== Signal Group ==
Yes, we have a dedicated '''WHY2025 Badge Updates''' Signal group.

https://signal.group/#CjQKINdiQ_2mg4ZIZ9AbjD5UHq8gnIgRojSTnOb6lbx-Tvh_EhDHBzcPicIer3NabcN0fuR9

== Batteries ==

* Beware of the [[Badge/Fire hazard]] warning before you use batteries in the device.
* insert Cell Positive (+) side, which is the 'middle' of the badge, first, and Cell Minus (-), near the 'edge' of the badge, second.
* don't forget to take it out when not in use because of https://why2025.org/post/822
* you can flash with the batteries in, for charging you can use any of the two ports

== Badge Case Info ==

Currently cases are designed around the prototype PCBs. The final boards might be slightly different, so best advise is currently to wait until (after) the camp with printing one - the badges will be usable without a case. Instead, maybe help with printing the 3mm full-frame spaces (see above).

• Designing your own case? Use the existing screw holes on the badge.
• Bring M2 screws, up to 15 mm in length depending on your case design.
• Badges function fully without a case.
• Note: Cases take much longer to print than spacers.

Case Examples by the community:
 
* [https://www.printables.com/model/1372316-why2025-badge-case Semi-official case]
* [https://www.printables.com/model/1376706-why-2025-badge-case-remix Remix of above for printing without supports]
* [https://www.printables.com/model/1377822-why2025-transparent-case Other case design which allows for transparent cases]
* [https://momakemore.com/micropages/why2025/ Another feature rich heavy duty case by @MoMakeMore based on the cutouts by @Dynom]
* [https://www.printables.com/model/1380554-why2025-badge-case-speedy-print-the-boat-hull Speedy Print Case by @MattGrayYes], which can print in under an hour on a Prusa MK4

== Installing apps from BadgeHub via microSD Card ==
You need a microSD card for this.

# 1. Create the folder stucture ./BADGEVMS/APPS on there.
# 2. In the APPS folder, create a folder named like the badge hub project name.
# 3. Download the app from [https://badge.why2025.org/ BadgeHub] and put the .elf in there.
# 4. Create a json file with the project name next to the folder
# 5. Put the key/values for name, unique_identifier, version and binary_path (full name of the .elf file) in that json file.

== ⚠️ Update! State of "Not assembled" Badges ==
For the badges that were handed out in an unassembled state, please make sure to follow this guide for assembly:

2 variants spacers were added to the white bags that were handed out with your badge:
* 1 variant has a fully printed frame with holes on each corner.
** This one needs to be placed between the badge carrier PCB and the front plate and will cover all electronics on the side.

* the other variant has (at least) 4 small black plastic cilinders. The cilinders look like the following:

[[File:Badge with small spacers.jpg|300px|alt=Badge with small spacers]]

Please make sure to install them between the badge and the front plate like this:

[[File:Spacers on badge.jpg|300px|alt=spacers on badge]]
[[File:Screenshot 2025-08-12 at 20.03.55.png|300px|alt=Badge with small spacer installed and front plate screwed.]]

You have installed these correctly if you can see a clear gap between the badge carrier PCB and the front plate like in the picture above.

== Badge Assembly at BadgeTent ==

We aim to conduct the full-scale assembly during the whole day of Friday, which will involve a maximum of 30 volunteers working in the 15*15 meters BadgeTent.

Assembly involves screwing everything together.

Assembling your first '''WHY2025''' badge might feel overwhelming, that’s okay.

Take your time, explore the parts, and build confidence.

With repetition:
* 1st time = You're learning. -> Instructions on how to handle the components will be provided.
* 5th time = You gain confidence by knowing your tools and how to grab them the best way.
* 500th time = Congratulations, you have accomplished the assembly and will have a Foxconn recruiter on the line.

Parts to assemble:
* CarrierBoard
* Keyboard Dome Layer
* Keyboard Silicon Layer
* 3mm Spacers
* 4x M2 Screws
* Front Panel PCB

If you want to help out in the Badge Assembly on Friday during the day -> then join this Signal group.

[https://signal.group/#CjQKIIORCgY9yjX3a834iz-RQeOQu80fIZtg-i3G56EYqnaQEhBaRn9aHmtLggM6oH7dWXC5 Badge Assembly - Signal group].

=== Lessons Learned during Badge Assembly ===

We encountered a small number of badges (three in total) where the Keyboard Dome Layer was slightly misaligned, leading to a few non-responsive keys. Thanks to our initial test-flashing process, we were able to detect these issues early and have since improved our application method for the Dome Layer.

To ensure quality, every badge will undergo a final quality control check, including a visual inspection of the epoxy and final firmware flashing, so that everyone receives a fully functional badge.

== LoRa Details ==

• The LoRa connector will not be pre-soldered but will be handed out as a compontent separately.
• You’ll also receive a screw-on LoRa antenna.

== SAO's ==

It's likely that you'll need to install the serial driver on a Mac before you can flash the board via USB Serial.

''Without the driver, the USB Serial device shows up in System Information, but there is no TTY for it.''

As tested on Mac OS Sequoia 15.4:

# Download the [https://www.wch.cn/downloads/CH34XSER_MAC_ZIP.html Serial Driver] (the blue button labelled 下载)
## Beware the PDF instructions miss a step that is required in Mac OS 15.4
# Open the ZIP file
# Open the DMG file
# Drag the app into Applications
# Run the app
# Click ''Install''
# Go to ''System Settings -> General'' and scroll to the Extensions section at the bottom
# Click the ⓘ symbol next to ''Driver Extensions''
# enable "cn.wch.CH34xVCPDriver"

After this, there should now be a TTY available to communicate with the badge.

You can test this in terminal with
<pre>ls /dev/tty.*</pre>
and you should see <pre>/dev/tty.wchusbserial10</pre> in the list.

<hr>

The badge should now appear as ''USB Serial (wchusbserial10)'' or similar on the [https://why-prog.heplaphon.com/ WHY Badge Web Flasher].

== Installing apps from BadgeHub via microSD Card ==
You need a microSD card for this.

# 1. Create the folder stucture ./BADGEVMS/APPS on there.
# 2. In the APPS folder, create a folder named like the badge hub project name.
# 3. Download the app from [https://badge.why2025.org/ BadgeHub] and put the .elf in there.
# 4. Create a json file with the project name next to the folder
# 5. Put the key/values for name, unique_identifier, version and binary_path (full name of the .elf file) in that json file.

== ⚠️ Update! State of "Not assembled" Badges ==
For the badges that were handed out in an unassembled state, please make sure to follow this guide for assembly:

2 variants spacers were added to the white bags that were handed out with your badge:
* 1 variant has a fully printed frame with holes on each corner.
** This one needs to be placed between the badge carrier PCB and the front plate and will cover all electronics on the side.

* the other variant has (at least) 4 small black plastic cilinders. The cilinders look like the following:

[[File:Badge with small spacers.jpg|300px|alt=Badge with small spacers]]

Please make sure to install them between the badge and the front plate like this:

[[File:Spacers on badge.jpg|300px|alt=spacers on badge]]
[[File:Screenshot 2025-08-12 at 20.03.55.png|300px|alt=Badge with small spacer installed and front plate screwed.]]

You have installed these correctly if you can see a clear gap between the badge carrier PCB and the front plate like in the picture above.

We aim to conduct the full-scale assembly during the whole day of Friday, which will involve a maximum of 30 volunteers working in the 15*15 meters BadgeTent.

Assembly involves screwing everything together.

Assembling your first '''WHY2025''' badge might feel overwhelming, that’s okay.

Take your time, explore the parts, and build confidence.

With repetition:
* 1st time = You're learning. -> Instructions on how to handle the components will be provided.
* 5th time = You gain confidence by knowing your tools and how to grab them the best way.
* 500th time = Congratulations, you have accomplished the assembly and will have a Foxconn recruiter on the line.

Parts to assemble:
* CarrierBoard
* Keyboard Dome Layer
* Keyboard Silicon Layer
* 3mm Spacers
* 4x M2 Screws
* Front Panel PCB

If you want to help out in the Badge Assembly on Friday during the day -> then join this Signal group.

=== Lessons Learned during Badge Assembly ===

We encountered a small number of badges (three in total) where the Keyboard Dome Layer was slightly misaligned, leading to a few non-responsive keys. Thanks to our initial test-flashing process, we were able to detect these issues early and have since improved our application method for the Dome Layer.

To ensure quality, every badge will undergo a final quality control check, including a visual inspection of the epoxy and final firmware flashing, so that everyone receives a fully functional badge.

== LoRa Details ==

• The LoRa connector will not be pre-soldered but will be handed out as a compontent separately.
• You’ll also receive a screw-on LoRa antenna.

== SAO's ==

== Signal Group ==
Yes, we have a dedicated '''WHY2025 Badge Updates''' Signal group.

https://signal.group/#CjQKINdiQ_2mg4ZIZ9AbjD5UHq8gnIgRojSTnOb6lbx-Tvh_EhDHBzcPicIer3NabcN0fuR9

== Batteries ==

* Beware of the [[Badge/Fire hazard]] warning before you use batteries in the device.
* insert Cell Positive (+) side, which is the 'middle' of the badge, first, and Cell Minus (-), near the 'edge' of the badge, second.
* don't forget to take it out when not in use because of https://why2025.org/post/822
* you can flash with the batteries in, for charging you can use any of the two ports

== Badge Case Info ==

Currently cases are designed around the prototype PCBs. The final boards might be slightly different, so best advise is currently to wait until (after) the camp with printing one - the badges will be usable without a case. Instead, maybe help with printing the 3mm full-frame spaces (see above).

• Designing your own case? Use the existing screw holes on the badge.
• Bring M2 screws, up to 15 mm in length depending on your case design.
• Badges function fully without a case.
• Note: Cases take much longer to print than spacers.

Case Examples by the community:
 
* [https://www.printables.com/model/1372316-why2025-badge-case Semi-official case]
* [https://www.printables.com/model/1376706-why-2025-badge-case-remix Remix of above for printing without supports]
* [https://www.printables.com/model/1377822-why2025-transparent-case Other case design which allows for transparent cases]
* [https://momakemore.com/micropages/why2025/ Another feature rich heavy duty case by @MoMakeMore based on the cutouts by @Dynom]
* [https://www.printables.com/model/1380554-why2025-badge-case-speedy-print-the-boat-hull Speedy Print Case by @MattGrayYes], which can print in under an hour on a Prusa MK4

== Installing apps from BadgeHub ==
You need a microSD card for this.

# 1. Create the folder stucture ./BADGEVMS/APPS on there.
# 2. In the APPS folder, create a folder named like the badge hub project name.
# 3. Download the app from [https://badge.why2025.org/ BadgeHub] and put the .elf in there.
# 4. Create a json file with the project name next to the folder
# 5. Put the key/values for name, unique_identifier, version and binary_path (full name of the .elf file) in that json file.

== ⚠️ Update! State of "Not assembled" Badges ==
For the badges that were handed out in an unassembled state, please make sure to follow this guide for assembly:

2 variants spacers were added to the white bags that were handed out with your badge:
* 1 variant has a fully printed frame with holes on each corner.
** This one needs to be placed between the badge carrier PCB and the front plate and will cover all electronics on the side.

* the other variant has (at least) 4 small black plastic cilinders. The cilinders look like the following:

[[File:Badge with small spacers.jpg|300px|alt=Badge with small spacers]]

Please make sure to install them between the badge and the front plate like this:

[[File:Spacers on badge.jpg|300px|alt=spacers on badge]]
[[File:Screenshot 2025-08-12 at 20.03.55.png|300px|alt=Badge with small spacer installed and front plate screwed.]]

You have installed these correctly if you can see a clear gap between the badge carrier PCB and the front plate like in the picture above.

== Badge Assembly at BadgeTent ==

We aim to conduct the full-scale assembly during the whole day of Friday, which will involve a maximum of 30 volunteers working in the 15*15 meters BadgeTent.

Assembly involves screwing everything together.

Assembling your first '''WHY2025''' badge might feel overwhelming, that’s okay.

Take your time, explore the parts, and build confidence.

With repetition:
* 1st time = You're learning. -> Instructions on how to handle the components will be provided.
* 5th time = You gain confidence by knowing your tools and how to grab them the best way.
* 500th time = Congratulations, you have accomplished the assembly and will have a Foxconn recruiter on the line.

Parts to assemble:
* CarrierBoard
* Keyboard Dome Layer
* Keyboard Silicon Layer
* 3mm Spacers
* 4x M2 Screws
* Front Panel PCB

If you want to help out in the Badge Assembly on Friday during the day -> then join this Signal group.

=== Lessons Learned during Badge Assembly ===

We encountered a small number of badges (three in total) where the Keyboard Dome Layer was slightly misaligned, leading to a few non-responsive keys. Thanks to our initial test-flashing process, we were able to detect these issues early and have since improved our application method for the Dome Layer.

To ensure quality, every badge will undergo a final quality control check, including a visual inspection of the epoxy and final firmware flashing, so that everyone receives a fully functional badge.

== Signal Group ==
Yes, we have a dedicated '''WHY2025 Badge Updates''' Signal group.

https://signal.group/#CjQKINdiQ_2mg4ZIZ9AbjD5UHq8gnIgRojSTnOb6lbx-Tvh_EhDHBzcPicIer3NabcN0fuR9

== Batteries ==

* Beware of the [[Badge/Fire hazard]] warning before you use batteries in the device.
* insert Cell Positive (+) side, which is the 'middle' of the badge, first, and Cell Minus (-), near the 'edge' of the badge, second.
* don't forget to take it out when not in use because of https://why2025.org/post/822
* you can flash with the batteries in, for charging you can use any of the two ports

== Badge Case Info ==

Currently cases are designed around the prototype PCBs. The final boards might be slightly different, so best advise is currently to wait until (after) the camp with printing one - the badges will be usable without a case. Instead, maybe help with printing the 3mm full-frame spaces (see above).

• Designing your own case? Use the existing screw holes on the badge.
• Bring M2 screws, up to 15 mm in length depending on your case design.
• Badges function fully without a case.
• Note: Cases take much longer to print than spacers.

Case Examples by the community:
 
* [https://www.printables.com/model/1372316-why2025-badge-case Semi-official case]
* [https://www.printables.com/model/1376706-why-2025-badge-case-remix Remix of above for printing without supports]
* [https://www.printables.com/model/1377822-why2025-transparent-case Other case design which allows for transparent cases]
* [https://momakemore.com/micropages/why2025/ Another feature rich heavy duty case by @MoMakeMore based on the cutouts by @Dynom]
* [https://www.printables.com/model/1380554-why2025-badge-case-speedy-print-the-boat-hull Speedy Print Case by @MattGrayYes], which can print in under an hour on a Prusa MK4

== ⚠️ Update! State of "Not assembled" Badges ==
For the badges that were handed out in an unassembled state, please make sure to follow this guide for assembly:

2 variants spacers were added to the white bags that were handed out with your badge:
* 1 variant has a fully printed frame with holes on each corner.
** This one needs to be placed between the badge carrier PCB and the front plate and will cover all electronics on the side.

* the other variant has (at least) 4 small black plastic cilinders. The cilinders look like the following:

[[File:Badge with small spacers.jpg|300px|alt=Badge with small spacers]]

Please make sure to install them between the badge and the front plate like this:

[[File:Spacers on badge.jpg|300px|alt=spacers on badge]]
[[File:Screenshot 2025-08-12 at 20.03.55.png|300px|alt=Badge with small spacer installed and front plate screwed.]]

You have installed these correctly if you can see a clear gap between the badge carrier PCB and the front plate like in the picture above.

== Badge Assembly at BadgeTent ==

We aim to conduct the full-scale assembly during the whole day of Friday, which will involve a maximum of 30 volunteers working in the 15*15 meters BadgeTent.

Assembly involves screwing everything together.

Assembling your first '''WHY2025''' badge might feel overwhelming, that’s okay.

Take your time, explore the parts, and build confidence.

With repetition:
* 1st time = You're learning. -> Instructions on how to handle the components will be provided.
* 5th time = You gain confidence by knowing your tools and how to grab them the best way.
* 500th time = Congratulations, you have accomplished the assembly and will have a Foxconn recruiter on the line.

Parts to assemble:
* CarrierBoard
* Keyboard Dome Layer
* Keyboard Silicon Layer
* 3mm Spacers
* 4x M2 Screws
* Front Panel PCB

If you want to help out in the Badge Assembly on Friday during the day -> then join this Signal group.

[https://signal.group/#CjQKIIORCgY9yjX3a834iz-RQeOQu80fIZtg-i3G56EYqnaQEhBaRn9aHmtLggM6oH7dWXC5 Badge Assembly - Signal group].

=== Lessons Learned during Badge Assembly ===

We encountered a small number of badges (three in total) where the Keyboard Dome Layer was slightly misaligned, leading to a few non-responsive keys. Thanks to our initial test-flashing process, we were able to detect these issues early and have since improved our application method for the Dome Layer.

To ensure quality, every badge will undergo a final quality control check, including a visual inspection of the epoxy and final firmware flashing, so that everyone receives a fully functional badge.

== LoRa Details ==

• The LoRa connector will not be pre-soldered but will be handed out as a compontent separately.
• You’ll also receive a screw-on LoRa antenna.

== SAO's ==

Currently cases are designed around the prototype PCBs. The final boards might be slightly different, so best advise is currently to wait until (after) the camp with printing one - the badges will be usable without a case. Instead, maybe help with printing the 3mm full-frame spaces (see above).

• Designing your own case? Use the existing screw holes on the badge.

We aim to conduct the full-scale assembly during the whole day of Friday, which will involve a maximum of 30 volunteers working in the 15*15 meters BadgeTent.

Assembly involves screwing everything together.

Assembling your first '''WHY2025''' badge might feel overwhelming, that’s okay.

Take your time, explore the parts, and build confidence.

With repetition:
* 1st time = You're learning. -> Instructions on how to handle the components will be provided.
* 5th time = You gain confidence by knowing your tools and how to grab them the best way.
* 500th time = Congratulations, you have accomplished the assembly and will have a Foxconn recruiter on the line.

Parts to assemble:
* CarrierBoard
* Keyboard Dome Layer
* Keyboard Silicon Layer
* 3mm Spacers
* 4x M2 Screws
* Front Panel PCB

If you want to help out in the Badge Assembly on Friday during the day -> then join this Signal group.

What to bring

2025-08-06T06:03:20Z

LightEmittingDinosaur: Added sanitary products

== Things to bring ==
Continuous work in progress.

=== Camping equipment ===
*'''tent''' (You may want to bring a ''hammer'' to get those pegs into the ground)
*stable '''tent pegs''' (v-profile ones are best)
*'''sleeping bag'''
*'''mattress''' and '''sleeping pad''', maybe a '''cushion'''
*'''drinking bottle'''
Drink more water - drinking not enough (water! not mate, not beer!) is the most common DoS-Attack at camps.
*'''rescue blanket''': One of those silvery blankets you find in first aid kits. They are very good at reflecting sunlight away from your computer monitor, so you'll be able to hack during the day. Most tents let in a *lot* of light and rescue blankets are one of the cheaper ways to fix that.
*'''blanket to sit on''' and place your laptop on. You might not want to sit on a dew-covered ground in the morning.
*cosy '''sun chair''' for hanging out
*'''chairs''' and '''tables'''

=== Other equipment ===
*your '''ticket''' (A print-out is more resistant to failure. ;))
*cash: while thanks to the [[WHY2025 Payment System]] the 'official' points of sale (bar/foodtrucks/merch) will accept cards (or cash-bought QR codes), villages will appreciate cash donations/payment to help pay for their food, workshops and other activities. There will be no ATM at WHY.
*default meal utensils (like '''knife, fork, spoon''', spork!, '''plate, mug''')
*'''penknife''' or '''multitool'''
*'''3D printer''' and/or '''laser cutter''' not only are they fun, but it could also easily help out someone else who needs a part replaced/redesigned during the event. (for example, when the pressure seal on the Amalettomat nutella dispenser blew up due to a software bug, a handy hacker with a laser cutter saved the project. Many more free pancakes were handed out thanks to them. ~~cavac)

There will be an electronic [[badge]]. You will need:
*a USB-C cable
*laptop or '''USB-charger'''

You might also want to bring:
*'''powerbank'''
* Fun parts to add to your badge, who can make it fly?
* one 2x3 straight through-hole pin receptacle (2.54mm pitch) for SAO (shitty add-on) peripherals
* one 2x6 right angle through-hole pin receptacle (2.54mm pitch) for PMOD peripherals (FPGA)
*'''soldering iron''' and '''tools''' to retrofit the above items (or use hackcenter equipment)

=== Computer and infrastructure ===
*your '''computer'''(s) - and basic '''tools''' you will need to repair it, including OS '''Install DVDs/USB-drives'''

*as many '''ethernet switches''' as you might need for your equipment and to share to neighbors. Don't forget the power supply.
*Equipment for '''802.11a or 802.11n''' on '''5 GHz''', since 2.4GHz tends to get overcrowded. DO NOT bring your own APs. See [[Network]]
*maybe a bunch of '''spare fans''' - heat and dust tend to kill CPU/power supply fans
*a '''list of your trusted SSL keys''' (and check them beforehand!).
*a configured '''ipfw''', think about an IDS (just for fun)
*'''gadgets''' with all kind of blinky, geeky features as conversation pieces

*pinball machine(s)

==== A note of caution about electrical equipment at camps====
READ THIS BEFORE CONNECTING EQUIPMENT PLEASE: [[Facilities#Power]]

== Things to leave at home ==
Must
*'''Dogs''' and any other pets '''(Exception: service dogs)'''. Camp is not a very dog-friendly area. The reasonable exception here is any pet that can be switched off and/or reprogrammed (Aibo, Furby, ...).
*'''Your''' home directory and other '''data''' you don't want anyone else to see
*'''Microwave oven'''. It *may* disrupt wireless networks. A typical tent is not the ideal position to defend yourself against an angry mob of hackers. Also see next point.
*Very '''power hungry devices''' (like AirCon, electric grill or oven, electric water cooker, hairdryer, generally '''anything that creates lots of heat''' or cold). The power grid is always a problem on the camp. So please think twice if you really need all that luxury. '''Incandescent lamps''' have poor efficiency, consider bringing FL or LED lamps instead.
*BBQ that run on solid/liquid fuel. There is a "no open fire" rule in place, meaning that only gas-fueled barbecues are allowed. See [[Team:Fire]] for more info.

== Things to care about ==
*There are cables and drainage in the ground so NEVER pierce or dig up ground deeper than 30cm (tent pegs, grounding/earthing nails, posts etc). If you absolutely need deep nails or pits, contact the event team on site. (NOTE: this is not final yet, please recheck.)
*'''No open fire''' /charcoal-powered BBQ, outside the designated fire area.
*'''rails''', watch your step
*Obey the airspace control rules for any flying object. See [[Drones|rules on drone flying]]!

*If you get too drunk, we have permanent marker pens.
*'''Drink more water'''. Dehydration is a common problem at this kind of event.
*The camp is a community event. If someone ask for a few minutes of your time to help at some task, '''please help'''.
*'''Follow the hacker code of ethics!'''

== Things to check beforehand ==
*If you have a new tent, build it at least once at home. When you arrive at the camp, it might be dark, raining or both. This makes putting up a tent a lot harder when you still have to read the manual!
*The same goes for sleeping bags, camping beds and everything else you might need to set up basic camp.
*If you're planning to participate in a village, contact the organizers of that village as early as possible. That makes planning resources a lot easier.
*As a backup to your smartphone, consider printing out maps of the area and/or update your GPS. You wouldn't be the first hacker we lost on the way to the camping site.
*If you're traveling by train, bus, hitchhiking or by plane, you might want to pack your equipment a week or so before setting out to travel, to see if you haven't over packed. If you can't carry it, you might have to reduce your equipment or maybe find someone close by who can take some luggage -> [[Carpooling]]
*Back up of your data (you did that already, right?).
*Think about doing a clean re-install of your computer to limit the amount of data that could get published to Wikileaks "by accident".
*Contact your friends you want to meet at the camp. Especially if you arrive early, you might schedule a meeting beforehand. All that fancy technological wireless stuff like WhatsApp, video calls and so on might not work during the setup phase (no power) or even during the camp.
*Download music + podcasts + movies to your phone/tablet beforehand, you may want to listen to something nice when network is not available or during the travel to the camp by car/campervan.
