A few newbie questions.

Yes Konstantin, I am guessing that any non ferrous non magnetic coating would do as it acts as a magnetic isolating barrier. The eddy currents are contained within each rod, but it is still electrically conductive. You could coat your mild steel rods in gold and it should do the same thing. Just cost a bit more

[kingstingtin]

No, gold this is too much
Today I asked with predilection the seller KEMPPI about of this rods. He told me that he never such rods are not provided.
But now I know that such TIG and MIG welding.

K,

RG stands for Rod,Gas welding. this is a mild steel copper coated welding rod for oxy-acetylene gas welding tell your welding supply house you want oxy acetelyne gas welding rod mild steel, they will have something that will work. if you cannot find it copper coated, get the rod uncoated, let it rust a bit outside till there is a coating of rust on it. then wipe off the rod so it is smooth but rusty.

Thanks Tom for the link. Today I rang them on the phone.
This factory produces only the electrodes and fluxes for electric welding.
And to me, as I understood, need filler rod for TIG and MIG welding. Or am I again that that not that looking for?

Hi everybody!
I have finally did what had to do long ago. Recently, I all the same bought a gel battery to 18 Ah to power the device.
Today I analyzed three cycles of charge, using the battery as a power source. And found a few interesting things.
My digital multimeter (Fluke) shows the current consumption device 350 mA.
Device operating time of about 101,000 seconds.
Based upon what Excel calculates the energy consumed about 10 Ah.
But after disconnecting the supply battery, voltage on it is about 12.4 V.
Which means that it still had 75% of their energy!
18 Ah - 75% = 4.5 Ah
So in fact, the device is used only about 4.5 Ah.
And actually the current will be about 160mA.
Maybe my device working as it should, but a multimeter is lying?
I need the resistance of 1 ohm 5 watts to test it.

Today purchased infrared thermometer. And made measurements of temperature.
Ambient temperature is 24.5 C.
Temperature of the secondary battery 24.5 C.
Coil temperature 27.5 C.
Is this normal? Or coil temperature must be exactly the same as the temperature of the environment?

[kingstingtin]

No comments?
At the end of the charge, the temperature of the secondary battery has risen by one degree Celso.

[kingstingtin]

Maybe I need to stop charging when the battery is just starting to warm up? Where are all gone?

[James Milner]

Konstantin, we are still here.
I'm wondering if your core of transformer steel is heating up with eddy currents and being transmitted to the coil by thermal conduction. I trust that will disappear with some copper coated welding rod. I hope it arrives soon!

Konstantin,

Sheez, 25 pages, just get it done and say thank you already. I used to think Russians were so smart with Bedini's help a ten year old American girl built one, what's up? If you are confused just contact Alexander Frolov Ïåðñîíàëüíàÿ ñòðàíèöà Ôðîëîâ Àëåêñàíäð Âëàäèìèðîâè÷ Web page Alexander V. Frolov he can translate and explain for you.

hello i am from Netherlands sory for my english
i have 105Ah battery how can I count the magnet wire I need to make a Bedini 24 inch wheel and how many magnets?
thank you

[ZPDM]

Ed,

The magnet wire, when counted, must only be prime, shhh or the masons hear. The magnets are in the golden ratio of the diameter. From the "hinterlands", you're welcome.

[kingstingtin]

Thank you, James, for the answer.
I also hope that the copper coating will change the situation for the better.
This means that the coil has to be exactly the same temperature as the environment.
I hope that did not ruined the battery yet another, and I'll wait for your parcel.
During the first four cycles, the battery capacity confidently increased.
In the end, it reached about 130% of its original capacity.
But then, the capacity started to decrease again.
Charging time continues to decline.

[Ed_Morbus]

Thank you.
have you more information how match feet magnet wire size

[lis_wang]

And hello again to all.
I finished a cycle of 20 charges / discharges. I know that these cycles do not correct. But still send their table.[ATTACH]716[/ATTACH] Battery is old, and I have not received the proper result.
Now I bought a new battery and decided to rewind the coil. Because the wires were not tight enough are. This time, I decided to interweave the wires together. [ATTACH=CONFIG]717[/ATTACH]
And a little bit improved bottom coil. Made there way out for the wires.
[ATTACH=CONFIG]718[/ATTACH][ATTACH=CONFIG]719[/ATTACH]
I hope that this will make my device work better.

Hi, kingstingtin

How did you discharge your battery? Did you just connect a resistor to the battery and then measure the current and time of discharging?

Thanks for your reply
