Hi All, I just finished my Midiphy build and just wanted to share my experience with building this box to you. - Building is quite easy, i did my build in around 18 hours with a lot of testing etc. between. - Soldering the SMD parts i did with 0.5 tin and i really recommend using a flux pen for the IC's . It makes the soldering so much cleaner. For the soldering of the IC's i used a Gullwing tip on my iron after looking at this video ( https://www.youtube.com/watch?v=oKHsfTH_PvI )
