Solar Powered Clock

Hi,

As this is my 1st instructable and I am still a 7th grader so there may be a lot of mistakes in this instructable and so please do not hesitate to correct me.

This is a solar powered 1.5 Volt clock and it requires minimum components.

Step 1: Materials

This clock requires

@ A 1.5 v clock

@ A 220 k resistor

@ A 9 v solar panel

@ A multimeter (you can also use an ammeter and a voltmeter)

Step 2: Solar Panel Setup

Keep the panel in a place where it gives out 2.5 v. I couldn't measure the current because the ammeter function in my multimeter is not working. Can anyone test it and give it to me in the comments below?

Step 3: Connections

Connect the resistor as shown but do not solder because you may have to remove the resistor in night time , connect the wires directly and keep the panel in a place where there is a bit of light. Sorry for this drawback. But if a light is on in the house you do not need to do this work. What needs to happen is output of 2.5 volts from the panel.

I hope someone can help me develop it more.

My 1.5 Volt clock can be operational from 0.9 Volts to 2.0 Volts.

Step 4: And Its Done

You can now use this clock for a long time without the hassle of changing batteries.

Thank you
