So the rotation should be in reverse? It pushes down to the scale right?

You can use LORA WAN module

So I guess this wouldn't solve your 5km challenge @wafa_athmani, but made me think of the RONJA (Reasonable Optical Near Joint Access) device/communication method https://en.wikipedia.org/wiki/RONJA

Basically it shoots a laser from one device to the other for a communication range of just under a mile at 10 Mbit/s. So how I would imaging a tightbeam comms device would work from The Expanse, though you'd have to consider a LOT more factors with that kind of distance/speed. But who knows, maybe it could spark another idea?

RONJA

RONJA (Reasonable Optical Near Joint Access) is a free-space optical communication system originating in the Czech Republic, developed by Karel Kulhavý of Twibright Labs and released in 2001. It transmits data wirelessly using beams of light. Ronja can be used to create a 10 Mbit/s full of duplex Ethernet point-to-point link. It has been estimat...

So guys I'm using ZeroMQ for inter-process communication in my application. I have two separate processes running on the same machine, each with their own ZeroMQ endpoint. When I try to send messages from one process to the other, I'm noticing that some messages are not being received by the receiving process. Both endpoints are bound to the same protocol, address, and port. I've checked for common issues like incorrect socket types and binding conflicts, but I'm still experiencing the problem intermittently. What are some potential causes for messages not being delivered, and what steps can I take to effectively diagnose and resolve this issue? Please any assistance?

wafa_athOP•3/25/24, 5:49 PM

Actually this is very interesting method.. i will take a look on it , thank you so much

Joseph Ogbonna•3/25/24, 6:17 PM

The issue of messages not being delivered in ZeroMQ could be caused by various factors such as network congestion, incorrect socket configurations, or a mismatch in socket types between the sender and receiver. To troubleshoot, ensure that both endpoints are using compatible socket types (e.g., PUB/SUB, REQ/REP), check for any network issues or firewall settings blocking communication, and verify that both processes are actively listening for incoming messages. Additionally, logging message send and receive events can help identify any patterns or inconsistencies in message delivery.

Hi guys,
I arrived in China today. Got through the border control with the first batch of Beetle Boards. Wasn't straightforward though. Look:

kristof-at-embeetle•3/25/24, 10:54 PM

Hahahaha

kristof-at-embeetle•3/25/24, 10:54 PM

Border control asked me to open one

They look like something.. Lol

kristof-at-embeetle•3/25/24, 10:55 PM

kristof-at-embeetle•3/25/24, 10:56 PM

This is what they look like if not wrapped up in plastic foil.

kristof-at-embeetle•3/25/24, 10:56 PM

But yeah ... wrapped up in plastic foil, the Beetle Boards look suspicious

Kkristof-at-embeetle This is what they look like if not wrapped up in plastic foil.

aymen ammari•3/25/24, 10:57 PM

Now they look well organised and well manufactured

kristof-at-embeetle•3/25/24, 10:57 PM

Thanks @aymen ammari

kristof-at-embeetle•3/25/24, 10:57 PM

Talk to Brandon if you want one

kristof-at-embeetle•3/25/24, 10:58 PM

He's doing the distribution in the DevHeads community for us

aymen ammari•3/25/24, 10:58 PM

Yeah I want

kristof-at-embeetle•3/25/24, 10:58 PM

aymen ammari•3/25/24, 10:58 PM

Ok ok

kristof-at-embeetle•3/25/24, 10:58 PM

Great

kristof-at-embeetle•3/25/24, 10:58 PM

Software to program this board is of course Embeetle IDE

aymen ammari•3/25/24, 10:59 PM

Can you send the link to download it

kristof-at-embeetle•3/25/24, 10:59 PM

Sure:

Do you have any example code implement event-driven programming in esp32-s3 or another platform for refences purposes ?

So you ordered these micros from china to put them into individually wrapped foils and take them back into china lol

kristof-at-embeetle•3/26/24, 2:43 AM

Hahaha

kristof-at-embeetle•3/26/24, 2:43 AM

Yeah

kristof-at-embeetle•3/26/24, 2:44 AM

You could say that

kristof-at-embeetle•3/26/24, 2:44 AM

These Beetle Boards made quite a trip

Aaymen ammari Yeah I want

techielew•3/26/24, 2:44 AM

You have to send a selfie here with you and the downloaded embeetle ide

kristof-at-embeetle•3/26/24, 2:44 AM

Soon some of them will go with you to US

techielew•3/26/24, 2:44 AM

will those be in foils too?

Morning everyone! I have a small question I want to operate 2 strips like this one with an Arduino Mega, the LEDs look a bit dim when I turn them on, like a drop in power! Should I power them with another 5 volts or should I add resistors? If resistors, how many ohms? Thank u in advance.

wafa_athOP•3/26/24, 10:47 AM

Adding resistors won't help, they'd just make the LEDs dimmer. a relay can be used to control power to the LED strips, maybe you need a additional power supply The issue might also lie with the LED strips themselves...
