To anyone who wants to bring their why2025 badge to 39c3, don't forget to bring your antenna. If you don't have yours anymore, I am bringing a few kits with an antenna and connector (thanks to @a51c ).
I have 7 of them with a half-decent antenna for €6, and 2 of them with a the original badge antenna for €3.
The LoRa module on the badge also requires two bodge wires to be soldered. Two pieces of wire and instructions are included in the kits.
On some badges it may be required to remove some epoxy around one of the battery holders, and even if it isn't, it may make soldering the bodge wires easier. You may also want to make your badge safer and more compact by removing the battery holders entirely.
I am also bringing some epoxy removal kits for free (they're just alcohol wipes and disposable vinyl gloves).

@Peetz0r @a51c Please re-apply epoxy after removal, to keep the fire protection active. (If not removing the battery holders entirely.)

@Peetz0r Do you have any tips on removing the cured epoxy? My wireless chip is covered in it.
