Re: Balloon launch this Saturday? Helium?

Curious that the station icon is the same that Bob Bruninga has been using around Logan (WB4APR-7). A search on aprs.fi also shows a GDHILL-8 in Pennsylvania, at Governor Dick Hill, last beaconed on 15 July. The same day that Bob participated in the Appalachian Golden Packet Event from Governor Dick Hill. No identifier there either. Could he be the culprit? ;)

Just an observation...
There looked to be one of the retrival team that was using a TH-D72 with the callsign of GDHILL.
No other identifier...

Fortunately it landed in a cleaner pond. No word yet on payload
damage.

It appears that the balloons I ordered will not arrive by Saturday, so
I'm now looking at a launch early next week or a week from Saturday.

New HAB PCB

Jared Smith
 

I finally finished the design of my new PCB. It houses the GPS, charge
controller, and transmitter. This will function as a shield that will
mount directly to the Arduino Pro Mini via pin headers, thus
eliminating all wires (except to the solar panels) and decreasing the
weight quite a bit - to maybe 12 grams total.

The Arduino and this PCB will sit back to back. The PCB is the same
width as the Mini, but twice as long. The GPS, connectors for the
tether, and antenna counterpoise connector are at the top, and the
transmitter and antenna radiator connector are at the bottom. The
charge controller stuff is in the middle of the PCB.

There are high odds that something won't work. The PCB design's a bit
sloppy. But I'm to the point where I had to order boards to start
testing. They should be here in ~3 weeks.

The schematic and renders of the PCB front and back are attached.
Feedback or comments are very welcome.

I'm planning to launch a balloon with my previous design this Saturday
if the weather is suitable.

Re: New HAB PCB

Jared Smith
 

The new PCBs are here. Photo attached. With the exception of the 2
small solar cells, antenna, and PCB components, this will be
everything for the payload. I've no idea yet if it will work - I have
a lot of find soldering to do before then. But I've already discovered
a minor issue you might be able to help with.

I'm not sure if I sized them wrong or if this drill holes for this fab
house are too small, but the holes for the header pins are too small.
My header pins won't fit through them, so I can't readily mount this
to the Arduino. You can see in the photo that the holes across the top
of my board are smaller than the Arduino ones. They shouldn't be - I
used the official Arduino cad files for the sizing, but something went
awry. Grrr!

Is anyone aware of thinner gauge pin headers that might work? My other
options seem to be grinding down some standard header pins to fit - or
cutting the male ends off of jumper wires and fashioning my own. Any
ideas?

I'll start soldering tomorrow.

Thanks,

Jared

Grinding the pins would frustrate you a bin as they are already small. Since you only have a few Arduino connections the best route would be wire wrap gauge jumpers.

Re: New HAB PCB

Jared Smith
 

Bob -

Yeah, I agree that trying to grind/sand them down will be a major
pain. There are 10 header pins between the Arduino and my PCB shield.
If it's not clear from the photo, they'll mate back-to-back.

I think I'll try cutting the male ends off of jumper wires. They're
just a bit thinner than the header pins, but thin enough to fit though
the holes. I'll put them through the standard plastic header spacers
to provide the stand-off. I think that should work, at least until I
can get another order of PCBs here. I've already fixed this and a few
other minor spacing issues.

Thanks,

Jared

Upcoming balloon launch

Jared Smith
 

Hey all! This list has been pretty dormant of late, but Kevin and I
wanted to let you know of an upcoming balloon activity and launch.
This is primarily for hams and their children who have participated in
previous balloon activities, but we'd love to have feedback, helper,
balloon trackers, etc. participate.

We're planning a few meetings for the kids to prep the payload and
learn some skills over the next several weeks (first meeting next
Thursday), with launch planned for Saturday, June 15.

We're going to be flying our standard APRS and fox beacon
transmitters, with a couple HD cameras, but will also fly a LORA
transmitter sending real-time telemetry on 900mhz. We'll be building
self-enclosed LORA receivers for the kids to track and monitor the
payload during the chase. If you'd like the Arduino-based LORA kit
(which will require some assembly, soldering, etc.), let us know ASAP.
Pricing will be somewhere around $50.

Cheers,

Jared (N7SMI)
