Yeah, I have a mechanical prototype working right now. Will post some pictures when I get home. If everything goes well, I may release all openscad/stl/svg files.

Here is my current prototype.




The goals of this gimbal are:
1.) No center detent (smooth transition in the center), with lighter spring force than the Warthog
2.) Can be constructed with off the shelve and 3d printed parts
3.) Durable enough to support metal grips from Thrustmaster
4.) Size should be small enough to be desktop friendly

For the next prototype, I want to make this gimbal smaller. I'm waiting on smaller bearings to arrive to make this happen.

Well.. I finally received my goods from Taobao. It took extra long because the seller opted to use Taobao's international shipping. The goods get shipped to a local holding warehouse, where I then have to pay extra (another $20 something dollars) to get it shipped abroad. I didn't know about that part, so the goods were sitting for a good while before I figured out that I had to fork over more money. So total came around to something like $50 - still not too bad.

Things seem to work well, I haven't screw around with it much yet. I am still finalizing some changes on my smaller gimbal design, once that's done I'll dive into the electronics more.

Here is what ~$50 got me:


It seems like the seller is taking orders for the boards again, but from what I understand based on my poor reading skill, he is not shipping till 4 months later - something about busy with life.

I am just designing shift register for 32 switches, I shall share it, also I shall design shield for pro micro with plenty connecting options. I was looking on ebay for pcb manufacture and it is not expensive, we'll see but all together should be cheaper than 50 $ for multiple pcbs. I am still learning eagle cad but i am getting better. If you have ideas please let me know.

This my idea for shift register board. In this case it has only 2 4021 chips, for 16 switches total. Now I'll make PCB with 4 chips for 32 switches. I used a little different pin out for switches. On picture you can see 2x8 pin heads, 2 pins for each switch, I think it is more practical. I used resistor networks instead of individual resistors (red). Yellow is capacitor, it is on Thrustmaster's PCB so I added it as well.

Nice thing is that Eagle CAD can export its files to sketchup.



I just need to learn how to create gerber files needed for PCB manufacture in China. There are many offers on eBay like THIS. 10 PCBs for 25$. 4021 chip costs 0,2$, in the end it is really not expensive.

I'll post files soon..

I think I finished schematics and board layout, I think I connected everything right. This is how it should look like.





Maybe I could add two mounting holes. Dimension are 85x25mm.

For use in old grips like F-22PRO, CH... is need more buttons, so a 3x CD4021 is ideally for this grips grip.

The version with 4x CD4021 = 32 buttons, the question is for what use?

Because with 2 wires per button result in a lot of wires...

BTW - In Tm shift register is used 1 pin for each button and a common +5v for each 4 pins, in case a HAT.
