there are many rules and constraints, which software do you use for pcb design?

Oonky there are many rules and constraints, which software do you use for pcb design?

aymen ammari•3/2/24, 7:55 AM

Kicad

aymen ammari•3/2/24, 7:56 AM

I mean is there a rules I should follow when I want my pcb to be commercial?

onkyOP•3/2/24, 7:58 AM

One thing you can do is, check the website of pcb fabricator, like JLCpcb, pcbway etc. they provides their capabilities, so you can set this on ki cad.

onkyOP•3/2/24, 7:58 AM

open board setup and go to Design Rules

onkyOP•3/2/24, 8:04 AM

In addition, make sure that physical stackup also matches to the fabricator capabilities.

Hi @Jd3n Here's step-by-step video about how to use MQTT protocol to control and monitor devices connected to ESP8266 https://youtu.be/c1st5cVRRzo. Once you understand how publish and subscribe works then you'll be ready to use MQTT Palette in Node-RED which will help you build a UI to control ESP8266.

MQTT Protocol with NodeMCU ESP8266 Tutorial

Let’s learn how to use MQTT Protocol with NodeMCU ESP8266. We’ll create example project on how to control LED and monitor sensor data using publish and subscribe mechanism of MQTT Protocol. We’ll use MQTT server Mosquito. MQTTLens as a web client. And MyMQTT Mobile App as a MQTT Client.

I would suggest approach this problem in a 2-step solution. 1st step is to learn MQTT with ESP8266. 2nd step is to learn Node-RED to integrate ESP8266 using MQTT protocol I'll soon cover this topic in our upcoming Learning Hours (LH). Stay tuned for announcements

Umesh Lokhande•3/3/24, 10:32 AM

Hi @Shrushti have you tried running the beast server using beast start --port 8000beast start --port 8000 command? If you have, and it still fails, you should contact the author of the netbeast Node-RED they provide their contact information in the node's readme file

Umesh Lokhande•3/3/24, 10:46 AM

It seems to me there may be missing dependencies during the installation Netbeast node palette or an API error in the node palette's NodeJSNodeJS code. The Author of the Netbeast node can only tell us more about this. But I don't think this issue is from Node-RED

Shrushti•3/3/24, 10:48 AM

Oh ok thanks

techielew•3/3/24, 11:03 AM

@momo301199 without more context, I'd recommend joining our weekly Office Hours meetup (https://discord.com/events/1130679493799977062/1210639837787328642/1215675393638400000) and in a couple weeks attending Learning Hour (https://discord.gg/MTDjdGyq?event=1212289328340795392) so we can get to know you better and give you a chance to get started in a direction.

Shrushti•3/3/24, 12:03 PM

Is there a alternative to netbeast? @Umesh Lokhande

SShrushti Is there a alternative to netbeast? @Umesh Lokhande

Yes, openHAB is good alternative as its a open-source and platfrom agnostic. Check out https://www.openhab.org/

techielew•3/3/24, 9:59 PM

Hmmm, tough one. @abhishek awasthi?

There was another question recently about distributed systems architectures. There's a company who doesn't do Linux per se but has a companion RTOS to Windows/Linux hosts that is capable of managing distributed applications. I know this isn't what you're looking for but perhaps some of the documentation on page 4 here can give you a conceptual idea: https://tenasys.com/wp-content/uploads/2023/09/TenAsys.DS_.RTOS_.v3.92123.pdf

techielew•3/3/24, 10:01 PM

This RTOS uses networked global objects to communicate between processes (IPC), including distributed ones

Lora stuff is pretty standard once you use the right frequency

What are #LVDS Low voltage Differential signals and use cases ?

Yyoucef_ali What are #LVDS Low voltage Differential signals and use cases ?

aymen ammari•3/4/24, 11:12 AM

Low Voltage Differential Signaling (LVDS) is a method for transmitting digital data at high speeds over twisted-pair copper cables. LVDS uses differential signaling, meaning it sends the same signal over two wires with opposite polarities. This helps reduce noise and increase the immunity to electromagnetic interference.

LVDS is commonly used in various applications, including:

1. High-Speed Data Transmission: LVDS is widely used in applications requiring high-speed data transfer, such as displays, monitors, and high-speed serial communication links.
2. Display Interfaces: LVDS is often used in flat-panel displays, such as LCD and OLED screens, to transmit video data from the graphics controller to the display panel.
3. Automotive Applications: LVDS is employed in automotive systems for transmitting video signals between components such as cameras, displays, and infotainment systems.
4. Industrial Applications: LVDS is utilized in industrial automation systems, where high-speed, reliable data transmission is essential for control and monitoring purposes.
5. Networking Equipment: LVDS can be found in networking equipment, such as routers and switches, for transmitting data between different network components.

Overall, LVDS offers high-speed, low-power, and reliable data transmission, making it suitable for a wide range of applications where high-speed digital communication is required.
