Title is a little sensational but this is a cool project for non-technical folks who may need a mini-internet or data archive for a wide variety of reasons:
“PrepperDisk is a mini internet box that comes preloaded with offline backups of Wikipedia, street maps, survivalist information, 90,000 WikiHow guides, iFixit repair guides, government website backups (including FEMA guides and National Institutes of Health backups), TED Talks about farming and survivalism, 60,000 ebooks and various other content. It’s part external hard drive, part local hotspot antenna—the box runs on a Raspberry Pi that allows up to 20 devices to connect to it over wifi or wired connections, and can store and run additional content that users store on it. It doesn’t store a lot of content (either 256GB or 512GB), but what makes it different from buying any external hard drive is that it comes preloaded with content for the apocalypse.”
That doesn’t take much power, a solar panel or two should be more than sufficient, or you can rig something up w/ a defunct ebike (just run the motor backwards to generate electricity).
If the monitor draws even 20W, you’re gonna be tired of that eBike generator solution really quick.
You’d be charging a battery, not running directly off the bike. Still, solar panels are extremely cheap these days. I picked up a 120 watt panel for 50 bucks recently, it could keep something like this running for hours each day.
So, I believe a tolerable generator load for most people to pedal is around 10W… battery charge / discharge is maybe 80% efficient, so you’re netting 8W into your storage. Pedal relatively hard for an hour and you might get 20 minutes use of your IPS LCD screen.
Solar panels are indeed the way to go.
I mention ebikes because if we’re in an apocalypse situation, your solar panels may not be very efficient. There are a ton of electric motors out there, so generating power is totally feasible in a prepper situation even if the sky is torched Matrix style, just attach any electric motor to a bicycle and you’re good to go (or water or wind turbine, etc).
This unit can connect to a cell phone, that’d be a much less energy-expensive way to interface with it.
