lordpil's blog
man i need to connect, i hate this being wide awake shit
i did sleep
you mean again?
im trying to remember what i do for fun when im not doing electronics
Posted by renesis at 18:36 | permalink | 0 comments
you could have went to school for electronics engineering and learned just as little
everyone i know who i decent does the shit on their own time
pretty much all the time
shit i think its closing time in china

damn
i thought this channel was like the cream of efnet intelligence
like, #physics fools prob just playing with calculators all day
wtf grand father
electronics IS most technology nowadays
naw cuz theres def some mechanical and chemical shit going down too
but that stuff is not possible without electronics
modern technology doesnt happen without electronics
hell modern society doesnt happen without electronics
yes
30 years ago is fairly modern

meh at medical
overpriced
here, theres 4 kinda of weed
swag (shit) mids (no market or reg prices) regs (the chron) and kush
like, $200/oz or so
i was getting OG kush for like $275 for a bit
but that wasnt consistent, gone now
ha nice
food is a bit much tho
like 2 or 3 days in, its like the whole entire world got slightly weird
but i cant figure out why
pfft i have too many issues with girls to even be phased by shit like that
i dont have a prob with it if she dont
were not together
good luck on that tho, she all into me =\
litefreak: man stfu already
ha my ex is art school student
masters done, on her MFA

for $200
awesome
i likely wont be traveling with any
i hope you guys dont smoke swags

okay so forest moms specifies dimensions in Mils
er, mims
and prof is trying to say its an invalid unit
either macegrs or im getting a room
if my exgf decides to go see make, she gonna meet me there and we might split a room

theyre saying do one panel request for each board
Hi randy,
Sorry , it is a mess.
i wont what 'it' is
er, wont/wonder
ok
so i ask for the same thing
but individual panels
sucks because i just wanted single units of a couple of these boards
Posted by renesis at 17:17 | permalink | 0 comments
ugh, they dont wanna panel them
hmm
Or ,you send us one pcb's gerber file ,we paneled it to a panel ,example,2*3 ,5*5 , etc. :)
i think what theyre saying is i should get like 9 diff quotes
no
theyll panel single files
they wont do multiple designs one panel
i have to do that myself
they prob just have an option on their fab thing to do a matrix of the design
diff boards?
well, i think their issue i having the boards on one panel
Posted by renesis at 17:12 | permalink | 0 comments
i have it, its very good
based on a 2 semester electronics course for grads
very practical
'good circuits' and 'bad circuits' example at end of all the chapters
tables with generic part data
math is almost pointless until you can design
like, you need to have something to put the math on, heh
its kinda weird like that
like in the beginning it was all maths
because its not like you could do your own circuits so you just could do analysis
yeah me and macegr have booth
we on the make website, good enough for me yo
im doing led grow light (lowlevel success, so far)
and an altoids audio system (amazing if it works on this schedule)

he doesnt want the answer he wants you to make his function work
and strife
dongs and strife should be a broadway musical that i dont go to
rockshox has difficulty dealing with other peoples opinions
much like the avrfreak, he tends to label anyone who disagrees with them as some form of cognitively challenged
then ironically proceeds to make himself look like said label
haha
man that guys hates me soo much
was like, obsessive levels of hate
like, he was a better machinist than me, doesnt own a machine, better avr asm coder than me, but he still cant access mem
oh neat
thats from microchip?
or 3rd party
oooh
hehe beta testing a uC compiler is prob loads of fun
Posted by renesis at 16:11 | permalink | 0 comments
people think learning c is a shortcut that will let them run a uC without learning the hardware
anyway, you CAN do what stu suggested
you just need to use pointer and add a constant offset
i dont think thats what you wanted to do tho
Posted by renesis at 15:57 | permalink | 0 comments
you can use ldi and sti to access locations immediately, but without post/pre incriments
also c compilers usually do some way silly shit on interrupt entry/exit
so what should be like 4 opcodes of overhead is prob like 20, for no reason in most applications
sry 4 cycles
so yeah, fuck me because i want to learn hardware and make shit happen
instead of learning stupid details and syntax that have zero to do with digital electronics
um
i dont do c
PORTB = value;
fuck you, you said something stupid, and now you pay for it
youre obvious frustration or annoyance is only fuel for my fire
^-e
damn missed
Posted by renesis at 15:52 | permalink | 0 comments
all registers are memory locations
same ith peripherals
they dont share address space
its in the datasheet
see like wtf is memset
theres 3 pointers besides stack
theyre the top 6 registers, in pairs
all you do is write the mem adress to pointer, which you already defined as a variable and data length of
and then use ld, st commands
Posted by renesis at 15:47 | permalink | 0 comments
because youre a good programmer
and im shit
you cant even write to a port that way you want
or get data into ram
sorry you made an perfect example of yourself about why C on 8bit uC is dumb
unless you can do it in asm anyway, then maybe c is useful as shorthand for asm operations
but honestly it just seems like itd get in the way
yeah thats nice rockshox
why you keep mentioning it?>
how do you even know im talking about it?
why you afraid of what the asm hax0r is saying?
stu programs in basic
haha
we have paper punch readers at school
in the NC lab
apperently back in the day, they taught paper program splicing
see but thats bullshit
because a) you need to do binary level c to make cool shit happen on a uC
b) i code in plain text, not binary or hex
so stfu
no ones talking to you now
you suck at uC, its ok
dont read that
Posted by renesis at 15:42 | permalink | 0 comments
my main files usually look WAY simpler than c files
because you can use macros, so main code is like:
deathloop:
do_this
do_that
rjmp deathloop
write to memory = load pointer, use mem load opcode
or just use the load immediate to or from ram codes
its like 3 lines
allocating ram is a single line
my god i swear the reasons c coders come up with for not learning the asm
what if the pins change, wtf
btw there is preprocessor conditionals, too
so you can write code that works on any avr with a few lines of conditional and a AVR_PART constant
or you can dick around in c
wonder why your code got so big, why you cant write to mem, and not have any clue how the mem and register adressing it setup
*is
you did
no
i think you read enough
right

asm #1
you guys spend so much fucking time on stupid code syntax
and trying to make the hardware do what you want
instead of just doing it
its kinda hard to take your 'c is faster' argument seriously
?
?
you can do asm portable
totally
all my code is with redefinitions
then change the .set or .equ line?
wtf
you guys are lame
do you think i code in raw hex or some shit?
um
.equ STUFFPORT = PORTB
.equ STUFFPORT = PORTC
.equ STUFFPORT = PORTA
omg im a genius, no?
yeah but youre failing
its not the hardware, its c
no datasheet gonna help you out
no im bitching about how lame this looks
um
my sam7 c shit works fine
and thats not libbed out
we did the lowlevel code
arm7 has insane 32b opcodes
avr has lovely opcodes
the ONLY diff, asm and c, is use of words like if, else, while, for, switch
which is all simple
in asm
if you can program for real
bitch
you guys have have compiler and syntax problems, on top of hardware problems
for no real gain
Posted by renesis at 15:32 | permalink | 0 comments
its the hardware adress for portb
wtf at var containing it
you cant write to the variable
its a constant
dork
you have a pointer?
why do you need the pointer
dude putting shit on port b in c is PORTB=stuff;
yeah portb is changed in the definition file
fureal

if you have a two channel scope, put ch2 on inverting
remember to use DC coupling
haha fuck maxim
working there in design is prob fun
bos: just use two adc, measure top and bottom of the shunk, or just the top if the shunt is grounded
subtract
done
if the shunt is low side, on the same ground as the uC, no really
*not really
you might want an amp too boost it for higher res
but you can drop adc ref lower too
high side you wanna use 2 adc or a diff amp
Posted by renesis at 14:51 | permalink | 0 comments
so fuck all that
i dont rag much for C
i did alot on sam7
its almost shorthand
like on that level, its pretty clear that most thing are integer values
if you dont know electronics, you shouldnt touch a uC
oh please what
thats fine, im not trying to build overpriced less functional shit
i can
i rag on engineers too
shiftbrite isnt a uC
modules arent uC
yes

just use a to92?

nice
soic to dip = sadness
soic isnt even harder to solder
the pi spacing is the same
when you account for holes and pads
hmm
i dont breadboard as much anymore
im like, schema/sim to PCB
breadboards are shit for noise and high speed
hai, im am your bank of random capacitive plates
i dont even know what arduino is

does it have proper DRC and capture?
does it have proper DRC and capture?
i think it had capture
=(
hopefully you didnt do any parts upside down or something
stupid girlcat is eating a paperbag
man i feel bad for harold

i wonder if anyone actually bench tested the amps too see how bad the opamps perform at that output
macegr did that with a big lcd and a projector bulb
hehe pics was pretty sweet

wtf
one is bidding with 3 days left at $18
my headphone amp BOM is like $4, after altoids and connectors and pot
with 470uF output caps
ha i bet cmoy isnt even output coupled, because the dual 9V
maybe $4.50 with pot knobs
and runs fine from 4 AA batteries
er, triple AA, thats what fits

is that the gif or png based touch screen?
i remember you talking about those like a year or two ago
ha neat

depends how much free time your running and what kinda of lookup algorithms youre using
like whats best
psi_: SD flash has an spi mode
kevtris has been fucking with them
he had spi working quick, i think he got direct paralle access working after a couple days free time
i would have added a comma and question mark
im going to get a panel and have them fill extra space with headphone amps
sell them on the ebay as NOT CMOY, BETTER
i still dont know how someone gets a datasheet opamp circuit named after them
sell headphone amps?
those little IC are awesome
also cmoy needs dual 9V battery
Posted by renesis at 14:16 | permalink | 0 comments
the crypto shit is like DAAAAAAAAAAMN
neat
yeh
okay so im going to do PSU and selector tins at home
tiny amp, mega amp, headphone amp, preamp, equalizer, crossover, and shifty breakin and breakout
8 with a 16bit mode i think
prob some of the peripherals
and maybe some extra opcodes
flash is $$$
not nearly as much, but its still prob the most expensive thing in it
way more flash inside than sram
*as much as it was
yeah, samples
i hack in asm, more flash = more constants
yeah
depends on your interface
you cant fuck with parallel ram for speed
for sound datarates, maybe anything is fine
rly parallel addy mem is prob way faster than the uC can push
spi interface might be slower, but if it can reduce cpu time, it might work out even better
Posted by renesis at 14:11 | permalink | 0 comments
how was that?
whats up with xmega?
whenwhenwhen
nice
okay maybe im soon
i dont think local dud even got back to me tho
how much?
like $200?
jezus fuck, awesome
i finalized the pcbs
i had to change the miniplug, digikey non stocked on me
i swear they had hundreds
so i replaced with shit they have 8000 of
and that i seen at all (without the stupid switch pin im never going to use)
yeah people buyin em out and shit
i think they got more popular or some shit
even more, i guess
or theyre having stock issues, which is kinda lame considering who they are
yeah thats really what it looks like

wow is it like, remote shell based or some shit?
haha @ via bluetooth
ITS NOT DETECTING MY BRAIN WTF [returns game]
haha ok
last game i bought, GTR2
had securerom
and wouldnt let me install
i had to crack and NoCD it
no even after i uninstalled everything
fureal
it might have been the 20 GCC environments, too
supposedly it freaks on dev/debug tools
yeah i have a legal license
i lost the fucking disc or something
i prob have it but wtf at looking for a cd envelope everytime i wanna install
s/lost/dont give a shit or need
Posted by renesis at 13:31 | permalink | 0 comments
me too
those are neat
the app is shit
do they take real board files yet?
for the miniboards
i should check
Posted by renesis at 12:50 | permalink | 0 comments
shit was ripped in half
they wouldnt accept an envelope like that
ha no fureal if i had to blame anything, it was the manner of packaging and the usps service used
was a reg envelope, reg postage
i mail anything not paper, im like, fat paper envelope covered in clear tape with bent cardboard internal structure
dont think so
dunno
Posted by renesis at 12:24 | permalink | 0 comments
jokes on you
envelope was prob already tirn by the time they intercepted it
talk to twingy then
anyway it wasnt torn

ac-130u: anything bipolar
ac-130u: you have to check the amp datasheets, but i bet +/-9V is okay
then you can run a vreg for the 5V for the headphone amp
ac-130u: you can do pretty good with opamp and a half supply ref
wtf 1' gap
Posted by renesis at 11:30 | permalink | 0 comments
for headphone board?
yeah sure
psu is kinda one off
its made to drive the main amps
you just need bipolar supply, pretty much any voltage
for the preamp
im using +/-15V but way less should be fine
depends on the amps
the headphone amp is just 5VDC
nice
i think the crossover board is gonna be easy to rework
Posted by renesis at 11:24 | permalink | 0 comments
ac-130u: replace the connectors on all my boards and submit to chinapcb

just need to do crossover and equalizer

these connectors are better
just not right now

no like it had bugs and all sort of living crap
worms and centipedes and little bugs
fuck that
whatever it had bugs and theyre putting dots all over the habaneros
and now the cactus name succulent has shrooms
they were little last night
they like blew up
next time im mixing my own soil
and no outdoor powerline nursury plants
yeah like old mulch soil from treefarm
unless they are shrooms that hurt stuff =(
i have kitties what if they eat them
ya rly
im about to abort
take some pics and trash the grow =(
its liberating

there was a few hundred before i think, heh
i dont want to do two order
tho i should check
i might get the pots from there
i dont see how ordering more is gonna save me any money
i dont care if its .24 instead of .30 a unit
more $ is more $
i got some 10dip signal ones coming from all
okay im getting the little ones
they have 8000 of those

hey but now i know what SJ and MJ mean in their part numbers
i new the layout was just too awesome
dude it was like, perfect parts
3 pins, spaced even, inline
you know, HOW YOU WOULD THINK ALL AUDIO JACKS ARE LAID OUT
looks like i have three options
man next revisions im putting mount holes
fuck this panel mount bullshit
yeah

even all has them
both

fuck i cant believe i gotta redo the fucking board
thank god i did connectors bottom and parts topside

timecop: i think ima end up trying out that 2 day rush shit
its first order so COD so maybe i dont give a fuck what it costs
i should be getting $900 grant money and then free money shows up first of the month
wtf timecop
its threaded miniplug
those things are like minor gold
this is a better pinout for pcb

thats me small
at like 220lbs
my friend is going away =(
the guy on the right
edgar is still here, he family people to, but john my bro from another mom =(
and like i dont really look a ton diff when im at 240lbs
some of the extra weight prob my legs from biking everyday, tho
haha
i miss wearing those pumas
i still have them i need to get them new laces
theyre camo suede
pumas are the best
nikes are usually too narrow and too much padding, adidas too much padding and too stiff
reeboks just fall apart
yeah shoes make huge diff
new balance is good
breakdancer shoes =D
i pretty much wear shoes in their classic running shoe style

pulse actually have a pkg called Bigfoot
so technical
im like 5'6" and 230lbs
well, 210lbs to 250lbs, depending on mood
i try and tell people im ft but theyre like, naw youre just big
which i truly am, but im fat too
i think they are in fat friend denial
tho like if a girl seen me nekkid is all like 'no ur not fat ur big!', then im cool with that anlysis
several girls, i guess
they are maybe in fat fuckbuddy denial tho

ac voltage source
you nead gearing
or just a brush motor and servo or brushless setup
kinda year
*yeah
itll be mad hoppy
gearing down a stepper is cool
i need to get a fucking business or personal loan and just buy a fucking gerber editor wtf
does it view or edit?
wtf eth cards mac
k lemme know if you find again
so they prob want my routers mac
which i can mak whatever i want
it checks?
at runtime
haha silly
i guess thats a good ID as any
you can prob edit MAC on most NIC too now, tho

timecop: devfs is deprecated
it worked awesome, sometimes
but it had major issues, and i guess the dev is MIA for years
now its udev
which if youre willing to learn how to write rules for, is pretty neat
it works cool
i like the realistic view of installed devices
fuck that filenode for every possible device bullshit
how is that proof
how is that him just not saying what is blatantly obvious regardless of who did it (bush and the wannabe illuminati crew)
wtf is poles/zeros
i havent used pspice since school
i like filter poles
i can get it to do ac analysis and transient analysis
and thats basically all i would use a sim for
you want to do ac analysis?
in ltspice you just set the voltage sources ac voltage value
and then you run an ac anysis sim
3600rpm ungeared is kinda fast for a stepper
theyll be too much tho
at mcmaster
theyre prob good brands, but you dunno til you get it
they dont advert branding

i think its time for a minipizza doubleplay
cat /dev/random
do it, increases system performancer
cat /dev/input/mice; is kinda fun actually
you it feeds your sheel all sorts of weird codes
you usually have to reset the term
i hate that
dev random to audio does almost nothing
chirps more than anything

wai no
just unclick that
and thats good
because it does everything
also 7z native is best compression
better than bz2, yo
serious, uncheck the box
winrar is bullshit
wtf
ive been using it as my archive app for years?
serious, no issues ever
unrar.exe is cli, fuck that
7z is lzma
the file manager is the same
lzma is better for most everything
i dunno how it compares with compression/unpack times
but it gets better ratios than bz2
which means its the best, except maybe shit like png and flac for specific media
flac beats bz2, thats pretty impressive
zip was almost a joke compared to both
i only use zip because anyone can open a zip

i have twezers for it now
$10 at the beaty shop while buying clipper guards
come to a fine sharp point
i got some good tweezers for $.99 there too
chisel style, so kinda works out fair
k i gotta desigm schema and route up the psu regulator section
fuck that
thats prob like .0625W
if that
dont die fool
haha traffic, nice
ah feal ur payne
dude the only accident i got into on the street was like at 2mph
i had clutch in and lifted of the brake while reading a map or datasheet or fuck knows what
traffic is like bathroom
i rolled into the car in front of me at like 2mph
it didnt even hit it, i like stopped against it
7z

i might get a panel of just power amps and headphone amps
and try and sell modules
rev2 cs audio gonna be all breakouts, no connectors
too much problems with stock and routing
so make em small, optimal, with pad and wire breakouts
but so they still fit in altoids
but the amps are final, they are in that style already
yeah the headphone amp you can do in 5min dude
you prob do shit 10x more complex at work
all the amps really
maybe longer just to be extra careful about part placement
all 0805 gets tricky, heh
yeah
those are good chips
yeah
easy
0603 is like, minimal challenge
0805 is cake
0402 sticks to the iron and no place to hold with tweezetrs
heh
yeah but you can hold down with tweezers easy
0402 is like, hai i am your .015" resistor body
Posted by renesis at 07:56 | permalink | 0 comments
they should do maybe half that at max power
unless i set them up for like 150% max power, which im going to do
its neat how i have degrees now i can do things like that and say its 'research'
all from smps
it gives you a reference
if it tests good i should give to ST like 'hai, this is better than ur datasheet ref board, sirs'
their shit was all huge
sup niggy
so like
10 boards, 6 days
2 being massive for the space alotted
prob tomorrow
usps came today
i got my minidin8 cables
unless he left them in the mailbox
(my key dont work, have to wait for family peoples)
i dunno
i can do it at home for free
im doing psu and then im getting a quote
but its like prob 3 or 4 day rush shit
and some expedited shipping if they got it
so prices will be bit offset, heh

smt
0805
its got 470uF output caps
maybe $1 for those package
for both
but you have to buy 5
i think
yeah
r2 is input impedance
yeah basically
C5 and R5 are the low pass pole
C2 and R2 is your input hpf
well, yeah but id just do an input attenuator
to keep gain/performance consistent
i have a preamp altoid if you want volume/gain/treble/bass knob action
i gotta go do layout for psu
i wanna do 5A max rails LDO and 500mA 7815/7915 regs
2 5A max rails
one for the big amp, one for the two little amps
Posted by renesis at 07:46 | permalink | 0 comments
fuck a cmoy, wtf kinda of signal amp abuse is that shit
non of those opamp datasheet specs are relavent when you drive an opamp like that
well thats not true, the graphs that say that amp will suck when you drive it like that are relavent
i just pasted again =\
yeah
dude like 20 lines up
you put an input miniplug, and output miniplug, and 6V max on it
thats it
so like, $3 total including batteries and altoids, im guessing
you cant really do those homebrew without some kinda hack
because of the two vias under the cap
im going to try anyway tho
yeah
its dual
easy to change gain or input bpf roloff
yeah is just an inverting amp
but they did the single supply bias inside
thy break out the bias point to a BYP pin so you can decouple it with any cap you want
Posted by renesis at 07:41 | permalink | 0 comments
prob typical hysteresis type stuff then
the output wave voltage would look COMPLETELY fucked up
but you should get a good clean signal across a sense resistor
speaker is a transformer almost
magnetic to mehcanical
instead of magnetic to magnetic
you need transformers to boost current
because tubes cant do current
at all
like almost nothing
thats why you need HV tubes
and transformers
to turn high voltage into high current for low impedance
fuck tubes
they were good because we didnt have silicon
now theyre good because people are dumb and pay mad $$$ for them
ac-130u: so yes, no?
want one, ill make sure to order an extra headphone amp
i already pasted
its based on semiconductor corp ninjas

i even put an input bandpass on it
thats not in the datasheet yo, thats some ren special shit
its a $1.50 chip with amazing specs
Posted by renesis at 07:36 | permalink | 0 comments
dude his designs is a datasheet opamp circuit
with some output imedance added
buur brown high speed is great for like, video processing
serious you can make good audio shit out of LM741
whats transconductance amps?
class-G or something?
current feedback audio
AB + current feedback is supposed to be like the grail of linear audio
because speakers arent voltage mode
theyre coils, magnetics, its current mode
so if you amplify the signal voltage into output current, you get like precision speaker movement
but
you have to use massive voltages to get the speaker ti change directions
so its not a typical voltage gain is your rails thing
you need massive headroom so the amp can hit the speaker with mad voltage to change its direction
professor: yeah but how powerful?
im talking like, single src sub duty, around 200W ideally
no you just take the audio voltage and turn it into speaker current
to change the current of a moving speaker, you dont just change voltage the other direction
you slam it full opposite rail
until the speaker corrects
then you throttle down the voltage
to minimize overshoot

proper amp
http://www.flickr.com/photos/darkertek/2419832668/sizes/o/
thats like 100mW <.1% THD
for like $2
thats a big headphone amp!
cheap too!
haha k no rly jk
rab: http://teslaphone.com/images/xfmr1a.ed3.jpg
wtf
ac-130u: i send you one, either ourpcb or homebrew
for shipping and parts, like $5 maybe
then you can do your tube thing, and compare
btw that just needs like a 5V rail
yeah but cmoy is a hack
its like, hey lets abuse a signal amp
i bet none of those badass burr brown specs are relavent at 100mW into 16R
Posted by renesis at 07:26 | permalink | 0 comments
preamp tubes are cute, tho
tube are shit for anything except nostalgia
serious, its old tech, its been surpassed
dude
headphone amp is $2
and a bettery
serious
.01% distortion
and some big output caps
oh noz
i didnt upload headphone amp i guess\
ac-130u: i sell you one
ac-130u: a kit
by 'sell' i mean cover shipping an parts
maybe $5 or $8
fuck that thats lame
AB solid state
15:18 < AC-130U> im not looking for "warmness" as claimed by audiophools
just filter at like 15K, single pole
theres your 'warmth'

hows that working out?
oh neat
neat
you pulling vids off it cool?
kk
i think gerber editor search is fail
yeah just special cable
heheh
okay anybody have a working gerber editor?
besides me, like 3 years ago
i can become an elite cali electrician
i already finished the coursework
i just need the experience under another electrician
tubes = shit
Posted by renesis at 07:16 | permalink | 0 comments
fuck i found mutlisim 7 but not ewb
man fuck where the CAD warez at
i need ancient engineering app dump
i dont need multisim
i need gerbtool
it was packaged with version 7
hmm
yeah i guess p2p would be good for this cuz its ancient
and if theyre gonna trojan an app, they prob didnt trojan the gerber editor
i would trojan the gerber editor
WHO WOULD SUSPECT THE GERBER EDITOR!?
ok no rly i try now
Posted by renesis at 06:52 | permalink | 0 comments
man why are gerber editors so hard to steal
fuckin dumbass for losing the ewb that included gerbtool
Posted by renesis at 06:31 | permalink | 0 comments
yeah i want too
transfer is a bitch
well
actually i wanna use it for art
but for tek, fuck that
so the LED grow has bugs and tiny shrooms
prob going to abort
outdoor plants/soil is nasty, too real =(
it has tiny millpedes and worms and tiny bugs
at 5W, nothing is dying but nothing seems to be growing either (kinda expected, 14W CFL is about the same, short term, my experience)
i need to do this up with clean plants and soil
Posted by renesis at 06:08 | permalink | 0 comments
im not about to spend 2 hours trying to hand drill .012 via holes
i wouldnt do this homebrew either, my mill is like 80 lbs and struggles to do .001"
heh, backlash is totally inconsitent because of the lack of load during cnc cycles
X is .0005, Y is .003 (the more typical Y value im assuming is because its pushing the Y, the X, and the motor assemblies
neat
i got my minidin 8 cables
macegr said manhatten cables were cheap
but the package says Finest Quality Computer Products
professor: last couple and next few years is pretty much just quick prototyping practice
so the mill is nice
Posted by renesis at 06:03 | permalink | 0 comments
spend as much time doing stupid bullshit
mill = 20min to 2 hour lead time
er, 3 hour, big boards
yeah i might try photo resist
my shit never needs electrical testing, tho
yes the toner shit was like, okay now that you spent 2 hurs trying to do this right
you have to test the fuck outta it to make sure
CNC i spent a couple days making a flat clamp fixture
i spend 30sec getting the zero real close with rolling paper
and thats it
i tell the machne go and i do something else
i dont have to electrical test shit
if the tool didnt break, its 100%
i can do like maybe 10 boards easy on a $15 half round conical
single flute, 30 degrees
dart cutter, heh
you have to do like around 50% overlap too
or it wont completely cut traces, sometimes itll just push them over
we just got these 'pyramid' tip cutters
tri flute conical
if the flues bite deep enough, it should be an improvement
3x the flutes, and tougher (halk the shank m,aterial isnt removed like the half-round single flute conicals)
yeah
toner etching without a CNC is useless, imho

i think i can fit one of those and the head phone amp (even smaller) in every amp tin
http://www.flickr.com/photos/darkertek/2400415343/in/set-72157604411625937/
ninja gnd
decapus style
so guys should i write a gerber paneling script?
wait maybe eagle has one cuz like, even i can write that
shit is just parsing and add/subtract
ourpcb
i have to get shit in today
and im guessing itll wither be right on time or late
i dont care so much anymore tho
i can revise all of them for non plated use with a few vias
and just mill at home for the prototype
?
i get .015 DRC with broke ass endmills
depends on the board
and not at all, at home
toner transfer is a joke
arts and crafts project
Posted by renesis at 05:53 | permalink | 0 comments
so maybe a couple mA AC, the whole system
only ground loops are because multiple amps
yeah
bipolar is sexy like that
in one rail out the other
im doing the indicator LEDs from VCC to VEE, too
so power ground is pretty much just DC cap return
heh, im doing smps -> linear regs for all rails
ya rly
i think summer im going to try and fuck around with quartus for a few weeks
haha cool
http://www.flickr.com/photos/darkertek/2417898007/
thats the big power amp
the little power amp is a literal mirror because they just flipped the chip upside down for the big IC
like 30mil power traces and caps right on the lines
current flow is AC as fuck on one side of the caps, tho =\
Posted by renesis at 05:48 | permalink | 0 comments
haha yeah i was impressed how i fit them between the pot breakout lines underneath the filters
i was pretty sure what i wanted to do was impossible
i have another design, but power snake was a bitch to maintain
its just 7 pin breakouts
for the stereo panel pots
gnd ccw gnd com gnd cw gnd
because i have seperate power and analog grounds
except at the amps
all the caps go back to power ground
yeah
hope so
hehe the tins are going to be analog ground too
because the miniplugs are panel mount
yeah this all low power
the amps have fat traces
yeah theyre bipolar
i knew itd be a bitch fitting the bias stuff in
ha, not really
just signal bleed from filters and impedance resistors
