New Effect: Vanishing Point...again

[The Tone God]

I just posted a new article/effect at the site. Its a new Vanishing Point. It has 10 stages, stage selector, manual reset, sequence and random modes, and uses only two logic ICs. There is a PCB and layout availible for it as well.

You can find it here:

Enjoy.

Your Tone God,

Andrew

Note: The first Vanishing Point has been renamed to "The Original Vanishing Point".

You've really done homework !!!
 Neat circuits Tone God !!!
 Great Essay !!!

[Marcos - Munky]

Let me say COOOOOOLLLLLL!!!!! :twisted:  :twisted:  :twisted:

[Peter Snowberg]

As usual, your engineering and description are absolutely top notch!

I love the article and the design!

[Phorhas]

Truley awsome... very interesting concept... these things shall be the first on my list anfter I'll get over my OD phase

[StephenGiles]

This looks very interesting indeed, much bedtime reading!

Shall I tell you what your next assignment is? Well, perhaps an active mic splitter, that is to say a means of producing 2 isolated balanced outputs from one balanced input so that, for instance, it is possible to drive 2 separate mixers from one balanced microphone. And the second part is a piezo pickup preamp (very high impedance input) with a dual balanced output. A tall order???

Wait, so what does this do exactly?

[Arno van der Heijden]

Very cool!!! Instant Ooh Wah :mrgreen:

Time to order some samples from TI....

BTW, can I use CD40106 hex Schmitt inverter gates for the oscillators?

[The Tone God]

Thanks to everyone for the words of encouragement and that is what they are to me. It makes me want to do more. I appreciate it.

...these things shall be the first on my list...

The Tone God demands build report when finished!!!

Shall I tell you what your next assignment is?

Mere mortals do not tell The Tone God what his/her/it's assignments are! Besides a have a list with a couple dozen items on its way. I want to get through the list then I may get in to that. Sorry.

BTW, can I use CD40106 hex Schmitt inverter gates for the oscillators?

Yes. In one of the earlier builds I used a CD40106. You might have to do alittle tuning mainly in the pulse detector but otherwise it should work as shown. I might even do a PCB layout for the 40106. The circuit is simple enough that it could be perf'd easily too. I ended up using the 4093 for the following reasons:

1. The 4093 seems to be the most common and easist to find schmitt triggered gate.

2. A NOR gate could be used in it's place without modification which gives more choices for parts.

3. I like to use up all the gates in a package. With an inverter I end up with two unused gates. Not a big deal though.

4. When I was playing around with the circuit earlier I tried gating the clocks. I decided the circuit shown gave the best results and I was too lazy to switch it back to the 40106.

5. I have a bunch of 4093s lying around from Wicked Switches. :oops:

Very cool!!! Instant Ooh Wah

I wouldn't call it instant. You still need the audio section, optocouplers, pots, etc. Its just the brains you still need the body. I suspect the Ooh Wah's logic provides a cleaner result. This has some "hackness" to it but it works and is good enough for DIYers I think.

Thanks again to everyone.

Andrew:

Nice work.  Once I finish the two projects currently on my bench, I think I will check this out.

Best regards

Nice work.  Once I finish the two projects currently on my bench, I think I will check this out.

Thanks. I would love to get some build reports to see if any tweaking is needed for the circuit.

Good luck and feel free to ask any questions.
