Hey again, so I'm making a sputnik probe for myself, and i decided to go the extra mile and make a etched PCB board for it.
So of course there no schematics of the thing around
... lol
So i drew up one of what i knew from reading of people doing it the most simple way, just a resistor to the MPX01 point on the Drive mobo. But i see that the Sputnik Probe actually has a LED that lights up when you touch the probe to the appropriate MPX01 point. So that's what my question is.
Here's my schematic:
I tested the MPX01 point to ground with my multimeter and the point gives off about 3.1V, so can i just put a led between the probe and the GND from the resistor, like in the second schematic on the image.
I see that the sputnik original has i think 2 transistor in, can anyone identify them maybe? or send me a nice close up pic of the tracks.
Thanks
