Rocketry

The rocketry components that you find here are a culmination of years of my experience as an electronics engineer being involved in high power rocketry.  The components that I have developed are used in the design and fabrication of rockets with emphasis on deployment and tracker electronic bays.  The electronic bay components allow for the re-use of bays between rockets and also to allow bays to be reconfigured as technology changes without having to rebuild completely.  You will find support for 38mm BT60, 54mm, 65mm, and 75mm for all types of bays. There are also general purpose "assistants" to make building easier for wiring and marking holes for mounting.

You can get an overview of the product line on the Diagrams, How To's & Concepts page which details wiring, assembly, and concepts.

I hope that you find the products of interest and would like to incorporate them into your next rocket.
