Re: Date/Time management

Often there is a confusion because python and linux have a different weekday logc. Python having monday as 0 while linux has Sunday as 0.

Re: Control exact polling rates using uasyncio

Or if timing is that important, use an interrupt approach with timers to read the uart every e.g. 50ms into a preallocated buffer.
Question is of course, why you would need to do that as the uart has a buffer.

Re: Wemos W600-Pico

The devices you mention are all internet connected devices and I agree that you have to be very careful about those as they are more likely to get attacked/hacked. If my device is only sending/receiving messages locally through mqtt the attack surface is a lot smaller. But of course to be more secur...

Re: Wemos W600-Pico

oh it sure can and maybe some of my friends with my wifi password could be a risk too but I'm not that paranoid at the moment :D
What should an attacker do with all my smarthome nodes? Read all my temperatures? Ring the doorbell until I die :lol: It really depends on what you are connecting.

Re: January 2020 Melbourne MicroPython Meetup

The W600-PICO by Wemos is listed as "no longer available" but if you browse the same link on mobile the message is the slightly clearer "out of stock". It seems they've been popular! I bought a couple and can spare one if you're really keen? :) Oh I didn't try it on mobile, thanks! Guess I'll just ...

Re: January 2020 Melbourne MicroPython Meetup

The Wemos W600-PICO looked promising as an alternative to esp8266 but it isn't sold on Aliexpress anymore? Can't find it anywhere :/

Re: How to run an mqtt-repl?

If you send 100 1kb messages using mqtt_as they will arrive in order and reliable with qos==1. You don't send them in parallel and you are using TCP. Qos1 already has ACK in it and retransmission will occur if the package doesn't get an ACK --> you can send 100 1kb messages and they will safely arri...

Re: Connecting a Canon DSLR camera to Computer wirelessly

I wouldn't make it that complicated and rely on existing software for USB over IP like: https://www.virtualhere.com/usb_server_software You can just attach the camera to a Raspberry Pi and use it on your PC like it was locally connected. I used such a system (but not with a camera) years ago with a ...
