<Must-still-be-uploaded> System administrator, please find a way to allow me to upload a file called:
hopebadge-0.8.14.bin
...if you want I will compress it in some way or modify its filename or file extension. Nothing I've tried so far has worked. If you want to test this, just make a empty file with the name above and try to upload it.
Badge Clinic
Come by the Badge Clinic, and one of our specialized nurse practitioners will help you with all of your HOPE XV Electronic Badge needs.
Come by for:
- help with assembly
- to find out more about features
- to hack on the badge
- to volunteer to help others
Description
The HOPE XV badge was given to in-person HOPE attendees.
Two 'pro' versions (with additional components) could be purchased at the Badge Clinic.
Features
The HOPE XV Electronic Badge has lots of cool features!
- Lots of colored blinky lights (16 WS2812 or similar)!
- ESP32-C3 microcontroller
- MCP73871 LiPo LiPo battery charge controller.
- Feature 2
- Feature 3
- Feature etc
Open Hardware
The HOPE XV Electronic Badge is totally Open Hardware!
- The repository linked appears to be correct (REL_0.8.14), but does not specifically mention HOPE, so looking for confirmation.
It is also totally hackable.
BOM
This bill of materials is based on the KiCAD project. There are a number of components that are not populated on the badges distributed to attendees.
