How do you get the light to show other colors? I only see red and slight green occasionally

The color is based on how 'strong' your fruit battery is. There is actually a grid that you can find online that tells you the acidity (or strength) of your battery based on which color you are able to get your light to shine.

Is there a trick to make the light work? i tried with 2 lemons and 3 potatoes and nothing worked! the clock did work! thanks! floren

Need more fuirt 4 to 5 work nest

How long will the clock run using an orange or other fruit?

We haven’t done more than a few minutes with the clock hooked up at a time. Sorry.

How many volts do the leds require?

I don’t know the exact voltage. It must be very low. It works with a few potatoes, pineapple and some other fruits.
