And it would be much cheaper too.

Imaging a group building an managing a robust power supply design for Cubesats that can be immediately ordered from JLCPCB. With a well maintain BOM list.

My dream is to build an open source CubeSat kit (hardware, software, mission control software) with an experience similar to Arduino. Download GUI, load up some examples, and you're directly writing space applications. Ideally should be capable of high end functions like attitude control and propulsion. The problem is that designing and testing such a thing is a rather expensive endeavour. So far I haven't found a way to get funds to dedicate time on this kind of "abstract"/generic project, most funding organizations want a specific mission proposal that ends generating useful data from space.
