EBS - Ethernally Blink Solar (Ewigblink)
The EBS project is based on a pcb with photodiodes (PB333) and a supercap (HV0810) with 1F so that in combination with sunlight the state of the led starts changing.

Hardware
There are two parts of the hardware. The pcb and the housing of the EBS. The pcb is created with KiCAD and the housing with FreeCAD. All files are built with github actions so that they are ready for a production environment. The housing is printed with a 3D-printer (Dremel 3D40).
PCB
The circuit board is populated on one side (Top). The best way for soldering is within a standard soldering system.

Mechanical
The housing has a tolerance of 0.2mm on each side of the case. So the pcb should fit perfectly in the housing.

Questions
How big is the Ebs PCB?
It measures 44.4 × 27.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ebs use?
21 parts, built around the BC547 and BC557. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ebs KiCad files?
From the 0x007E/ebs repository on GitHub, at the commit this page was made from: the board is pcb/EBS.kicad_pcb and its schematic pcb/EBS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ebs design in my own project?
Its repository states no licence, so its author keeps all rights: ask 0x007E before reusing the design.
