controller and drives are sata . . . but, your general point that there are only two led circuits seems right, so there's no way i'm pulling...
i'm measuring voltage just between the pin and ground, i.e., with no led in the circuit. its the tx4, the manual indicates that those are for...
i have a promise sata four port controller. it has a four pin output for hard drive activity. from what i can tell two of the pins are 'idle' at...
:blush:
Could I just use a smaller resistor at R2, say 1000 uF, to get faster discharge? I'm not sure I understand the transistor discharge method;...
What purpose does R2 serve in this schematic? Is it just for the capacitor to discharge over when the circuit is off?
Ah, right. But if had my kickstart bypass the resistor until the fan got going I'd avoid that problem. Btw, is the increased current draw caused...
thanks for the welcome! and the schematic looks good too. especially since this is a low resistance fan -- around 40Ohms by my calculations.
I thought a resistor would be OK because I don't plan on changing the fan (or adding any more in series). Is there any other reason not to use a...
OK, I feel like this has to have been mentioned (shot down?) before, but I haven't found it anywhere. Typical problem. I want to lower the...
