<p>I built one of those. They are quite fun. Be aware it only
works with analog scopes. You can probably patch one up on
your modular synth.<o:p></o:p></p>

<pre>I buit one some time ago and it's fascinating to play with. It would be an interesting gadget to have at a synth meet or a gig without requiring the use of any of your modules. I recreated the original magazine article and saved it as a pdf so all the info is there, including the PCB layout (single sided). <o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>It's a fairly simple circuit and would be inexpensive to build if you can make your own PCB. The only parts you may have finding are the 4136 and the FETs.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre><o:p> </o:p></pre>
<pre>BTW, I'm still not exactly how the phase shift works on OSC C. If anyone can explain it to me I'll update the blog post and the pdf.<o:p></o:p></pre>
