- # Sponsoring the project
-
- All development on this firmware is done for the greater good of mankind.
- You can use it for free. However, if you do feel the uncontrollable urge
- to contribute financially to the project, you can do so through
- [this PayPal link](https://www.paypal.com/paypalme/bedsidelamp2).
-
- This account is used for acquiring hardware and software licenses that
- I use for my open source development. Specific hardware that I bought for
- this project were:
-
- * An extra lamp for development and testing, so I don't annoy my wife
- with buggy deployements ;-)
- * A dedicated serial to USB adapter, connected to the development lamp.
- * a simple 8 port logic analyzer that helped me with reverse engineering
- the I2C protocol of the front panel.
- * Various wires and buttons.
- * An Arduino Uno R3, to [help out somebody in the community forums with
- flashing the lamp using the Arduino](https://community.home-assistant.io/t/hacking-yeelight-fw-enabling-lan-control/284406/214?u=mmakaay).
