Hi Kbird, I`m glad to know that you were successful, good job.

Be careful not to forget jumpers (wires jumpers). You can see them on the picture in Sprint-Layout 6 Viewer:


That was my first ShReg board:




It is not problem of firmware, make sure about right connections and software settings.



Solution is perfect all connections, shielded or twisted cables/wires and resistors (e.g. short data wires=10kOhm but longer wires=1kOhm) and capacitors (between VCC and GND) on both sides for filtering out, sometimes it is ghost hunting :-)




Thanks guys for compliments.
I drew all main parts and my father made them from Alluminium (shafts from steel) at factory. I bought bearings and other necessary parts (screws, nuts, washers, spring...) and put together at home. Bearings to freezer and Allu parts to oven (my wife was very happyyyyy :-) ) and let`s go press. Some cutting the threads and drilling holes..... some electronics... it was not difficult :-) Rudders are very precise, no clearence, because I used 10 pcs bearings. But idea is not my own. I saw it on some Russian web I am not sure where (it was 4 years ago) and cost was about 300$ and problem how to send them from RF to EU so I used their principle of mechanics, only from photos I drew main parts, others I had to think up, dimensions, particular details and electronics are my own.

Bye
