DIY: How to make fan using popsicle sticks / ice cream sticks – video
Input energy source are solar or battery
Solar fan
Parental guidance required.
Required items:
Popsicle sticks / ice cream sticks
Hot glue gun and glue sticks
Bottle cap
DC motor ( 5 to 9v DC motor)
wires and connector
9v Battery (note battery power will be over quickly if you run the fan for long)
or rechargeable battery to run the fan for long time
We have used Glue Gun, Glue Sticks and Ice cream sticks/popsicle sticks to do the craft shown in the video.
If you know what is the problem in Amps readings please let me know, it is really appreciated!
Seems me that the panels are connected properly, it gives Volts, but no Amps. The connection is the same as here: https://www.youtube.com/watch?v=Hey1QZkYFSQ
Thank you for suggestions!
