oy, another noob... Subject description: saying hi after aeons of lurking |
|
|
hi all,
yes, the time comes where after a while of lurking the first post is due...
i've stumbled across this board (and other lunetta/cmos) pages when looking into the general audio.diy matter, since - in the long term - the plan to go modular is underway...
I have documented some of my first forays into electronics and lunetta-inspired stuff - on my blog, including some sound-samples... probably not much amazing stuff for the veterans here, but sometimes even the simple, well-known can inspire (i hope)... enjoy it here:
http://www.blog.ivorybunker.com/?p=38
(yes, there is a lot about the non-lunetta chua circuit first, but heck... if you excuse my swearing, plz.)
well. i'm sure i'll be having loads of questions, so... well, looking forward to being here!
(ps: i've also posted a "hello word" in the general section... the info there is basically the same you get if you follow the links in my sig. cheers)
cheers, th _________________ ~~~

hey,
thanks for the welcome.
things came other than expected, so i didn't have time to work on much the last couple of days. or post here. things looking a little less hectic the next couple of days, so I hope I'll get something done.
one question right away: does anyone have some links to good tutorials on how best to transfer your circuits to perfboard?
I looked around quite a lot, but haven't been able to find something quite as comprehensive as I would like...
thanks _________________ ~~~

the best way to do that i know of is to get the breadboards and matching perfboards from Jameco. 1 to 1 correspondence of traces makes it easy.

thanks for the hint, inventor. thing is - i already got a few perf- and stripboards lying around... did find that (while stripboard magic can be nice, but also awkwardly slow) sketching things out on a notepad row for row is a) a great help and b) (for now) probably fastest.
i've been, btw., trying out a few of the circuits i found amongst these pages on breadboard recently... hoping to find the time to post some pics/sounds of those and my (eagerly awaiting me finding the time to do so) planned first soldered builts... _________________ ~~~

I work on stripboard. I draw everything by hand first on paper. I used to draw all the holes between the lines on note paper... then I made stripboard paper! It's here if you would like to print some out:

I draw on it in pencil so I can erase changes easily. |

thanks minus,
this comes in really handy (or will, once i got my toner refilled...)
i tried diylc for a bit. nifty prog, thanks artifus...
atm i'm still a bit too impatient for it, it seems- the hand to paper cpnnection works better/faster still, but for more complex layouts...
haven't had that much time at home (long shifts at work, which luckily allow to learn some theory, but taking the soldering iron and all with me doesn't work...)
did do some breadboarding, though...
preparing audio (and some way to create a schematic - yes, also slow with learning eagle - all these progs seem very unintuitive to me atm, coming from music apps... i keep waiting for the progs to give me some signal. in reaktor, for example, i can test my circuits 'directly' here it is from testing on breadboard to drawing to planning/layouting... well, i'll get the hang of it sooner or later. an interesting experience nonetheless) - oh, was that a long sentence inserted, anyways, planning on posting some more on an idea i've been breadboarding last night... (the idea was) a cmos sample and hold...
here's a little preview of the breadboard:
/1 40106 as clock, and one (diy vactrol controlled) audio osc 1 40106 using 4 gates as osc. feeding into the 4042 a 4040 and a 4042 w outputs routed to a resistor-network which 'feeds' the vactrol led... the idea was to create a sample and hold -
the 4042 has 4 ins each with 2 complementary outs strobed by a common clock... so by connecting these outs to the resistors (in some arbitrary order) you'd get different 1s and 0s at the different pins which should give you varying voltages at the various "pinouts" of the resistor-array...(i might be wrong there)
i realized 2 things - 1 - of course there will not be much voltage variation if i just take the cv from the same pin of the resistor array (basically 4 different voltage levels, unless i'm wrong)... so i was thinking (fell asleep before trying) - if i connect the pins of the resistor array to the ins of a 4051 and have those switched each time as well, i should get a few more different voltages
2- i might have misunterstood the 4042 description - it says that the outs q and notq 1-4 are set at the rising edge of the clock. but it sounds as if they don't stay at 1 or 0 but rather just put out whatever the clock puts out. - anyone know more on this?
if so, i think that also could be solved by having the oscillators creating the "random" ins 1-4 run a bit slower than the sample and hold clock...
not sure if all this makes enough sense for ideas/criticism without having a schematic, but anyways... any feedback is very welcome
i need a 4051 or something which (at the same clock as the 4042 varies (as randomly as possible) from which pin off the

more pixs - sorry for the blurryness... (not sure if it's uploading both - one should not be that blurry)
if anyone's curious - the circuit on the small breadboard is the very simple vcf (should anyone need the link i can search it...!)
