IROCC End-Of-Season Barbecue

It would be great if you could prepare an entree for the herbavores (a vegetarian dish).  The club is buying, so feel free to ask for reasonable compensation.

We probably won't be able to make it now...Damn....

The main page voting isn't letting me do multiple votes either....

I have succesfully entered the dietary preference of me and my guest on the main-page poll, so I don't understand why you are having such problems.

And yes, I did register a whole number of guests (as opposed to a natural number of guests).

[Grinder]

Is it possibly because you have admin rights?  It would let me enter three then that was it - locked out.  Did one adult, two kids then it wouldn't let me do any more kids....

[Tom]

I only log on as admin when I'm doing admin things.  Try it again.  I'm amazed at how often people don't try things again. . .

There is a time limit to prevent flagrent abouse of the system that prevents more than a certain amount of activity within a certain time period; this is likely what caused it to stop for you.  So, wait a bit, and try again.

It does seem to attempt to enforce one vote per member in the forum polls however, so everyone could just create a bunch more accounts. . .

[haddow]

i am logged in as admin and i can only vote once. I only see results no option to vote again.

Funny normally we hate the fact that we cant stop people from voting numerous times in our other polls and now we bitch about the opposite. damn humans.

At least we know how to hold more "accurate" polls for other topics, post them in a forum thread instead of using the "polls and surveys" option. We could move this poll there and people can vote as much as they like.

That's exactly what I did!

Doesn't anybody read any more before posting?  Yeesh!

[haddow]

too many damn post today to stay current!! Who needs live chat working ?this is almost "live". I have seen over 15 poeple on line today at once including 10 guests at one point.

I am finding it hard to work today, please post less!! LOL

[Grinder]

What do you mean by post less?  Less text per reply?

Besides if you want to stay current you should be on the Electrician thread   (hahah very funny MF)

[haddow]

yes my goal today (while hard at work) {sicko} is to get as many threads off topic as possible.

Post less as in less threads..

OK here is an off topic question for kurk or Tom that I had that I should start an new thread for but wont becaue I am a true jack-ass.

If i charge some 1100 mAh NiMH cells (Ithink they are called KAN size?) like the ones in grinders NTC3 reciever) to full charge. and then leave them sitting at room temperature for 5 days how much capacity will they loose by just sitting there?

peace

[Tom]

IIRC, they're listed as initially loosing up to as much as 10% / day (c.f. NiCad at 2% / day), so poteintially they could be close to 50% capacity.

I'd say realistically they'd probably be more like 75% or so.

The rate is dependant on the temperature. I believe, and I also beleve these rates are supposed to be around room temperature as well.

I'm too lazy to look it up though.  I'm supposed to be working as well!

[haddow]

so poteintially they could be close to 50% capacity.

that explains the emergency landing today at lunch.

any idea how the Lithium Polymer ranks compared to NiMH and NiCD?

[limey]

li poly's have almost no cap leakage thats why you do use a trickle on those suckers.

[limey]

whoops 8O  

you DO-NOT trickle li poly's

that sure is a recipie for some fire.

it sure is hard to pay attendtion to my instructer with such a alive forum

[Grinder]

I believe KAN is a manufacture not the size.  They were very popular because they made a NiCD that would source a LOT of current esp for the size of their cells.  The GP1100 are 2/3A size (yes they do actually make an "A" size cell - just imagine a 2/3A but 1/3 bigger  They are an amazing little battery and able to source at least 30A.  Normally a NiMH of that size will not source a lot of current but again GP is always pushing the limits of what these cells can do.

Temp will determine the discharge of the cells when they are just sitting.  More importantly is the manufacture and most important the condition of the cells themself.  If you are loosing 50% of the charge in 5 days the cells have seen their day in the sun and its time to recycle them.  Typical self discharge is 1% per day for NiCD and 2-4% for NiMH.  These figures vary from cell size, age, manufacture, etc but it is a rough rule of thumb.  I suspect its not a linear discharge either.  Regardless it should give you a rough idea of what to expect.

Li-Poly have the lowest loss over time and some claim from 1% to 5% over a period of 30 days.  Much better than NiCD or NiMH.  Typically the problem with Li-Po is the charge rate of 1C which means it takes 1 hour to charge your cells however everyone seems to be pushing that too.  Be carefull when pushing Li-Po as the will burn fiercely - always use a thermal monitor and charge in a metal tray.  Li-Po also is much lighter so your power to weight ratio is much better with Li-Po.  They also keep the voltage higher under load which also means more power.
