Questions
How big is the ClusterBlaster PCB?
It measures 65.4 × 50.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ClusterBlaster use?
20 parts, built around the L7805 and LM339. 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 ClusterBlaster KiCad files?
From the surdu/ClusterBlaster-Hardware repository on GitHub, at the commit this page was made from: the board is ClusterBlaster.kicad_pcb and its schematic ClusterBlaster.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ClusterBlaster design in my own project?
Its repository states no licence, so its author keeps all rights: ask surdu before reusing the design.
