Re: Inexpensive Payload Camera Suggestions - Dash Cam Mode

Zack Clobes W0ZC
 

I've used Aukey cameras before with a USB battery pack. The Aukey does a good job dealing with the harsh lighting conditions that you'll see at altitude.

I tried to buy another one on Amazon the other day and I'm not sure if they're in business anymore. You might be able to find one on eBay though.

What I hope to find is a GoPro knock off with a "dash cam mode."

Ideally, the camera can be configured so that when external power is applied via USB, it starts to record.

Any suggestions?

Re: Balloon cutdown device for sale somewhere?

Martin Rothfield W6MRR
 

I've played with a cut down device but never flown one.  The big issue I see is the cutdown device can fall into the parachute and foul it.  

I go with it on the balloon side and let the balloon serve as the 'chute for the cutdown device.  I have used Adafruit LoRa Feather boards for telemetry - weight < 6 g, no FCC license required.  It's easy to wait for a command from the ground and turn on a FET to burn the nichrome.  Because of the temperature I'd go with these batteries for the nichome.  This shows how ways to switch on the nichrome wire.  With a small battery for the Feather it should be possible to keep the device under  a couple of ounces.  It could be put in some styrofoam to make it even safer.

Sorry, nothing for sale. I don't have time to spin one up but can help online.

Wrap the nichrome wire around the string and it will burn through.

Hi all,

I got an indirect request via Twitter DM to see if someone makes for sale a HAB cutdown device.  The group in question is doing a launch in Florida and one of the requirements is that they have a cutdown.  They previously used a commercially-purchased one but need a new one and that manufacturer no longer makes them.  Other than "cutdown" I don't know the requirements (time, altitude, etc).

Anyone know of a commercial maker of a cutdown?  I did some Google searching and came up empty.  Barring that, a hobbyist-built one might be acceptable, so if you have a working one you'd sell or are willing to built one for sale that might work too.

Let me know if you're interested and I can see about arranging more direct contact.

Re: Part 101

Joe WB9SBD
 

I think I just found it, I knew something wasn't making any sense.

Go to this page

https://www.stratoballooning.org/part-101-rules

Ignore, 1, 2, 3, for now and read #4,

this is all what we are familiar with the 6 pound rule etc. under 6 pounds and 101 really doesn't apply/...

Now go back and read #1
Looks like if the balloon is less than 6 feet in diameter or 115 cuft in volume, this is then just like the under 6 pound rule and 101 does not apply.

am I reading this correctly?

Something to do with the below 500 feet nothing matters or something, because so far the way this is worded it is impossible to do a tethered balloon or a kite.
