Oh, Matthe, I'm unfamiliar with the 4051 chip, can you explain it for me? Maybe I can do something with it...

OK, the low-down on shipping is this: It's $8, a bit high in my opinion but my friend Daisy who I'm evangelizing into doing kitting for me with this as a practice starter, says you gotta consider gas and time and yada yada yada...

Yoda? May the farce be with you! So anyways, please calculate $2.50 per board plus $8 shipping. you can pm me your address and the paypal email identity is lester.hall@comcast.net. We plan to do a mailing later this week.

May all your Lunettas sing sweet...

Les

Very Happy great news! Is the $8 worldwide?

I'll PM you in a sec. Les. I'm in for 10 as well. I'd really like to 'posh' up many of my lunetta ccts. I've learnt so much in the past few months I'm looking at some of my early modules & shaking my head at the poor quality construction Embarassed

I'm not sure, DGTom, but I think so. wmonk mentioned that Bill shipped him some parts and they were marked $5, so that's $8 including gas and time as far as I'm concerned. If you live in nowhereland, lol, then it might be more but let's use $8 as a catch-all. Heaven forbid I would ask you for additional paypal payment if it gets expensive for some reason. Later man!

It has one input and eight outputs. It can also be used in reverse, that is, send one of eight inputs to an output.

Three inputs (ABC) determine wich of the eight connections is made.

The 4052 is similar, but has 2x4 in/outs.

Droffset used a 4052 in a circuitbent instrument:

Here's a thread: http://electro-music.com/forum/viewtopic.php?highlight=4051&t=23972

RF (Bruce) has one in his Lunetta: http://electro-music.com/forum/topic-30479.html

There are some schematics that use it: http://milkcrate.com.au/_other/sea-moss/

Ah, I just did a rearch on the forum and there are loads of hits.

OK Matthe, I get the CD4051 chip now, an 8:1 mux/demux. This could be a very powerful chip for Lunettas because it routes analog as well as digital signals. I'll order a few of them for playing around with.

Oh man, this is so funny. I drove my friend Daisy to the post office to mail our the circuit boards and we did get them mailed out, but the whole thing was like some comedy show called "The Two Stooges go to the Post Office"! Hahahaha, between the parking fiasco and the one-way streets and Daisy's comedic stream-of-consciousness chatter it was chaos. We also didn't understand the postal rates, what package to use, how to pack them, and well, suffice to say it was pure lunacy at it's finest!

The good news is we got all three orders mailed (10 circuit boards each). The bad news is that the postage was more than I thought it would be. Maybe there is a cheaper way to do international shipments, but a priority mail envelope is $8 more than I thought it would be. But no worries, I'll just absorb the cost and use the correct figure in the future. For the time being, unless I can figure out a cheaper way to send internationally, shipping will be $16 outside the US and $9 inside the US. But I think most of those who wanted boards have them now, or will when the package gets there.

In other good news, I used the paypal funds that paid for the boards to buy parts for building eChucK sculptures. Hopefully those parts will arrive by next Thursday. There are two people who want to buy eChucK sculptures from me, so I ordered enough parts to do three Chiphenges of different flavors and two Tie Fighters (adjustable ring oscillators) plus one speaker module for demonstration / testing purposes. I hope it all works out, but it will be fun regardless!

Phew, that was enough stress for one day in my book, but it sure was fun stress. I Hope you got a laugh out of my little post office adventure, and I hope you enjoy the boards!

Les

Thanks for the update, Les.
These should be a lot of fun. I have not decided exactly how the boards will be used but expect it will morph into something interesting eventually.

Tanks for doing this - and thanks to Daisy, too.

Hey, guess what? UPS delivered the Digikey package two days early! So I decided to create a test board just to send it to Howard so he knows what I'm talking about. The photo below shows the soldered board on a keyboard as background, and also shows two 8-pin screw terminals of a different style.

The good news is that everything fits in the holes, yay! Even the screw terminals fit. The bad news is that the holes are kind of large for the chip leads. That's OK, but what I did by mistake is feed in too much solder and the solder built up on the chip leads in an ugly way. So I just used some solder wick to remove the excess and then didn't' feed too much solder in on the rest of the pins.

So there is room for improvement here. On the next batch of these little dealies I will make the outer columns of holes the same size they are now, or perhaps a hair smaller, and make the interior holes a good bit smaller. I might make the board one row taller too, not sure about that.

Anyway, success! The parts fit in the board and solder up just fine. Please let me know if you have any other suggestions regarding these boards, thanks.

Les

I started playing around with the eChucK Lunetta boards now that Karplus Strong is ready for 1st run boards. The first module I made is called "Speaker". Speaker isn't too smart, he just plays whatever audio you send to him on his speaker. He does have a volume control though.

In front of speaker is a partially assembled Tie Fighter, a five-stage ring oscillator made with thumbwheel pots.

In the background is my Karplus Strong prototype.

I wish I could find those 9V holders locally Sad

My boards arrived today Les! Look great! Tomorrow I'll have a fiddle with a few, they may end up being the base of the NAND Osc. Data Resonator I'm building for a friend Very Happy

Cool Thomas, I hope your friend will enjoy the gift. Mathe told me that I sent him an extra 10 boards, so now he has 20! OOOPS! Oh well, no skin off my back. May as well share the wealth eh?

The eChuck Lunetta Boards Les has ordered differ somewhat from the version 2 he posted.
The boards are really cute, and pristenely made. It is hard to see the traces, as they almost have the same color as the board.
I editted it to how the boards are now, I think it might come in handy to document any schematics on it I/we might develope on it (until I learn to use Eagle that is).

I finally constructed my first Lunetta! It is Tie Fighter, a 5-stage ring oscillator (not ring modulator). It doesn't sound all that special, it's just an oscillator, but it was an experiment in using the little eChucK Lunetta boards for something. I might make these little projects into a beginner's Lunetta kit...

What is a picture without sound? Laughing
Cool Inventor! Keep 'em coming! Can you explain why you called this the Tie fighter?

I'll have to make a rcording. Tie Fighter is called Tie Fighter because he looks like a Star Wars Evil Empire spacecraft a little bit. What may be difficult to see in the photo is that Tie Fighter has a central horizontal board and two left and right vertical boards, just like in the Star Wars movies.

Heya Les,
I've been a little out of touch for a while but if you do another run of boards and stuff send me a PM and I'll be in on it.
