If you post what you need (probably in beginners) or want to do I expect some of us will make suggestions. Since I have no idea what a Star Trek TNG Phaser power readout looks like you would need to describe what it needs (such as a bar graph display where light moves up or down the bar to indicate power). Given that we can probably point you in the right direction. Welcome aboard.
edit: If you aren’t already aware of it, you may also want servo magazine:
they are running a monthly column on prop building which sounds like what you are trying to do. As part of that there are lots of pointers to other resources that may be interesting.
