Just to write a short update.
The project is evolving. Slow moving indeed but keeping the direction forward.
In short what happened during last 3 months.
1. The negotiations with Polish RR Companies are moving foreward. If everything goes as planned we should get the legal permission for test run installation. Can't say any more, but ... fingers crossed.
2. We have a PCB version of the prototype.
3. The first "art of the bodge" prototype is still running. 171 days non-stop and counting. It's just unbreakable:)
