Which are the most common/useful ICs/resistors etc? |
|
|
Hi!
I'm just about to dive into the world of Lunettas having ordered a couple
of components for all the "Fun with Sea Moss" experiments, a couple of
breadboards, pots, wire and such.
I am wondering what ICs and resistor/capacitor values are the most common
in your setups i.e. the ubiquitous 0.1/0.22uf capacitors, 100k/1m pots,
100k/10k resistors et al. I'm trying to compile a swiss army setup for various
lunetta experiments basically and want to know which items are suitable for mass ordering |

Whoo-Hoo! Welcome to the fun
I used lots of these...
100 k pots
1 meg pots
1 K resistors
4.7K res
10K res
100Kres
LEDs - Lotsa LED's.
1n4148 diodes
.1 uF caps
.47 uf
4.7 uf
10 uf
CMOS
CD40106
CD4052
CD5051
CD4024
CD4094
CD4015
That said...use what you've got. There are not many critical parts
Look forward to seeing and hearing your projects!

Thanks for the tips!
I'm leaning towards the male header/dupont jumper wire route myself
for making breakout/patchpanels when things eventually end up in a
project box or two. I thought of making a couple of input/output sections
on a matrix board and wiring it up with the corresponding intestines of
the noisemakers, then it would be easy to just cover up the unused holes
by printing out one large sticker with a legend so you know what is what
(even though it might be more interesting to let all the pins be anonymous).
The header/jumper approach lets you escape the economical hazards
of going haywire with banana plugs/patch cables and the likes and lets
you fit tons of things in a small space. |

Oh shi-
I want to call in sick the rest of the week, got a million packets in the
mail today. 5 breadboards w 5 bundles of wires, 5 555s, 10 40106s, 10 4017s, 8 4040s, 10 4093s, 10 5051s, 50 leds, 50 led holders, 100 mono jacks a ton of capacitors/resistors and such.
The best part is that i've got 4 packets waiting at the post office and have 110 ics in the mail (i forgot that i actually ordered ICs/pots and went haywire).
Anyways, i recommend Sure Electronics PCBs for easy transferring breadboard
circuits to "real" ones, first their big breadboard PCB
http://www.sureelectronics.net/goods.php?id=426
and their small ones;
http://www.sureelectronics.net/goods.php?id=137
The latter can be divided into 4 pieces which is even more practical when you need small circuits. |

You'll find that breaking up those small ones will be good for Lunetta building. I had 100 tiny circuit boards made for that purpose and sold a bunch of them. Need the rest for projects. Good luck and have fun!

I just ordered parts to complete a Klee Sequencer and two MPSs. Since there is a quantity break on parts, I ordered extras so that I'll have a "stash" of stuff for experimentation. _________________ -- Kevin

Cool, have fun with the new toys.
Along similar lines I've been slowly working on as small a Lunetta as I can. It would be great to come up with a "Single Board Lunetta" type of thing that fits on one big protoboard with the pacthing done with jumper wires and the pots are trimpots. _________________ ==================

Maybe one could have a couple of strips of pots, each row with a different value and then add patch in/out points instead of hardwiring them?
It would be nice with a selectorswitch linked to different caps too.
Off/ontopic; Are higher cap-values usable for more percussive sounds, i.e. extending a pulse? |

The pots could come in handy that way but for your base oscillators you'll probably want to hardwire at least two or three. Since the majority of the ICs involved require straight high and low signals voltages between 0 and 1 will have more utility if you get into creating control voltages for something. See the super simple VCO and the Yet Another VCO threads, and the R/2R stuff.
The higher cap values will provide lower frequency ranges for your oscs.
A good place to start is to do the sea-moss web tutorials at
http://www.milkcrate.com.au/_other/sea-moss/
Once the osc and the 4040 are hooked up you have heaps of options to play with the inputs of other chips.
I'd suggest getting the outputs of a clocked 4040 into the inputs of some logic gate like a 4011 NAND, since with it's output you'll have more of a chance to create a less predictable series of ones and zeroes.
If you have a shift register try connecting some of your logic sources into it and use outputs for things like injecting voltage into a spare oscillator, and experimenting with different pins of the potentiometer to do that. You'll get strange pitch changes, and then you're off to the races.
Sorry for the wall of text. _________________ ==================

Does the voltage on the capacitors make a huge difference? IE, two capacitors at .1uF, one at 50V, one at 100V. What difference does that make?
Newbie here haha |

Both would be fine. That's the max voltage it can take before blowing up, so if you double your power supply voltage and round up to the next available value, probably 25v and up, should be ok.
Sometimes a schematic will specifically state needing a certain voltage of cap, haven't seen that very often though. _________________ ==================
