Since I'm so new to all this lighting stuff, I've found myself spending the majority of my time hooking and unhooking different components to test with. I got tired of soldering and cutting and splicing to only end up undoing it after my bench testing was complete. I whipped up this little testing rig, which gives me aligator clip outputs for 5V and 12V power as well as two sets of screw terminals for each 5V and 12V. The only thing I wish I would have done different would have been to add a 120V on/off switch between the power plug and the power supplies so I didn't have to plug and unplug often, but that's an easy future addition. It might look very homemade, which it is, but it sure saves me time and serves the purpose!
