hey guys! better late than never... called and emailed the guy about the cores today, the guy must have been out... i will try again tomorrow. i'm still on top of it. ill keep you posted!

Hi,

This is my Simple DIY Coilwinder I use for winding the VIC coils.

It is based on the RepRap Sanguinololu v1.3 circuit to drive the Extruder Stepper.
Firmware is based on Sprinter.

I made a few hacks in the firmware to read a pot resistor and two switches for direction, power and speed.

Stepper speed regulation is not accurate on high speed, feel free to update this firmware. Let me know if you solved this!
(but you will not run this at high speed winding this type of coils) :cool:

NOTE. do not use this firmware for your RepRap 3D printer.

Firmware attached!

That's very cool webmug, I wonder if it would work with the arduino Uno and a Pololu A4988 Stepper Driver.:D

Hi Jeff,

Firmware is for ATmega644P, this version wouldn't work for a ATmega328p controller. But if you can find/make software for ATMEGA running a Pololu A4988 Stepper Driver, let me know. Got also a ATmega328p board.

But I needed a "simple" DIY winder configuration so a got this as a result. Can be much simpler :D without the RepRap functions embedded in the firmware etc. :D

I wonder if floaty boaty could help with this, he is really good with software. He could possibly even just write a program to control the speed and count the turns [opto] as it's winding, maybe even run a display for speed and count. To do the count we could use one end of the square bobbin to pass through the opto as it turns, make the opto adjustable for different size bobbins, as well, that would really be cool.:D:cool::P

Hi,

I finished the VIC coil windings on the bobbins.
Unfortunate the secondary (2700wnd) has not enough windings so the resistance is too low. So I have to unwind it for next update. Feedback coil has center-tapped coil.

Russ, did you center-tapped the feedback. (400wnd, then extra wire, 400wnd) total of 800 wnd?

Chokes have to many windings. (3100wnd) I'm waiting for the core to arrive so I can adjust for exact values.

Yes, got a analog counter :D
Counting the windings should give an indication, but we need to know the resistance. So counting the wire feed length should be better.

The VIC coil looks excellent! :cool: So you wound the coils with your new stepper winder?  

Yes,
wound it with my simple DY coil winder.Got a analog counter attached :D

lets start a new AUTO COIL WINDER THREAD under the open source projects as that is a grate place for others to find it as this is going to be a very sweet build!!!

looking forward to it! :)

My feedback coil measurements are:
FB1: 9.0ohms; 400wnd; 2.67mH
FB2: 12.1ohms; 400wnd; 4.30mH

Not bifilar, but as one coil but center-tapped.
What is the difference winding bifilar for feedback coil, should be tested.
One thing I know is that you have the same resistance with bifilar. :cool:

yes, and look at the data from the estate and the data i collected... :)

The reason why I ask is that you got two tables with data in:
"VIC_Readings RWG Forms 4-14-12.xls"
Building Notes said Bifilar, correct!

But number of turns "?" and bottom table resistances FB1 and FB2 are different.

Thanks!

I did it both ways, when I wraped the bifilar I did not mesure the turns... Lol just went with it till it was full then unwrapped some...

But yes. I finalized mine with bifilar.

Thanks!

How high is the voltage from the chokes?

If we look at the connection terminals, they are rubber insulated from the ALU box.
There is a spark at 3kV/mm in air.

Good info and post, Jeff.:D

Russ,

Good to see your videos showing that you got the cores in.....And those original injector drawings, Awesome......I have tried very hard to get a hold of those but never had any luck, so thank you.

I think we're all going to be in a bind trying to get the 5 coil VIC working.....When Don had them in his posession he could hit resonance but he said they never produced any gas. (To me it seems like the actual coil design is the issue.)

In the Injector VIC drawing there is a part number for the electrical steel which I am emailing the company about....Hope people out there start building and selling injector parts, Since we have exact specs it might be a better avenue....

[attachment=1483]

Ready for the VIC core, just in time.....Lets all just keep our fingers crossed!

good stuff guys!

i sent out all but sharky's and webmug's... this over seeas stuff sucks! lol

everyone should have them either by friday or tuesday... please send me a PM to let me know you got them!

the cores and ECT that is...

keep up the good work guys! ~Russ

I have found a cnc guy who can route alloy out he only does
simply blocks  similar to housing  ,

 so if we have a foam or ply mould
to make sample for sketup we can get housing samples made.

Dan

Im about half way done with the VIC box sketchup.  Need to start the cover next.

[attachment=1509]

I'm 99% sure on most of the measurements.  The measurements in the Z axis are hard to pull from the photos.  All the important measurments are good though.
