The 3d Monopole Coil How To Build

[ZPDM]

The small one,
This is by far the smallest one I have done yet. This was a real pain to do since I had to hold the coils to wind them. I also had to file the rotor and some parts. Think I’m going to re-draw rotor with slots to slip in magnets as they are about 5 mm X 1.5mm. Coils 650 turns #40 wires the printer seems be able to print this just fine. The energizer is about 64 mm in diameter. Will post when it is running.

Many thanks for the update John. One thing that is certainly being confirmed is that, at least in the right hands, by this point a 3D printer is a pretty useful fabrication tool. Looking forward to hearing about how it runs.

Patrick,

in place of the Caps on each diode, add a battery in a muilty SSG style circuit, so that you are charging several batterys from the same primary, 1 off of each diode. this would act like my 5 for 1 solid state version muilty SSG style circuit that was destroyed in the fire.....

RS

ps, 2 AAA rechargeable or 2 AA rechargeable in series for each diode should work for the batteries in this size energizer circuit....

here is the latest version of the rotor we are working on. it is larger than the EZ spin and as such it will be easier to work on. we are working to make it easy to source all of the parts locally, or we will sell them together as part of the kit. looks like we will be doing this in either ABS or PLA, depends upon how we can source filament at a good price.

Hey all, Just found this thread from Aaron's newletter (still waiting on the conference video of Graham Gunderson Aaron...) I have been following John for well over a decade and excited to see an open source project with his backing. I have a 3D printer and I'm proficient in SolidWorks. Holler if I can be of any help. I will happily print and mail anything to anyone if you cover the cost of postage and plastic. I have great success with PLA but ABS does not stick to my bed well. (I need some kapton tape). Is anyone publishing STL's yet?

Hi JB

Looking forward to the new SCR Tracker.....

Look for a email with 1 hour of yesterdays real time Solar data.....

Still waiting on my 3D printer to come in, Gurrrrrrrr.......

Mean while, I have been working on several more 3D things to print, when it finely gets here.......

Looking at the DesignSpark Software now, I have been using FreeCad and it is way better than 123DCad

Hi, welcome! Graham's presentations are available through: http://grahamgunderson.com/ou

Hi everyone! Been away from the forum for a while and found this thread linked up on TeslaGenX. Really exciting stuff! Enjoying watching the progress. Thinking there may be a 3d printer in my future.......

We are moving along here, the latest version of the 8 pole back charges the primary. you can place a dead alkaline on the machine and it will charge back up. still working on the bearings for the kit.

Awesome! No pics? Arrrrrghhh!

Now that's what i'm taking about - nice!

this is a scope shot off the motor you can see the square wave is the reed and the coil firing, the sine wave is the backcharge from the coils.

[Tom C]

here is a pic of the motor the stator is 6 inches in diameter, the total coil resistance is 11K ohms.

I am using this machine to hand wind my coils. its too small for an SG coil but works really well for small coils. it has a pulley on it so you can find an old sewing machine motor and make it electric. the counting feature is needed for this build.
