Creative Sunday: DIY Power Backup System
from olujay 3Speak Podcast Hosted by olujay
I got my new internet router to solve the issues with low range on my old one. A new issue arose with this one, however, and it's with power.

It runs on 12 volt DC power, and power banks usually give 5 volt DC. I needed to find a solution to keep the new router running much longer, especially during blackouts. I improvised. I thought of the things I had at home, and then I remembered that we had a car battery and a generator battery that are 12 volt DC rated, and then a light bulb came on: a simple circuit to draw power from those batteries into the router should suffice. And, considering that they were even bigger batteries, I had nothing to worry about. The video here is a concise compilation of clips from when I was designing. The simple circuit to do my bidding.
