Greetings; It is not quite as I expected it to be, it seems both leds are on a common substrate so they cannot be treated in the totem pole config I had in mind for active drive in both directions.
Ditto the output side, supply and + source voltages are apparently hitting the same cell substrate, both cells are used to crowbar the drive to transistor the output, which itself is a 10k pullup from the collector of the transistor. So it doesn't invert the signal. So I have obtained 3 pink spade lug terminals, and only wired the single output to where the arm of the speed pot would connect. The sparkfun board are quite small, and it is currantly wedged between the three spade terminals, being held by both friction and a glop of locktites goop on each side. As the input buildout of the gemini driver is around 30k, that means I will be getting around 9 volts for full on, I hope the gemini drivers gain pot can fix that. I don't know if that will reach full speed or not because I'm spending time remounting the motor and jackshaft to reduce the push against the front lower pulley flange. And I may yet order a belt at least 2 teeth longer if this belt turns a ragged edge in a hurry because I have had to raise the motor by around 3/16" so its hitting stuff on the covers. My back is done for the day, but there are more cover mods to be made yet before it will be ready to cover fully and power up. I get an MRI on the back Tomorrow, its bugged me for 55 years now. Thats long enough to grin & bear it. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
