That is the problem I can't find anything on the board. Thats way I think it was the esp.
Me No Dev
@me-no-dev
the esp is well shielded :) i doubt it will let any smoke
any chance you take a high res picture and post it here?
FWeinb
@FWeinb
Sure, just a sec.
Me No Dev
@me-no-dev
there is one small diode on the board but I can not tell how it's connected by just looking at the image
if it's used to pass the power and too high of a current have passed through
it could have gone dead
Martin Ayotte
@martinayotte
I don't see any diode there, at least from the picture. It could be on the bottom side. (I hope your PC USB isn't damage too)
FWeinb
@FWeinb
USB is fine.
Just stupid to not change the multimeter...
There is nothing on the bottom.
Me No Dev
@me-no-dev
@martinayotte right next to the LED (on the left)
Martin Ayotte
@martinayotte
Maybe the VReg itself ... (For example, on the Wemos, there is no diode, so it would be the RT9013 that will come into smoke)
Me No Dev
@me-no-dev
but he shorted the incomming power
not the 3.3 and GND
so the LDO should be fine
Martin Ayotte
@martinayotte
Ah ! ... so, you mean the small black near the crystal ? could be it
I've done the quite the same mistake with some STM32 MapleMini, I've purchased such diodes 50 pieces for $2
In mean time getting spare part, simple wire could be placed there, as long as you don't do same mistake, for the health of you PC USB ;-)
FWeinb
@FWeinb
Yeah. I will not be a little bit more carefull.

@Makuna
@mozgy yeah, I wish we could tag a rating system on that list. I wish Arduino would add a rating system to the Library and Board Manager.
tzapu
@tzapu
or at least the github stars each package has, already there as information ..

@Makuna
@FWeinb @me-no-dev Everytime I tried hot air, I ruined the module, as pieces under that shield would "slide" on the slightest movement. I wish you good luck as I didn't have it and figured it was just cheaper to replace it.
Me No Dev
@me-no-dev
@Makuna I have done it :) patience helps
decapped many modules as well without any damage to the internals
FWeinb
@FWeinb
The good thing is that these esps are as cheap as it gets so no worry. Thanks for the help!
Martin Ayotte
@martinayotte
@FWeinb , did you tried to replace temporarily the diode with a simple wire ?
Keith Andrew Hill
@vic10us
Looks like there is a little damage on the left J3Y
FWeinb
@FWeinb
@martinayotte that isn't helping. @vic10us that was just some dirt...
Mario Mikočević
@mozgy
@Makuna very good idea
Martin Ayotte
@martinayotte
@FWeinb did you check if the USB cable is still good ? (because it can have been damaged by the short)
FWeinb
@FWeinb
Did test with another cable.

So pubsubclient lib anyone worked with that. I tried to mash the mqtt example with the gesture sensor example but im not sure how to do the mqtt publish thing
Stavros Korokithakis
@skorokithakis
@marksev1 i have some code
this is platformio's 89 lib
Stavros Korokithakis
@skorokithakis
does anyone have a handy stub or some code that shows how to write a library?
i want to have a main file and then some hooks that will be called, on a separate file

@geman220
Can anyone point me in the direction of a good tutorial to start learning how to program and use an ESP8266. I'm completely new, looking to have the ESP rotate a small servo to automate my blinds.
Stavros Korokithakis
@skorokithakis
@geman220 i need to write one, really
@geman220 how comfortable are you with the command line?
geman220
@geman220
I'm a decent programmer
Not by profession but I can get around
I bought 10x of these http://www.aliexpress.com/store/product/D1-mini-Mini-NodeMcu-4M-bytes-Lua-WIFI-Internet-of-Things-development-board-based-ESP8266/1331105_32529101036.html . I am going to use it with a LiOn solar battery Output:DC 5V/1A; 5V2.1A so I will need a Voltage regulator before I plug the USB into the micro-USB slot to power it correct?
Aditya Tannu
@AdySan
Nah if it's 5v already should be good to power the nodemcu board
geman220
@geman220
Ah okay
Aditya Tannu
@AdySan
There's an onboard lm1117 to bring it down to 3.3V for the esp
geman220
@geman220
Can you tell me how difficult what I'm trying to accomplish is? I want to hook up 10 of these to 1 servo each and a LiOn solar battery. I need to the ESP's to subscribe to an MQTT topic and rotate the servos so they can open/close my blinds. I don't mean pull the blinds up, just rotate the wheel that opens/closes the slats of the blinds.
On a scale of 1 - 10 what am I getting myself into
