Lunetta Workshop Ideas |
|
|
Hi everyone, long-time lurker here. I started out building and bread-boarding lunetta circuits with this communities help maybe 6 or 7 years ago. I've built a ton of awesome lunetta synths thank to the wealth of information here (full set of Castle Rocktronics modules, logic noise etc.) and while I've mostly been focused on eurorack the last couple of years, I always come back to building fun cmos logic circuits.
I'm in the process of putting together some free electronic workshops for the public library where I work. I've taught some courses in modular synths, and soldering and wanted to reconcile the two subjects into a lunetta building workshop! the idea I have is to design a simple pcb, where students can learn some basics about electronic theory, soldering, and making sdiy objects.
I've taught a variation on this course before, using simple 40106 oscillators. My first experience with lunettta was through nicholas collins handmade electronic instruments, so I followed that model. But I wondered what other circuits could be taught in this kind of workshop?
TLDR what are some interesting lunetta circuits that: are low parts count, make interesting noise, or teach something interesting about electronics. Any guidance would be greatly appreciated!! |

Thanks for the quick reply Steveg! These are all great suggestions, I even remember building a few of these on breadboard a couple of years ago. The Nandulator came to mind as a possible project idea, because of it's low parts count, and only using a single IC. One of the issues I had with demonstrating the 40106 oscillator is that the results aren't exactly musical, so it was a bit hard for absolute beginners to relate to. There could be similar issues with the nandulator.
I think maybe my favourite contender so far is the opus 4052, due to the simple design, and musical results. Although explaining some of the circuit functions would be a significant challenge to a group of beginners.
Lots to think about!! Hmm I think it's time for a deep dig in the electro music archives to see what else I can uncover. |

I would at least choose a circuit that has some patching options (digital in-/outputs) so that multiple circuits could be
connected together at the end of the workshop. I don't know how it will be setup but I've seen photos of workshops
where participants are seated around a large table. If it is something like this (although not necessary) it might be fun
to have some sort of modulation source in the center, a simple counter like 4017 or 4040 could already work. Also
LDRs for pitch/tempo control are always fun (could be combined with the modulation source idea).
As for circuits, I expect you've already seen them but the fun with sea moss page has some fun little circuits. _________________ "My perf, it's full of holes!"
