Bored of talks? Burnt out on pixels? Swing by and solder.

Participants can assemble and program their very own blinky PCB — a tiny circuit that flashes their name in Morse Code. Whether you're new to electronics or just need a break from abstract systems talk, this project hits the sweet spot: tactile, nerdy, and unique. And yes, you get to take it home.

Depending on your experience, you will find yourself spending about ~30min with us for soldering and flashing pre-made code. In case you want to dig deeper into the programming part and create your own blink code and customize it, feel invited to stay a little longer.

+++IMPORTANT NOTICE+++

Due to logistical restrictions, the number of soldering irons is _very_ limited at our session. If you can and have a soldering iron available, please take it with you. You might also ask around your village or nearby neighbors to borrow one, many hackers carry small USB or DC powered irons with them. Thank you for your understanding! All other materials are available in sufficient amounts.

* [0 People have this question/issue] Add your question/issue here or increase the number.
* [1 People have this question/issue] After reflash and exiting the intial sponsors screen, the screen stays blue.
* [4 People have this question/issue] screen is not turning on at all.
* [2 People have this question/issue] Can not turn off badge while charging.
* [1] How do I reset the badge on battery?
** => Applying usb power will reset the badge
* [1 People have this question/issue] The antenna isn't connected yet. Can I use the device without damaging anything?
* [2 People have this question/issue] Batteries ar being held firmly (maybe a bit too firmly) in place in the battery holder. How can I safely remove the batteries? What tool to use for this without damaging the batteries or the PCB?
* [1] One battery holder has a big blob of epoxy where it should contact the battery. Is there a good way to remove it?
* [3 People have this question/issue] The badge suddenly stopped working. (possibly coincides with first time plugging in USB-C and charging my own protected cells). Removing Batteries did not help. Re-Flashing with newest firmware did not help.
** => Reseating the ESP daughterboard (fitted with a screw) helped here.

* [4 People have this question/issue] OTA update screen appears on first boot, after pressing space bar, blue screen with nothing happening for over an hour.
** Have the same problem after first OTA update. Update started but the device stuck on bluescreen for an hour or so before I removed power. After flashing a new firmware using the [https://why-prog.heplaphon.com web updater] it works again (use the USB slot on the side, otherwise you get an error message "Your ESP C6 chip is unsupported"). [https://pastebin.com/VjMA5ZZA Logfiles] --[[User:Cybso|Cybso]] ([[User talk:Cybso|talk]]) 00:03, 11 August 2025 (CEST)
*** No, it doesn't. It displayed the sponsors page once but returned to the bluescreen afterwards. [https://pastebin.com/cCKejKCk Logs from the side USB port]. --[[User:Cybso|Cybso]] ([[User talk:Cybso|talk]]) 00:18, 11 August 2025 (CEST)
*** Uploaded another log containing the complete first boot after flashing the new firmware: https://pastebin.com/3NiSRncL (edit: see below). Note the exception at the end: "Task 4 caused an unhandled exception, Cerberos will deal with it". After that, no new entries appear and the display stays blue. --[[User:Cybso|Cybso]] ([[User talk:Cybso|talk]]) 00:25, 11 August 2025 (CEST)
*** Was wrong about that again. There were more log entries while I wrote the previous comments. Here is the complete log: https://pastebin.com/KMQwhBPv --[[User:Cybso|Cybso]] ([[User talk:Cybso|talk]]) 00:34, 11 August 2025 (CEST)
* [7 People have this question/issue] Blue screen. Nothing happening.
* [5 People have this issue] WHY2025 OTA updater is not reacting.
** => We are working on this. For now, don't touch it and instead just wait at least 30 seconds.
* [3 People have this question/issue] There is a stripe in my screen.
** There is a protective cellophane sheet attached to the screen for protection against scratches and dirt. Remove the cellophane sheet by peeling it off. Start in the lower right corner. There should be some sticky tape area of 8x8mm you can use to start peeling it off.
*** I saw at least one device where the sticky tape area was '''under''' the front cover. --[[User:Cybso|Cybso]] ([[User talk:Cybso|talk]]) 00:03, 11 August 2025 (CEST)
* [2 People have this question/issue] There is a stamp HD3 in my screen.

* [2 People have this question/issue] Could do one update, then three updates and then BadgeVMS Firmware Version 4. Now I a offered this update on every boot and can do nothing else, even though I have installed it already
** reboot fixes this.
* [3 People have this question/issue] My Badge is showing a yellow screen. Its starting with a blue screen and shows the Menu for a few seconds an then turns yellow. What does this indicate?
* [1 Person has this question/issue] Cannot build the firmware from https://gitlab.com/why2025/team-badge/firmware/. Tried to build main and flashed_at_first_handout - both fail because of the following error: https://pastebin.com/H4xwPLhC

** => Install this driver: https://www.wch.cn/downloads/CH34XSER_MAC_ZIP.html
*** Make sure to carefully follow the instructions, a 3rd party kernel extension is needed and restart might be needed as well.
*** '''Don't''' use brew, it has been reported not to work.
* [1 People have this question/issue] After installing OTA update, application updates AND System Update "BadgeVMS Firmware, Version 4, Main Badge Firmware" the system restarts showing System Updates => "Updates available 1" => "BadgeVMS Firmware, Version 4, Main Badge Firmware". Selecting it, installing it and autorstarting leads back to this same screen. I seem to be stuck in a loop of the update process.
** => Shut down your badge by double tapping the power button. Restart. You should now see the application WHY Application Launcher.
* [1 Person has this issue] I can't flash the badge - it says the board is incompatible
** => Use the USB-C port on the side of the board, not the one on the bottom

Bored of talks? Burnt out on pixels? Swing by and solder.

Participants can assemble and program their very own blinky PCB — a tiny circuit that flashes their name in Morse Code. Whether you're new to electronics or just need a break from abstract systems talk, this project hits the sweet spot: tactile, nerdy, and unique. And yes, you get to take it home.

Depending on your experience, you will find yourself spending about ~30min with us for soldering and flashing pre-made code. In case you want to dig deeper into the programming part and create your own blink code and customize it, feel invited to stay a little longer.

+++IMPORTANT NOTICE+++

Due to logistical restrictions, the number of soldering irons is _very_ limited at our session. If you can and have a soldering iron available, please take it with you. You might also ask around your village or nearby neighbors to borrow one, many hackers carry small USB or DC powered irons with them. Thank you for your understanding! All other materials are available in sufficient amounts.

== About ==
We are a Network of People who do some more or less creative projects to supply the digital community with new mindsets. While keeping balance between art and science we never forget the fun. The name Frubar is a mixture of foo bar and the german word for copious (fruchtbar). We thought it would describe best what we are doing. ;-)

== Contact ==

For the upcoming event the most stuff is discussed in [https://matrix.to/#/#FrubarVillage:palimpal.im Matrix]. Please get in touch to be added to the list of members.

Some are also available via IRC:
