Re: Installing draws image

Douglas KI7LIK
 

First, thanks to everyone for helping.  I may be missing something.  I keep getting the same read only errors whether or not the card is in the locked position.

Sunday night and last night i used diskimager, for some reason it didn't work.  After attempting to boot the pi on sunday and nothing happening, i check the card on the pc, it had nothing on it and said it was empty.  I tried again last night, and still nothing.  The card is a pny 32gb micro sdhc card and looks to be a class 1 card.  I formatted to fat 32 before writing the image to the card.  I used the same computer as when i first wrote the raspbian.

I'm thinking its possibly the card or maybe even the user.

Re: Installing draws image

 

Douglas,

A few points:
  • If you are burning the SDCARD from Windows or MacOS, use Etcher. It works really well on those platforms (As well as some Intel/AMD Linux platforms).
  • You do not need to pre-format the SDCARD, the image overwrites the formatting anyway, just use a raw card or understand that you are overwriting sector by sector new partitions and filesystems.
  • Generally, we recommend a CLASS 10 or better SDCARD.  Lower class ones will usually work, but they are more likely to fail as they are really designed for lower duty cycles (and they are often faster as well).
It does sound like you may have a defective card, it is hard to say.  Many of the image writing programs have the ability to verify the writes.  Also, since the partitions/filesystem (except /boot) are foreign to Windows and MacOS, you probably won't see them from your PC/Mac.

Douglas,

  It sounds like you're trying to write the image from your Pi?

  Can you issue an `lsblk` command and tell us anything useful about the drives it shows that you know? (like which ones you don't want to overwrite for example)

  From there we can help you construct a command that should work to burn the image.

  Failing that, etcher on a "real" computer is your best bet.

Got shipping notice today! Ordered Dec 30th.
Looking forward experimenting with it in the woods.

My DRAWS arrived, video inside

The wiki page is worth 30 words (I counted)... and a picture is worth 1000 words so they say, then this video must be worth at least 1030 words.  So here are my 1030 words on the subject.

I go over receiving the board and burning the image from the command line and also from the GUI using etcher.

Stay Tuned for more!

Anyway y’all can provide a link to Draws?

I’d like to determine if I can use this as a blind person, I’ve been of the air for a bit, but would love to get back on.

Re: [udrc] My DRAWS arrived, video inside

 

Justin,

This is an application specific question.  The DRAWS™ HAT is hardware that can provide access to lots of different applications in a high functionality package.  If the application being used has features for the vision impaired, or if the applications work well with a screen reader, then DRAWS™ can be a part of a solution for a blind amateur radio operator.

RPi / DRAWs Connectivity in the Field and at Home #draws #field #networking #avahi

john.chabalko@...
 

This is probably more of a RaspberryPI question than it is a DRAWs specific question but i think this is likely a pretty common use case amongst DRAWs users.

I use my RPi/DRAWs at home and outside (remote). At home i have it join my home wifi on boot, i have a static IP address assigned to it at startup via DHCP and a DNS name assigned to that static IP. I connect to it via VNC or ssh/terminal. It works great.

What the configuration to do you use when you're out in the field and want a reliable connection to it via VNC/ssh? I'm assuming setting it up as an access point and connecting to that access point with your tablet laptop, and then to the RPi via VNC? Similar to this (either bridged, or just a standalone access point)?

Does anyone have guidance on the "ideal" or most reliable way to do this for radio use?

Re: RPi / DRAWs Connectivity in the Field and at Home #draws #field #networking #avahi

Jim Erickson
 

I do the opposite actually. My raspberry pi’s connect to my home network via Ethernet, which I statically map with dhcp and then I set the WiFi on the pi up to be an access point using dnsmasq and hostapd.  Then when I’m in the field, I connect to my pi’s WiFi and use VNC or ssh or whatever. 

I’m just in the middle of configuring a pi with the new Draws_10 image and I do have some notes I could share if interested.

That would be a use case for a 44 net VPN.

Re: RPi / DRAWs Connectivity in the Field and at Home #draws #field #networking #avahi

john.chabalko@...
 

I also haven't figured out yet (due to lack of time on the clock) what the best state for the RPi to be in with regard to internet connectivity. Much of my operating will be done somewhere there's a cell signal, and i can use my phone/tablet as an access point - which would get connectivity to the Pi.

I haven't yet but was going to look into how to get location data from the phone rather than the GPS.

Or should i scratch all that and treat the Pi as a disconnected device except when i'm at home?

I could run a piece of ethernet to it but i've been trying to decrease the amount of wiring i've got running around my radio. The way you suggest though Jim would work for what i'm trying to do. I think i can also have the Pi connect to my home wifi and offer up a different SID for me to connect to it - like you do. I'll look into that as well.

I'll also check out 44 net VPN - thanks for that suggestion Bill

Re: RPi / DRAWs Connectivity in the Field and at Home #draws #field #networking #avahi

 

Raspbian runs Avahi services, which means the computer can be discovered automatically using the Zeroconf system (Bonjour, Avahi, etc.)

If your raspberry pi is named DRAWS-CALLSIGN, then you should be able to access it from other machines like this

ssh draws-callsign.local
or
http://draws-callsign.local:8080

as long as the computers are on the same LAN.  Bonjour is built into most Apple products, Avahi/Zeroconf in many Linux/Android systems. If your Windows box doesn't have it, install iTunes.

Getting GPS from your phone/tablet will be difficult unless they are running gpsd or similar.  You can USB tether or use your phone as a WiFi Hotspot.  Another option is a 4G LTE USB dongle and SIM card for the field -- or a router like in the video discussing 44-net VPN

Using a PiDrive with Draws Hat #draws #pidrive

okiejim
 

I wanted to use my PiDrive as it is already setup as my access point and dhcp server to my ham shack on wheels. I plugged the hat in and hooked up an external 12 volt source. When I powered it up it gave me a smoke signal. I quickly disconnected power. So I then hooked it up to a pi2 that I have. Using the same 12 volt cable it fired up both the pi and draws hat. But it is not recognizing a sound card. I have ordered a pi3 B+ and will try it on that when it arrives. I hope I did not blow the card. showudrc.sh shows it sees the draws hat.

Re: Using a PiDrive with Draws Hat #draws #pidrive

john.chabalko@...
 

Did you enable audio? Towards the bottom of this page

Also - when you say it gave you a smoke signal... that doesn't sound good. Do you know what burned up, or on which board it came from?

Re: Using a PiDrive with Draws Hat #draws #pidrive

okiejim
 

Thanks for the reply. And yes I did enable by removing the # and re-booting. I believe the prdrive drew to many amps and it may have blown or weaked the 5 volt regulator. But when I power it up from the pi instead of the 12 volt power it seems like its powered since I get a response from the showudrc.sh file. I have contacted NW digital radio and they said its under warranty and to send it in so they can look at it for me. Stellar customer service. I will try on Monday when my new Pi3B+ arrives. If I have the same symptom I will send it in with a copy of showudrc.sh. I just wanted to alert anyone thinking of doing what I did. I wish I would have read more about power on this. I thought it might be too much with the hardrive and usb hub I have hooked up to my existing PI. Powering up from the PI may be the way to go this this type of configuration. I will keep this updated with results.
