I have some old Dell Laptops laying around and they are obsolete to the point of uselessness, and I thought it would be nice to convert one over to a portable monitor/keyboard/mouse like a rackmount console, but way way cheaper.
I know you can get the LCD to work using an LCD controller board, but what I'm trying to figure out is the best way to handle the keyboard mouse functions.
And no, VNC/RDC and software KVM applications will not work, this will need to be able to view and configure the pre-boot screens.
Basically what I would want is for the laptop keyboard/track pad to be recognized as an ordinary USB keyboard by another computer and as far as I know the only sure way to do this is to make a custom arduino or other DIY board to act as a controller and send the keyboard via USB. However, I wonder if there is a way to send keystrokes over the serial port. That of course would still require another device to relay the keystrokes, but would mean less physical modification and leaving the possibility open to use the working laptop hardware for other things. Furthermore, a device intended for relaying keystrokes over the serial port should work just the same on any laptop or PC that has a serial port.
In the end, I just want something that will function reliably once it is finished. Thanks in advance.
