MOSFETS and relays
airman00:
Where can I get relays for a motor that is 24VDC @ 11 amps? I can't find it anywhere. It should be cheap and should be switched by 4 AA batteries.
If there are any cheap H bridges or motor controllers that fit my requirements, please tell me about it!
Bajanick:
Try http://www.allelectronics.com/ They have a 3-15 volt, 18amp SSR.
and theres this one also.....

For H-bridges theres lots of places........

Robotmarket place sells quite a few different makes and models.
airman00:
How can I wire a mosfet so that is works like a relay.?
Can I wire a MOSFET so that 5V@300mA switches 24V@11A like in a relay?
What are the advantages of using a MOSFET over a relay?
airman00:
Should I use 2 DPDT relays to control the motor to be bidirectional or can I use MOSFETs to do this? Will the MOSFET be cheap if I need one for 11 A?
Please Help

You could use a mosfet to trigger a relay im sure, but 11A through a mosfet im sure would achieve but a pretty picture... pretty and painful if your close enough
