Today I ordered the final component for the "Wall of Lights" project. I've decided that it is worth getting proper devices where mains is concerned so I've plumped for a nice little Mean Well power supply that can deliver 20 amps at 5 volts. This should be comfortable with the 300 or so coloured leds that I'm going to be plugging into it as part of the Light Mesh project. With a a bit of luck it should arrive in the next couple of days. I'm hoping to get the thing going before christmas.
