Build an Off Grid Wikipedia with

We all rely on the internet as a reference library. In those cases when you do not have access to the internet, it's pretty difficult to access the information you need.

Missed opportunity: solar power bank.

[@HobkinBoi]

I doubt it'd be difficult to add this honestly. They make folding solar chargers for USB, that'd work well. Could also use one of those other larger panels in conjunction with a regulator. I just think though that's a lot of wasted space, if you built up your own battery pack, you could make this thing run for possibly days on end. Solar panel would easily extend that. I built a smallish 12v li ion battery bank, combined it with a 10w solar panel, and some regulators, and I was able to run a Pi Zero W for almost 2 full days. The Pi was just functioning as a very dirty FM transmitter. I was out in the woods with literally no other radio sources nearby, so I was not interfering with anything, also the range was only 200-300 feet. If the sun was out more of the day, It'd likely run a third, maybe forth day. So yeah, larger battery pack, and some solar, and boom, you're pretty set.

[@TheMuddman74]

Probably already is and if not it would be really easy. In fact most current electronics wouldn't be harmed by an EMP. The movies and myths are mostly bullshit. I could write a book about this but the quickest gist I can give you is this: Soooo many things give off electromagnetic waves and most electronics would interfere with each other if critical components were not shielded from the electromagnetic pulses as well as other forces. A couple examples would be your car and its ECM/PCM are shielded (no issues). Your PC/Laptop are shielded (no issues). Also EMPs dont effect the batteries, cables, wires, resistors, bussbars, fuses, mechanical switches/relays. Soooo....99% sure this thing is fine already but if you are worried just stick it inside a potato chip bag.

so much potential here. With a bigger case, you can add supplies for repairs, a small solar panels, extra batteries, additional accessories....

Might be smarter to include those in separate cases, that way the main case remains light and easy to carry, and if you lose the supplemental cases, it isn't a catastrophy. If you're going post-apoc, you should have redundancy, and putting all your eggs in one basket isn't that.

[@higihups]

@@Hexen_Wulf I would argue, that a little hinge on the display frame, with a small solar panel hidden behind the display, would not add too much weight or size. You could pop that out and put the solar panel out to recharge. This will also create redundancy, as your hotspot becomes independent. In that situation, even worse than putting all eggs in one basket, is to store the cans in a different location than the can opener.

Some ideas to enhance it: - No movable parts as they can break. So no fan, but passive cooling. Metal box will come in handy for EMP reasons anyways. - Add a solar panel that will keep the battery charged, even if fully empty. Never know how long the Zombie apocalypse lasts. - Include basic programming tools (C++ comes to mind) so it can be expanded if needed. - Here Maps with offline world data.

[@ex1tium]

@@ArnaudMEURET We might be hit by large enough solar flare/EMP to burn our power grids and all the unprotected electronics on the planet. Only way to protect electronics against that is to build faraday cage that is grounded around your electronics. I would just store the computer in another container lined with grounded metal film that acts as faraday cage. You'll lose Wifi and radio if you built it into the computer case itself and grounding it is difficult. Last known big solar flare capable of destroying electronics and power grids of today was called Carrington Event that happened in 1859 and it affected telegraphs all around the world. There have been other big flares but Earth hasn't been directly on their path.

@@ex1tium The earth was directly in path of March 1989 geomagnetic storm, yet Hydro-Québec's power grid was only offline for nine hours while neighboring grids didn't go down at all. The solar storm of August 1972 was even more extreme, strong enough to cause magnetic sea mines during the Vietnam War to spontaneously detonate, but the power grid didn't fail catastrophically. Was the Carrington Event so bad because the telegraph is more fragile and less protected than modern electronics?

Spiffy project. 80GB for all of Wikipedia? I'm floored. I noticed the under-voltage on the display.

Two super caps and a 10W solar panel on the lid, a proper solar charger that regulates to 5.2V directly, then an E-paper display and some serious sleep routines, so the Pi goes into low power mode when not updating the screen. Ditch the WIFi, who carries a phone in the apocalypse? Just put a minimum of navigation buttons on it to navigate the screen and use them for OSK too. They can also have their own micro controller, that wakes up the PI so it doesn't has to pool for key presses constantly. The you have a device that can run in 200 years on a rainy day or indoors infront of a bonfire.
