@comino
free is limited - even pro is cheap compared to altium ;)
Stavros Korokithakis
@skorokithakis
hmm, i was going to start with eagle, but i saw this thread https://news.ycombinator.com/item?id=10676514
how much is altium?
Sven Eliasson
@comino
wow - looks like there is a good progress on kiCad
I will give it a try
Stavros Korokithakis
@skorokithakis
@comino the commenters there seem to like it a lot
Sven Eliasson
@comino
too much if your employer doesnt buy it for you ;) or you doo.. you know.. harhar
Stavros Korokithakis
@skorokithakis
i've used both, but i've never designed a pcb, so i couldn't say
@comino haha, yep
Chris Elsworth
@celsworth
anyone know what the max pwm frequency an esp can do?
Sven Eliasson
@comino
oh that was also on my research list ^^
Stavros Korokithakis
@skorokithakis
@celsworth 2 usec seemed fine
Chris Elsworth
@celsworth
that'd be.. 500kHz? I guess that will do :)
Stavros Korokithakis
@skorokithakis
yeah
Chris Elsworth
@celsworth
going to run it through a lowpass filter to make a DC voltage, 500k will be loads
Stavros Korokithakis
@skorokithakis
i used bit-banging to make the carrier wave for that remote control
if i wanted 26 usec highs, i had to delay for 24
so i'm guessing you can get 500 khz
actually sorry
1 usec
so probably 1 mhz
try it out, though, can't be too hard to write a for loop :P

@beikeland
main downside to Eagle is you only get one sheet for the schematic. Board size and layers limitations hasn't been an issue yet. (unless you try to do panels, but there are other tools to do so). But it does sound like its time to look at KiCad again
Chris Elsworth
@celsworth
time for scope testing I guess
Stavros Korokithakis
@skorokithakis
@celsworth do you have a logic analyzer?
Chris Elsworth
@celsworth
only a cheap ripoff.. £15 from aliexpress thing
but yes
Stavros Korokithakis
@skorokithakis
hah, 15 quid? i got mine for $7 :P
Chris Elsworth
@celsworth
it was still a lot cheaper than a Saelae ;)
Stavros Korokithakis
@skorokithakis
but yeah, i was going to offer to check out the frequency if you didn't have one
i agree
i kinda feel bad though, their logic analyzer software is so good that i want to support them
maybe my next analyzer will be a saleae
Chris Elsworth
@celsworth
likewise, but they are very expensive :/
Stavros Korokithakis
@skorokithakis
eh, it's less than $100 i think
oh, $109
not prohibitively expensive, but yeah, it's not $7
Chris Elsworth
@celsworth
well, the 4 isn't.. very good :/
Stavros Korokithakis
@skorokithakis
oh? why not?
Chris Elsworth
@celsworth
it looks quite limited in speed, very low sample rates?
the 8 is almost 10 times faster
Stavros Korokithakis
@skorokithakis
hm that's true
i'm a novice, so for what i do i only need kilosamples/sec
Chris Elsworth
@celsworth
and also you get a lot more analog ports on the 8, only 1 on the 4
Stavros Korokithakis
@skorokithakis
i think my cheapo chinese one can do 25 MS/s
yeah :/
Chris Elsworth
@celsworth
even that 25M/s is faster than the Logic 4 :(
Stavros Korokithakis
@skorokithakis
yeah exactly
so you'd be paying 12 times more for a downgrade
Chris Elsworth
@celsworth
yep, kinda silly
