pot, I should be able to modify the pitch with the CV, shouldn’t I? Anyway, the result is that the voltage from the CV (roughly between 2,5 and 3,5V) replaces the voltage in the circuit, and does not add to it… and in fact, I don’t hear anything, since the APC runs on 9V and 3V is really to low for it to produce anything…
Now I have one solution that could work: feed the voltage into a led which drives a photoresistor, which replaces the pot… should work, but have to try it out. But still I want to know what I’m doing wrong! I know it’s probably something stupid… but as I said, I’m a noob… so please tell me where I’m being stupid! smile

back again on this subject. Since I was busy with other project I had left is aside for some time, but now I decided to see if I could find the problem with that C64C. I removed the SID, put it into the SammichSID and voilà! It works! Even better than the one I had installed (less noise). In fact, when the SID was still in the computer I had run a few tests with joysticks and pots to see if it was responding, and in fact it was...

So now my guess is that it's either some caps, os something else is broken. I could go on and change all the caps on the board, but I guess I'll just leave it at this, and sell it for some ridiculously low price... anybody interested? smile

Didn't know that that existed! THanks a lot man, I'll see if I can find some!

thinking about that, actually I'm thinking about adding heatsinks to all the ICs in the C64. The only problem I see is fixing them... somebody suggested Epoxy glue between the heatsink and the IC, has anybody tried that? I'm also considering to remove the silver shielding cardboard, since I read that it does not really work as it was intended to...

all right I did the switch! Was really easy, and everything works, so I know I didn't break anything. I kept the cardboard shield thing... since I couldn't find any information regarding it. Now I only have one last doubt. the breadbox case seems to have less venting holes than the never C64C case, you think this is a problem? The SID is known for producing quite some heat...

btw. this kind of silver coloured paperboard shield thing... what is it for exacly? Can I just discard it?

yeah, the only thing I risk is to break the mobo while doing this...
the case of the breabox C64 is heigher but shorter, I guess the mobo goes under the keyboard a bit, while in the c64c the mobo and the keyboard don't overlap

Hi! A friend gave me an old C64 breadbox model, which appears to be completely dead. So I was thinking about putting the mobo of my C64C (the grey, boring one) into the case of the old one. Anybody tried that? Should I try it, or will I risk breaking everything? The connectors seem to be the same, I didn't check the screws that fix the mobo to the case though...

What are the extra knobs and I guess sockets on the front?

no there are no sockets on the front, just two knobs that control the input and output levels.
thanks for the positive feedback! I'll be posting some new fotos soon! I've made some better ones with a good camera and macro optics

After 4 months of waiting, prototyping and making mistakes I finally have my Shruti-1 case finished!
you know... I feel pretty lucky to own it, it's the most amazing synth in my possession!
If you're interested here's the complete story:

and here's some pix:

Olivier from Mutable Instruments is about to release the successor of the Shruti-1, which he called Shruthi-1 (with an additional H just to prevent confusion smile ) and it sounds even better than the first one, besides coming in a practical sammich format...

Agree with the others, you should try Wordpress! Get yourself a domain, with hosting, and a template to start with (or learn how to create one from scratch). You can do a lot with wp... my portfolio (http://www.papernoise.net/) for instance was made using wp and a template I bough from the web.
