From the 1st day of setting up my aquarium I toyed with the idea of having a automated way to lift the hood straight up off my tank with the push of a button. This would allow me to use my large tongs, scrapers, etc. without having to take my heavy oak hood off everytime or struggle to work around my hot MH lights.
Well after a lot of planning I finally came up with a system. It's very similar to the systems used to raise and lower flat panel televisions and it works awesome!!
Sorry about the video quality, I used my digital camera.
