Dev Containers, Podman and WSL 2

Although I am not a software developer, every now and then I tinker with software. When I do so, I tend to end up with a whole bunch of software, modules and add-ons that need to be installed before I can start to do what I want to do. After a while, my computer is a big mess and the next thing I try is impacted by whatever I did some time ago and forgot about.

There must be better ways of doing this right? Yes, there are better options and I have tried a few of them over time. The latest and greatest option: DevContainers. Let me introduce you to what I did and learned recently.

Assemble the name sign

Thursday 6 May 2021

It took over 165 hours to print all the parts of the name sign. By now I have:

  • 5 parts that make up the backside of the name sign
  • 5 parts that make up the casing of the characters
  • 16 parts that make up the fronts of all the characters
  • 5 parts that make up the QR/electronics box.

And I have 171 LEDs that need to get in there and need to be connected to the microcontroller.

Time to assemble the name sign.

Finalizing the design of the name sign

Tuesday 4 May 2021

By now, it is clear how the name sign should look like and we now know how the LEDs behave and how to diffuse the light. And since I did some test prints, I know that the individual parts seem to work. Time to work out all the nitty gritty details of the design and prepare the 3D print files.

Light diffuser

Each character of the name sign will get LEDs to light them up. By now, I know how to control the LEDs using a microcontroller. And I have a LED-matrix that I can use to figure out how much light is generated by the LEDs. It’s time to figure out how to diffuse the light and this is also a good moment to print out a character to see if the parts fit.

Lights on - lights off

Sunday 21 March 2021

Now that the outline of the name sign is clear, it’s time to look at the next topic: how to add light to it? I want to be able to control the color of the LEDs, I will need to investigate how to do that. And I need to figure out how to make sure that the front of the characters diffuses the light so that the individual LEDs are not showing.

A quick search on the Internet showed that LED strips differ by the amount of LEDs per meter. This means that I also need to figure out which one to buy. Since I have no clue how much light these strips produce, nor how much light will be lost by the front of the characters, I will probably have to experiment a bit to find the answers.
