Undergraduate engineering level project

Hi I'm designing a magnetic levitation model train just like this The only difference may be to use disk magnets for tracks instead of strip type magnets (I'm considering both options at this stage before deciding finally). The engineering part of design is easy, however, I want to know and...

Hi. I have to design a controller circuit for switched reluctance motor. The topology to be used is asymmetric half-bridge. The motor current is 50A at 50V. I need help in the selection of controller. I have both options either to use embedded or totally analog controller.

Hi. I have to drive a motor using TI's CC2540 blue tooth IC. The order is already placed for IC and CC debugger. I have very limited time to design it's hardware as well as software. I think hardware part is easy for me. However in case of software I need verbal suggestions as soon possible like...

Please see attachments.

Well bro I made changes attached in pic herewith. I simply raised Vcc/2 from 2.5 V to 6 V while keeping signals from hall effect sensors at 2.5 V with this circuit. For this to happen please note that resistors R19 & R23 should be of same value and similarly R18 & R24 should be of same value.

Finally it's success with some changes to the original circuit.

Hi there. Now I also added the said resistors & capacitors however no success.

Hi. I'm designing a magnetic levitation board based on schematics attached herewith. However it does not levitate the magnet. Plz note Q1 is P channel MOSFET. Also note that I used coil L1 as X1 & X2 and coil L2 as Y1 & Y2. Where Xs and Ys represents horizontal & vertical directions...
