Re: Raduino / LCD display
I used self stick standoffs from Tayda. No screws to show thru the front panel and it hasn't moved since I put it in. It did require some minor trimming of the base of the standoffs tho.
Sorry, no pics.

Re: Raduino / LCD display
The whole of Electronics is accomplished by 'bodging'! Take a look at (particularly Resistance) tolerances, and resultant voltage and current tolerances. Resistors are marked with a 'tolerance' colour-band. Really early (carbon-rod) resistors had body-end-spot for 1st-2nd-multiplier figures. Tolerance was 20%, and that was close enough / good enough for the valve / 'toob' tech of the day - construction of the devices required no better. Solid-state brought in closer tolerances (though manufacture of the devices still had/has intrinsic variation/s), silver>gold>red>black for 10>5>2>1%, but still close enough is good enough (in 'Kiwi' parlance "she'll be right, mate".

I wrote... It looks like I can just get to the USB connector
on the end of the Arduino. I have a 10-turn tuning
pot on the way. Actually I just checked. Even with the "stock" pot I can't get a straight cable into the Arduino connector. I can get to it if I temporarily remove the pot or take the Arduino/Si5351 off the LCD display. I'm going to order the following cable, but I'm still not entirely sure it will fit. If it doesn't, I'll position things a bit differently on the next BITX40. Again, I'll use a rotary encoder on the next one. It won't take up as much space as the 10 turn pot. -- 73 Keith VE7GDH

Akin to "fudging", just the Brit version. A bit like "Heath Robinson" versus "Rube Goldberg" :) .

Actually, that's a USB mini cable. Arduino Nano on the Raduino uses a USB mini-B cable. I just have to find one that doesn't run out of space on the top of the cabinet (I have more room below the Raduino than above it) and ships to Canada. Possibly on eBay. -- 73 Keith VE7GDH

Re: Raduino / LCD display
bodge: ? "make or repair (something) badly or clumsily"
and ?"Bodging?is a traditional woodturning craft, using green (unseasoned) wood to make chair legs and other cylindrical parts of chairs."
Bodging could well be a useful skill for the radio amateur.
I nailed both senses of the word years ago when I hacked up my Arc5 transitter
to have a pi-network output using a chunk broomstick for a coil form..
A rather cool word, may have to start using it in lieu of "jerry rigged".

A week or two back, there was talk of a USB extension cable to extend the connector to the outside. I ordered one and it should be here soon. Now I know why everyone was ordering a 90 degree connector! I'll have to get one of those. -- 73 Keith VE7GDH

I was thinking the LCD display would just "bolt" to the front of the case, but the projection on the end required me to use stand-offs. The board that the Nano & Si5351 are mounted on just "hangs" on the header coming from the LCD display. Wanting to prevent it from moving around and possibly shorting something out, I put a stand-off between the boards. The mounting holes on the Arduino board don't quite line up, but I managed to use a single stand-off in one corner and it should prevent any movement. Perhaps a future re-design will have the distance between the mounting holes all the same.
I used a cutting disk in a rotary tool to cut the opening for the LCD display in the plastic (PVC) case. I marked the opening on the back and cut "inside the lines" and used a file to get it to the final size. I'm sure the fumes from the PVC was a bit un-healthy while I was cutting, but it did the job.
My question (and no, I didn't try checking with a meter before it was mounted) is do I have to worry about the metalic stand-offs shorting anything between the two boards that shouldn't be connected? I'm assuming this is a non-issue, but thought I would ask before it is powered up, hopefully later today.
A few pics are attached, but not of the Raduino stand-offs. I drilled a few holes for ventilation behind the IRF510 heat sink so it can get a bit of air. Now the wiring starts!

Re: Raduino / LCD display
I used?? ~ 0.175" spacers.? 3D printed Bezel and
flat head screws through the front panel.
You can see the spacers in the pictures.? The
back light on the LCD sticks up, so you need spacer for it to
clear and keep things
parallel.

Thanks for the confirmation! Some years ago, I didn't
think 3D printers would be very useful. Now that I can
see that they can be made for printing cases, bezels
and pencil holders, I'm thinking of getting one. I
think it will be a nice addition for radio, Raspberry
Pi and Arduino projects.
PS - the opening opening I cut for the LCD display
isn't perfect. It looks OK at arms length, especially
if you squint. If you look really close, there are
some imperfections, but I'm happy enough with it.
