Re: Powering a 12v LED bulb above printer, from a 12v supply?
How bright do you really want the lights? There are some LED strips that can get very bright, but you usually want to made sure they are securely attached to something that will help dissipate excess...

There are always amp limitations, but most circuits are designed for 10A - 15A as long as you use the right connectors as well as MOSFET and heatsink choices. You do need to watch the connectors...
View ArticleExternally powering mk2a heatbed
As my electronics are broken, how can I control the PCB heated bed directly from the power supply? It is 12v 20A, but don't know what resistors should be used. What power is needed to maintain ~100C?

Well, just connect it directly - it will only draw the current it needs. The problem is, you will have no temperature control.

I'd recommend getting an arduino kit - this can double up as the programmer, so it's not a waste, also handy if you're not that into software (I am, hardware's a secondary thing to me) I cut my own...

For those brave enough to etch a board, Gen7-ARM exists. Very affordable, but also work in progress. 48 MHz and of course 32-bit. One of @bobc's(!) printers is running it. For partial instructions,...
