Brian, did you gae some files? If not let me know and I can send you some.

Any one know the optimum setting for this? What is the possable ranges and what exactally does it do?


Benny that pic looks great.

I was thinking about winding coils also, I need to wind some solenoids. It seems to me that a wizzard for lathe would make more sence. If you think about it laying down coils is a lot like cutting threads.
If you added a spool diameter and had a lookup table you could also calculate coil resistance based on the wire diameter and calculate how many feet were going to be used. You would also need to know the bare copper wire OD and the wire with the insulator OD.  for example I looked up a 24 gauge wire..


DCR based on resistivity of 10.371 ohms per circular mil foot @ 20°C ( 100%IACS Conductivity)
AWG    Bare Min.    Bare Nom.    Bare Max.    DCR Min.    DCR Nom.    DCR Max.    cmils    feet per lb
24       0.0199       0.0201        0.0203        25.17         25.67            26.19              404     818

Values listed below are derived from the NEMA MW1000-1997 Standard or MWS Wire Industries internal inspection criteria
Insulation Build    Insulated Min.    Insulated Nom.    Insulated Max.    Film Increase Min.    Feet per LB.
Single                       0.0209         0.0213           0.0217             0.0010               804.5
Heavy                      0.0218        0.0223          0.0227            0.0019                      790.5
Triple                        0.0228          0.0233            0.0238              0.0029                776.5
Quad                      0.0234        0.0242          0.0250              .0035               762.5

As you can see the diff between the single insulated and the quad is 42 feet per LB, or 435.582 ohms.
It would be great to calculate impedance, however this becomes difficult because of the difference of the bobbin and the frequency.

Any how just some food for thought..


General Mach Discussion / A little praise, and comments on the new site.

Hi all,

Ynneb, First I would like to say great job. The web site is looking great! Thanks so much for the forum work! (I hate Yahoo groups).
Art and others, Simply amazing software, thank you all.

That being said, a couple of comments about the site. Forums are great, wiki's are great, gallery is great. The only bummer is all the passwords and user names for all of them.
You have implemented lots of great features as standalone items, at the cost of a single user name / pw.
If I might be so bold as to make a suggestion, I would recommend that you take a look at a CMS system to tie all of this together under one roof. I have used in the past PHP-Nuke, and in my opinion it is exactly what you need. It has all of the features you have implemented as separates rolled into one. It is simpler to manage and has the added benefit of a common login and password. You already have PHP and My-SQL working and that is the toughest part. With nuke you can get "blocks" and add ons for just about everything you could want. Upload, download, gallery, chat, wiki, forums, mail, vote, feedback, newsletters and about a zillion others, all for free or little money. You can also strip it down to just what you want or need.

Any way, just a suggestion.

here are some links of you want to learn a little more

PHP-Nuke: This is the main site, this is the download for the core.
Nukefiles: This is a great site with a TON of blocks and plugins, and a great idiots guide to nuke.


It is a huge comunity and thousands of websites are running it.
