I'll be adding more details here soon.. I'll be adding photos and better instructions as well..
I started this project so I could share a method that seems to work pretty well.. I had a need since I wanted to make PCBs for the ramanPi and quickly discovered my previous methods fall short.. Hope this helps someone else too.. I'd love to hear suggestions if anyone has anything to add here!
Keep an eye out for more ramanPi development too.. !
