thanks to you both!
I was just gonna ask the same question!
although I haven't yet built mine... any thoughts about the need to make it more sturdy or adding extra components to make it last longer or do things in a more controlled way? I'm asking this because I'm seriously thinking about making mine as well and from watching youtube videos, I got various kind of homemade ones ranging from easy projects to more complex electronics!
so, is complex worth the effort and why?
