New MPPT Board Prototype

This is a demonstration of a wind turbine max peak power tracking board that I designed. It has many features that should make it useful as a turbine characterization tool. The firmware in the board is very basic and I will be making improvements in the future.

nice vid... Have you ever tested ur board on a bedini motor.... I have a bedini motor that I gets 161V and I can't do nothing with. I try to reduse to 12v dc and try with a an inverter but my motor speed up with load and burn up my invertor. I love to test your board on my motor if this is an option.... email me thanks

@roystervi No, the demo was with the second board made. I'm making a few more to try on wind turbines. I never considered using it with something like a bedini motor, but if there is a high voltage source, the board should be able to use it.

LOOKS GREAT! CAN IT BE ADJUSTED TO ALLOW A NO LOAD THRESHOLD FOR EASY LOW WIND START UP?

@muddymuddymuddmann When I get the 'good' firmware done it should be smart enough to realize that if the turbine just started up, it should slowly ask for torque to allow the turbine to start.

Nice to see you have all these people snowballed.

Care to explain how 10, maybe 11V OTV mysteriously is able to get the filament hot enough to emit light, by running it through a BUCK converter? At the same speed (and what even seems slower)?

What you're proposing (and your followers don't understand) is that to overcome the resistance in the coils (and light the halogen), is that you'd need to be crank at an RPM that produces upwards of 80V. Not happening with your arm, pal. Try again.

@MadScientist267 BTW you can see the rectified alt voltage (before the buck converter) on the meter in the video. It's clearly near 100v.

Great work, I'm anxious to see the final product!

I'm impressed with this work. The kids at our local Jaycar.com.au electronics store in Australia seem to think there's no distinction between controllers for solar and windgens. I don't understand your theories fully, but what I'm guessing is that cogging and load would seriously prevent a turbine from running even if there was enough wind. Is this the same problem with all turbines? Or is it just an issue with the type of generator you're running'? Any suggested links are welcome. Graham

top notch

@sjh7132 WONDERFUL! KEEP UP THE GOOD WORK. I'M LOOKING FORWARDS TO THE DAY I CAN MAKE ONE OF THESE INEFFICIENT CEILING FAN WIND TURBINES PUT OUT WHAT THEY REALLY SHOULD. THEY PUT OUT VOLTAGE WELL, BUT LITTLE AMPS. IN THE MEANTIME, THE BEST OUTPUT I GET IS RUNNING 12 STRANDS OF LED CHRISTMAS LIGHTS. OR 50 TO 100 WATTS TO THE BATTERY BANK.

KEEP SMILING AND HAVE A BALL.

@sjh7132 thanks for the quick response if you want someone to try out ur demo board on a bedini motor let me know. if this board does as describe in the vid the bedini motor would be a great test. thanks again

Hello mr Mr Madguy I am the builder of the Mann Smart Drive if you go to my CNGBOB you will see me redoing the controlled test. Steves controller let me make over 121 Watts in to the grid by one hand. and I show the same test using the top of the line GinLong Grid Tie and only can make 60 Watts.
