Ted, I did a search on QRZ.com and found almost no hams in Nigeria. One of the few that did turn up was Bert/WB6QCS who operates from there as 5N7RSB. I suggest you look him up in the Callbook or QRZ,

Thanks for the advice and referrels. Much appreciated.

Greg, Thanks for the referral. I see they also manufacture 4mil thick polyimide boards. Might be even lighter.... :-)

Would have been interesting to hear the debrief. I wonder if they decided a fixed-fixed wing alternative provided more flexibility in coverage than the "mostly" unguided floating vehicle. https://medi

Question for those of you building ultra-small trackers for pico balloons: What thickness of FR4 boards are you using, and where do you get them manufactured? Many shops will build 0.0625" thick, but

Sorry to hear of their exit, it was interesting to follow their exploits. One of those unfortunate circumstances where you have to spend many millions of dollars just to find out if a cool idea is rea

Will anyone be posting the PowerPoint presentations from the conference? Those of us who could not attend would love to see them. Chuck / KG5CA StratoCasters

Joe, I looked back in my CHDK scripts, and I used the command set_focus 99999 to set the focus at infinity, while the exposure is still on automatic. I am attaching the script file that I use. You can

Joe the Satellite Surfer, I have always been a big fan of Flight Track and use it on my laptop when balloon chasing. I just checked out your new on-line version and you have certainly outdone yourself

Thanks for the interesting comments and ideas. It certainly provides some food for thought fornext year's eclipse. Chuck / KG5CA StratoCasters

It would be nice to have some camera buffs speak up on this topic! I have caught images of the moon on prior balloon flights and it was generally small and somewhat blurry (due to movement). The rotat

I would like to thank all of you who posted and emailed me with your great ideas, suggestions, and comments. My brain is now buzzing with new concepts to try out in the quest for the ultimate-standalo

This weekend while chasing our balloon, I was frustrated by the myriad of wires, cables, chargers, radio, laptop, TNC, etc which trapped me into the passenger seat of our car. Afterwards, I have been

Joe, Flight Track is all I use for balloon tracking and chasing. Thanks for all your effort in keeping it updated and in adding new features. This is an excellent piece of software that freely you sha

A lot of balloon hobbyists use USB-serial adapters based on the FTDI chip. Apparently FTDI has decided to crack down on fake chips, and that crackdown will impact those who have unknowingly bought ada

I think Darryl raises a valid concern about safety with respect to aircraft. Leo's balloon and payload were quite small, so maybe the grape analogy holds (though I still have some reservations about a

I am sure that the Ublox is a fine GPS unit and performsjust as you have explained. Yourenthusiasm for the brand is duly noted. The original post asked about US-sourceable units that couldbe turned of

GlobalTop (and thus the Adafruit GPS module) is pretty clear on their height restrictions (http://www.gtop-tech.com/en/software/Software_Services_13.html). The prior restrictions were set to 60,000 ft

Zack, We use the GlobalTop FGPMMOPA6H which has the high altitude firmware and is compatible with power control at altitude. We use the Argent T3 power control function to turn the GPS off during flig

Like many of you, I am a big fan of the arhab.org website. It provides a great opportunity to announce upcoming launches as well as review past flight activity. I thought it would be quite useful if e
