Phemla (PHoton EMitting LAntern) is a solar rechargable and not a so portable lantern. Perfect for camping activities ⛺.
The idea and the original design was developed and sketched by a Scout group.
Make this project as much open source possible, starting from CAD to CAE files.
Design wins:
- Overall part count is very low
- The parts are easy to fabricate (possible machining processes)
- The machine is easy to assemble
- Maximizing usage of materials like glass and wood
First version. It was used a power bank with usb-c for recharging purpouse and usb-a for withdraw necessary output for the LEDs. Solar cells are not used in this stage.
Internals
Particular is visible the power bank
Mark 1 - Turned on
Improved version. It was added a solar module.
Still in under development.

- Add design files Reduce number of screws
- Improve plexiglass fixing or laternative solutions
- Use standard 5mm LEDs instead of using SMD components (more user-friendly)
- Rotate 90° usbc feedthrough
- Reduce costs (mostly derivative by PCB design)
- Reduce overall dimensions
