I built an offline "internet in a box" for SA: Wikipedia in 4 languages, live GPS maps and 80+ guides with zero signal. There's a live demo. Be brutal

Hi all

Joburg guy here. Over the last while I've been building something in my spare time and it's finally at the point where I can show it off and take a beating from this forum.

It started with two annoyances. First, load-shedding taking out fibre and mobile towers at the same time, so even "I have data" stops meaning "I have internet". Second, trips into the Karoo and across borders where there's no signal at all, and suddenly you can't look up anything, not even a map.

So I built Arkanet. It's a Raspberry Pi in a case that broadcasts its own Wi-Fi hotspot. You connect your phone or laptop to it like any other network, open a browser, and you get a local library that needs no internet, no SIM and no data:
  • Offline Wikipedia in English, Afrikaans, isiZulu and isiXhosa, plus Vikidia (the kids' encyclopedia)
  • Offline maps covering South Africa and the surrounding Southern African region, with a live "you are here" GPS dot. Your phone's GPS works fine without signal, the device just serves the map tiles it normally can't download. No hunting for a new map download when you cross a border
  • Load a GPX or KML route onto it, or draw one by tapping the map, and every phone on the hotspot sees the same route and waypoints. One person plans, the whole group has it
  • Wikimed offline medical reference, and Wikivoyage travel guides
  • A curated phrasebook in Afrikaans, isiZulu, isiXhosa, Sepedi and Setswana, everyday and emergency phrases, human-curated rather than machine translated
  • 80+ practical guides: solar and inverter setup, load-shedding management, water, off-grid living, food preservation, plus a proper collection of SA recipes
  • Wikibooks and Wikiversity for students
To be upfront about what it is NOT: it does not "replace the internet". No email, no WhatsApp, no live anything. It's a curated offline library and map server. I think that's exactly what you want when the network is down or absent, but I'd rather undersell it than overclaim.

You don't have to take my word for any of this. There's a live demo of the actual interface at demo.arkanet.co.za, so go break it before you comment.

Everything on it is properly licensed for redistribution (CC BY-SA, public domain, ODbL etc). That constraint shaped the whole content selection and it was honestly the hardest part of the project.

It runs off a normal USB power supply or a decent power bank, so it works during load-shedding by design.

I'm selling assembled, individually numbered units at arkanet.co.za (R3,999 for the Special Edition). It's early days, first units are out in the wild. But I'm mainly posting here because this forum will find the holes in it faster than anyone else.

So: AMA, and be brutal. What's missing? What would make this actually useful to you, or what makes it a hard pass? Happy to go into the technical weeds on the stack (Kiwix, MapLibre, PMTiles, nginx) if anyone's interested.

Photos attached.

This is amazing! looking forward to getting my hands on one. Am I correct to assume that when the internet is available, the library updates itself?
 
I'll be impressed when you have handwritten Wikipedia onto stone tablets. Your box will just die with the first emp.

To answer your question about updates: The feature of this being completely offline means that updates are a bit of a more difficult mechanic. Currently we do offer updates to previous buyers, but it requires a re-download of the image and re-flash the SD card (or you can ask us to ship you a new SD card with the updated image). We are looking into ways of updating in a smarter way, by allowing users to plug their device into their router via Ethernet, but that feature hasn't been completely fleshed out yet.

Haha I know you are half-joking, but one of our clients actually bought a "Faraday Bag" off Takealot that he stores his Arkanet in. We haven't done any EMP testing on these bags though, so buy them at your own risk ;)

How much adult content tho?
None shipped, and that's a gap in the market I'm happy to leave open. Serious answer since others might wonder: the curated content (guides, translations, recipes, maps) contains nothing adult. Wikipedia and other wikis are the full, unfiltered encyclopedias though, same as online, so the usual parental judgement applies there. It's built to be the thing you hand the whole family during load-shedding.
 
Same as this, nice to have local content though.

Yes exactly, a lot of effort was made to make this device actually valuable and unique for South Africans:

- Wikipedia in English, Afrikaans, isiZulu and isiXhosa
- Maps of Southern Africa with cross-border coverage instead of US-centric content
- A Beta translation tool between the 6 most popular languages in South Africa
- Popular SA recipes
- All curated survival guides have been tailored for South Africa
- Local pricing and no import duties
 
Very cool.

There are som HAM radio maps as well. Not sure how free they are but that would be a cool and useful addition.
 
Now link it to a decent multi band radio to enable talking to, and exchanging updates with other preppers…

Looks like you are having good fun 👍🏻

That's a great idea, and hams are exactly who I imagined using this in the bush. The honest constraint is that everything on Arkanet has to be properly licensed for commercial redistribution (public domain, CC BY, ODbL etc), and repeater directories tend to be community databases with murky terms, so I'd need a clean-licensed source. If you know of one, I'm genuinely all ears. Adding it to the list either way!
