DESCRIPTION:In this no-code session\, you'll learn how to personalize your
  LED badge using the open source Badge Magic mobile app\, available for bo
 th Android and iOS. Create your own scrolling messages\, icons\, patterns\
 , and fun display effects — all without writing a single line of code. J
 ust open the app\, connect your badge\, and start designing.\n\nThis sessi
 on is beginner-friendly and open to everyone. Experiment with different st
 yles\, share ideas\, and learn together with others at the table. Perfect 
 for newcomers\, makers\, and anyone who wants to have fun customizing thei
 r badge.\n\n**What You’ll Need**\n- Your LED badge (available for purcha
 se at the assembly)\n- An Android or iOS device with the Badge Magic app i
 nstalled\n- A data-capable USB cable or Bluetooth connection (depending on
  badge type)\n\n**What You’ll Do**\n- Connect your LED badge to your pho
 ne\n- Create text messages with fonts\, speed\, brightness\, and effects\n
 - Add icons\, patterns\, and simple animations

DESCRIPTION:The goal of this workshop is to enable participants to update 
 the firmware of their PSLab device.\nThe firmware of the Pockes Science La
 b is constantly being developed and improved. To benefit from this\, the u
 pdates must be flashed onto the PSLab board. This process is quick and eas
 y\, but can be a little daunting if you have never done it before. In this
  workshop\, we will take a look at the tools and hardware required and car
 ry out the process together.\n\nIf you don't want to update the firmware o
 n your device yourself\, but just want to have the latest firmware install
 ed on your board\, you are also welcome to join us.\nYou will need:\n* You
 r PSLab board (v5 or v6)\, available for borrowing or purchase during the 
 workshop\n* A computer\n* A USB cable to connect the board to your compute
 r\n* Ideally\, a PICKit 3 programmer (v5 only\, at least one will be avail
 able)\n\nThis workshop is led by Marc Nause\, contributor of Pocket Scienc
 e Lab project. Marc has experience with the flash process on Linux and Win
 dows. With macOS and other operating systems we may need to research toget
 her how the process works best
