The thickness of wire in the coils ha s not actually been specified[unless someone knows better.] and so may not be critical.

I remember a number of 2.5.

I don't remember if it was 2.5 mm² or 2.5 mm diameter of the wire (but most likely: 2.5 mm²).

Hi,

in German, we are using mm? for cable diameters.

btw. how are the cabels connected to the graphid sticks ?

Best regards,

atlantex

I have not yet connected my cables to the graphite. The problem is that graphite breaks easily. This is my plan. Do not connect coil wire directly to graphite. Use a short piece of flexible cable which is made of many thin wires.remove insulation for 20mm at the end. Spread out the thin wires around the end of the graphite stick , and bind them with many turns of cotton or nylon thread. Now join the flexible cable to the coil wire with solder. that is my plan.

If you use these welding electrodes which have graphite inside (and copper outside) you can leave the copper at the end of the electrode (and remove the rest of the copper). You can then solder any cable to this copper.

But i didn`t find any source for this electrodes yet. Even stores who sell welding supplies don't have them.

Here is such an electrode, but it's far too thick for our purpose: Click me

For graphic rods you can get them at hobby store, they use them in R/C planes. They have all sizes. don't know if its the right stuff but easy to get.

Here is how I did it:

1. Split carpenters pencil to get the the graphite rod
2. wrap with thin copper or brass sheet
3. solder the whole thing together

wrap is extended a bit from the edge of the rod and wire goes inside the wrap.
Hope this helps.

It's definitely NOT the right stuff. What you mean is carbon fibre rods, they consist of carbon fibres laminated together with epoxy resin.
They are not electrically conductive, so they most likely won't work for our purpose.

Hello georgemay,

looks really good but I think to remember that Thomas said in one of his postings that graphit sticks from
pencils are not the right choice... may be I'm wrong but I'm quite sure.

What's happen to the user hurricane? His device is already working as I could read.

Best Regards,

Graphitst?be / Graphite Rods

Wer Graphitst?be nicht selbst auf den notwendigen Durchmesser abdrehen will, der kann diese auch passend kaufen. Es sind dies Teile f?r die Funkenerosion und Drucksintertechnik. Ich habe hier ein paar deutsche Seiten beigef?gt, welche Graphitst?be (Rundlinge) verkaufen.

If you don't want to turn a graphite rod you can buy them with suitable diameter as parts for spark erosion and high-pressure sintering. Enclosed you find a few german sites selling graphite rods.

Bleistiftminen haben nicht die notwendigen technischen Eigenschaften, wie Thomas erkl?rte. Sie bestehen aus einem Gemisch von Ton und Graphit.

Leads for pencils don't have the correct technical properties as Thomas stated. Pencils use a marking core made of powdered, refined graphite mixed with clay.

@Pontifex:

Danke f?r die Links

Einer ist sogar bei mir in der N?he, da werde ich mal fragen.

I seem to remember Thomas made comments about the correct graphite rods to use, but i can not remember exactly what he said. [ its my age] seem to think he said carbon rods from batteries would work, but it would be hard to find these in the right proportions.

Hi Pontifex,
I know... Thomas said a lot of things.... Some of them didn't turn out to be true. We have no idea if even v6 is complete...

And I did a test on the pencil lead. I put it into a ground and I got over 1.1VDC well - almost 1.2VDC when connected to the bolt in the ground. I hope in the sand with salt water won't be a problem.

"The carbon rods from batteries" was an unanswered suggestion from Stefan Hartmann. Thomas said he used rods he bought from Bosch but they were too thick and he said that it was a very dirty job to turn them to a smaller diameter. It seems as if these rods were "carbons" for the connection of the collector for electrical motors (Schleifkohle/Kohlestift).

Any examples for such a statement (besides the release of info announced for today) ??

Hello Group
When i join the First thing I did was to copy and save everything i could relating to the project. I do not trust the internet or a groups files any more. I have pretty much everything i believe. The last time Thomas was discussing the tech the same thing happened due to him getting pissed off and left the discussion hanging. I did my first replication a year ago with out much success due to lack of construction data and procedures. This time when i had the chance to gather more data, i save everything i could relating. So that being said, some maybe helpful to workers and some me just be redundant, but i offer it all to the group if the group wants it. Tell me where and how u want it and i will try to get it to U. Even private mailing would be OK, just time consuming. Some of the stuff will need to be complied into a doc of some sort, but workable.

Regards
Bill
