Let's build mesh radios from scratch.
We will bring 20 PCB kits, containing all parts. Soldering is difficult but doable in the Congress. You have to be very proficient with soldering to get this done during Congress, but the Eternal Soldering Workshop is open and nearby.
We also have solder paste and stencils for the real pros!
If you don't want to get into soldering now, you can take one of the kits home. During the workshop you will get to know everything necessary to get the job done.
