Making a Case/Enclosure for the Khadas Tone Board

[infinitesymphony]

Posted by @pos in the tone board thread:

@Audiophonics just released a 15€ aluminium case for the tone board: https://www.audiophonics.fr/en/alum...num-casing-for-khadas-tone-board-p-13626.html

Pretty cool. I'm holding out for a North American distributor due to shipping costs.

Me too. Let me know if you see one.

I'd be interested in one also.

Thanks for the instructions @TimW . I just ordered the case tonight!

@TimW, thanks for the effort and great instructions! Saved me a lot of time.

Waiting somewhat patiently for the tone board to show up... thanks @TimW for the instructions!

Photo is too large to post normally...

Wish I could post mine too!
too large a file...

I used my iPhone XR. Normal photo is too large... not sure what phone you are using...

LG V20.

As mentioned some weeks ago, that I was in the process of fabricating a custom machined case for the KTB.
Well, its done, but the KTB has yet to board the plane leaving China, despite my placing an order 5 weeks ago....

As for costs, well lets just say that its not much cheaper than the KTB itself unless we have like a machine run of 20 pieces at one go.

NOTE: The lighting is for illustration purposes only, should one decide to install an additional LED light to indicate power. It shouldn't be that bright.

^ kudos! Looks great!

I like how you flipped the board so the R/L are in the right locations.

Thanks. Glad you like it. But it was originally intended to be finished in black, but my machine shop somehow got that bit wrong.

I like how you flipped the board so the R/L are in the right locations.

The intent really was to minimise the separate machining needed to mount the board onto the case. On most DACs, the R and L are indeed as the KTB originally laid it. I have since found a way to mount it right way round without adding significant additional cost to the machining work.

But ... I still have to wait for my KTB to show up ....

It looks amazing maxx

Ahh is see what you mean about the R/L orientation.

@TimW did you ever put a hole in the front plate to use the onboard LED? I think I will be doing that... whenever my TB shows up.

I never tried it but I was considering using an LED Light Pipe like this:

Just waiting on the case .. and KTB board .. before the drilling commences. Found the spacers at a large ACE hardware. No go at Lowes or Home Depot.



I must say that @maxxevv's case looks to be the bee's knees.

Well done @maxxevv!
How much extra space do you have for sliding the board in place?

I don't have the files with me but its approximately 15mm for the board, excluding RCA connectors.

Edit: Its closer to 15mm rather than 20mm I originally mentioned.
