IF your interested in having a high output alternator built or a dual alternator setup. you need to see.(MR.MARVIN)at GEORGIA POWER SYSTEMS .this man is a genius.an will get you the power your system needs.all his work is custom.

This is an electronically fired pulse motor. It is using a device called a " step down adjustable switching regulator" that is 90% efficient to control the supply voltage . A small solar panel is used to supply energy to a 5Ah 12v lead acid battery. That energy is then metered out to the motor thru the regulator. More energy goes into battery during the day than the motor consumes. At night the motor runs on the stored energy. The pulse motor circuit is a John Bedini patented design.

To further reduce the RPMs the station will be exposed to I try out a simple 3 legged fixed 6 volt regultor, a big capictor is added to help get the motor started up.

Here is my "Backup Generator" to my backup Honda eu2000i which has some quirks, Maybe it's because this one is a cheaper unit, which atleast for me is a plus as pricey stuff sucks! & the best things in life are free (or close to it), anyway this was the first start off this Coleman Pulse 1850 Generator which I picked off my buddy who likely trash picked this (at the time the genney didn't start but I quickly determined that the fuel petcock was off [& got an idea to check the Honda on which I found out it was lacking!?!?]) anyways I say in my video that I will sell either one but at this point I will rather retain both atleast for now & the more I look at this the more I like besides being a bit louder than the Honda (it's got redneck written all over it & I'm cool with that!) ~ Even has a fuel petcock to prevent gumming up your carb - who would have thought of that at Honda? the only thing that I'd wish was that this thing had was voltage regulator, & not sure if there is a fuel pump to be able to use a non-pump, non-gravity feed aux extended run fuel system. btw the black baggy on the side is some neatbags attempt at keeping the battery charging cables in place ;) Rate Comment or Subscribe! Thanks, Dan

Little Bedini motor and BIG solar panel running indoors with just ambient light and no batteries. Light energy is being controlled by a "step down adjustable voltage regulator" which allows energy to build up in a large capacitor before it feeds the motor. Energy coming off the collasping magnetic field of the motor drive coil is recycled back into the motor.

I've got the voltage regulator turned right down. You can't see it well, but the pressure gauge is pegged at nought. Even so the steam regulator has to be closed down to really slow the engine. Towards the end I turned the power up to max to see how long it would take for steam to build while running flat out. It took longer than the movie ;)

I bought the phidgets 0/16/16 board and then discovered I could not reverse polarity for stepper motor driving, although the board could handle the current: 2A drivers are already on the board. So I added the L298N H-bridge and a slew of too many parts. The current regulator is LM317T with 0.77 ohms across the input to limit the current draw to 1.6 Amps. You can find the wiring diagrams with the datasheets for those chips. The bipolar motor has four wires. The phidgets output block uses two direction outputs and two coil-enable output wires to control the two bipolar motor coils. I used 1500 ohm pull-up resistors on the L298 inputs. So the phidgets is actually disabling (grounding) those inputs by turning ON the phidgets output. I wish I bought a stepper add on board. It would have been easier. Here is one: www.robotshop.ca
