DRAWS Setup ans Operational Manual? #draws #setup

 

If and when will we see these manuals online?
My DRAWS should arrive next Monday and just wanted to read up.

Hi Brian,

Nice to see you too.

As for the Draws RPi hat, I was actually trying to avoid VNC because you need another computer or your mobile phone to run VNC.
Really I would like to use only one computer when portable (i.e. only the RPi or my mobile phone) not another computer as well in order to control the RPi.
If I have to use a mobile phone or tablet I can use a Wolphilink Interface with my mobile phone or 8 inch Winbook, so the RPi is not needed and I can save a lot of battery power this way!
Battery power is not to be wasted while portable!

At least this is the way I would like it done! Others have their own ideas and are respected!

Thanks for the reply!

Demetre,

It is so very cool to run into you again after 20 years.  Regarding your description below, if you don’t mind I’d like to tell you how I have done this with my HF portable rig.

I never touch my Pi or radio at all while operating digital modes.  Instead I host a WiFi hotspot on the Pi that is always running and hidden away in my rig backpack.   I connect to WiFi with my phone and bring up the interface either with http, ssh or VNC tunnelled over ssh (depending on the app).

For example:  
Pat : http, or ssh
Arim/ardop: ssh (works really well)
Fldigi: VNC or ssh+nc to the telnet port.  I also have a script that starts fldigi in wefax mode and tunes the rig for hands free operation.
Flrig: VNC
Hamlib scripts to automatically configure the rig for each mode: ssh or VNC with .desktop icons
Direwolf: ssh to stop and start
YACC: VNC

A typical operation sequence would be.

1) connect to WiFi
2) connect to Pi using ssh
3) run script radio_on.sh
4) run script direwolf30m.sh
5) disconnect

This could be automated with a webpage, but this works just as well for me, and for most operations it is as easy to use as sending an email with your phone.

Really it would be self contained only if it allowed a 3.5 touch screen to be plugged on top of Draws as a Hat and even better if it came in a dedicated box preferably with a 5 volt battery inside the box.

The way it is now, you need so many cables and this is far from suitable for portable operating!

I hope the makers will think about it in the next version.

They’ll ship by then but you won’t receive them until after the Holiday.

Brian and John,

1. Is the Compass based software footprint such that one of the new RPi 3A+ (512MB) units could handle the apps or combination of apps needed?
Seems like the smaller DRAWS plus RPi 3A+ footprint might be an interesting project to consider for "PnP" users.

Since the RPi 3A+ is unobtainium at this point we have no way to test.  Our product plan does not currently contain any plans for the 3A+, however, it seems to meet the specs for dedicated applications.  If someone wants to develop an open source case for it and provide experiences, we would be glad to share them.  

The DRAWS driver(s) does not add much overhead, so this is more of an application question.  Does the desired application run satisfactorily on a 3+ in 512MB?


2. With your NWD ambe 3000 dongle added, could local RPi audio stream be encoded and transmitted?
For question #2 would be using an "all band" rig with a 9600b port for DV.

Yes, but there is no easy software to do that at this point.  This is not an application that we have in development, but invite open source developers to create such an application.   G4KLX's DummyRepeater is a possible starting point.

 

May be an ignorant Q: It seems like an RPi could use the XC3006 to cross mode through rigs connected to the DRAWS board. Am I off base there? I still have not had any time to peel the XLX onion yet so am only thinking out loud now - don't understand the needed processing power issues etc...

Remembering that the XC3006 was a special run for the XLX folks, it is not available for ordering.  The XLX group does not recommend the Raspberry Pi as a platform for their ambed daemon, though it has run in such a configuration (it is not supported).

 

Thanks for your thoughts.--

Re: Updated DRAWS Brochure Uploaded #draws

 

Here’s the print we’re using for case quotations. The mini DINs are ~13mm Tall and there is 11mm between the PI and the bottom of the 0.062” DRAWS Board.

I have a DXF Cad file as well which I will release to anyone who wants to make a case, provided they open-source the result.

Re: DRAWS Power

 

The onboard regulator is 3A at ~5.1V regulated at the Pi so there is no cable loss. The Pi is sensitive to under voltage.

I recommend using the 12V input.

Yes, it feeds 5VDC to the Pi through the GPIO header.
 

Or

Pi power connection @ 5v with a 2.1amp common Pi wallwart power supply (micro USB connector) will power both the host Pi and the DRAWS board.


 
The current is dependent on the model of Pi,  I typically run 2.5A or better to have some margin.

Re: DRAWS Power

 

DRAWS has an on-board buck regulator to power the Pi from the same 12V source that powers the Radio.
