+# Project Ideas
+
+## Laser Cut Projects
+
+- Laser cut things from [here](https://blogs.loc.gov/maps/2025/03/globe-gores/)
+
+## Thermal Camera Projects
+
+- Pair camera with iPad and fuse the 3D model generated by the iPad with thermal input.
+- Use Raspberry Pi + screen + camera + thermal camera + (depth sensor?) to fuse thermals and camera input.
+
+> - One approach requires learning iOS app development but may be more useful in the long run.
+> - The other needs more hardware but could be fun for other projects too.
+
+### Additional Ideas
+
+- Use DeepL to segment the image input, overlay the thermal image, then do a best-fit to impute segment temperatures.
+- Track motion in the camera input and overlay thermal input (copy what the iPad does). Potentially use OpenCV.
+- Can the Raspberry Pi GPU be used with compute shaders yet?
+
+## Getting Into SMD Manufacturing
+
+- Start with a simple test board — maybe an ESP32 datalogger.
+- Get tools.
+- Decide how to heat: maybe a DIY hotplate?
+
+### DIY Hotplate
+
+- Already have the hotplate.
+- Do I have the switches though?
+
+## Custom Home Assistant / Smart Speaker
+
+- Use existing Raspberry Pi.
+- Add Home Assistant.
+- Add air quality sensor.
+- Add RGB LEDs for display.
+- Add a small screen for extra metrics.
+- Make a nice white case with plenty of space.
+- Maybe add a microphone and try to find an open source smart speaker:

+  - [ODAS on GitHub](https://github.com/introlab/odas)
+
+## Other Ideas
+
+- Replace driver board on Ender 3 for quieter operation.
+- Hook up PSU control with a transistor.
+
+## Build a Linux System from Scratch
+
+- [Linux From Scratch Guide](https://linuxfromscratch.org/lfs/view/stable/)
+
+## Adjustable Bedside Lamp
+
+- Adjustable colour temperature and brightness.
+- Use high CRI LEDs and RGB LEDs.
+- Power with 20V USB-C supply.
+- Add microcontroller and rotary encoder.
+
+## Custom Low Profile Keyboard
+
