New Case for RPi, DRAWS and 7 inch LCD - Looking for testers
|
John Cahill <johnwcahill@...>
Do you plan on sharing the cad files themselves so that testers can add improvements more easily and share?
Looking to get into the next DRAWS cycle in April myself, my intention is to use portable and mobile and this case option would be 'the bees knees" John, N2JWC

Steve and Kevin, I have downloaded your files and will print this weekend. I do not have my DRAWS board yet, but it should arriving soon. I THINK I have the correct display, so I should be able to test the fit of the Pi and the display.

With what tool was the design built? SolidWorks? Would you be willing to share the source files? I'd like to be able to adapt to different displays, mounting configurations and am Interested in building a lipo battery and charger board. 73 - NØNKI - Eric

That's a nice display. It would be nice if the touchscreen model would be setup the same way.

The display is a 12V display. It also has a speaker so you can use Xastir audio alerts without having an external speaker.

That's probably going to be the next major purchase for the fabrication section of my workbench, a good 3d printer. I'm tired of not being able to do things because I don't have a part, especially enclosures.

Hi Basil and Dave,

@Dave, your comments on the RPi screen are pretty much spot on. I had a spare one in a "SmartiPi" case I have been using to test an early adopter DRAWS board during the betas. I posted my kitbash setup about a month ago or so. It serves as my backup and porta-mobile digi right now and will work adequately in the field with FLDigi. I use my workstation and laptop for Winlink - so have not tried to set up those apps and cannot comment beyond the notes below. @Basil - re the 7" 800x480 RPi display - you want to have a (wireless) keyboard with a mouse/pad! 1. Needs to be used in the shade. 2. Once RPi Stretch+Compass is set for "small screen" most stock RPi/Stretch apps work adequately - IF you do not have vision issues. 3. Xastir is usable on the RPi screen once in fullscreen mode. Aspect ratio makes for a weird map field (too short in some magnifications). 4. FLDigi/FLRig needed to be resized a little, but also will work in a trouble-free manner once set up. OTOH wsjt-x has configuration menus where critical that are inaccessible. You can set them up if you know the default states and you know the order that "Tab-bing" through setup selections proceeds, but it is a PITA. Sunfounder 10"/Pi combo Questions: Does the screen run off the buck regulator in the DRAWS card? I originally passed on it because the display unit appeared to require its own PS unit - the display kit with the acrylic stand and integral mounting stuff seems to have solved that issue. I need to eliminate the need for all but one PS (or Bioenno battery) as I did with the early adopter kit. Thanks for your comments- KD4IZ Jack Spitznagel FM19oo

The 7" Raspberry Pi 800 x 480 resolution touchscreen screens are much too small for most (any) apps to work without a great deal of frustration. The 7" Sunfounder 1024 x 600 resolution displays are marginally better but still are not that great a user experience. I find the 10" Sunfounder 1280 x 800 displays work pretty well. Just my opinion of course. I would be interested to find out what application people are using that they find the RPi 7" 800 x 480 touchscreen works well. I do not use any of my 7" displays any more. You can find the Sunfounder displays on Amazon with or without touchscreen. /Basil n7nix Dave Phelps <dave.phelps@gmail.com> writes: Can't say anything about the case as I haven't even received a board

Can't say anything about the case as I haven't even received a board yet, but I can chime in on he 7" raspi screen.
It's not big enough to do any serious work on. A lot of programs with GUIs can't resize that small, and even if you were running it mostly headless and coming in off a vnc with a full size screen, that 7" screen won't allow you to resize your window to a better resolution. I ended up discarding it. That was my experience anyway. Command line users, of course, won't notice a thing.

Looks great, now i'm thinking of how to add a battery to it.

Hi Alexander,
Although we hadn't thought of doing them for purchase we can certainly do a few as needed. Ultimately though you might be able to find somebody locally to print one up for you from the files on Thingiverse. There are several companies that will do the print and send it to you as well. For example : https://www.3dhubs.com/3d-printing/

Hi Jack,
Great comments! The design does grant access to the HDMI, speaker and power jacks on the side but currently doesn't allow easy access to the SD card slot. Working on a modification to allow that now. Yes we had planned on using a header cable and do for the TNCs. We've found (so far) that the Pi's LCD cable is more susceptible to RFi than the GPIO cable but that is from experience with TNC hats and not the DRAWS. We've been able to get past the RFi on the LCD cable by putting a small ferrite core on it. Our intent is to use the regulator on the DRAWS board rather than the buck regulator separately but as we've got no DRAWS board and we wanted to make the design somewhat independent of the HAT you choose we've designed in the ability for either approach. The 7 inch LCD is indeed small for a lot of different use cases. In fact I had intended to use it at WFD but found it too much of a strain on my eyes. Something that we will have to think about going forward. Steve

Hi Ed,
No....but I don't see why it couldn't be done. Let me do some research. Steve

Hi Fred,
That would be fantastic!!! We're on the list for the next shipment but that looks like it got delayed. Do you want to email me privately to arrange something? Steve

Steve and Kevin Do you want to try it with my DRAWS? I am an early supporter in that I invest money, but I have not had time to even open the package. We can trade back once yours arrive? Fred VE7FMN

Nice looking case.
Do you have any experience adding acrylic rods so the TX LEDs can be see better with the case on?

VE7KGV and I designed a case to allow use of the DRAWS Hat with a Raspberry Pi and 7 inch LCD but have no way to test it because we haven't gotten a DRAWS board to play with (Hopefully in the next couple of weeks). As a result we've only been able to design this from the spec sheet. The full design is on Thingiverse here https://www.thingiverse.com/thing:3387482 There are pictures there as well. Would love any input you have on how to improve this design. Thanks, Steve and Kevin VE7GOY/VE7KGV

I really like your concept here. It would answer some of the issues that came up for me while using the SmartiPi Touch Case as far as access to microSD card and perhaps the HDMI port… I could not tell if you had left access there.
Are you are planning on using a header cable for the GPIO? Could that leave the bus more open to RFI in field use.
Folks playing with DRAWS seem to have have found it better to use the buck regulator on the DRAWS board to power the RPi . All you need is a male to male micro USB power jumper like you can get from Drone vendors to route from DRAWS to the RPi. This would eliminate the need for a separate 5V supply. I supply my rig and the DRAWS from the same power source.
The RPi touch screen is nice but issues that came up for many who tried it:
BTW – all the DRAWS discussions are in the UDRC subgroup – Lots of great info there. Jack – KD4IZ
