First power test of the Indoor Light Charged Power Supply.

A project log for Indoor Light Charged Power Supply

Open source, easy-to-build Power supply charged by ambient indoor light to power low power micro-controller projects and an external device.

After hours of sitting in indoor light to charge the super capacitor for the first initial charge, the Indoor Light Charged Power Supply is ready to test. I tested the power supply on a clock from my work bench. As expected, the output from the electrolytic capacitor powered the clock as it discharged, but when the load was removed, the charge started to build up.

With the clock connected to the super capacitor’s output, the clock was also powered but with very little drop in the super capacitor’s voltage. Check out the video.

Now, to power some micro-controller projects.
