My first thoughts on how to improve alias management in the start-mailserver and check-for-changes scripts are: 1) There should be the built-in idea of "system-managed" aliases, starting from those outlined...

There are shorter diffraction spectroscopes. I just ordered one that is 55mm long. i believe the one in the project is about 3x that long. You might be able to...

My tiny $30 diffraction spectroscope came today. A quick look through it inspires some level of confidence that this little guy can work.  

I think there are at least two things going on with the length. First, the light needs to be collimated. That is what's being depicted in your diagram where the...

If you can find a collimating lens with a very short focal length, perhaps. I'm not an optics expert but this person is: https://www.edmundoptics.com/knowledge-center/video/tutorials/understanding-collimation-to-determine-optical-lens-focal-length/ Edit: what we are discussing here...

Side comment: In my way of thinking, the tube needs not be shorter than the longest dimension of the Pi itself. At least if you are talking about making a...

I think the ones without the IR filter (NOIR) go up to about 880. Not sure about UV but doubtful would be much below 400 unless you had done something...

Here is the code snippet. The code path in question is when scrolling == true (that's when the previous lines get overwritten by the same line drawn in background color)....

And the eraseLine and drawLine methods, which just transform from chart coords (float) back to pixel coords. ``` / Draw a line void ChartXY::drawLine(TFT_ILI9341 &tft, float x0, float y0, float...

It seems the original issue affects at least some other fonts (e.g. FSSB24) as well, it just happens that I was not updating those labels when I first wrote the...
