So I've been browsing around for a little bit.. but I'm totally missing some fundamental concepts about Lunetta's and where to begin. Can anyone suggest somewhere to start? A forum thread maybe - or a particular chip I should buy and breadboard? Or maybe just a really nice, simple, elegant circuit to try? I'd like to get my feet wet - but am a bit overwhelmed by the amount of circuits and ideas here! Thanks!

This is a really good place to start:

This guy really helped me understand what's going on in Lunettaland, even though I am still learning.

First you're going to need oscillators, lots of them. Either inverters or Schmidt triggers should be you first chip investment .40106-easy and popular, but can be hard to find. 4069, easier to find, a little hard to work with. There's a Schmidt trigger chip with fewer nodes than the 40106, but I can't remember its part number off hand. Standard 555s, 556s and 7555s also make decent building blocks.
Considering the range of functions your oscillators need to provide (from
-s l o w l y- advancing the stage of a a shift register to driving dividers at rates high enough to be audible) you're going to want to build as many as you can in ranges from 1 tick every few seconds (or minutes) up to stuff in the inaudible 20mhz+ range.
Stock up on 4051 multiplexers. They tend to turn up in most "sequencer" type circuits. They're really useful for stepping between sources. Beyond that, just wire stuff together and remember that when our machine overlords finally claim their rightful place over humanity lunetta builders will be offered the privilage of being eaten first.
Logic simulation software -should- be the ideal way to sketch out lunetta circuits. I've yet to find any freeware that really fits the bill but I suspect it's out there somewhere.

Hi - welcome to the fun.

There is lots of Lunetta stuff here;

Go ahead and ask questions - we'll answer what we can.

Welcome!

All of that is good advice. Have fun with it and you'll see opportunities for interesting applications pretty soon.

EDIT:

Oh yeah, try to see each IC as being a functional block. It has inputs and outputs. Think in terms of inputs and outputs. If you can understand that you can learn the basic functions of ICs in that 4000 family.

This helped me a LOT, there's a Java app that will pop up:
http://falstad.com/circuit/
Dig into the menus and you'll find some great visual examples of logic functions.

Here's another thread of advice for new Lunettites.

thanks bruce

I've been trying to register to the deathlehem forum in the last few days, but as soon as I point the browser to it it says that my username is banned, though I've never actually registered one ?!?!

anyone else is having this problem??

Shocked

I think There were some spam issues - and a range of IP's were banned.
Rich has been working on getting it all fixed...

It's not you, I think there's something that needs to be tweaked with the ban settings over there. I'll try to get a hold of Rich and get him to look at it.

Looks like Rich has sorted out the problems, so hopefully everything will be fine now.

Yessum folks! It looks like it's all 'otay' now, since I restored the backup from May 21st. Surprised (Major messages lost, but ..... )

The BB's been running fine for 2 days now with those who'd been 'banned' (apparently) logging in now, with no troubles. Smile

For those here who've been through it - major amounts of apologies for it! I've not a for sure clue what it were, but the Restore seems to have taken care of the problem, VERY thankfully! Surprised
