Greetings Freaks -

 

I'm running out! I use wire wrap wire to do ECB corrections. Wire is small enough to solder to TQFP smt pins. Insulation is not that great to strip; wish I could find my old wire wrap tool with the little notch that stripped the wire so nicely. 

 

My question is: what gauge wire and insulation is this? And, any sources in the US? Mouser has wire but I am not sure if it is the insulation or gauge I expect. And, they seem to like to sell in hundreds or thousands of feet for well more that $100USD. I've been working off a little spool that used to ride on top of the wrapping tool.

 

Thanks

Jim

Digikey have it. I think it is 30awg. I purchased a 200m roll of cheapy wirewrap wire (i think it was adafruit brand) but the insulation isn’t the usual tefzel.
Be sitting down when you see the price of a handwrap tool these days. They only used to be a couple of dollars at radioshack back in the day.

As I remember now, I think the insulation was called "Kynar". For tool, I am thinking of the little hand tool with a hex handle section in the middle and one end that was a wrapper and other end an unwrapper. Will check Jameco.

 

This is the tool I was remembering though the brand is different:

I use B-30-1000.  Beware that at least some of the spools I've purchased are more like 700', despite advertised as 1000'.

 

The wire wrap tool I use is an unbranded version of this one, for which I paid much less.  I can't remember where.  Pick your poison.

I've ended up buying about 10 spools of 9 colors (got a wrong color once) from eBay.   Enough to last me 1000 years. Search for Wire Wrap Wire AWG30.  Spools of 300 meters sometimes sell for about $5.  Some of the spools have 8-colors of wire all webbed together.

Thats a really good idea.  Never thought of Ebay, oddly enough.

I use #26 OK Industries in 100' spools,  Klein D257-4C to strip and cut. Strip is done by pinching insulation in V of cutters, pulling away. It can be done without nicking wire, might involve skill building.

It all starts with a mental vision.

I've been using wire cutters as described, above, but my fingernails are getting shot. Had forgotten about those nifty dispensers. 

 

Will Get!

The cheap WW wire I bought has some sort of inferior-feeling insulation on it, compared to the stuff I have with "real Kynar."  I haven't actually tested it to see if it has probelms (most likely: lower melting point and thus a tendency to shrink back from soldering, or maybe easier to nick), and for most of the applications I do now (board patching or wrapping a small number of posts from one 0.025in connector to another), but it might be something to keep an eye on if you're planning on doing "real wire wrapping."

Oh, I guy on the Arduino forums bought this recently, and hasn't complained:

 

Seems like an "interesting idea."

This is the stuff I got from digikey -

https://www.digikey.com/product-...

 

Here's the datasheet (cough!) -

https://media.digikey.com/pdf/Da...

 

 

$7.50 a roll of 200m (~600ft). This is the stuff with the soft insulation Westy refers to. Fine for doing little fixes and lashing things up. I needed to test some 200A current sensors, so I 3D printed up a former and used this wire to make a coil of a 200 turns. 1A in for 200A full scale. Job done!

It's a long time since I've seen a wire wrapped prototype. Many many years.

 

Then again, to me, the term "wire wrapping" means this:

Not sure of availability in USA but https://www.roadrunnerelectronic... - no need to strip just solder. Great for prototyping.

That wire looks like the flux is in the insulation, so you just solder it???.  What a good idea.

You have not witnessed the smell !!

You solder through the insulation but the fumes are pretty unpleasant.   (at least they were 40 years ago)

 

But the system works well.

I guess I would have to bring out my fume fan, which I never use.  I like the smell of rosin flux.  I like the 24g telephone wire that comes in a bunch of different colors with different color stripes for perfboard use, which is mostly what I do.  I bought 10 feet of 10 different colors of 30g single strand on eBay a couple of years ago for about $5, and am still using it.

That's my favorite.

 

When the Police and Fire Departments were doing some training at a large building that was soon to be demolished, I got about 10 feet of the 26 conductor (or whatever it is), cable from one of the telephone punch board closets.

 

I've now got enough wire to build my projects for the rest of my life!

I quite like the smell of most rosin fluxes.

 

The "enamel insulation" might have changed in 40 years.

It looks as if Mr Flippers and Mr Kartman have recent experience.

I have 30 feet of the 50 conductor (or whatever it is) cable I got from a friend, and one foot of 1000 conductor cable I posted a picture of here once and will never dip into.  I have enough of the stuff to last 100 lifetimes.  I started out using stranded wire for perfboard projects, but quickly learned single conductor is much better.  You can squeeze it flat if necessary and slide it in next to a pin, or just wrap it tightly around a pin before soldering.  For some reason I like to have a tight mechanical contact in addition to solder, so it always takes twice as long to build a board as it could, but my solder connections dont come apart.

Hey Doc, going further off topic, I had my 4th ERCP last week.  In addition to chronic back pain I get attacks of pancreatitis when the sludge my liver makes (lost my gall bladder about 20 years ago) gets into the pancreatic duct from the common bile duct.  Usually the attacks only last as long as 45mg of oral morphine, sometimes I need a second dose after 3 or 4 hours, but this time I had pancreatic pain for 5 days without much of a letup.  I was getting pretty frantic, and really sick of opiates.  My gastro doc got me in for an emergency ERCP.  They raked out a bunch of sludge from the common bile duct, and now I am good to go for a couple of weeks before it can start again.  The last 3 ERCPs lasted 2 weeks before I had another attack of pancreatic pain, but at least they are keeping the Sphincter of Oddi open.  I can go anywhere from 2 days to 6 months between bouts of pain, but you can believe I run for the Schedule II's when it starts.  I give it an 8 3/4 of the 1 to 10 pain scale.  Getting old is not for sissies.

Sorry to hear about that.

Wish I could do something to fix it for you.

 

I'm glad you have a GI Doc on board.

Next time you see him as him if they ever cut the sphincter muscle, or stent the lumen?

(I truly don't know if those are options or not, I just know that sometimes "we" slice sphincter muscles, and sometime we stent open narrow passages.)

 

I guess if your liver is making too thick of sludge, however, then perhaps those would not make a difference.

Hey JC,

They did a sphincterotomy the first ERCP, and ballooned it the second and third times, so it is always open.  This time they didn't need to balloon it because it was open.  No stents  There doesn't appear to be a common channel between the CBD and the PD, so the sludge gets in when it flows out of the CBD past the PD, and some gets in.  I've been going through this for 10 years with on and off pain, sometimes a year between episodes, and I have done a lot of research.  I am parting ways with my gastro doc.  He is a big shot at UCSF and director of their Liver-HIV center.  He told me to stop doing research on the web and just "Do as I say", which is not the sort of doctor I can live with.  I'm not stupid, and want to know the anatomy of my own body.  I had a nice chat with the doc that did the ERCP this time, and he cleared up a lot of stuff. 

 

When I was doing medical devices to repair AAA with a graft delivered via a catheter I helped design up the iliac arteries i interacted a lot of vascular surgeons with egos the size of Montana  I even saw a couple of open AAA repairs, and a bunch of endovascular cases using our catheter in the OR.  I think if I spend less time lying about reading my Kindle paperwhite I will be better off as gravity will not want to pull the sludge into the PD just below the CBD.  They took out my gall bladder the first time this happened and saw gall stones on CT, but I dont think it was from a stone but from sludge.  Now my CBD is 8mm in diameter because of having no gall bladder, so stuff moves down pretty slowly.  I'm changing to a more active life style, and hopefully that will help.

That, I think, will be very beneficial.

 

There are many surgeons with hyper-inflated egos...

I guess that applies to many types of physicians, and to many people in general, but the profession just seems to collect more than their fair share.

 

There are tons of Doc's in the San Francisco area.

There is nothing wrong with getting a second opinion, or just up and changing to a physician you can better get along with.

 

Take Care,

 

JC
