@d-anders
most of my esp8266/arduino projects are small anyway, so most important is for everything to just work, including libraries etc

@skorokithakis
damn, these 3V3 regulators just don't want to stay cool with 9v input
Stavros Korokithakis
@skorokithakis
i have to ground gpio0 to flash, right?
Stavros Korokithakis
@skorokithakis
@martinayotte do you know offhand if you can PWM these H-bridges?
Michael Miller
@Makuna
@skorokithakis are they linear voltage regulators? That big difference for linears causes lots of heat.
Stavros Korokithakis
@skorokithakis
@Makuna yeah, they are, but i didn't expect them to get that hot
i replaced it with a regulator board and it's fine now
i was just surprised
Michael Miller
@Makuna
they are inefficient , use a switching regulator ;-)
Stavros Korokithakis
@skorokithakis
hmm, like which one?
Michael Miller
@Makuna
those are switching (buck converters) and not linears. Ok, that is strange that they are getting that hot unless you are drawing more power than they are rated for. If you are only running the esp8266, they seem fine (wording seems weird, but I suspect they are peak 3A, continues 1.8A, but probably over stated at that.
Stavros Korokithakis
@skorokithakis
no, those are fine, my linears were getting hot
Stavros Korokithakis
@skorokithakis
i'm only running the esp, yeah
i'm running some motors directly from the psu, but that's irrelevant
goddamnit
smoke
what could i have burnt?
Stavros Korokithakis
@skorokithakis
nothing, it seems
the ESP keeps disconnecting, too
could it be interference from the motors?

What's the best stepper for use in a small CNC or 3D printer on a budget?
Is a NEMA17 big enough?
Michael Miller
@Makuna
@skorokithakis what sort of motors? If its a standard brushed motor, why yes, they put out a lot of noise. You can put caps right at the motor that helps this (look up RC Motor Filtering Caps).

@tzapu
@ivankravets , i cought you again :P
(1h later, oops)
the platform ide, can t coexist with another atom configured for web development i guess, is that correct?
it s one atom loaded with all plugins for everything...
tzapu
@tzapu
also, when using arduino ide compatibility, and library manager i get this error about not finding a lib, https://www.dropbox.com/s/c49j7naos0eqlrf/Screenshot%202016-03-25%2010.41.00.png?dl=0
although it compiles fine it seems...
ehich goes away if i add #include <Arduino.h>
but is that the right thing to do for an esp8266 project?
Stavros Korokithakis
@skorokithakis
@Makuna hmm, but then I won't be able to PWM them, right?
Stavros Korokithakis
@skorokithakis
alright something in this build is smoking a lot
is it the H-bridge? how much current does a motor draw?
Stavros Korokithakis
@skorokithakis
aw, three amps :(
Martin Ayotte
@martinayotte
@skorokithakis , you means that your motor is taking 3A ?
Stavros Korokithakis
@skorokithakis
Yes :-(
Martin Ayotte
@martinayotte
Ouch ! even a L298N module will be too border line. Is this motor so big ?
Baruch Even
@baruch
I'm using the http upgrade mechanism and it works nicely but there is no info on progress or hooks to add them, would it be ok if I created a patch to add some hooks in there? I want serial prints but I would also be interested in my mqtt server updated with the status too for an over-the-network monitoring of sorts
Stavros Korokithakis
@skorokithakis
@martinayotte yes, it's an RC car so it has a lot of torque
i ordered an L298N, it says 3A peak, so hopefully it will work
it does 800 mA with no resistance, so it was working fine when the motor was free-spinning, but if it runs against a wall it surges to 3A
Ivan Grokhotkov
@igrr
@baruch it's not recommended to run other TCP connections while OTA is in progress
this may affect the OTA
Baruch Even
@baruch
I'm not looking for continuous updates, just a "upgrade checking", "upgrade not needed", "upgrade in progress" status
Stavros Korokithakis
@skorokithakis
can't you do that already?
Ivan Grokhotkov
@igrr
Okay, that makes sense
Baruch Even
@baruch
I saw the code already disables all TCP connections other than its own
