The bill of material is 100% complete. After some initial testing, it appears that everything I initially purchased will work as intended.
The electronics are almost fully assembled. The LEDs still need to be wired to a relay, but the relay clicks in synch with my heartbeat.
Testing has been completed minus the LEDs. I don’t imagine running into any issues when the LEDs are wired up to the relays.
Once the electronics are verified to be working, I will assemble everything else, including the valve cam cover, the plexiglass back plate, and the mounting of the LEDs. I have allocated 3 days to complete this activity.
