Fantastic! Great sounds you’ve made there! Could you use a 3 way switch and add another waveform.

In my "40106 Making Waves" video I showed how to get square, triangle, saw, reverse saw, pulse and inverted pulse waves from this chip. If you can get your head around the wiring you could switch to any of these, in theory.

Hey Alan! Thank you for making such a neat little noise boxes to work on -- and posting the stripboard layout so my electronic-lego brain could do it HAAH! I'm slowly working through them and enjoying the learning process! (I make predominantly guitar pedals -- made and Atari punk console and a dub siren -- but I wanna learn more stuff too!) I'm having a little trouble and was wondering if you could offer some insight? I made the board -- wired up all the offboard wiring -- and it worked for about 20sec -- then the board started rapidly heating up to the point the ICs were too hot to touch and about to pop. I swapped out the ICs, changed the vactrol etc -- but it still heats up like crazy and no sound comes out -- just the "you didn't do something right" buzz-hum. Any idea why it would heat up so much? Any suggestions on where to start looking for a problem? (I'm using a 9v guitar pedal power supply instead of a 9v battery and have tried switching mA from 500mA and 100mA -- as well as changing the polarity -- just in case that was it. also using a pre-made vactrol instead of a homemade one -- not sure if that's the problem either.) Any help -- or even theoretical knowledge would be awesome --- and thank you again for the cool stuff to try!

@CuSiSound 27 күн бұрын

Good to hear you are having a go at building your own. Also, it's OK to make mistakes, that's where most of the learning comes from. For chips to heat up they are usually drawing more current than they should and/or sending it to the wrong place (pin). Common causes to look for include; track shorts either stray solder or not fully cut tracks, misplaced connections eg something connected to the wrong pin, wrong polarity of power supply (though you have checked that), chips in the wrong way round (yes it can be that simple!). I still encounter some of these problems, particularly the stray solder issue. I usually check the circuit board with a magnifying glass to pick up any issues. The power going into a vactrol is isolated from the circuit board (they are used specifically as optical isolaters in some applications) so that should not be part of your problem. One troubleshooting method I use is to trace the circuit diagram on the circuit board. I start at one pin of the ic and match the connections on the board to those on the circuit diagram. It's a good way of spotting missing or wrong connections. Hope this is helpful.

@forktrus 25 күн бұрын

@@CuSiSound Thank you! And thank you again for the encouragement! Sucking at something is the first step in getting awesome at something -- right? HAHA! I haven't had a chance to get back at the circuit yet -- but I had checked (and scored) a few sketchy solder points that looked like they might have gunk between them. Good to know the vactrol is isolated -- that leaves less to worry about. When I get back to it -- I'll check the jumpers and where the power is going in -- I bet I misaligned something in there somewhere. Thank you again for getting back to me and for sharing your knowledge! Much appreciated! Cheers!

Hello, greetings from Venezuela. I am a fan of your videos/projects. Thank you very much for this. I have a question: How do I add a CV to that oscillator? I understand a little the design of the oscillator, but I had understood that it operated with 12 v. Does your modification works quietly with 9v? Regards

@CuSiSound Ай бұрын

Thank you for your kind words. Different transistors will start to oscillate at different voltages, I used the SS9018 as it oscillates just below 9v. Other transistors will need a higher voltage. I used a vactrol across the potentiometer to provide CV control.

Would this work with an Sk-100?? I really want to do this mod.

@CuSiSound Ай бұрын

This works with the SK-1 because it has the one step play function. Looking at online manuals for the SK-100 it does not appear to have the one step play function so this mod can not be done on the SK-100. Sorry : (

Do you mean R5 (1k) on the LFO switch? If so, that would ensure the signal only goes in the right direction so it could work.

@@CuSiSound yes i noticed a design elsewhere that uses diodes on all of the inputs of a sequencer and another op amp osc that had them and im wondering if that is the reason. theres a way to run op amps without vactrols to get true 1v per octave but ive yet to test it out as im still deciding what chip to use. just finishing converting six of caspers LFOs to one board and vco is my next project

Can i use 2n3904 transistor equivalent instead 2n4401

@CuSiSound 2 ай бұрын

According to the original circuit description the transistor is there to convert the trigger input to an S-Trigger which means it triggers by grounding the input. With my limited knowledge of electronics I interpret this as the transistor acting as a switch, though I may be over simplifying here. The 2n4401 is described as a general purpose npn transistor and the 2n3904 is listed as an equivalent in the datasheet so I would expect it to perform the same function in this application but I have not tried it myself. Please be careful if you are going to use any diy circuit with commercial equipment.

You can build the sub-octave circuit (4040 chip) as stand alone and run it on a +12v single rail power supply. I also built a version where the octaves outputs go through switches so you can select which ones are in the mix.

You probably could use a single diode. Look up the circuit for the Q&D VCF. It will change the characteristics of the filter probably reducing the cut off frequency range and altering the CV response.

I'm sure I would have used some ambience/reverb effect on the mixer too. Hope this is helpful.
