Welcome to Vx Aviation, your source for FREE electronics and avionics device designs


October 29th, 2012: Reliable, flight-tested avionics from Canada’s Vx Aviation are released as free open source hardware designs and are now available on the MakerPlane website.

MakerPlane, the open source aviation organization, and Vx Aviation, are pleased to announce the availability of a range of avionics as free and open source hardware designs.  The plans and installation instructions are available at no charge for download on the MakerPlane website.  The Vx Aviation avionics designs include audio devices, such as tone annunciators, mixers, stereo music adapters and cell phone interfaces that work with any aircraft radio or intercom systems. Also included are annunciator lamp controllers and wiring hubs that greatly simplify avionics interconnect.  MakerPlane will be offering electronic kitsets, printed circuit boards and fully assembled units based on the open source designs.

This site is a summary of the various Vx Aviation product designs that are now available from MakerPlane www.makerplane.org.  MakerPlane offers free design source information on the Vx devices as well as blank circuit boards, kits and finished products.  The previous Vx Aviation site that required login has now been discontinued in favour of the MakerPlane support network.
