 - **hardware**
-    - **solder dispenser** - level up from the tweezer and hand-squeezed syringe
-    - **word watch** - inspired by those word clocks
     - **wireless solar keyboard** - full size, swappable keys, ch32 w/ nrf24, solar powered, usable in UEFI/BIOS
     - **Linux board** - probably an NXP or STM32 chip, maybe a Zynq
 - **software**
+    - **Zephyr USB Rubber Ducky**
     - **autodbconv** - LDF/DBC parser built in Rust
     - **JABI mobile apps** - built in Flutter for cross-platform deploy
     - **ePaper Zephyr support** - made a breakout board a while ago, try adding to Zephyr
     - **CAN/LIN DFU for Zephyr** - perhaps build it on UDS or devise custom protocol
     - **MCUboot FSBL** - updatable bootloader!
-    - **bootloader dynamic linking** - app calls functions provided by bootloader to save flash
     - **acoustic keylogger** - lots of articles online, seems interesting
