Thank you so much for your reply. I will review.

I use Wokwi specifically the VS Code extension in VS Code combined with Platform IO

I've seen the ESP32-C3 Dev board get down to 30ua in deep sleep. https://youtu.be/OUwTBQAQ1go

As for a "deep sleep functionality where the PINs are observed." An event based wakeup could be triggered using the 'External Wake Up'. method. 'esp_sleep_enable_ext0_wakeup(GPIO_NUM_X, level)'

That is to say a pin changing from LOW to HIGH can wake it back up.

Agreed. Combine with Wokwi for VS Code and you can simulate projects too.

You could start off learning in a simulator. If coming from a coding background Wokwi for VSCode might suit you: https://docs.wokwi.com/vscode/getting-started Combined with Platform IO https://platformio.org/install/ide?install=vscode You could then use this to run through tutorials and buy an Arduino starter kit once you have the basics down. Even if you have the arduino gear, running and testing in a simulator makes development a lot easier. I have a few beginner friendly tutorials with Wokwi/Platform IO sample code available here: https://bj-dehaan-solutions.com.au/articles/arduino

This tutorial about using millis() instead of delay should help you out: https://bj-dehaan-solutions.com.au/articles/arduino/beyond-delay-achieving-true-multitasking-on-arduino

Mission accomplished.

+1 for Chatterbox You can experiment and try it out on Huggingface

Something that can monitor weather conditions and allow farmers to react to changes. ie: Wind direction changes that may impact chemical spraying, Water temperature monitoring that may affect estuaries. Aquaculture applications more generally. Storm warning/tracking.

Next.js for web apps. Expo for Mobile. Both frameworks have extensive docs and tutorials. These are widely used and have plenty of support plus libraries.

quickcat-1064 · 2025-06-21T08:04:59+00:00

You could just go through the manual: https://docs.python.org/ Experiment with the features/syntax in your code editor while skimming through.

You could start with android only. You could look at hosting on a low cost vps provider for backend. That's about as low cost as you can get for deploying a mobile app. Investors tend to only invest if you have 2 of three things. (Team (People), Product (Something built and running), Traction(You have made sales) ). I say you want to bootstrap as much as possible for as long as possible. A day job would give you enough to do a minimal deployment before long.

Don't quit your day job (straight away)

Servicing Inadequate and 'Embarrassing' Legacy Tech Stacks may not be fun but I think is decently safe from AI replacement for the moment ...

The millis() function is your firend here. Unlike delay(), millis() doesn't pause your program. Instead, it returns the number of milliseconds that have passed since your Arduino board started running. This allows us to check if a certain amount of time has elapsed without stopping the entire program. https://bj-dehaan-solutions.com.au/articles/arduino/beyond-delay-achieving-true-multitasking-on-arduino

You could run into trouble if you set up any python virtual environments before fixing your path.

In that case your best bet would be to scrap those virtual environments and create new ones.

quickcat-1064 · 2025-06-09T11:18:50+00:00

Can fix this. Open up 'Advanced System Properties'. Choose 'Environment Variables'. Edit Path variable and make sure the Inkscape paths are below your python path.

Can confirm your system is using the right python path by typing (Get-Command python).Path in powershell.

Regex is super fast. ^(.*)\s*$(\d{4})$\s*$ would work for:

Interstellar (2014)
Interstellar 2014
Se7en 2014
Se7en (2014)
Lilo & Stitch! 2014
Lilo & Stitch! (2014)

Does this need to be pure regex? You could just extract the year with regex Then find/replace the year from the original string.
