Embedded nut placement

Devices secured

• note wiring between LM7809 output and device inputs still needed. For input I've included a slot for a 5.5 X 2.1 jack to the left of the XR2206 signal generator and a small opening directly under the LM7809 (for direct wire) as two options. Note LM7809 input should be at least 12V DC - output is described as 9V max 1.2 A

7/30/2019 updated switches will need to be cut out of the cover and the ad-hoc "raft" trimmed off
