Router fence hack - Once the fixed fence is clamped in place, the microadjuster dials in the precise fence location. This is especially handy for making multiple passes at increasing depths, should you own a small-motored router or need to hog away large amounts of material.
If you have a mount for your TV, fasten all of the electronics with the unsightly wires to it. (If you need to, build a small lightweight frame to attach to your mount.) Bundle up the wires as much as possible before fastening them to the mount so they don't get tangled once they're up there. Use bungee cords to secure heavier hardware like a cable box or router. Plug everything into a power strip so you only have to worry about one wire running from your TV to the wall.
