Reflow sol dering is also not difficult to do as a hobbyist\, but requires a few more tools like a stencil to apply solder paste and either an oven or a hot pl ate to do the reflowing. It is\, however\, much quicker than soldering the parts one by one\, and can yield more professional looking\, cleaner\, so lder joints.\n\nThe project is an electronic name-badge - You should write your name (or nick) on it and wear it. It contains 42 LEDs\, a microcontr oller\, some support components and an InfraRed transmitter and receiver t hat allow it to communicate with other badges. When the badge detects the presence of other badges ("friends") nearby\, it will change its behaviour . It will not only interact with other 39C3 LED badges\, but also with TBD badges - come visit the TBD assembly at komona or https://tbd.camp\n\n![T BD badge](https://usercontent.events.ccc.de/congress/2025/hub/usercontent/ e/d619de5f1be1/tbdbadge.png)\n\n### Costs\nThis workshop is donation based . Materials costs are 2 euro per badge. Donations will go towards 1) cover ing costs of the badges\, 2) covering costs of running the hardware hackin g area in general\, 3) covering costs of organizing TBD (see the TBD assem bly at komona or https://tbd.camp)\n\n### Registration\nThe number of part icipants per session is limited. First come\, first served. Either get a p articipation voucher beforehand or show up early (there may be places left ).\nThere will be *numbered* paper vouchers available for each session som e time in advance of each session. If you get a voucher and do not show up *before* the designated starting time\, someone else may take your spot. Please don't take multiple vouchers and don't take vouchers if you don't actually plan to participate.\n\n### Getting a kit\nKits are part of the w orkshop and not for sale separately. You can\, however easily source your own PCBs and parts and make kits yourself because the design is MIT licen sed open source.\n\n### Links\nhttps://github.com/hackwinkel/39C3LEDbadge \n LOCATION:Hardware Hacking Area -- Rear URL:https://hub.test.c3voc.de/en/event/detail/39c3-led-badge-smd-for-begin ners-day-1 END:VEVENT BEGIN:VEVENT SUMMARY:Is That an Off-Grid Server in Your Pocket\, or Are You Just Happy to See Me?

These little devices can be used to message each other and build a network utilizing only some small antennas without the need of internet or a phone network. Together\, we will build our own solar powered outside LORA nodes that can be used with mesh softw are such as Meshtastic\, Meshcore or Reticulum without the need of a power outlet. We will bring the required parts and an easy to follow "how to" m anual. There will be little to no input but we want to create a cozy atmos phere to come together to learn\, to solder and teach ourselfs how to crea te our own communication devices from scratch (well at least almost). We w ill start at 23:00\, feel free to stay until you are done or finish in on your own time.\n\nEach node will consist of a solar panel\, a low power lo ra node (XIAO nRF52840 & Wio-SX1262 Kit)\, batteries\, an antenna + other connecting components such as cables and a charging controller to make eve rything work together nicely. We have tried to keep the cost as low as pos sible so we used the cheapest components we found\, for long term use you might want to upgrade some components.\n\nThere will be only a limited amo unt of seats available. Please come to the hardware hacking area one hour (22:00) before this workshop starts to get the hardware (35€\, cash pref erred).

You will solder a custom PCB designed to light up and connect a Pusheen cat lamp. Once assembled\, we will flash it with WLED\, the industry-standard open-s ource software for controlling addressable LEDs. You’ll leave with a lam p you can control from your phone to display rainbows\, fire effects\, and notifications. It also doubles as a Wi-Fi defender\, with firmware to det ect and warn you of the presence of Wi-Fi jamming attacks!\n\n**Registrati on**: \nBuy a kit at the Hardware Hacking Area or website to guarantee a seat\, or come by early!
