Coil Trials
Thanks theremart ....some good info to take in . When you say you wrap the trigger wire last are you still keeping the same ohms and lengths in the wire (seems harder to balance out to me )i might be missing something though...

I found a drawing.
If I did not embed the picture in this post here is the link http://i246.photobucket.com/albums/g...JB-Circuit.jpg What I see in this drawing that I did not build into my SG is ... Ground , C1 ,C2 ,C3 ,W3 , and a battery ( I am using a power supply ) Dodeca |

Re: trigger wire

Ideally you want the ohms of all the power coils the same. What I have found helpful is to do what Erin does, is to go to a place outside that is flat and mark off a certain distance. Then make all of your power coils this length. I did not get this far, but I believe if I filled my coil all the way, then took this outside and unwrapped it, then simply double it back that would give me the length of coil that would fill the coil for a bifilar. I hope this helps.. |

Hi Mart, You might wanna try hitting those batteries with a higher amperage than 800 milliamps but be careful as the transistors will heat up so make sure you have heatsinks on them and I personally like a fan on them.I find that the batteries charge better if you hit them with higher amperage for a little while,Another words hit them for maybe 5 or 10 minutes at about 1.5 amps then let them return to 800 or even 500 milliamps for say 15 minutes and i think you'll notice the batteries tend to like this sort of charging.Hope that helps and I thought those batteries were 6 volt golf cart batteries?. -Gary Last edited by gmeat : 05-10-2008 at 10:28 PM.

RE: Golf Cart
Quote:
I am running them in sets of 2 (6V), so charging 6 of them at a time at 40V on the primary side... The RPMS at 4150..... Zzooooom.... I have normally just set it to the highest RPM, since I want a more ON time, and sharper spikes. I can't wait till I figure out how to use my scope.... I felt all of the transistors and they are cool to touch while it is running. Since I am running this 24/7 I don't want any other arrangement. Under my present setup, I am using an OLD analog power supply, it can't give me more than .8 AMP. but will consider your method when I start using batteries as my primary. Mart |

Scopeshot
Can anyone tell me what this scopeshot represents?
I stumbled across it while looking for the *spike* on my monopole. I'm interested in any and all information.Link; YouTube - H_wave anomaly I haven't the experience to figure out what is going on here. There is a description of how I got to the waveform with the video. Thanks all. Warren .. |

SSG update.
Today I am starting a new test with the battery swapper. I have 8 golf cart batteries and 4 deep cell batteries all hooked up in banks of 24V. I was very happy that I was able to increase my normal charge on my golf cart batteries up to 6.8V this is a big improvement from before. The deep charging I have done for days is paying off.
I am pulling on my 4 coil 6 transistor energizer 1.5 AMPs, will try to run this on each bank for 11 hours. |

Another Noob
Hi All, Amazing amount of info on this forum.
I have just built my first SSG two days ago.(pics attached) My coil has only 330 turns, but it seems to be working ok (wound the wrong way so its a south pole motor I guess). The rotor is from an old 5" floppy drive and the magnets are neo's . I have a vid of the setup here for those that are interested. YouTube - SSG Video 2 I have many q's but at the moment I would like to know if it is better to attain the fastest rpm, or the most rpm for the lowest draw off the primary batts. Cheers, P.S sorry about the massive photo. Last edited by dambit : 07-09-2008 at 04:52 PM. |

You can convert the photo to a smaller one with "Faststone Image Viewer" it is free and works great! ( simple right click on photo choose batch convert ) then lower the scale of the jpg quality. The goal can be what you want it to be But the best is to look for conditioned batteries. Batteries that charge up fast and give their charge slowly.Here is what I do for a conditioning process. I will leave the battery on the SSG for days till it reaches the top voltage. Then I will put a load with its c20 rating ( fancy term for 20% of its rating ) till I have went down to 12.5V for standard batteries, 5.5 for my golf cart batteries. Then I repeat, the process of charging them normally gets faster with time. Note this takes months to get up to a "supercharged" battery and you will loose if you use a conventional charge, or.... if you let the battery just sit. Goal number 1 for me is to get a conditioned battery, then after that you can optimize the energizer. Until the battery is conditioned, it will jump all over the place in voltage and you will be scratching your head thinking.... what did I do wrong on my energizer. This can be normal, the batteries often drop in voltage, then rise then drop until they stabilize with the new method of charging. Note on your neos to keep it about 1/2 inch away from the magnets, you will find that it will take less amps this way ( at least I did ). Many methods out there for tunning the SSG, mine is to watch the target batteries voltage, the question is, what I change, does it make it rise faster? I have found that leaving the batteries on the SSG for days has really helped my good batteries. The bad ones... well ehhh i don't spend the time on them anymore. Too many batteries out there for me to fight the ones that take months to bring back. |

I thought the point of the linderman motor is that it doesn't induce voltage in the coils |

How do we?

I was not being practice, just idealistic... Would be good to have the battery always charged with cold electricity.. But this would have to be engineered... |
