"description": "### 39C3 LED badge -- SMD for Beginners\r\n\r\n\r\n\r\nSurface Mounted Devices (SMDs) are small compared to Through Hole (TH) electronic components, and have the reputation of being difficult to work with as a hobyist: Difficult to see and handle, when you sneeze, you loose them and you can not easily use them on 2.54mm raster prototyping boards.\r\n\r\nSMD components are designed to be used in a reflow soldering process where tiny dots of solder paste are applied to a Printed Circuit Board (PCB), after which the SMD components are \"Picked and Placed\" on the PCB, after which the whole PCB is heated to the melting point of the solder (\"reflowing\"), actually completing the electrical connections.\r\n\r\nThis workshop is aimed at showing you that the reputation of being difficult to work with is a bit undeserved, and that you can also work with SMDs using just a regular soldering iron: With some simple tricks and a suitable selection of components (not the smallest possible), the vast majority of people can successfully complete this project.\r\n\r\nBeing able to solder SMD projects using just a simple soldering iron will also help you develop some skills that are useful if you need to do \"rework\" on reflow soldering projects. 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, however, much quicker than soldering the parts one by one, and can yield more professional looking, cleaner, solder joints.\r\n\r\nThe project is an electronic 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\") 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\r\n\r\n\r\n\r\n### Costs\r\nThis workshop is donation based. Materials costs are 2 euro per badge. Donations will go towards 1) covering costs of the badges, 2) covering costs of running the hardware hacking area in general, 3) covering costs of organizing TBD (see the TBD assembly at komona or https://tbd.camp)\r\n\r\n### Registration\r\nThe number of participants per session is limited. First come, first served. Either get a participation voucher beforehand or show up early (there may be places left).\r\nThere will be *numbered* paper vouchers available for each session some 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.\r\n\r\n### Getting a kit\r\nKits are part of the workshop and not for sale separately. You can, however easily source your own PCBs and parts and make kits yourself because the design is MIT licensed open source.\r\n \r\n### Links\r\nhttps://github.com/hackwinkel/39C3LEDbadge",

"description": "**[Arduino](http://arduino.cc/)** is an amazingly powerful tool that is very simple to learn to use. It was designed so that artists and non-geeks can start from nothing, and make something cool happen in less than 90 minutes. Yet, it is powerful enough so that experienced expert geeks can use it for their projects as well. \r\n \r\nThis workshop is easy enough for _**total newbies**_ to **learn all you need to know to get going on an Arduino.** \r\n \r\nParticipants will make their own Arduino clone, and set it up on solderless breadboards to make their own [TV-B-Gone](http://www.tvbgone.com) remote control to turn off TVs in public places -- a fun way to learn Arduino (and electronics) basics. \r\n \r\n**Materials costs**: \r\nThe workshop is free, but if you would like to partake in the hands-on aspects of the workshop, Mitch will have materials for **€40** (useful for making many different cool projects). \r\n \r\n**Taught by** [Mitch Altman](http://en.wikipedia.org/wiki/Mitch_Altman). \r\n \r\n_**Optional**: Bring your laptop if you want to go home with the free Arduino software installed on it. \r\nArduino software runs on Windows, MacOS and Linux._ \r\n \r\n**Workshop page:** \r\n[Arduino For Total Newbies workshop page](http://cornfieldelectronics.com/cfe/projects/tvbg_arduino/tvbg_arduino_workshop.php) \r\n \r\n**Workshop Itinerary**: \r\n* Intro to Arduino\r\n* Very short lesson to learn everything you need to know about electronics!\r\n* Then we will learn to solder. Don't let this scare you! I've taught tens of thousands 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 useful.\r\n* Then we will each make our own Arduino clone from a kit.\r\n* Now that 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, Linux, and MacOS are all fine!\r\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 read schematic diagrams, and you'll put together your own TV-B-Gone remote control using your Arduino clone board. We will use a solderless breadboard. These are really useful, and provide a fast, and very easy way to put circuits together without needing to solder.\r\n* Target practice is available all over the world after the workshop.\r\n \r\n**Registration**: \r\nBuy a kit at the Hardware Hacking Area to guarantee a seat, or come by early!

"description": "# Build Your Own Air Quality Sensor\r\n\r\nAir pollution affects many people’s daily lives, not only those living near industrial centres. In Ireland, official air quality monitoring relies on a limited number of sensors, so local and short-term pollution sources can be missed. In this 90-minute, hands-on workshop, you’ll build your own particulate matter (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.\r\n\r\n## Sensor.Community\r\n[Sensor.Community](https://sensor.community/) is an open, global 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 locations.\r\n\r\n## What You’ll Learn\r\nDuring the workshop, you’ll assemble a working PM2.5 air quality sensor and get it online. We’ll cover the basics 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.\r\n\r\n## Materials\r\nYou’ll work with:\r\n- ESP8266 board\r\n- SDS011 particulate matter sensor (PM2.5 and PM10)\r\n- BME280 sensor (temperature, humidity, air pressure)\r\n- USB cable\r\n- Jumper wires\r\n- Plastic tube (air inlet)\r\n\r\n## Requirements\r\n- A device with a web browser and WiFi, such as a phone or laptop\r\n- All setup is browser-based, no software install needed\r\n- No previous experience required, beginner-friendly\r\n\r\n## Materials Costs\r\nIt costs **€60** for a kit to take home.\r\n\r\n## Instructions\r\n[Slides](https://docs.google.com/presentation/d/1H4KuVn2qhhqdg9caCRLc4V6N_QEV1xoevmVM4edoR44/edit?usp=sharing)\r\n\r\n## Facilitator\r\nTaught by [Jeffrey Roe](https://chaos.social/@tdr112).\r\n\r\n**Buy a kit at the Hardware Hacking Area to guarantee a seat, or come by early.

"description": "After three days of conference and talks, what better ways to wind out the day than to get together in a relaxed atmosphere and try to build some hardware?\r\n\r\nThis workshop is intended for beginners who want to learn how to build their own lora/meshtastic/meshcore/reticulum hardware. 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 software 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\" manual. There will be little to no input 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 stay until you are done or finish in on your own time.\r\n\r\nEach node will consist of a solar panel, a low power lora node (XIAO nRF52840 & Wio-SX1262 Kit), 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 components we found, for long term use you might want to upgrade some components.\r\n\r\nThere will be only a limited amount of seats available. Please come to the hardware hacking area one hour (22:00) before this workshop starts to get the hardware (35€, cash preferred). This workshop is intended for beginners in Lora hardware and hardware hacking. Some previous soldering experience is helpful but not required.\r\n\r\nHow to guide: https://cryptpad.fr/code/#/2/code/view/u1VaqnWs0jvLT6qRDUipwyGw4G4xOmyqymF20y4gLvc/embed/present/",

"description": "**Learn to solder** by making a way-cool, powerful music synthesizer, and \r\n**learn how to make cool music, sound, (and noise!) with computer chips** \r\n(The fancy word for making sound with a computer chip is *Digital Signal Processing* or *DSP*). \r\n \r\n**[ArduTouch](https://cornfieldelectronics.com/cfe/projects.php#ardutouch)** is an open hardware **Ardu**ino-compatible music synthesizer kit with a built-in **Touch** Keyboard, and with built-in speaker/amplifier. It is a really nice performing musical instrument. \r\n \r\nThis workshop is for **total newbies** to learn to solder. \r\nThis workshop is for **total newbies** to make their own ArduTouch music synthesizer and learn to make music, sound (and noise!) with computer chips. Attendees take their completed synthesizer home at the end of the workshop. \r\n \r\nThe ArduTouch comes pre-programmed with a way cool synthesizer. And I will show you how to re-program it with other way cool (and totally different) synthesizers, and how to make your own synthesizers. \r\n \r\nFor ages 10 - 100. \r\n \r\n**Materials costs**: \r\nThe workshop is free, but if you would like to partake in the hands-on aspects of the workshop, Mitch will have ArduTouch kits for **€35**. \r\n*Optional*: USB-Serial Cable for re-programming ArduTouch (and many other projects): **5 €**. \r\n \r\n**Taught by** [Mitch Altman](http://en.wikipedia.org/wiki/Mitch_Altman). \r\n \r\n_**Optional**: Bring your laptop if you want to go home with the free Arduino software installed on it. \r\nArduino software runs on Windows, MacOS and Linux._ \r\n \r\n**Workshop Itinerary**: \r\n* Intro to music synthesis\r\n* Basics of making sound with computer chips (Digital Signal Processing)\r\n* Basics of using an Arduino\r\n* Learn to solder. Don't let this scare you! I've taught tens of thousands 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 useful.\r\n* How to re-program your ArduTouch music synthesizer to make lots of cool music, sounds, (and noise!)\r\n \r\n**Registration**: \r\n**Buy a kit at the Hardware Hacking Area to guarantee a seat, or come by early!

No prior knowledge of reflow soldering is required, but a steady hand (go easy on caffeine!) and good eyes are useful. \r\n\r\n**The steps we'll go through are:**\r\n1. Apply solder paste to the front board with a stencil\r\n2. Place the 144 LEDs on the board one-by-one, using tweezers (this can easily take a couple of hours)\r\n3. Solder the LEDs on a hot plate\r\n4. Apply solder paste to the back of the board with another stencil\r\n5. Place the microcontroller, capacitors, resistors and other components on the board one-by-one\r\n6. Solder the components with a hot air\r\n7. Repeat the same steps for the 2nd board (with far fewer components on it)\r\n8. Test and debug the boards (this can take until after midnight if there are many problematic boards)\r\n \r\n## Registration\r\nTo register for this workshop, please buy a kit at the [BlinkenArea](assembly://blinkenarea) assembly *as early as possible*.

Check out the PDF build guide here: https://github.com/fablabnk/TriggWorkshop/blob/main/TriggBuildGuide.pdf\r\n\r\nTrigg is our version of the Hack Club Sprig, which we adapted into a through-hole soldering kit in the FabLab of our coding school 42 Berlin, to teach soldering and basic electronics to coding students. Kits include a Raspberry Pi Pico (RP2040) and all components (batteries and USB cable not included).\r\n\r\nOur workshop and build guide will take you from the basics of soldering through to assembling, soldering, flashing and testing your Trigg, increasing your confidence as you go. After building, come by to our assembly to code and flash your first game. Parent-child building teams are also very welcome. \r\n\r\n**Registration**: \r\nBuy a kit at the Hardware Hacking Area to guarantee a seat, or come by early!
