Very nicely done!

Thanks TinselKoala.
Doing graphics designs is my "futur" independant work (waiting administrative papers).
I should must be good at that 
Also, if you need some graphics (no benefits money, just given service), I'm the guy to ask !

Ho I want to ask you, actually I check what's available for buying mosfet, I've found the one you use IRFP360 and an IRF840. The 840 handle more voltage (500v) but have a greater RDSon restitance (0.85ohms) than the IRFP360 (0.20ohms). Because datasheets are sometimes not so revelant, I've checked the On-Resistance vs Temperature graph, and it seems pretty close on each other near to 1ohm.
For this application & for more advanced stuff (I need to learn more before), which one would you recommend-me ?

Edit, what about the STW10NK80Z ? (N-CHANNEL 800V, 0.78ohms, 9A, 160W)

I've find 2 other motors similar than the one I use, for less than 3€ ≈ 4$.
The first is a little baby stepper from a CD-ROM drive, its really small and have a lot of frictions (I will fix it).
Also there's 3 hall effect sensors, which will let me use it as trigger.
The second-th is much more larger than the one I actually use, and would be mounted manually.
