It is a beta version, so no fancy userinterface / print options / export /

I would also like to beta-test the software, please.
Thank you.

I received your beta version and the update to it. I experienced the
timing out that the update was issued to correct. The updated version
will not connect, or cannot detect the Zelocity PureLaunch monitor. I
can use the Launch monitor without difficulty and open your software
after getting the Zelocity software up and running. This was the
order that was described as being required to launch the software
programs.
Thanks and hope that this might provide you with some information that
you may need.
Best regards,
Frank Hann

I copied that part of your message that I do not understand.
If you have the zelocity software running it will use (block) the
connection to the PL unit so NO other software can then connect, it's
like a telephone. The line is already busy,
The only thing you need to do is connect the PL unit to the pc and
turn the power on, that's all. The pc will then recognise the PL unit
and create a connection for any software to use. Then start the beta
and you will be ready to go and test :-)

PS Please use the email address from which you received the beta
download link. I login to that account almost every 10 min. The gmail
account maybe every 3 days :-)

Hi Frans:
Thank you for explaining how to properly use your software. I will check it out tomorrow morning before my client comes over to hit golf balls at my indoor ball striking facility that I have set up in my garage for this winter.
I will keep you posted on my results.
Best regards,
Frank Hann

Received message that still one beta-tester has trouble connecting the
PureLaunch. Will rewrite the test software too see if that can be
solved.

Hello everyone,
I am a new member and old owner of a Purelaunch. Like many of you, I
was quickly disappointed by the unit as I realized most of the numbers
were fake. Of course, I couldn't get a refund and the fact that I live
in France (I'm French by the way) made it all the easier for Mr Starr.
4 years later, I decided to give the unit a second try and here I find
this group. It appears I'm not alone and, more importantly, it appears
there's a solution in the process.
Needless to say, I'd very much like to be a beta tester and share my
input.

Frans, could you send me a link to your beta PL software or post a link to it?
just around May10th.
Did you do any more work on trying to create any of the calculated results
given the user specified static loft.

Some thoughts from a PL 5.2 user.
I have installed and latest beta code from Frans and really like the detailed chs vs time plot as well as the count down feature for the arm time. Thanks Frans.
Given accurate chs vs time one might be able to make technique changes to increase chs at impact with this data.
As for the arm count down: We all know how many "good swings" clients have made just after the arm light went out. So Frans's arm count down is really helpful.
I did check the beta software reported LA value after using a laser pen to check where the PL base was pointing, then I measured
the height of the hit on the net minus the tee up height of the center of the ball and then calculate
LA = tan(ball gain in height/ 144"). The result was within 1/2 degree. Trackman spec for LA is + - 0.2 deg
I have a casio EX-F1 so I hope to help Frans check chs vs time, bs, and could calculate Azmith given a net hit point and some trig calculation. Club Face angle could be captured vs time as well with a camera in the swing plane pointing down at the ball.
Would have to deal with camera distortion with some calculations to remove line scan skew. reference:
http://www.tutelman.com/golf/measure/focalPlaneDistortion.php
Could also put the camera at a few inches above ground level and aim at the ball/club head and get AoA and DL (messy due to scan line distortion) Key is these could be plotted vs time instead of just having 1 value at impact that you get from Trackman or other LMonitors. It would really be nice to know how fast a players hands are rotating through impact and when the hands
try to hold the face square and how much of this rotation change effects chs in the last few msec before impact.
All of these camera measurements would required software to manually digitize the video or some auto tracking software.
The also suffer from the low sample rate and digitizing error. For example Trackman staff says that AoA and the Club path can can change by .8 deg while the ball is in contact the the club face. Trackman spec is + - .5 deg for AoA and CPath or Horizontal angle. Another interesting number from Trackman research team analysis is that the Dynamic loft and face angle can change by 1 deg through impact. Dave Tutelman says that the gear effect result that people once used in analysis was under estimated and future programs like Trajectoware will take the new data into account.
By using using Vernier http://www.vernier.com/soft/lp.html I was able to plot items like AoA and I think 1 deg accuracy
is most likely best case for the Casio setup given manual digitizing noise.
I also have tested the freeware Kinovea video analysis tool. http://www.kinovea.org/en/ . I use v1home premium http://www.v1golfacademy.com/ but v1home only allows static measurement of angles and annotation.
One also needs to have reference lines in the video image to set the horizon line and target line as needed.
I wish the PL had a way to auto level and maybe a sighting device for the target line. I use a laser pen in my garage
for checking horizontal level but would like a user input control to set the PL target line given slight miss alignments
of the unit or the sensors. Trackmans auto leveling and build in camera to get the target line are what one really needs.
So what key measured values are missing: Spin axis and spin value. Maybe possible with a camera shooting down the target
line but I have never tried it with a marked ball. One would have to deal with 3d correction as the ball moves away
from the camera. Side view could see the backspin value easier while the target view could see the axis.
Just dreaming on how one could measure these values without spending $20000 or even $8000. I paid $1000 for the EXF1.
But for $20k you can get the spin rate measured + - 15 rpms.
Maybe some day Frans can give users measures spin values from the PL again.
So how accurate do these measurement need to be?
Trackman staff thinks the following. (User conference report). All launch monitor manufactures should spec
even their calculated value accuracy.
Action possible if accuracy of the following is
chs < 2mph
club path < 1 deg
attack < 1 deg
spin < 200rpm
carry < 2meter
Unacceptable error
chs > 5mph
club path > 3 deg
AoA > 3
Spin > 1000 rpm
carry > 6 meters

ClubFiiter73,
I have a Purelaunch that I have not used a a few years (I have a FlightScope).
Was wondering if I could get a copy for your software for the Purelaunch.
Thanks in advance,
John
