Power Meter Calibration and Comparison

Haha, yeah, they will get hot with high currents. I've had them running 420mA for >20min. on the "RED" setting and they would be hot, but they held up just fine, I'm still running the same test load since I first made them.

Anyway, the only thing to keep in mind if I do the heatsink is that it will need to be isolated from ground, which means it should not touch the housing if it is grounded.

Sorry I overcaculated the fee's for paypal.  Payment needed is only $10.35

I'm sending my $15 bucks right now Kenom...

Just taking the lead in a little extra contribution for your efforts. Hopefully others can add a little too!

How about the form to send with the test kit? Columns for listing different meters, etc... Maybe have a space at the end for tester notes. Should some kind of viewable data sheet be set up in this thread as well as a hard copy to send with the kit?

Not a bad idea.  I think it would be easier to just use a jump drive with an excel spreadsheet.  I can pick up a 128mb one for $2.99 I think it's safe to assume that we all have computers (hehehehe else you wouldn't be postin here!!) and hopefully excel as well.

I have excel, not sure if everybody else does... Just not sure what a jump drive is.

Peace,

And, Kenom, will you be mounting the driver centered in the housing cavity or resting against one side? If it's against one side, I could leave the fins of the heatsink a little longer. It would look similar to this:

I do, have Excel Jayrob!   Also anybody using Google can save an Excel spreadsheet as a "Google Doc" they are easy to use if you don't have Excel and all folks can use them free. I ran into them doing a GB list to LG recently.

I was thinking about an excel sheet too, but not everyone always has excel. We could redirect people without excel to openoffice.org, but still, they need to be willing to install it.

I suggest everyone posts what he has, and let's combine this with other needed stuff altogether.

Every participant post this information:

• Your country (for shipping redirections)
• What kind of high powered RED and VIOLET lasers do you have (remember, this is a requirement to participate)
• Do you have a program capable of editing Excel files?

As for me:

• The Netherlands
• See my sig
• Yes

Another question. I might have missed something here. Is everyone donating $10 so they become co-author of the lasers or something? I previously suggested that everyone pays the full price to the previous person in the chain and the last person is paid by the first, Someone even agreed with that. So effectively everyone only pays the S&H costs because they both pay and receive the laser price. I can see the disadvantages of this. Not everyone might have $140 lying around, and the paypal fees will also increase a lot. Am I right in expecting that the laser price will be returned some time after the participation, or is it seen as a donation to Kenom (for what reason?) In either case, I would not skip this if I can calibrate my meter for $10.

Everyone is just paying the 10.ish to Kenom. A combined effort for the cost in parts. (what a deal!) I personally think Kenom should get a little extra, maybe rkcstr too. I sent a little extra.

Plus, every contributor pays the shipping to the next person on the list of paying persons. Other than that, all that each participant needs is a meter (or more than one). Because the same lasers will be used...

U.S.
I have Excel

On that note... I'm not too sure how this is working either.  Will I be paying as well, or is my contribution factored in as my "payment"?

In response to Zom-B's info request:

1.  US
2. both red and violet
3. yes

BTW, Google Docs can also handle excel files, except for graphs (and maybe other advanced features), and you just have to upload it to their site.  Also, the excel file can be set to be shared and edited by anyone, sort of like a "wiki-excel"  ;D

example, my drivers output settings sheet, you can edit the values and what not to your desire (but please change it back, lol!):

As far as the payment goes.  Jayrob is correct.  We all pay for a portion of the cost to build the laser and then to ship it on to the next person when we have the laser in hand.  I was actually thinking it would be better for the person to pay for shipping TO them not to the next person cause if say, I ship the laser to jayrob, and he then has to ship the laser to Igort, Jayrob will end up paying upwards of twice what I would have had to pay to ship the laser to him, and that just isn't fair.  However, if Jayrob pays for the shipping then igor will pay the actual shipping cost back to jayrob.  yes, it's more in the long run for paypal fee's but all in all your only paying $1 for paypal fees or less.  

Lets hear what everyone thinks.

rckstr, I was planning on putting one side against the side of the barrel, so you could leave the heatsink larger.

As far as what happens to the lasers after the experiment and such is done, I'm thinking the lasers could then become forum property and all a person has to do, to get access to it is, 1. have the requisite lasers and 2. pay for shipping to them.  We will then always have these lasers sitting around waiting to be used in the event they are needed.  However if after a certain time, the lasers are not being utilized, they can be resold and the funds redistributed back to the original contributors EVEN IF IT'S AN INCREASE.  So say it's costing us roughly $140 to build these lasers.  We turn around and sell the lasers on B/S/T for $250-$350.  The sale price would then get broken up to into 14 ways and each person would get 1/14th of the sale price.

rkcstr, hey that Google set up just might be the ticket! Would you be able to set up a similar table with columns for User Name, Meter, Red Reading, Blu-ray Reading, Conditions, Notes, etc...

Would it be something that each person can edit their new information into? And everybody can then see the added information?

Also, not sure how Kenom set up the breakdown, but he probably counted your contribution of the drivers and stuff as your share...
Jay

About shipping... In the U.S. 'go round', depending on total weight, it would probably be about $10 bucks with insurance.

Now when the last U.S. participant needs to ship to IgorT, he will have to ship First Class International with no insurance (about $10 bucks). Otherwise, it will be expensive. Also, mark as a gift, with a description of LED flashlight, and a low value, like $20 bucks...

Kenom, payment sent please check me off on the list.

I know I brought this up already but, we are going to send this in an orderly fashion right? This will be much quicker rather then going from one coast and back again to the next person who might be within the state. So we need names plus sign on and address so we can figure out the best shipping order. I can put this together if you want to pm me with your information. After compiling the list I can post the order (sign on) and pm the name and address information to the people on the list.

Yes it would be more beneficial to send to others pretty close to yourself first.  I've got the shipping information from all the payments and was going to use that to make a travel itenerary(spelling) to expidite the laser getting to the next person. so make sure your shipping information is accurate.

Jay, yes indeed I had counted rckstr's work as payment.  so it's not necessary for him to pay that portion.  Your not the only one that has paid a little extra so even had I not counted that, we have enough to cover his portion.

I also LOVE the google docs idea. it's the perfect solution.

Definitely orderly! PayPal information should have addresses in there for most...
Jay

(typing at the same time again) All sounds good Kenom!

kenom, you will take care of the shipping order then? Thanks!
