Hamclock RPi project on Joggler? - FIXED

Hi,
New to the forum, but have had a Joggler for a while & have been looking for a use for this solid little gadget.
As a radio amateur, I like the Adafruit Huzzah project 'Ham Clock' over at the Clear Sky Institute:
https://www.clearskyinstitute.com/ham/HamClock/ This takes a bunch of useful amateur radio data (UTC time, local weather, satellite passes, moon phases etc.) and displays it all on a simple display, minimum 800x480, with touchscreen control to change displays, enter data etc (the designer has even written the touch keyboard into the software).
I was going to buy the Huzzah kit, inc. touchscreen to build one, but then thought: if it is a. a small-is app & b. runs on Ubuntu/Linux, *perhaps* it would be perfect to get working on a Joggler?
I can get the Ubuntu/X11 working on my Windows 10 laptop using WSL2 & XLaunch/Xming (see image attached of it above, running on the laptop), so I know it will work on Ubuntu, but my question is that if I load the Bionic Kernel onto my Joggler (via a memory stick), is it possible to get this to run on the Joggler? I believe the display of the Joggler is 800x480, so should it/would it run without major modifications?
Thank you in advance for any help with this - it would be great to have this working on my desk like this & it would probably be of interest to other amateurs here.
Jo.

Just to follow up on my own post, naturally I have tried loading it to see if it worked!
The screen display remains at the standard display (IP address etc.), but opening the diagnostic file in the Ham clock software, I have:
argv[0] = hamclock
HamClock version 2.60
Can not open X Windows display
I assume I am missing a bit of the X Windows setup in order to write the screen display to the Joggler?

@jothebulb great job
as a fellow amateur I'm interested in getting this working and also other ham radio uses for the joggler , I did have it working as both an SDR and picking up airplane beacons but via Android and although it worked it was not well .
Under Linux I'm sure SDR could work .

Liking this, yes, more detail please!
On my list of things to do with a Joggler is to take the data from the FlightAware setup in the loft and display it. In all honesty it should be trivial to achieve given there's a map interface in SkyAware. I recently discovered that Apple's HomeKit supports issuing commands over SSH, so I can also have Joggler displays turning on and off based on room motion.

Hi,
Sorry for the silence, but I have been working away from home recently.
The steps I took to get the Hamclock working are outlined in a Wiki page I wrote for the amateur radio community, OARC, over at:
https://wiki.oarc.uk/hamclock_joggler
As I say, I am no coder, and this is probably a pretty ugly way to get this working, but I have built two versions on different memory sticks now, so the fundamentals must be right somewhere. Please do take a look & suggest improvements.
Jonathan

Thanks Jonathan I'll take a look , I'm doing the Full Licence course on OARC at the minute .

When I click on the link it says page doesn't exist
. Did you remove because you are making alterations to the instructions ?
I'll await your reply before trying .

Hi,
The OARC wiki had a bit of an edit to create pages for members, so the page got moved - I edited my original post to show the new page address, but your reply still shows the old one. Try this address instead:
https://wiki.oarc.uk/hamclock_joggler
Let me know how you get on; as I said, I am not a coder and getting it to work was trial-and error (mostly error). Let me know if you see a more elegant way to achieve this.
Jon.

"No space left on device"
Were you trying to install on the internal memory of the device?

But you managed to get the HamClock running? Any major differences to the way I described the procedure?

Way back around 1965-1966 I was tinkering with amature radio.
Built a radio shack under my parent front porch at the time. Main receiver was a Hammerlund HQ-150 and Hallicrafters radio and used a Knight Kit 50 watt code transmitter. Strung up a dipole antenna from my parents house to a nearby building. I remember getting yelled at a bit for climbing on the roof to attach antennas at the time.
Looking forward to returning to that hobby someday soon.

Great getting that working Pete
.And good luck getting back on the airwaves .
I'm sure there are still lots of potential other uses for Jogglers and radio .
I have used mine for SDR on Android and also to pick up aircraft beacons , again on Android just because it was easy to set up but the results were just ok.
I suspect on Linux both would work a treat .
Also I used as a part of a MMDVM hotspot to view the main log in via Linux , this was using a pi zero .
There's a 32 bit build of a Ham package called Andys Ham that I would be interested to see just what would work .
Here's to plenty more uses in future .
