EM2010 Lunetta Workshop after support

[electri-fire]

Thank you Kevin and Eric, Mike, Kevin, Rebecca for attending the workshop.

Things that pleased me:

I "think" everybody got "some" idea of what Lunetta building is about.

I have gotten across the "Les Hall Neatfreak Staple Method" for breadboarding (though Rebecca has been reluctant to pursue the method ) .

I do recommend to use the staple method when keeping your Lunetta on breadboard. Some of you will be transferring circuits to soldered versions, in wich case it's less of an issue.

Things disappointing:

-I planned to show you loads of other things, but didn't get to it.

Reason for this not having happened:

1-Lack of time. We could easily spend two afternoons doing this.
2-Chaos. Noise. People coming in and out. My inbuilt tendency to being disorganized. Next workshop I'll be locking the door .

-Not doing the Lunetta Maelstom. Due to things I thought being unfinished. Kevin and Eric had been tinkering at their boards on their own, so in hindsight we could have done something. Make a racket at least.

Lunetta building and using takes some getting used to. You'll have to invest some time in discovering the possibilities and overcome technical issues.

The bright side: We (electri-fire and the rest of the Lunetta community reading this) are here to assist you with your Lunetta builds and technical bottlenecks. You'll be posting cool setups and sounds in no time.

Read the Lunetta Forum. Let us hear how you're doing. Thanks again.

This CMOS pinout collection:

I had printed out for you as a reference , but I left the prints at home and forgot were I downloaded it. So I got you a different set of prints, but these have more IC's and are more readable.

This workshop was very useful to me.

For starters, it was helpful to learn organized methods for laying out the power and ground busses and to learn how to populate the breadboard such that one can easily transfer a working prototype to a schematic.

I've already put this to use -- the Envelope Generators on my Aries synth pulled too much current and I designed simple voltage followers (with large input resistors (1 meg). From breadboard, into Eagle, and an etched PCB was a breeze!

The beginner Lunetta thread speaks about pulldown and pullup resistors however the workshop made it clear as to their purpose and implementation. While one can read about things, it is often useful to actually see it being done.

I am now designing a PCB that simply accommodates a "virtual" 18 pin socket with corresponding traces and pads and space for other components (such as resistors, diodes, and pots). Why 18 pin? The reason is so that I can place 14, 16, or a pair of 8 pin sockets.

I envision a Lunetta that is a kind of "modular synthesizer" wherein each chip is a "module". I plan to utilize banana plugs and go for something that is not too hard to transport. My ideas are subject to transformation -- once I get into the project I'm sure I'll think of things that I can't anticipate at the moment.

Eric and I both had a great time and look forward to next year. By golly -- we will manage a Lunetta concert next time!

Man I really wish I was there to join you guys, ah well, maybe next time.
