Necro I know, but this thread came up on a google search. Ramps switches the ground connection on all outputs. Use a buck regulator to output 12v, and feed all of your fans with that. Ground back through the ramps board will switch it for proper pwm control. Same can be done for hotend or anything else you need to control on 12v.
I like it. A nice simple thing i can knock up on the spot as an when needed. Will salt and sugar make the angles more precise? Have you tried with maple syrup instead?
Love it!Me and the kids made similar using an old remote control motorbike for the brain and motors, but we used a toy batboat as the base and motorised that.Ours came out more as a swamp racer, and we turned the fan motor side to side to steer. Point is that even busted toys have life in them yet!
