 o-for-total-newbies-workshop\n\nDescription:\n**[Arduino](http://arduino.c
 c/)** is an amazingly powerful tool that is very simple to learn to use. I
 t 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 e
 nough so that experienced expert geeks can use it for their projects as we
 ll.\n\nThis workshop is easy enough for _**total newbies**_ to **learn all
  you need to know to get going on an Arduino.**\n\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 T
 Vs in public places -- a fun way to learn Arduino (and electronics) basics
 .\n\n**Materials costs**:  \nThe workshop is free\, but if you would like 
 to partake in the hands-on aspects of the workshop\, Mitch will have mater
 ials for **€40** (useful for making many different cool projects).\n\n**
 Taught by** [Mitch Altman](http://en.wikipedia.org/wiki/Mitch_Altman).\n\n
 _**Optional**:  Bring your laptop if you want to go home with the free Ard
 uino software installed on it.  \nArduino software runs on Windows\, MacOS
  and Linux._\n\n**Workshop page:**  \n[Arduino For Total Newbies workshop 
 page](http://cornfieldelectronics.com/cfe/projects/tvbg_arduino/tvbg_ardui

 ort lesson to learn everything you need to know about electronics!\n* Then
  we will learn to solder. Don't let this scare you! I've taught tens of th
 ousands 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 ver
 y useful.\n* Then we will each make our own Arduino clone from a kit.\n* N
 ow that we each have our own Arduino board\, we will set up the free and o
 pen-source *Arduino software* on our laptops (if you bring one) -- Windows
 \, Linux\, 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 read schematic diagrams\, and you'll put together your own TV-B-Gone re
 mote control using your Arduino clone board. We will use a solderless brea
 dboard. These are really useful\, and provide a fast\, and very easy way t
 o put circuits together without needing to solder.\n* Target practice is a
 vailable all over the world after the workshop.\n\n**Registration**:  \nBu

 Sensor\n\nAir pollution affects many people’s daily lives\, not only tho
 se living near industrial centres. In Ireland\, official air quality monit
 oring relies on a limited number of sensors\, so local and short-term poll
 ution 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 v
 iew and share the data.\n\n## Sensor.Community\n[Sensor.Community](https:/
 /sensor.community/) is an open\, global citizen science network where peop
 le build low-cost sensors and share environmental data. Once your device i
 s online\, it can publish readings so you can track trends over time and c
 ompare data across different locations.\n\n## What You’ll Learn\nDuring 
 the workshop\, you’ll assemble a working PM2.5 air quality sensor and ge
 t it online. We’ll cover the basics of IoT devices\, local data collecti
 on\, 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- SDS01
 1 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\, su
 ch as a phone or laptop\n- All setup is browser-based\, no software instal

 orer Badge Soldering Workshop\n\nIn this hands-on build-and-explore worksh
 op\, participants assemble their own **[EMF Explorer Badge](https://emfexp
 lorer.space)** using guided soldering instruction\, learn the science of e
 lectromagnetic frequency bands\, and plug in headphones to *listen* to the
  invisible world around them. Every participant takes home their own explo
 ration kit: badge + headphones\, ready for EMF exploring with an illuminat
 ed badge that can be used at night for visibility and bling.\n\n---\n\n###
 ## Material Costs\n€20 - €30\n\n---\n\n##### Workshop Itinerary\n- **W
 elcome + Electronics and Soldering Info** We will show you how to solder. 
 Anyone who can safely hold a soldering iron can do it! It is actually a ve
 ry easy skill to learn. It is also very useful.\n- **EMF Explanation and B
 adge Creation Overview** Learn about what EMF is\, where it comes from\, a
 nd how the badge works.\n- **Badge Assembly** Get to soldering! We will be
  available to help you along the way.\n- **Check your work\, and power up 
 your badge!**\n- **Wrap-Up + Q&A**\n- **Live Exploration!** You are surrou
 nded by interesting electronics at 39C3. Go exploring! What new sounds do 
 you hear? Some of the most unassuming electronics can make the most intere
 sting sounds.\n\n---\n\n##### Registration Info\nBuy a kit at the Hardware
  Hacking Area to guarantee a seat\, or come by early! (And please do arriv
 e early\, regardless!) First-come\, first-served.\n- **Age:** anyone who c
 an safely hold a soldering iron\n- **Experience level:** No prior solderin
 g experience required\n- **Take-home:** Your assembled badge + headphones 
 included\n\n---\n\n##### Links\n[EmfExplorer.Space](https://emfexplorer.sp
 ace)\n\n---\n\n##### Instructor Notes\nThis is a **beginner-first hardware
  workshop**. The goal is skill building\, curiosity\, and real-world elect
 ronics exploration. The badge is both a tool and a conversation piece: it 
 senses EMF\, plays it through audio\, and glows for visibility and bling.

 unt Electronics Assembly for Terrified Beginners**\n\nIn this workshop\, w
 e will learn to handle the tiniest electronic components\, which are used 
 to make modern electronic devices. We will cheat the same way the electron
 ics industry does\, and learn the techniques of stencil paste printing and
  reflow soldering. You will learn a technique that stops your hands from s
 haking\, so you can very very precisely place microscopic parts. We will m
 ake an electronic cat that purrs if you handle it correctly. No prior expe
 rience or knowledge of anything electronic needed. Caffeine use is not rec
 ommended immediately before. All tools are provided.  Takes around 2 hours
 .\n\n**Materials costs**:  \n20€ if you want to make a board\, free to o
 bserve.\n\n**Taught by** Kliment.\n\n**Workshop Itinerary**:\n\n**Registra

 our-own-brain-machine\n\nDescription:\nWhat is a **[Brain Machine](https:/
 /cornfieldelectronics.com/cfe/projects.php#brainmachine)**? It's a fascina
 ting device that generates light and sound pulses at brainwave frequencies
 . These can help achieve various states of consciousness\, such as meditat
 ion or improved sleep.\n\nIn this workshop for **total beginners** we will
  all make a **[Brain Machine](https://cornfieldelectronics.com/cfe/project
 s.php#brainmachine)** that is preprogrammed with a really nice meditation 
 sequence. As well as a device that can help you relax and meditate\, a nic
 e bonus is that everyone hallucinates beautiful colors and patterns along 
 the way.\n\nThe Brain Machine is totally [open hardware](https://github.co
 m/maltman23/Brain_Machine_kit)\, and created to be hackable\, so you can r
 e-program it with any computer\, with software that is free to download an
 d use.\n\nThis workshop is for **total beginners** to learn to solder.\n\n
 For ages 10 - 100.\n\n**Materials costs**:  \nThe workshop is free\, but i
 f you would like to partake in the hands-on aspects of the workshop\, Mitc
 h will have Brain Machine kits for **€25**.\n\n**Taught by** [Mitch Altm
 an](http://en.wikipedia.org/wiki/Mitch_Altman).\n\n_**Optional**:  Bring y
 our laptop if you want to go home with the free Arduino software installed
  on it.  \nArduino software runs on Windows\, MacOS and Linux._\n\n_**IMPO
 RTANT NOTE:** The Brain Machine uses blinking lights\, and is not recommen
 ded for people who are photosensitive._\n\n**Workshop Itinerary**:\n* Intr
 o to Sound & Light Machines\n* Learn to solder. Don't let this scare you! 
 I've taught tens of thousands of people to solder\, most of whom have neve
 r made anything before in their lives. It is actually a very easy skill to
  learn. It is also very useful.\n* How to re-program your Brain Machine fo
 r creating other brainwave sequences\n\n**Registration**:  \nBuy a kit at 
 the Hardware Hacking Area to guarantee a seat\, or come by early! (And ple
 ase do arrive early\, regardless!) First come\, first served.\n\n**Links**
