An educational DIY kit for converting a disposable vape into a rechargeable flashlight
early prototype of the kit photographed by Daniel Wilkens, used under CC BY 4.0 / cropped from original
The kit is used in workshops to educate about:
- environmental and social impact of resource extraction
- resource consumption of electronics and disposable products
- basic hands-on soldering skills
It is accompanied by a zine containing contextual information about these topics and instructions for assembly.

The pcbs were developed with KiCad 8.0.
KiKit 1.6.0 was used for the panelization of the PCBs for production.
Visualizations were made with Blender 4.2 and pcb2blender 2.15.
The fabrication files were generated with Fabrication Toolkit 5.0.1.
The files for 3D printing were generated from OpenSCAD 2021.01.
PCB and 3D printing source files are licensed under CERN OHL P 2.0

Questions
How big is the Vape light PCB?
It measures 58.3 × 15 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vape light use?
46 parts, built around the AL8860WT, LM27313XMF, 74LVC1G02Z and 74LVC1G175GV. 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 Vape light KiCad files?
From the sbyd-space/vape-light repository on GitHub, at the commit this page was made from: the board is pcb/vapelight.kicad_pcb and its schematic pcb/vapelight.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vape light design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
