This "thing" provides a full set of part to enclose, use and display the Morse Code Tutor board designed by Bruce Hall (W8BH) for his Rev 2A board that uses a STM32 processor and a 2.2 lcd. Be aware that there are multiple versions of this board and some use even a different processor.

Credit should also be given to the original creator of this concept, Jack Purdum (W8TEE), that started all the creative juices going.

This is a derivative work of the design that was originally done by Jerry (K0ES) and shared in the w8bhMorseTutor group.io. My design differed from Jerry's in that I soldered the STM32 to the board so that I could make the overall thickness of the case smaller. (see photo)

Also note that I have been successful running this off of USB with a 2.5mm male plug to USB connector with the internal voltage of the buck set at just under 4V.

This also includes remixes of the following other "things"

Knobs: https://www.thingiverse.com/thing:3452325https://www.thingiverse.com/thing:3452325
The main change here was the reduction of the depth of the shaft hole so that when placed on the encoder it would not bottom out and prevent inward press. The "volume" knob is no change from the original. (Suggest print at 103% to fit shafts)

And Stand:

I shortened the uprights of the stand to better fit the box. I also lengthened the carrying arm to better secure the box. I used the uprights labeled "short" but included the "long" ones if that better fits your use.

I printed the knobs at 103% scale so they would fit the encoder and volume shafts used. I also used tree supports on the top of the case so that the various cutouts would not sag. No other supports were used.

I used 5MM nuts with nuts with a nylon insert to lock them in the stand.

The bottom of the case is held in with 3mm screws.
