Iron Pumpkin(s) and other smaller vegetable animals

That was a long day 😀

Double checking and adjustments tomorrow.

I’m not getting any voltage into the reels, i have switches not logic, do I need to connect the ct tap ?

inputs switch (5step) is working with just flat cable

for 24-step volume switch, you need to have connected flat cable to Turtle, and two wires from MoBo

near input switch IDC header on MoBo, you have 2 pads marked as ATT+ and ATT-

logically, solder two wires there and to pads on switch, marked ATTSWITCH+ and ATTSWITCH-
 
you don't need 7805 (for logic 5V PSU) but you need LM317 with accompanying parts, for +24Vdc relay PSU

totally characteristically for ZM - IC1 is typo; it needs to be phrased as :


Relay/Logic PSU

if no logic, you don't need IC2

in that case 24Vac/10VA Donut

connected to AC1/AC2

like this:

ref. to pic above

U=((3K3/180)+1)*Uref

as Uref is typ 1V25, but per datasheet and also in reality, in range of 1V2 to 1V3, everything is as predicted

but, most important - relays are perfectly happy with anything in range od 20-28Vdc, so just chill

and, voltage will practically sag for few hundred of millivolts when reg is actually loaded
