Some useful and / or yummy code to remind my brain what I already forgot (again) – and for your amusement.
It is prime day and you are wondering which kettlebells to buy? What are the possible weight combinations of all different weights including using between one and all of them with a dip belt? Yeah that’s really the motivation of how this started 🙂 What became of if was a method taking multiple int values,…
A small script to scan the neighbouring Wifis with your microcontroller. You get the following information about them: Kept the code as simple and small as possible. Available functions in network package could vary depending on used microcontroller type and micropython version / implementation. Resource links:
I currently had the problem of handling updates with partial settings of RGB lights through MQTT and HomeAssistant. As The setting has to be complete at all times in the running system, so my first solution were multiple if else clauses and changed flags. It works, but it is ugly and over-complicated. I didn’t use…
A milltion times already on the internet and sorting methods already integrated in the language – so why?Because written things stay better in the brain and I like to understand things from the ground. ArjanCodes (I love your content!) recently posted a video about recursive functions and used a similar code. I won’t have written…
For a container class with a dictionary with config values (among other members) I wanted easy reading access as if it was a dict itself. For that you only have to implement the __getitem__ method. You can extend the provided dict functionality for your class if needed like the following: All but the update method…
As most of the time – there are multiple valid ways of doing it. Keeping the order I prefer easy and readable, if it is not crucial for performance to go another way.Create a new list and add only values to it that are not already included. You can do this with a simple list…
Yeah I know it’s kinda pointless. I was thinking the same thing when I doomscrolled youtube shorts watching a so called programmer “Herr Programmierer” showing a simple script moving the mouse in a fixed interval to coordinates in a fixed square. I was bored, I like Python and sure I could create a better pointless…
Yeah we all can loop, but can you any or all? Checking if condition matches for at least one element of an iterable (e.g. list, tuple, set) In Python you can write that nicer with the builtin method any(): But who doesn’t like a one-liner (that is understandable): Very similar is the case if you…
This covers a very configurable and more complex variant of measuring brightness and turning on LEDs.If you are looking for a more basic variant: It all began with a LDR and curiosity. The result is a night light for a ESP8266 like D1 Mini or Raspberry Pi Pico (W) which compensates darkness with many configurable…
Externalizing the configuration is a good idea. This makes the reusability of your program much higher and a user doesn’t have (and shouldn’t have to) change values in the code.This separation tends to show where your code is perhaps too tightly coupled and constants are referenced directly as they are directly available in the script…
This is a continuation of Is it dark yet ? – Measuring brightness with LDR on Pi Pico (W) and ESP8266 (D1 Mini & NodeMCU v3) in MicroPython, but concentrating on a fast and clean code rather than how to use a LDR with MicroControllers in principle. What you need: D1 mini or a similar…
A follow up to Software tests – some basic JUnit testing in the area of RxJava. Not much text right now, just the announcement, the code below and the link to my github repo. Includes a build.gradle with all the needed dependencies.(There are already some other test concerning ConnectableObservables subscriptions and time of emit.) Short…
