i found an amp but its $4 =\
use a voltage regulator
3pin linear is easiest
yeah what _m_ said

Posted by renesis at 23:46 | permalink | 0 comments


like 50nV/sqrt(Hz)
ne5532 is like 5-8nV depending on test condition
bye
fun
yay
haha yeah i gotta make money first
ok so i guess i run ttmustangs board
fix the wtf via on dx board and run that
write letter of rec for geeker cute english teacher
and do timecops new expresscard failboard
okay well i guess a day of rest is almost like a week
oh i guess tc failboard pays for heaphone amp kits
okay i need 4V swing
so yeah either a normal amp on the 9V (close, but maybe) or a rail to rail

Posted by renesis at 23:38 | permalink | 0 comments


low noise rail to rail amps?
signal power, rly low noise
no just audio but the headphone amp is nice no reason to fuck it up
i dont really want to run a buffer amp at unregged 9V
and id still prob only get like 3 or 4v max swing
the headphone amp is 5v
naw just one, id use switchers first and i really dont want too
so rail to rail of a 5V reg would be neat...
i think the ones i chose for shift vu controller were just cheap, not good
mostly seems to be video signal amps

23:08 < renesis> did you see superbad?
go see it that shit is actually pretty funny
more than one person said the fat kid reminded them of me in high school =\ =\ =\ (i was loud, back then)

i got a few standoff assortments from goldmine-elec.com

Posted by renesis at 23:14 | permalink | 0 comments


oh the negative input
see i am tired, and yeah that is weird
the RC pullups i did for the 5+5W amps worked good
for standby and mute, no turnon pop
i killed the 10+10W amp, reverse its rails
ha, eeepc audio out survives (i wonder if i just lifted the whole laptops ground)
hahaha
did you see superbad?

Posted by renesis at 15:09 | permalink | 0 comments


again =(
heheh
this is neat
i might be able to just throw the tone circuit onto the headphone chipamp
its built into the feedback/input network of an inverting amp
nice
the chipamps are inverting input with internal bias on the non inverting amp input
so like, i can just AC couple the circuit and throw it onto the headphone amp
i should try it i have all the parts
then i just need a buffer amp for the input bandpass/gain section
yeah i bought those
oh
yeah they have those too
mine is an external gain amp, but the datasheet has fixed gain versions
like 0db, +3 and +6 i think, but they arent making them yet, proposed =)
well, its kinda cool for really tiny shit
but yeah its not like 0402 resistors couldnt handle it

yarly
im not doing timecops board either he has to wait too
hell i prob shouldnt even be playing with digikey im prob gonna break it for everyone

Posted by renesis at 14:57 | permalink | 0 comments


rail to rail quad amp, headphone amp, linear 5v reg
and some passives and connectors and switches and pots
all in an easy to mount altoids compatible footprint
death of cmoy amp, ph33r

i just gotta copy from ltspice mostly
then ima crash
again but for like a continuous stretch of time
timecop_: ask lordpil.com repeat user for donation
o
i guess i just did
yeah theres alot of free knowledge there
alot more, um, not so useful stuff i guess
cuz spam
for hits
you prob tripped a random sense algorithm
that means nothing to me without graphs or tabled values or something

Posted by renesis at 14:42 | permalink | 0 comments


haha
meh
dx^: i do you board thing tomorrow because i have to move one via and some parts
and im too tired to think hard
like, can run the cnc half asleep but i prob manage to delete half the work and save it in half a click
yes exactly
id prob be asleep but theres like all sort of boxes and bins and shit on my bed
i think ima do a digikey part list for curiously ultramega headphone amp

like, oh my bad i didnt know you could read minds
the convos get very circular
i dont like fluffy double ply
it like crumbles wtf
and actually baby wipes are #1
man we spoil baby butts
like, special engineer stuff for them, but we just use random paper on rolls
actually i would have went nuts if it wasnt for another girl
but that girl is like, thinky rational, exgf is like, feely emotional

my best girlbuddy wouldnt look at me for like 2 days
srs she lik talked to me with her back turned and her hands over her face repeating 'nooooooo'
and then school police guy was like 'ok we all know you liked your big hair, so like you got your green mil backpack, hiking boots, shaved head... are you trying to make a statement? is this some sort of like nazi thing?'

21:25 < AC-130U> er... what are the ways to secure workpiece to milling table?
setup is 95% of machining =)
answer: whatever works for the part
most production shit, you would machine a specific fixture if you dont already have a setup that works

your board is nuts
i forgot
no errors at 8mil drc
oh, yeah this an 8mil board not a 10mil board
124 fucks yous from 10mil drc
traces are like .015 min i think
.018 i guess
i can go deep with the cutter no issue, then
.005 tip, 30 degree 3-face pyramids

Posted by renesis at 12:25 | permalink | 0 comments


you dont need 30K on big shit
ha ball nose
big radiuses pwn
yeah cnc will cut so clean you can see all the toolmarks almost any size of cut
so you have to finish anyway
yeah
hells yeh
you can do most shit like that
they made complex parts on standard manual mills
they didnt do it raster style
they did it with angle plates and rotary tables and shit
lots of trig
heheh
the ball nose shit is just top down too
5axis can get under overhangs
damn dx

Posted by renesis at 12:20 | permalink | 0 comments


some of those are .007 DRC (meant for chinapcb, but they spent 4 days being retards so had to try to do at home)
yeah some of that shit is awful
i just eyeballed after flipping with the pyramid mill
i use grease
i think mobilith
mobile lithium grease or some shit, whatever was cheap
tinning and mask would be neat
.015 shit came out awesome
whats a hurco?
yeah but what
nc mill?
meh, that might just piss me off
the haas controllers were neat, i was getting them to do shit even the instructor didnt know about
i think .01
what do they do

i dont think your boards will be a problem
i didnt on most of them
i tried to do a crossover and mostly just got pissed off
you can see where i got all lazy aligning after flips
def wasnt supposed to be homebrew
neat to know i can do it, tho
if twingy figures out a good via punch thing, maybe stuff like that not such a big deal
not really, most of the boards are useable
and that shit was awesome, CNC ran for like 4 days straight, no problems at all
curiously strong boards

timecop_: okay so i assume im doing that with mask layers or something?
yeah
so its open, solderable

like, wtf 10K, what the FUCK does that have to do with 8-32R impedance headphones?
none of the specs on the amps mean anything when youre driving headphones with them
okay i think im going to integrate curiously strong preamp and curiously strong headphone amp into death of cmoy headphone amp (okay but im gonna still call it curiously strong headphone amp, shh)

Posted by renesis at 02:37 | permalink | 0 comments


bye
see this is my prob with cmoy amp retardation

15V bipolar rails, 10K load, ambient temp 77F
its prob way hotter than 77F very often when worn in your pocket, against your hip, with the amp overdriven

Posted by renesis at 02:32 | permalink | 0 comments


not really, its more for personal 0 day prototype
ill do it for anyone in here, pretty much
not really, because pcb fab is cheap
and machining them is kinda labor intensive when you have to manually tool change and flip
its not as bad a toner transfer etching tho
man that was like arts and crafts from hell with the high resolution shit
like, it might take longer, but its less work for me, drill changes go quick, takes a few minutes to do all drills
and i set the trace cutter Z and just let the shit run, i can do other shit
oh it depends on alot of things
also i dont have alot of bigger drill sizes
so i do those with endmills
also pcb-gcode sucks
so i have to manual edit the drill files and find/replace all feed instances because it ignores Z feed rate parameter
like, its really alot of very good work
but that shit totally pissed me off why the fuck are you not gonna use the Z feed rate option value to do Z feeds

Posted by renesis at 02:25 | permalink | 0 comments


yeah, i might get a china <.0005 tolerance set
i should get an inspection plate and square plate and cheapo height micrometers
fuck i need to call enco and ask how much shipping is on their little ones
yeah i get those
hmm
well, no money now, id be negative money if my mom wasnt awesome
im gonna cut my hair and get a job, ph33r
i cant deal with financial aid dropping out on me while im at a uni
shit is 20x what i pay for school now
like, im $7K in subsidized loans in debt, but i have mad shit to show for it
thats prob like, one semester at a uni

Posted by renesis at 02:20 | permalink | 0 comments


they were $30, red dial on black face w/ white marks, theyre pretty okay
we use lots of china shit from enco at school
and then we have some nicer stuff, the china shit usually isnt off anything meaningful
bid or buy?
how much ching?
thats not bad for really good inspection shit
i know someone paid that much for mit diamater micrometers just for measuring drills
yeah but im not really doing mad inspection shit
taig is like .002 unless im super careful, so my crappy stuff is good enough
im going to take it apart and clean it
yeah
i should get a china set
haha .001
dont breathe to hard =(

Posted by renesis at 02:10 | permalink | 0 comments


oooo
mitutoyo are nice
i have shit calipers that wont die, i dont want to buy new ones until i can afford mitutoyo calipers
very nice japanese inspection tools
yeh
no
but i learn from a bunch of old manual and cnc machinists
who swear theyeve seen all sorts of digitals uncalibrate just by moving them to quick or using them a bunch
dial calipers works, you can adjust the bezel for offsetting measurements, and the mechanism, is practicallt fullproof
every ones in awhile, the gear will skip because the face got pushed out or something (shit happens)
adjust bezel, works fine (tho like at 90d off north for 0 or something heh)
dial gages are super easy to read
like you dont even have to read them one your kinda fixed on one measurement
you can just glance and see if the needle is around where its supposed to be, depending on tolerance
ok
yeah i <3 enco

Cross-dressing prostitutes lied when they accused AC Milan striker Ronaldo of using drugs and having sex with them during a motel encounter last week, police said Tuesday.
heh
The prostitutes told police they lied because Ronaldo did not want to pay them after finding out they were men, police inspector Carlos Augusto Nogueira said.
see, alcohol is bad
you know he was mad drunk
He said he offered to pay the prostitutes even after finding out they were men, but one of them demanded more than offered.
okay now is just becoming silly i wish there was like hidden cam vid
