Picture of Using A Voltaic Solar Panel For An EL Wire Logo
For the March Build Night with Voltaic Systems, we thought it would be great to use the 6 Watt system they sent us to power up the Omaha Maker Group EL Wire Logo that hangs in our front window.

The Voltaic Systems 6 Watt kit comes with their 6 Watt Panel and their V15 Rechargeable Battery, plus a variety of cables and connectors. The panel charges the battery, which functions like a typical external battery pack common these days with smartphones and mobile devices. The output of the battery is through a standard USB plug.

The EL Wire logo is powered by an inverter that runs off of (2) AA batteries. Since the inverter is necessary for the operation of the logo, it needs to be kept. But the batteries could be replaced by the power from the V15 Rechargeable Battery.

I think so. You'd have to check the load ratings to be certain. Also, there are versions of the buck that include a voltage display. Those might be best for your application.
Thanks for the comments!
Thanks for this! I love your idea of using the buck converter! Can this be used to turn a wall wart into a variable power supply?

As long as the sun shines, anyway!

Looks like that's an 'always-on' lightbulb....quite literally.
