This question already has an answer here:
I have started hosting a website on my raspberry pi, but because of the power outages, and mostly because I'm itching for a DIY project I would like to build a UPS for my pi and my router(12v-1,5A).
I have done some research and I found this, but I have no idea if this will work and I can't risk anything because pi's are really rare and expensive around here in Turkey (I know, it sux).
Has anyone built an UPS for a Pi? Do you have any blueprints? What should I consider?
