Gauntlet
Features:
1.The shape of gauntlet is symmetrical which could fit both left-handed and right-handed users.
2.The gauntlet is adjustable by using elastic robber band and velcro.
3.The shape of gauntlet is simple so that potential users are able to cut various soft metarial easily with scissors instead of using laser cut machine.
4.Gauntlet itself actually indicates identity of the player as a "warrior".

Questions
How big is the Armbow PCB?
It measures 91.4 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Armbow use?
39 parts, built around the BSS138 and PZT2222A. 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 Armbow KiCad files?
From the moonbeaminteractive/forearm-weapon repository on GitHub, at the commit this page was made from: the board is hardware/armbow.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Armbow design in my own project?
Its repository states no licence, so its author keeps all rights: ask moonbeaminteractive before reusing the design.
