The last parts I needed to finish my solar powered mini perimeter defense alarm systems arrived in the mail. These alarms are very useful for a variety of applications.
I got some flashing red LEDs along with resistors to power them from 12 volts. And my 5 volt 3 Watt solar panels arrived. These are nice quality glass coated solar panels with a USB output port. I got 20 of them today.
These alarms will be placed around our property with a wire attached to each one. When someone or something approaches the wire, an alarm will sound.
These will also be useful for protecting game cameras or around a camp site to alert campers of approaching predators.
If they turn out well, I will produce them for sale.
