After almost 2 months of not updating this Hackaday.io page, I am finally happy to announce that the 10AxisFeatherWing is complete!

I was busy trying to perfect the boards, and my gosh did it take two months!

During those 2 months, I have learned the following:

  1. Use stencils rather than hand soldering. Especially if you have tiny parts and if some of your components have no leads. I threw away $100 worth of failed boards trying to go cheap.
  2. Check your board design before ordering. I uploaded a board design I did not check, and I got a board that does not have a trace to ground on one of the pads. I did not let that $20 go into the drain, though. I used it to make a partial board that tested the unaffected components. Here's a photo of it:
    It worked!
  3. Have a heat gun. You cannot solder parts under components using a soldering iron, unless the pads themselves are visible.

My university hackerspace provided the right tools to prepare, solder, and test my boards.

Also, I will be scrapping the 10AxisFeatherWingLE variant. I had made 3 prototypes, used a stencil, and tested them. All three of them released the magic smoke.

I am thinking of making more hardware, since I wanted a modular Thrust Vector Control system for rockets. Like what Joe Barnard does in BPS.space!
