GPSL 2015 that Mike helped organize was a wonderful event.   It was my first (and so far only) GPSL event and Mike was very kind to me and made me feel very welcome to be included in the group.  I’m very sorry to hear of his passing.  God’s comfort to all who grieve his passing.

Wow.  Such a shock to lose Mike so soon.  Enjoyed the GPSL he hosted and will miss him at future balloon events.  
My thoughts are with Mike's family and friends.

I was thinking I would launch a balloon in his memory after Covid-19 is less of a problem.

I'm sure many of you remember Mike. If you do and had the pleasure to work with him, could you contact me offline. Thank you


Re: Looking for groups that plan to launch at GPSL 2020

I of course, predictably, would like some form of live broadcast and after-event-posted video recording of a Friday session, even if its usual scope has to be limited in depth and/or duration.

Subject: [GPSL] Looking for groups that plan to launch at GPSL 2020

I would like to assemble a list of those who are planning to launch a balloon at this year's GPSL in Omaha if we can have an in-person event.  My concern at the moment is that even if we are able to have an in-person GPSL this year, so many may have work or financial impacts that we don't have a sufficient group to make it worthwhile.

If you or your group are planning to attend GPSL this year and fly a balloon, please send your email address (one person per group that's flying) to n9xtn@....  

Also, if your group is a regular attendee and you know for sure you will *not* be coming if we have an in-person event, I'd like to know that also.

I fear that with the purchase of a new home (which needs 170 years worth of repairs) and the pandemic that we'll be staying home this year.  I hope to put together a payload and simulcast a launch to be there in spirit.

Helium becomes more rare due to collapse of oil market

I thought this article on shrinking helium supplies might be of general interest to the group.  It is written by a professor of out of Durham University in the UK.  Here is the link:

Minor GPSL 2020 update

Mark Conner N9XTN
 

I checked with UNO on the status of their summer events.  At the moment, they have cancelled all campus events through June 30 (GPSL session at UNO is July 10).  The person I'm working with does not know when they will decide about July events.

I'm also aware that some may have difficulty traveling to GPSL this summer because of job situations.  That will also be factored into the in-person vs virtual decision - if we don't have a critical mass that can come in person and launch, it may not make sense to have it in person.

Joe,

The graph that you have shared has the horizontal axis in units of Ah (Ampere*hours) not in hours.  It is fine.

This means that all current draws are about 7.5 Amp hours with the smaller draws performing better than the large draw.

I am very confused on a battery pack.

Say you have a pack that can run 1 amp of current draw for 10 hours.
One would think that if you only drew 0.5 amps that it should run for 20 hours or close to it true?

Now many of you old timers here will remember these awesome surplus packs that looked like this.

These things were OLD like 20 years old when we used them yet the power they could provide was incredible!
They were rated at 7500mah, incredible! Sadly this supply of "NOS" dried up and new packs were very prohibitive in prices. Easily ending up being like $100 bucks a flight!

But I found a source for Brand new ones, that would make it like $15 to $30 bucks a flight! YES!

But it's performance curve makes absolutely no sense to me!

This makes zero sense at all. I can draw 2 amps  or 0.25 amps and it changes the lasting run time by only like 15 minutes?

That doesn't make any sense!

Re: Payload Power Sources

Run time to a 24 volt cutoff because the effects on the capacity are clearer.

On the closeup graph view C1, C2 and C3 are the capacities for 2 amps, 1 amp, and .5 amp and lower.  That means at this cutoff voltage the ultimate capacity is reached at .5 amp and anything less for current drain does not lead to a higher A-H capacity.

C1(2)  is ~ 7.0   A-H  
C2(1)  is ~ 7.35  A-H       5.0% increase with respect to 2 amp capacity
C3(.5) is ~ 7.6   A-H       8.6% increase with respect to 2 amp capacity 

So runtime for 2 amps drain is 7/2 = 3.5 hours.

The other runtimes for 1 amp and .5 amp are 7.35 and 15.2 hours.

I've left off some of the units in the equation for 2 amps but as a check A-H divided by amps gives a result in hours so the units are dimensionally valid.
