I am going to try it, but I am a little worried looking at all the parts etc. I got my 1st practice soldering my monome grid kit / komaField kit and a couple other very simple projects since then, so I am tentatively confident I can complete the project. Looking at the BOM from mouser has got me wondering if I’ve already gotten something wrong. 
Is anyone else here going to give it a shot?
I would love to get some help along the way…
