FET Bed Heater Board

On the relay board, I recall maybe a couple of other threads where, in addition to providing a MOSFET switch, the person was adding other useful stuff onto their custom board. For example, adding an ABL servo or a Raspberry Pi Octoprint controller can leave you starved for 5V, so people were adding 5V regulators on their boards. I remember suggesting that providing 12V distribution and a few lightweight MOSFETs for things like fans or lights would be a good idea.

Im actually thinking of following in TechMasterJoe footsteps and using an ATX power supply. For me atm its hard to guess what will and will not be useful, I just got the check today that will be going toward my 10" Pegasus, I have spent the last week or so just looking at things I plan to change from the start. The Mosfet Driver seems to be the easiest to tackle and I can see it being used for other things, I just ordered 3 boards and parts today. p.s. I can see some Chinese guy making and selling them for $3 in a few weeks time lol.

I will say the ATX power supply's nowadays can give more then 1A in standby on the 5V line, this can power all the small stuff until the controller decides it needs more power and turns the supply on. I also looked at reworking the Ramps 1.4, but thats a long battle for later.
