Once again, Richard Brewster has enhanced our lives with the use of simple comparator circuits. I'm glad I didn't get around to the front panel, because Richard's idea sounds like a winner. Simpler, more flexible, more modular! My front panel will have pots for Frequency, FM atte

Dave, Looks great, I'd order one. A couple of minor suggestions: --Swap FM and Sub (select switch) controls (so their proximity matches their related function, as w/ the coures/fine controls) --Likewise, swap the FM and Synch In inputs... Might this make it in time for the next r

The sub outputs are buffered +/- 5 volt levels from the counter that muxes the switched capacitors. They are the sub outputs of the internal VCO. The switch selects 1 of four outputs and and the sub in adjusts the level as the second input to the mixer. A normalized sub in jack w

Maybe it's just because I haven't had my tea yet this morning, but I'm confused as to why there is a SUB IN pot but no corresponding jack. When I saw the four-position switch markings I assumed you intended to run what Ken calls the IN 2 signal through the NC connection of a jack

To the current Bi-N-Tic experts, What is the 'minimum' complement necessary for implementing the 'filter' part (if I understand what the Bi-N-Tic is about)? I'm assuming that the FReq, Damping, Bandwidth controls, and IN, OUT are a minimum set (?). For example, is the Fine Tune n
2005-05-08 by djbrow54
I really liked Richard's design for the CGS Bi-N-Tic filter with the sub outputs. I also like all the tic marks and this makes for a fairly expensive panel. We've collaborated and come up with a common design that we will submit as a Stooge panel for Larry's next panel run. This

I think I preferred the LM358 for the Grinder, as recommended by Ken. Dang, it has been too long ago. Truth is that I assembled the board and ran it on my bench, but I still have to build it into its Stooge panel. I've had several months hiatus on module building due to moving to

2005-05-07 by Adam Schabtach
Thanks for the summary, Richard. I did find some of your postings in the archives. I think that you mentioned that you were going to try other ICs also. Did you ever do that experiment? Was there anything to be gained by changing op-amps? Thanks-- --Adam > -----Original Message--
2005-05-07 by Adam Schabtach
Two questions: 1) Does anyone have manufacturer model numbers for the trim pots for the Bi-N-Tic? I'm about to order parts, I want to make sure that I get something with the right form factor, and I don't have anything handy to compare. I'd be extra thankful if anyone can suggest

2005-05-07 by Richard Brewster
I made the following small mods to my Wave Multiplier: 1. Added a 100pf cap between pins 1 and 2 of IC1 (Grinder) to prevent parasitic oscillation. 2. Added a 1K resistor to ground at the Grinder output to cut the amplitude in half. It can swing to +/- 14.5V otherwise. This mod l
2005-05-07 by Adam Schabtach
Thanks for dropping by my website. Yes, the Digital Noise does get really crunchy at low frequencies--it's really fun, and adds a very different flavor to my system. The Wave Multiplier is in fact the next CGS module that I will build. I purchased the PCB at the same time that I

Checked out your build blog and loved the sound samples, the frequency sweep on the white noise is great, it gets really crunchy, now I have to build one too! :) As far as more CGS, you should build a Wave Multipliers, that's my favorite module so far from Ken. - Michael nil-x --

Okay, I uploaded a demo .wav file of the Bi-N-Tic Filter (in the sound files folder). I fed pink noise to the signal input, and just a teensy tiny bit of low random voltage to the linear FM input. No filter feedback to the input. Frequency control about mid range. Halfway through
2005-05-07 by Richard Brewster
I just uploaded another FPD panel design for the Bi-N-Tic. My idea is to use a CGS56 gate converter board to buffer the 4 counter outputs, which I call SUB1-4 on the panel. These are +/-5V outputs. Internally they go to the SUB IN selector switch, followed by the SUB LEVEL attenu

2005-05-06 by sasami@hotkey.net.au
The first thing you need to do is work out what voltages the AS and Curetronics supplies put out. If they are +/-15V, all you need is to wire up an adapter cable. If they are +/-12V, they should work, but the occasional module will need modification (VCO, Bintic). If they are not

The Precision Resistor people are great to work with. Any size order, above the minimum, is shipped fast. I bought enough resistors to cover the minimum, but now with the Bi-N-Tic filter added to my two VCO's, I wish I'd gotten more! After all, they do keep and I know I'll be bui
2005-04-26 by Adam Schabtach
