I wasn't there for a while, however I have some amazing news now!

After 1 month of struggling, after a month of trying different complicated electromagnetic structures, I finally found electromagnet (which was lying on my table for 4 years for now and was a part of various experiments with control board) nice enough to try out something with them.

As I told in previous post, I wanna utilize magnetic field better, then... here we go!

Looks evident? Well, it wasn't evident for me, even if I knew, what magnet (which I have) produces same attraction force, as a reference permanent magnet. I thought, that field shape isn't proper for this use. Today, experiment shown, that there is nothing bad with it at all, silly me!

And there is even a magnet with desired shape on a market!

Yeah, that is a magnetic lock )
Widely-available thing. Also can be hand-crafted, but it's not the point right now. Is it bad? Not at all! With it, our muscle supposedly can achieve 1.2kg contraction force with only 3W power consumption + work performed by muscle (in other words, by a magnetic field)

What we have now?
- fully-working control board, which saves 70%+ of energy for now, nice
- fully-developed stripe production process, pretty convenient
- electromagnets to power up everything!

What remains to do to build first working prototype?
Well, nothing! Except of urge to buy some magnetic locks
Stay tuned ; )
