omg its going to fit
4 band multiple feedback constant q bandpass filter eq will fit into altoid tin
omfg
maybe

crossovers are typically 2 or 3 way, because phase fucking on 4 way is a bit to much
this is for biamps and triamps
EQ arent fixed so the phase fuck is variable
right now im going nuts with the Q =(
i hope 1.666 is the winner
1 too much overlap, 2 not enough blending
pfft, dsp

Posted by renesis at 12:18 | permalink | 0 comments


youre nuts, go research
you want to phase fuck equally in your pass band
filters are gonna phase fuck regardless
you try and time correct some shit, youre gonna totally fuck up other shit, not to mention the added noise from the involved extra circuitry
youre not shifting everything 180
only in the cutoff region
like, youre delaying the same in the cutoff regions
where they overlap
so it basically is time corrected where your signals are audible and overlapping
the not without fucking up other shit
pro shit is 24db/oct linkwitz-riley
um
no
thats an eq
not a crossover

Posted by renesis at 12:13 | permalink | 0 comments


omg
the crossovers are gonna be cake after finishing the eq
4 poles
24db/octave
linkwitz-riley alignment, biashnieah
yes but perfectly phase fucked

its compensated
it it was .0002 on the x (not a typo)
.003 or so on the y
well, it makes sense, almost
but it hard steps at .00025
and it soft steps at 1/8 that
i guess pwm chopper drive or something, dunno really
it sounds alot smoother with the microstepping tho
but the aluminum shit i was doing, uncompensated backlash, was within .002 and .001 on some parts
you can machine so that backlash doesnt matter
if youre using dials on manual mills for any kinf od reliable measurements, you have to know how to

preamp is a single pole 10Hz - 40KHz bandpass
and the buffers are going to be 5Hz - 40KHz
so its like, standard per-octave EQ, + subsonic and ultrasonic
fuck debian
if you want to run current shit run slack or gentoo

and for two way, you just leave half the board unpopulated
omg
yeah sure
actually, theres JACK based stuff for linux would be better
i didnt get it at the time to do anything useful with it
cuz i was so n00b at everything
but its just modular synth parts

nice
damn
now i have to select values, adjust 'pots', and do again
yeah
kinda can
PWL
actually, you can somehow feed it wav file direct, i remember seeing that
im like, let me run a test, change values, run same test, change values, same test, one plot
then i can like, hit go, have lunch, talk to buddy on phone, clean room, then check my graph

im doing a sim of a 21 opamp system
!
WILL LTSPICE DIE!?
i dunno yet
i gotta go thru and select values for all the caps and resistors in the filters
heh, prob like 20 or 30 min
i wanna do with as few caps as possible, but keep the the resistors in the 10-68K range
i can use a set of caps for every pair of amps
and then use the same 4 resistors for all the filters
hopefully

dont touch it too hard you might crush the led

Posted by renesis at 05:20 | permalink | 0 comments


he doesnt wanna do smps
it gives him the ph33r
he does it its a power loss and futile
use 4 resistors in series parallel
or use two resistors of twice value in parallel
or two resistors of half value in series
you prob dont have a ton of .5W resistors either
yeah, that too
throw like 2K on there in parallel, itll prob get them under .25W dissipation
if you dont wanna unsolder shit

Posted by renesis at 05:10 | permalink | 0 comments


ur doing it wrong =(
yeah
you have base resistors?
they need base resistors
oh
yeah theyre integrated on some
how much current are you doing?
20mA x 7?
why not
20mA * 10V = .25W
thats too much
youre burning your resistors
dude
275mW
youre burning the resistors
build an smps

macegr: okay so 4 band EQ is kinda lame
macegr: but 12-band per-octave EQ is sexy
no audiophool can complain
so im do three eq tin, identical design, but diff passives
do rane style graphic EQ filters
from 12.5Hz to 25.6KHz

okay UPS should be here in the next two hours
im asuming an led toy
he just hasnt filled in all the leds
yeh
me too
why so many resistors
oh ok you are adding more
im like, did you only have 22R resistors or something

Posted by renesis at 04:01 | permalink | 0 comments


did they get reasonably priced or something?
i believe for a few months
but they been backordered for ages
naw
its better than an rx8
rx8 is trash
on so many levels
well, how does that remind you of trash, thats kinda nice =(
its more like an elise
bit more conventional in styling, but its basically an elise
yeah theyre selling them
but theyre just filling orders for the next year or two probably
like, theyre production trim, they just dont have enough, haha
yeah, its like elise body lines with ferrari lights
straight on, it looks like a japanese ferrari

you mean non PayTV?
blackmoon: electronics is so neat
i do maths
then i build stuff
and then it does what the math says
hmm?
dude if something is turned off, or without inputs driven, its undefined

Posted by renesis at 03:32 | permalink | 0 comments


because preamp needs 680nF for the 10Hz rolloff
so im gonna do two parallel 680nF for the input of all the other units after
so its like a 5Hz rolloff with same load
meru_: because itll float, and drive its input randomly
transition is when cmos eats the most power
so if its picking up some random high speed noise, it could be flipping the output constantly, eating power for no reason
and generating more noise
i think that falls into my first reason
self generated random high speed noise
well, i guess its less random in that case
actually its totally nonrandom

fuck knows man
he wanted to pulse standard LED at 100mA, theyll prob just work for a couple weeks anyway
2 years for LED PWM has to be some kind of record tho
like, i felt bad because it took me an hour to code because i had to learn LPM instruction (loading flash data to regs)
wavetab based, all he had to do was adjust my wavetab to do his project
shit was like 20 lines of code, including all init
instead he banned me
nice, parallel 680nF 0805 way cheaper than 1.2uF or 1.5uF

thats how i do it usually
why wouldnt it program
the electrons jump along the wire to the little tray
electrons come front the negative end
thats shit better have more than one LED
3r337ness = LED count.

okay multisim > LTspice at simming pots
i dont think LTspice even attempts
maybe there is a way to script it so it runs AC analysis, changes some resistor values, does it again
i cant afford multisim
so i think my mom is slinging nicorette or something
she got like hundreds of $$$ of it in a ziplock baggie in her bathroom cabinet
and i know she dont use it
maybe she slings it to the kids where she working

UPS running to a door, hitting a doorbell, and sprinting back to the van with your box is a common story here
tho yeh you only really see it happen to other people =(
i told them to stop because they just chuck everything onto the porch
and its a 20ft throw from the street or a 15 foot throw across the court yard into the inside balcony
also they dont leave a note
so ill be all confused because shit says delivered but i cant find my package
and it kept fucking up books and shit
2nd story =(
they have to hit the bamboo screen hard enough it doesnt just bounce the package back
so yeah, no more of that
http://www.20sim.com/webhelp4/library/iconic_diagrams/baxandall2.gif
mr elliot did that with 2 caps!
you have to put the domain too

Posted by renesis at 00:56 | permalink | 0 comments


(tho normal graphic EQ without the constant-q filters dont do this at all, so you can argue that those arent very graphical either)
haha, k
HA
i now have the local UPS hub number
ph33r
theyre not public
you have to call the 800 number, and get them to get the hub to call you
calling the hub fastest way to gaurantee your package dont do anything stupid like dingdong ditch

Posted by renesis at 00:51 | permalink | 0 comments


so like pot, attenuator VOLUME, unity to 12dB GAIN, +/-12dB BASS and TREBLE controls
and im considering doing a 3 altoid tin graphic EQ, 12 bands, multiple-feedback constant-q active bandpasses
so it would be a bass tin, a mids tin, and a highs tin, 4 knobs/filter sections each
identical design, just the passives on the filters are diff
with knobs and imagination!
i can fit slide pots, i dont even think the tiny ones =(
but yeah, if you can see the knobs pointers, pretty damn graphic to me, as far as interface
and then the EQ curve supposed to replicate the controls

Posted by renesis at 00:46 | permalink | 0 comments


*call
okay so i got the preamp down to two opamps per channel, using some hax0r baxandall's filter network
well, kinda
because mr elliot had his own simplified variation of the circuit, which included extra feedback components for easy adjustment of tone control ranges
so i used his simplified version, with no funky feedback parts, and then adjusted values till i got bass/treble curves how i wanted

Posted by renesis at 00:41 | permalink | 0 comments


use flux
okay, usp is all spammed at
fuckin hate this bullshit, i hope they called non blocked so i have the hub number
