Speaking of Atom, my "case" for the Khadas Tone Board
is a JDS Atom...
Required tools:
* Torx T10 driver
* Drill with 5/32" and 1/2" bits
* Utility knife
* Printed copy of one of the Tone Board templates from
https://www.audiosciencereview.com/...ase-enclosure-for-the-khadas-tone-board.5054/ (make sure it's printed at 100%!(
Instructions:
1. Remove 4 rubber feet and 4 Torx screws from the bottom of the Atom. Remove the top of the case.
2. Pry off the rear right weight in the Atom case. I just stuck it to the front right weight.
3. Tape the template to the side of the Atom. On mine the center of the rear-most RCA jack is about 13/16" from the back and 9/16" from the top, but you should verify it's positioned such that the Tone Board will fit. Make sure the USB port will clear the front weight, and preferably the board should clear the front right screw hole so you don't have to remove that standoff. The board will probably be up against the Atom's RCA jacks.
4. Mark the 3 RCA jack holes and 3 holes for the USB port with the tip of a knife or awl. Remove the template.
5. Carefully drill the USB port holes with a 5/32" bit (or maybe even 1/8", then enlarge until the right size. Be careful not to drill into the Atom board behind it. Clean up the hole with a utility knife.
6. Carefully drill pilot holes for the 3 RCA jacks (I just used the same 5/32" bit) VERY slowly drill the 1/2" holes for the RCA jacks. No matter how careful I was the bit still grabbed and mangled the plastic a bit, but it turned out ok. A drill press or different type of bit may have helped but I didn't have that. Clean up the holes with a utility knife. Don't worry too much about them being perfect since the rings from the Tone Board will cover a bit of the area around the holes.
7. Test the fit, enlarge holes using drill in whatever direction is necessary until it fits.
8. Remove the screw rings from the RCA jacks, put the board in place, and screw the rings back on until they're tight.
10. Cut off the rear right standoff from the top of the case, and trim down (or cut off) the right front standoff until it fits. I was able to use the utility knife to remove the plastic braces then break the rear one off.
11. Reinstall the top case. Done!
