    Call or Signal Box for Warehouse

    I may have a fundamental misunderstanding regarding voltage drop. I need about 0.5 amps to power all the devices, but is that the number I should use in calculating voltage drop, or should it be dependent on my power supply? I really feel like I should just experiment to figure it out instead...

    Electronics 101

    I'm 24 and a very hands-on, DIY, self-learner. Lately, I've been feeling like I don't know enough about electronics. Electronics and computers dominate our lives and I hate that I don't have the knowledge to build anything more complicated than a lamp. I would love to know how to design basic...
