I’m having some distress I just place a diy projector together. The only problem is that they question to place the tv upside down. But when I turn it upside down the picture goes green. Please Help Im trying to fix it for my small outside theater.

My sister wants to have a going-green theme for her bat mitzvah but doesnt want it to be weird. Anyone have any thoughts to make it cool and fun for a bunch of 13-14 year olds?
decorations? thanks so much!

Want to add a solar panel to help charge my car battery. Will this affect/hurt my alternator? Do I need to switch from alternator to solar.
I was hoping to place the panel attached to the car all through operation.
I’d like it as simple as possible.

How many solar panels do I need to run my two bedroom townhouse? Are there different solar panels? How many solar panes to produced 1 KW of electricity?
