Machine Log is an excellent blog about restoring ancient video and audio equipment and sometimes building rad projects too. I love the attention to detail and appreciation for the forgotten age of beautifully tied off colour coded wires and hand drawn copper traces.
A project that recently caught my eye is a 360 degree rotating cradle to allow point unrestricted tilting of a video camera for video feedback. This is an incredibly useful project as there are literally thousands of permutations and patterns available by changing the angle of the camera and screen.
Also this modular video processor is an interesting piece of broadcast kit
