[sdiy] BTW, here's my project idea list for this year

[Paul Schreiber]

You can get rid of the FET/emitter follower buffer if you use a TL072 op amp. They are there for the large input bias current sucking of the Harris part. In fact the 3080/TL072 'loop' is classic Electronotes EN-72.

In case anyone is interested in taking a peak:

If someone has another cool idea I should throw into the mix, let me know... notice the projects at first glance may not look very original ambitious. Experience has taught me that getting a circuit like one of these working, debugging and tweaking it, and then building it and debugging it again "in solder" is plenty challenging in the time we have left.

My students are choosing their project this week. 

So far, the Korg MS-20 style VCO, Jupiter 6 VCF, Tau 1005 Utility VCO have been taken; one student wants to make a voltage-controllable wah-pedal type filter (this sort of thing has historically been popular; I think I've had at least one person wanting to do this every time I've done the class), another is looking at adding some additional voltage control to one of Juergen Haible's diode/resistor wavefolders, and another is looking to add some additional voltage control to the TB-808 bass drum circuit.

About 7 more people have yet to pick a project.

I listed the Rhodes Chroma VCO first since I would really love for someone would try it; I've listed it (I think) every year but no one has been brave* enough to bite...

(And yeah, I still need to get around to posting the project reports from last year's class!)
