Don't let this scare you! I've taught tens of thousa nds of people to solder\, most of whom have never made anything before in their lives. It is actually a very easy skill to learn. It is also very us eful.\n* Then we will each make our own Arduino clone from a kit.\n* Now t hat we each have our own Arduino board\, we will set up the free and open- source *Arduino software* on our laptops (if you bring one) -- Windows\, L inux\, and MacOS are all fine!\n* And then its time to make something and learn how easy it is to use Arduino! I'll (very easily!) show you how to r ead schematic diagrams\, and you'll put together your own TV-B-Gone remote control using your Arduino clone board. We will use a solderless breadboa rd. These are really useful\, and provide a fast\, and very easy way to pu t circuits together without needing to solder.\n* Target practice is avail able all over the world after the workshop.\n \n**Registration**: \nBuy a kit at the Hardware Hacking Area to guarantee a seat\, or come by early!

Reflow soldering 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 plate to do the reflowing. It is\, howev er\, much quicker than soldering the parts one by one\, and can yield more professional looking\, cleaner\, solder joints.\n\nThe project is an elec tronic name-badge - You should write your name (or nick) on it and wear it . It contains 42 LEDs\, a microcontroller\, some support components and an InfraRed transmitter and receiver that allow it to communicate with other badges. When the badge detects the presence of other badges ("friends") n earby\, 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![TBD badge](https://usercontent.events.c cc.de/congress/2025/hub/usercontent/e/d619de5f1be1/tbdbadge.png)\n\n### Co sts\nThis workshop is donation based.

In Ireland\, official air quality monitoring relies on a limited number of sensors\, so local and short-term pollution sources can be missed. In t his 90-minute\, hands-on workshop\, you’ll build your own particulate ma tter (PM2.5) air quality sensor using a kit of off-the-shelf parts\, then connect it to the Internet so you can view and share the data.\n\n## Senso r.Community\n[Sensor.Community](https://sensor.community/) is an open\, gl obal citizen science network where people build low-cost sensors and share environmental data. Once your device is online\, it can publish readings so you can track trends over time and compare data across different locati ons.\n\n## What You’ll Learn\nDuring the workshop\, you’ll assemble a working PM2.5 air quality sensor and get it online. We’ll cover the basi cs of IoT devices\, local data collection\, and how to publish readings to Sensor.Community. You’ll also learn what the numbers mean\, what these sensors are good for\, and where their limits are.\n\n## Materials\nYou’ ll work with:\n- ESP8266 board\n- SDS011 particulate matter sensor (PM2.5 and PM10)\n- BME280 sensor (temperature\, humidity\, air pressure)\n- USB cable\n- Jumper wires\n- Plastic tube (air inlet)\n\n## Requirements\n- A device with a web browser and WiFi\, such as a phone or laptop\n- All setu p is browser-based\, no software install needed\n- No previous experience required\, beginner-friendly\n\n## Materials Costs\nIt costs **€60** for a kit to take home.\n\n## Instructions\n[Slides](https://docs.google.com/ presentation/d/1H4KuVn2qhhqdg9caCRLc4V6N_QEV1xoevmVM4edoR44/edit?usp=shari ng)\n\n## Facilitator\nTaught by [Jeffrey Roe](https://chaos.social/@tdr11 2).\n\n**Buy a kit at the Hardware Hacking Area to guarantee a seat\, or c ome by early.

These little devices can be used to message each other and build a netwo rk utilizing only some small antennas without the need of internet or a ph one network. Together\, we will build our own solar powered outside LORA n odes that can be used with mesh software such as Meshtastic\, Meshcore or Reticulum without the need of a power outlet. We will bring the required p arts and an easy to follow "how to" manual. There will be little to no inp ut but we want to create a cozy atmosphere to come together to learn\, to solder and teach ourselfs how to create our own communication devices from scratch (well at least almost). We will start at 23:00\, feel free to sta y until you are done or finish in on your own time.\n\nEach node will cons ist of a solar panel\, a low power lora node (XIAO nRF52840 & Wio-SX1262 K it)\, batteries\, an antenna + other connecting components such as cables and a charging controller to make everything work together nicely. We have tried to keep the cost as low as possible so we used the cheapest compone nts we found\, for long term use you might want to upgrade some components .\n\nThere will be only a limited amount of seats available. Please come t o the hardware hacking area one hour (22:00) before this workshop starts t o get the hardware (35€\, cash preferred).

Reflow soldering 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 plate to do the reflowing. It is\, howev er\, much quicker than soldering the parts one by one\, and can yield more professional looking\, cleaner\, solder joints.\n\nThe project is an elec tronic name-badge - You should write your name (or nick) on it and wear it . It contains 42 LEDs\, a microcontroller\, some support components and an InfraRed transmitter and receiver that allow it to communicate with other badges. When the badge detects the presence of other badges ("friends") n earby\, 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![TBD badge](https://usercontent.events.c cc.de/congress/2025/hub/usercontent/e/d619de5f1be1/tbdbadge.png)\n\n### Co sts\nThis workshop is donation based.
