Re: [New post] Sample Cases Have Arrived for DRAWS™ Workstation
The case is 2 piece 5052 Aluminum. Given the number of openings required for all of the connectors and the fact that the Pi mounting holes are not grounded, I doubt there is much practical shielding at the higher frequencies.
If you have access to a test facility, please contact me off-group at sales@... and we can discuss further. Bryan K7UDR

Re: newbie question
#draws
The Mirco SD card plugs into the Raspberry Pi. The DRAWs card is a Pi Hat and it plugs onto the GPIO header connector on the Raspberry Pi. You connect 12 volts DC to the Pi Hat which powers the Pi via the GPIO connector.

Re: Installing draws image concerns
Yes. You can use Etcher to burn the Compass image onto your SD Ram card. You don’t even have to unzip the image. Etcher will handle the entire process. It will take ~ 20 minutes so go get a cup of coffe or your favorite beverage. 73 - Mike - KB0FX

Also, sudo "command" runs command as root. If you want to switch to root, use the command su

When using umount, you must unmount a partition, like /dev/sdb1 . You can't mount/unmount a block device, only partitions Steve KC1AWV

I don't personally have a windows or mac machine, but my folks do. I used one of their computers to write the original image to the original card i was using. That computer should still have the program that i used to write the pi os image. I was thinking of that before i received the email.
Thank you.

Re: Installing draws image concerns
Hello Douglas & all, I may have missed parts of this discussion which will make what I suggest below seem really stupid…. See BalenaEtcher It is still an Open Source package. Before being acquired by Balena and moving into the big time IoT, ‘Etcher' worked extremely well under both OSs formatting your SDMicro for RPi use and burning whatever OS and App image you want onto it. BalenaEtcher.app, v 1.5.5 installs and acts exactly like 'Etcher’ did with the exception that during it’s install it wants to access more (most only slightly related) web sites. Before I use it I’ll go back and eliminate all of those cookies and associated Little Snitch permission settings to see if it still works the same. You might want to simply not agree to all of the cookies it wants in order to see which, if any, it absolutely needs to load and ask you which device you want to format & burn an image on. Once Etcher finishes the format, burn and verification of the DRAWS Image (& Compass linux), you remove the SD from your attached SD reader/writer and put it in the RPi., reboot the Pi and follow whatever the latest DRAWS instructions are. Cheers, ...dan wl7coo

Re: Installing draws image
Are you saying it's working, or not working? One more thing... If you're still getting the read-only file system error, then check to see if the physical switch on the side of the SD card is in the write position. If not, then there's your problem.

Re: Installing draws image
Make sure the volume on the card is unmounted first.

Re: Installing draws image

I changed to the /dev/sdb, when i do a look up for devices, it shows sdb as the the 32 gb device, which what the card is im writing to. The card in the pi is sixteen gb. It gives me access denied when i do sdb. Granada Estates Neighborhood Watch

Re: Installing draws image
That error message dd is giving you is correct. You can't write an image file to a directory. You need to write an image file to the device representing the flash card. You want of=/dev/X where "X" is the name of the device. It could be sdd or mmcblk0. You'll have to ls your /dev directory to know for sure. Hope this helps. 73, -Dave W3DJS
