Low to High power GPO mods... need help.
Low to High power GPO mods... need help.
Ok, here is the deal. I still have my awesome LK202-25 serial LCD and I'm in the process of modding a new case (Chieftec Matrix Full tower).
I've been thinking for a while to do this but the time has now come; I want to let the LCD control the neon lights in the rig through the GPOs. I've been looking at the low to high GPO mod but I'm not sure I wanna go that extreme.
I was thinking about using a relay that takes in the power from the GPO on one side and the 12V from the PSU on the other hand. Now, I simply have no clue on how to calculate the relay value (I'm not the best at this) so I was hoping someone could point me in the right direction.
Next, I'd like to add a single press button connected to the keypad so that when pressed LCDC would send a signal to turn of both the LCD and GPO controlling the neon lights. Would this work? Do I just need a switch and connector for the LCD (I was thinking about using "F" as both pins are next to each other).
Finally, I was wondering if there were significant differences between the serial LCD models and the newer USB. Is there any conversion kit available?
Thanks for the help (Henry maybe...).
Cheers,
Sam

I'm not an electronics man - so I can't answer, but the bit article is pretty easy to be honest.

Yes, you can find relays that will do 5V input and do 12V and high current out. just remember that the GPOs on the LK202-25 are 5V and supply a maximum of 20mA. With these numbers you should be able to find what ever you need from Digikey or Jameco.

Excellent. Thanks Henry for your help.
Now just as your opinion, do you think this solution will work properly enough to turn on neons?
Also what are the differences with the newer USB model?
Finally, I really like the High Voltage mod, and was wondering how hard it would be to modify it so that the GPO outputs some 5V, 7V and 12V so that depending on the system temp you could apply a different voltage to fans. That'd be real nice. Anyways, wish Matrix Orbital would sell those boards as an option.
Thanks again,
Sam

Thanks Miles. Will look into that. Do you happen to know where I could possibly find it?
Also, I might be selling my LK202-24 and get an LK204-25PC Limited edition instead which I believe wouldn't require me to use a relay, but I was wondering if this model will ever be available in blue color (blue background, white text) and with USB interface.
Thanks again for the suggestions,
Sam
