I will be writing a script to modify my Teensy LCD Project to receive HW Sysex status information, specifically in this case to turn on four power outlets in sequence when HW sends the Organ Ready status. This is simply a new sketch that will work with or without the PCB board shown in the Teensy LCD thread, so no new picture is needed here. The project will use the Teensy 3.6 as that is the model I have in hand, but there's no reason not to do the same with the 3.5 or the 3.2 versions.
Thanks to Ed for a private message that prompted me to do this. I have automated the power to my amps and powered speakers for years in a similar manner using my own encoder designs, but this will allow adding the feature without purchasing an expensive decoder just for that purpose.
