DESCRIPTION:Energy must leave into space so we can communicate\, for that 
 we need antennas.\nThis small workshop will provide a rough introduction t
 o what characteristics an antenna has and how you can build antennas for y
 our devices. And in the end we'll build some antennas together\, so that y
 ou are well equipped for congress.\nWe'll bring a small selection of tools
  as well as supplies\, but we'll be happy if you bring some along yourself
 \, too.\nIf you are a Junghacker:in this session is especially well suited
  for you\, but if you want to join us for the same workshop in the afterno
 on you're as welcome.

DESCRIPTION:### Building Autonomy: Mesh Radio Hardware Workshop\n\nDecentr
 alized communication infrastructures require more than finished devices: u
 nderstanding the hardware level enables critical engagement with proprieta
 ry designs and creates autonomy beyond commercial dependencies. The worksh
 op covers complete assembly of an nRF52-based mesh node in Heltec form-fac
 tor\, where participants gain practical comprehension of decentralized rad
 io network architecture through soldering components\, integrating LoRa mo
 dules\, and installing firmware. Critical decentralization means not merel
 y using distributed networks but mastering their technical foundations: bu
 ilding custom boards reveals trade-offs between energy efficiency\, range\
 , and cost\, enables design adaptation to specific requirements\, and deve
 lops capabilities for repairing and modifying existing infrastructure. Con
 trol over hardware design and firmware variants dissolves dependence on ma
 nufacturer decisions and permits experimental topologies that commercial s
 olutions cannot accommodate. The workshop targets advanced participants wi
 th mesh operation experience\, as technical fundamentals are prerequisite 
 knowledge.\n\n**Prerequisites:** Operational experience with mesh nodes (a
 dvanced)  \n**Materials:** PCB kits available\, pricing will be announced
