Thanks for the surplus suggestion. To be honest I watched each video I could find from the 200 amp youtube videos and it was way to blurry to see much of anything except that there is a ton of copper where the three pins of the mosfets are. Is it safe to for example bend the pins of a mosfet and...

Sorry about omiting that. Modules do seem rather expensive though. Is there no good way to do it without them? For a hobby project. Definitely not production.
But how about the YouTube video showing a 200 amp device. It looks like the Mosfet is conducting through solid copper bars. I would prefer such a solution if possible.
Huh! That's actually a great super simple way to check the cable is not broken anywhere. Happy late New Year and thanks for the link.
Edit: Does it pulse across the wire at a frequency or just a dc voltage?
I can't seem to find anything on the topic of mounting high power Mosfets directly to hunks of metal to carry a bunch of current. How is such a thing done and does anyone have a link to someplace I could look at to get a good idea of the property way to connect the drain, sink, and gate if I...
It has been very helpful and I also believe the thread title question has been answered so I will keep my other questions for another thread so other people can find answers more easily. Thanks everyone.
Sparkfun sells some simple rf transmitters but you might want to look into bluetooth as it seems a lot more reliable. The ones sold on ebay might be a decent choice. I have two but I haven't used them so I can't say for sure they would work in your case. In fact does anyone know if such...
Ahh I see. Thanks for the replies. I wanted to go logic level because of my concern with turn on times. I am interfacing it to an atmega168/328 28 pin package. From what I understand The turn on time should be quite a bit faster than the pwm signal which would be best kept out of the audible...
I am not limited. I simply though surface mount was the best solution except for the fact that they seem to conduct heat to the pcb which is not ideal for me. So from what I understand the best option is to go with a to 220 and mount a heatsink on the back drain?
Edit: I looked at some to-220...
I am trying to design a motor controller (H-Bridge) capable of 100 amps continuous. I have switched mosfets multiple times since I am unsure of what type of mosfet would be best for this sort of job. I read DirectFET mosfets are good for use with heatsinks however they don't seem especially...
