    Looks as if you are about to see the wonders this project can teach and present to you. It always amazes me to just sit and watch this setup run and run without using and decreasing battery bank voltage.

    Each step taken is a challenge but always good to see results that encourages toward the next steps.

    • Progress

      Still at it. Trying to get generator rewound. Testing a multi-filar parallel series connected wire. Not sure if heat will be an issue as was with the prime mover that was wound with many strands multi-filar winding. But finally wound it the correct way.

      No big news just checking in.

        I made it back from the dead. Finally. 3 weeks of hell with the flu
        but I am back at it this week.

        PS I have been running my 3 battery system now for 6 weeks even while
        I was sick. The last test revealed that the Alum got below 50 degrees
        and all I was able to get out of my 4 pack of batteries was 480watt/hrs
        or 120watt/hrs per 16ah 12v battery.

        This is the first time I ran it all of the way down to 10.7vdc from a full
        charge. I was not running the mod mtr, I was using an inverter powering
        a light bulb at 20watts. It is a bright LED bulb. Over a 24hr test.

        Not very significant but I am running it.

        Stats for this 16ah 12v battery go like this.

        12v is the running average from 13v to 11v and using the C/20 rate
        I can safely draw 800ma at 12v for 20 hours. This is

        .800 X 12 = 9.6w X 20hr = 192w/h theoretical but in reality the true
        amount should not be more than a 70 percent usage or 192w/h in
        theory times .7 or

        192 X .7 = 134w/h true watt hrs that leaves a safety margin.

        Remember this is the rating for a single battery and I have 4 of them
        ganged up in parallel.





        Hey Bro.
        Sorry to hear you were sick. I got a stomach virus last night and stayed up all night with pains.

        I only got one side of the larger My1016 genny done last week. It's a tough going soldering those wires back to the beginning of other wires and arranging them so they don't short on each other. Used a hot glue gun to insulate them from each other. But if the generator heats up that glue will melt also. May re-do that side and get a bottle of liquid tape that withstands high temps.

        I'm very anxious to finish this generator to have a poor man's version of Dave's larger generator upright build.

        Good test results. I hope to have some results this week to share.

        • Hi all.
          Last days i was trying to put together a flywheel (like Chas Cambell) and 3BGS with modified motor and MY1020 as gen. I 've not concluded yet but with the setup i have mod motor has not enough power to accelerate the large flywheel to high rate. I managed around 500 cycles per minute for the flywhell, around 1100 for motor, with 12volt battery. I am afraid to put 24 volt because my setup is not very strong as you can see at the pictures. I think i will rebuilt a new one.

          Wantomake, a lot of people get sick this time of the year, myself also, but getting better. Do you mean you rewound MY1016 motor, or you are referring to the new gen you are making.

            Hello liber63,
            Good looking setup. Flywheel is understandable.

            I have the my1016 250 watt motor as prime mover. Matt motor modified. The my1016 350 watt motor is my generator that I'm rewiring. It's a little longer than the 250 watt size.
            I stopped building the larger Dave's upright generator until get more finances and time permits. So far it's all wood, even the rotor will be hardwood I'm thinking. My shop is simple and small so no lathe to turn a rotor out of hard plastic material.

            Thanks for your update. Good to see others building here.

            • Testing wiring

              To All,
              The coffee is hot, the rain is here, and Saturday morning rules.

              The my1016 generator rewind wasn't a success. The power output was very low. The prime mover pulled 6 amps that is doubled from before the rewinding.

              But I never stop with just one try. I think if the motor was a slip ring setup to produce AC there would be more continuous output. But pulsing with a commutator to dc slows the energy output.

              Back to rethink this wiring. But the coffee was a success.

              • Without the proper sleeves to protect the enamel, razor sharps is
                the microscopic pierce thru.

                I rewound one 4 times. On another note concerning the lathe needed
                to make circles. here is what I did one time. You can cut the shape out
                with a jigsaw then secure the main center shaft so it can be freely
                turned then by hand you may grind.

                This is from the magnet motor revelation thread. Keep it turned on,
                turned up and never roll over, think.

                My perfect circle is here, I said lathe but I ground it instead.

                • Another way is to use a bench grinder and mount the disc on a drill. Ease it into the grinder slowly and it will grind down until it is almost round. Then use sandpaper lying on a flat surface to finish it. Good luck. rockhound

                  • For ten years I rough cut my rotors with a Sabre saw or a ban saw ( depending on size of rotor. My bench grinder is mounted in the bench with one grinding wheel hanging over space. I remove this grinding wheel and mount my rotor. Now I can spin it at high speed using my bench grinder. I have lots of different tools that can be used to give me a perfect circle at that point. I simple wood rasp will get it very close, or there is something that looks like a cheese grater that works GREAT on plastic or wood, and then different grades of sand paper. There are a couple of wedge shaped things I made to put sand paper on that I could slide in to a specific distance to give me the exact diameter of rotor I want. I’ve talked about this before, and even posted videos, but those are gone now.

                      • Good advice

                        Thanks to All,
                        That's good advice/ideas to cut the rotor and get perfect diameter.

                        Can't post much this morning, taken wife to dentist.

                        Hope to get rotor diameter and thickness resolved today.

                        • Correct

                          Bm,
                          Exactly correct on a perfect center hole. Turion stated the rotor disc will be pulled by the coil cores as each magnet passes. Therefore wabble in the rotor will happen. The center hole must fit tight and I plan to place a smaller disc in front and back of rotor to hold it more securely. At least that's what I noticed Dave had done with his generator build.

                          The plan is to use hard wood for a good solid build.

                            To All,
                            I post over on the Newman motor finally explained thread about my busy life trying to sell and buy a home.

                            But I'm still (when my wife let's me) studying and building Arduino to catch up to a possible switching battery banks of the 3BGS. Learning C or C++ isn't a walk in the park but will try.

                            Nothing to post about now or for a while. Just an update.

                            • It is good to lock one's self in by his own words. I too am waiting for
                              parts from Gyina oops China such as the hub flange. For a year or more
                              all I could find is a hub for $70- $200 and that seemed to high. Knowing
                              now how to talk Chinese I found what I knew was there for my build yet
                              was not finding these parts.

                              $3 for a small hub and bigger ones a whopping $5 - $10. The CNC and
                              robot type machinery have what is needed to spin a simple rotor without
                              selling off your gold bullion.

                              It takes time to order from half way around the globe to get that poor
                              boy deal. Ain't nothin goin on but the rent. As many of you know the winder
                              I built last year sits outside so now that the weather is in the 60's I can
                              be thinking about winding my coils again the easy way.

                              I have looked at wood rotors and went the other way using tablesaw
                              blades. I want to run 3000rpms to 4000rpms. The saw blades are hard
                              to drill but once you have it done you can't change the shape of that
                              true form. Saw blades when hit ring like a bell because the metal has
                              a very precise mix. It is way harder to change the shape than stainless.

                              The rotors are tempered. I know this is way different than Turions
                              build but you know what they say? "Variety is the spice of life"

                              This may only be of interest to those who want to stay at the very low
                              price range. Another point is that the hubs cylindrical projection has
                              a measurement (the ones I am buying) of 16mm. This is important
                              if you tool up say a fine tooth paneling saw blade because she fits
                              right on the hubs.

                              No machine shops and all of the big prices. Only for the poor boys club.

                              How are you doing over there Dave?

                              • Arduino and houses

                                Arduino and buying and selling a home have nothing in common.

                                Been trying to sell and buy a different home at same time. Painful. Therefore no time to build or test.

                                But still I'm studying/ buying Arduino to use to switch battery positions. Started out with basic setup to learn and grow with. The C++ language is a challenge. But the Arduino website is very helpful for beginners like me.

                                It only takes a small table area to setup and run different setups. Got the 8-channel 12v relay module yesterday. But its not as hugh or what I thought it to be. Not sure the relays can handle the marine size batteries I use on the 3BGS. I may need to connect them to larger more heavy duty relays for switching the batteries around.

                                Will see as I'm able(?) to do any real testing,
