Review of a 12V splitter. This is also called a 3-way cigarette lighter adapter .
12V adapter-splitter review
This adapter plugs into a single 12V battery outlet and splits it into three outlets. Could be used to power three gadgets from your car or from wherever else you have a 12V outlet. I have one in my house for off-the-grid backup power.
Video review…
The solar lights on my property have been dim or have been completely off at night. Maintenance can be done on these lamps to get them working again.

Make Your Own Air Battery
The video below shows three different electrolytes for a cell. Which electrolyte will be the best, producing the most voltage and current?
Making a waffle out of sodium acetate trihydrate. This is the same stuff that makes up “hot ice” and heating pads.
How is the liquid made?
Acid can release electricity from metal. What is an easy-to-find source of acid? Tomatoes!
The video above shows how an LED and a buzzer are powered by a tomato battery. It’s just two different metals dipped into mashed tomatoes. It even helps charge a AAA battery.
How does this work?
The video below shows how to make a combiner box to allow solar panels and a wind turbine to charge the same battery. Also shown in the video: How to make an extension cord out of spare CRT cables and heat shrink.

I am documenting the construction of my first wind turbine. I am not an expert, just learning as I go. I am not building a turbine from scratch, but instead trying to first succeed in mounting one to a tower and wiring it up to power small devices inside my house.
