Thread: Good to be a Tech

Tweet

Check out my freebee controller PC. Got ( count em) 4 9 pin serial ports. Thats 128 channels of servo or relay fun. Oh and I just got another PC as well. This one has a Pentium 4 3.5 Gb liquid cooled processor. Just two serial ports, but plenty of USB's.

HEHE it is good to be a tech.

Got 4 flat panels as well. And I still have my older laptop. It's like Christmas. The key is convincing the boss to scrap the hardware for parts. I have some machine power supplies as well. Just need to find out how to bypass the logic board input.

Only drawback is none of this stuff can be sold. That could cost me my job. Ahh such is life.

do what? to turn the power supply on? if so connect the green wire to a black. if that dont work, put a light up auto switch so there is a load on it.

The power supplies I have obtained are used with a machine. They have an on off switch that goes to a logic board. A harness from the logic board plugs into the power supply. So the power supply once plugged in is providing logic voltage to the board, but the board switches on the higher motor control circuits. I may need to get a schematic to use them. Not a big issue. Not even sure what output they provide. Label only shows input voltage.

on a standard ATX power supply the one green wire hooked to a black, the power supply should turn on.

Yellow and black = 12 Volt DC
Red and black = 5 Volt DC
Orange and Black = 3.3 Volt DC

I will take a picture for you to look at. Let me get the case off. I will post later tomorrow.

i assumed in your earlier post the power supply was from a computer, i now read machine. so my guess is i have no clue. best of luck and dont become your own best prop.
