Some Copper ribbon wanted.
« on: March 13, 2011, 08:28:55 AM »
While I was taking apart a Microwave one day the core had flat copper
ribbon for one of the windings.....one thing in all of my scrounging, I usually
never do....I threw it away!  ( what will I ever need something like that for ?)

So .....anybody got some flat copper ribbon like from a microwave that they want
to sell me?

Norm,
Have a micro coil with braided copper about 1/8" wide, will that work?

No I don't think so....want to use it to connect Ni-Cad battery cells together.
I've been using flattened copper wire ...but it's kinda tedious after 2 or 3 ft. 
....painful too ....if you miss and hit your thumb  LOL !
   Ah well back to hammering copper .....until ??
Thanks for your reply...
How's the weather where you are ?.... nice day in Conneaut O....but suppose to get
just a little bit of snow in a couple of days.
 What's your latest project?
I've been working on LEDs but not too happy with results.....

Norm,
I forgot to let you know I looked through my microwave stuff.
No ribbon it in at all.
I don't recall ever seeing any in a microwave.
Might be less common than you'd expect?

Hi Norm,

good to hear you are still having fun with your projects. sometimes we have a win along with the losers. still beats wasting time with the tv or at the pub.

can i send you some samples of this pre-tinned tabbing and bus wire that we are using to solder up some pv cells? might be just what the doctor ordered..easy to work with, we can usually drag solder from one part of the ribbon to where we need it then leave it there with a little swirl motion, cool stuff!

kind regards, dave

Seemed to be trendy in some older heavy duty transformers... I've seen it in a microwave, and in the transformers for high current (>50A or so) power supplies as well.

Norm -

I'll keep an eye out. I might just have a few of those laying around somewhere.

If I ever get to digging the pile of crap that is underneath the house out, I'll yank it and let you know.

Norm,

 Weather here (north GA) has been 10-20f above normal for the last  month almost. Bought a ton of wood pellets in February thinking I might run out before warmer weather and still have most of it.

 What's your latest project?
[/quote]

 Still working on the F&P alternators, rewired one 2 coils in series but still having stalling problems with them into a 24 vdc bank. Was thinking about your exercise generator yesterday wondering if the F&P alt would be a good choice for that type of application. Takes hardly any rpms to light a cfl unmodified. Maybe hook one to the TV and if the kid wants to watch cartoons she'll have to pedal to do it.

 Good luck with the leds, read the lighting section this weekend and after all of ghurds comments think I'll stay away from them. Sounds like they could be an expensive learning curve. I tend to over amp stuff  ;D

I have hooked mine to a 20 amp/hr 12volt Ni-Cad pak., then to a small inverter to run a 24 watt CFL 110v.
casual pedaling can keep up with the battery.
I can put 5 watts/hrs into a 24 volt battery in about 6 minutes but usuall stretch it out to 10 minutes.
Too fast is tiring and too slow boring.....usually try to do about 5 watt/hrs.during a commercial.
There's a thought a small tv and she could get ahead on the battery during commercials and
rest during the cartoons?

  Yeah I'm kinda leaning toward CFL's myself.....
Single LEDs with IC are kinda nice tho' ....4 AA batteries runs one of Ghurds lanterns with such
a LED runs every night for about a week before needing the batteries recharged.
Don't know if he sells them anymore or not.....

I think I got the ribbon from a very old good well built micro-wave...
the 'Cadillac' of microwaves.....well like the old Cadillacs not the new Cadillacs
ugh those aren't luxury looking cars anymore....agreed ?

Norm,
One thing I've used that seems to work pretty well is tops or bottoms of cans.  The ones that seem to work best and seem to be the easiest to work with are from lighter gauge cans... The bottoms from many "paper tube" cans like the ones used for hot chocolate or cigarette tobacco can be cut with scissors and solder flows easily on them.

  Yes Zap....thanks for the tip, I'll keep an eye out for those kind of cans
being more aware......

Copper Flashing and a tin snips?

Just a thought.

They used to sell it in any real hardware store.

You can shear fine strips of copper fairly easily.  I rolled a ten foot long by half inch wide strip of 16 oz copper into a coil and it finished out to about a 3 inch diameter.  If a shear isn't handy then slitters work well, too.  The shear leaves a friendlier edge on it, but I'd never call it safe for handling.  Copper is known for its slices and dices of fingers.

If you have a craft store nearby, go looking for stained glass supplies.  They use a self adhesive copper ribbon to stick to the edges of the glass before soldering it all together.

that adhesive copper ribbon sounds interesting RP, have to take a look at that next trip to AC Moore. :)

Norm, be nice to the letter carrier today  ;D..curious to see how you make out with the ribbon and wonder if you will be as impressed with that flux pen as i was. after a short time with that kester pen i asked myself  "where has this been all this time"?

have fun!
cheers, dave

Dave, Just got the stuff in the mail....wife says, "who's this from"
and I say....."Oh wow already?.....that was fast! "

  Thanks a lot.....I'm impressed.
   Been looking for stuff exactly like this for a long time.
  I'll be trying this out later on this afternoon....30 more watt/hrs to go
on the PedGen first.

  Then as soon as I get a couple of NiCad '6vsticks' disassembled and reconfigured.....
I'll let you know......
