DarkPi

Raspberry Pi based modular meshnet

Trio (Design) —

This post was prompted by impending homelessness, worry that I wouldn’t survive the outdoors, and a desire to make development information freely available.

It’s called the DarkPi:Trio, and it’s the result of several years of thought and effort.

Want to see what it’s running on the backend?
Go take a look at the dev branch of functions.sh, it’s all going in there.

Three raspberry pi systems connect to a USB hub, a Hex router from Mikrotik, and a long range mesh networking and comms array. A trio of vape battery cells and a half dozen supercapacitors apiece ensure that the device can gracefully deal with brownouts and external power loss.

The three physical devices perform cross-checks and aggressively re-deploy (using a script-assembled SD card image written to the “OS” portion of the system partition(s)) if any weirdness or corruption is detected. As long as at least one of the three systems is online, the user experience doesn’t degrade under light to medium load.

The raspi units (and modular bits, eg the USB hub) are intended to be hot-swappable, but I encourage you to avoid unplanned power loss for the sake of your SD cards.

The DP:T is just a computer core.
But it’s a computer core with a purpose.
