S@Elomunait Welcome! Can you let us know a bit about your technical background, what brings you to DevHeads, and what you're looking to learn/contribute?!
S@Rémi Welcome! Can you let us know a bit about your technical background, what brings you to DevHeads, and what you're looking to learn/contribute?!
THey @everyone! Come join me, @Petr Dvořák and the other DevHeads in a few minutes as we look at Ohm's Law in this week's Office Hours Meetup! https://discord.gg/97CdaKsB?event=1221106272028590170
YKicad or easy eda
AKicad is good but easy eda is better because it's online, you won't struggle with footprints
YEasyeda is available online and software and it is big community
AOh, I didn't know that
YHere the download link https://easyeda.com/page/download

RHey there is a channel for this ?
NFeel free to talk about yourself, your technical background, or any project you're working on here
ROkay thanks.
I'm Rémi I come from France
Currently I'm working on trains (the software part) and in my free time I'm working on a slam robotics project

RI'm working mainly with c/c++
RBefore all that I was web developer
RFor about 3 years
NWelcome @Rémi Happy to have you as a DevHead!
RThanks
RI'm happy to be here
RIt's the first embedded systems community I found on discord
RIt's nice to have somewhere to talk about all of this
NYou are in the right place, if you have any questions, do not hesitate to ask them here or in the forums:
NRYeah I saw it thanks
AHi everyone, I'm searching for a cnc cut design for my flight frame, does anyone have a ready design? Thanks in advance
BI bought an F450, and I have a website, but I'm not sure if it would be helpful to you
BS@Ash13 Welcome! Can you let us know a bit about your technical background, what brings you to DevHeads, and what you're looking to learn/contribute?!
AHi everyone, I am Abhi. I work on battery management systems (BMS) on algorithm (embedded C) , testing automation and data (python) making the BMS more intelligent to detect and diagnose faults faster. Looking for collaborations with fellow engineers!
Bhey , how can we help?
MGood day guys ! Please does anyone have any idea on scheduling algorithms on RTOS for automotive control systems ?

TBthank you , I will try it
TSlam for what type of robots? @Yash Naidu and you might get along
T@Umesh Lokhande dyk?
THi @skarif what are you working on?
SHiii @techielew i got into Embedded Ai and working as a research Engineer. Seeking to explore deeper into hard core Embedded systems. If anyof you can suggest a clear roadmap it will be highly appreciated. Thanks 
UUsually, MQTT protocol allows the payload size of up to 256 MB. But always recommended to check with the broker documentation to ensure if there is any limit from mqtt broker s/w side. I don't think the size has to do with MCU either ESP32 or any other
YPublishing an important size of data we'll block the cpu or just pass data to the tcp/ip stack and initiate tye transfer and do something else ?
UI'd prefer asynchronous handling of data using buffer and then let the CPU handle other tasks. In this case, data transfer will be hapenning in the background so the CPU is free to complete other tasks
T@Middleware & OS any micropython users in server? We’re discussing C, Rust, Python/micropython on next week’s Office Hours and would love the additional perspective? I know @abhishek awasthi is a Python user, @barafael is a rust lover, and everyone better know some C/C++ 
(hopefully @kmulier will be able to join and lend some perspectives).
If you’d like to address any other languages lmk but really curious if there’s a micropython power user in the house!

WHello @techielew i did use micro python several times to program ESP32 and STM
AThank you Ben but I'm searching for one that can be cut by cnc, cuz 3d printing is not available, do you have any other ideas?
TThat’s great do you want to join OH on Friday and lend some of your experience to the discussion?
CHi! Has anyone already used the MQTT protocol with an ESP32 for external access to the local network? Is there any documentation available to set up such a system or a tutorial?
