John, Here is a photo of my case:? It is thing: https://www.thingiverse.com/thing:4190589 Not sure if you have tried it, but mine does run on usb power. Have the internal buck set just below 4V. Mine

Jerry, Here is the published thing inspired by your design. Always easier to modify than to create from scratch! Appreciate the head start. https://www.thingiverse.com/thing:4190589 Mark

Hi Mark: When I designed the case originally I thought along the same lines as you. I just did not want to solder The STM32 in permanently. Excellent choice though for making the case easy for travel.

Rats, Wished I had seen this a week ago… I have a similar one that I will publish on thingiverse this weekend. The only real difference is that I made my thinner (27mm) by soldering the stm32 to the

Thank you Nick. I removed them.

Hey Bruce, Just a thought, but probably shouldn't post the GCode, at least not with ample warnings, since GCode is for a specific machine. Bed sizes can be bigger, extrusion rates different, bed

John, N6API, created nice 3D printed cases for the rectangular and square Morse Tutor PCBs. Thanks John! I've posted them on my github account at:

Mark, Thanks. Jerry / K0ES

Jerry, Thanks, I am ok now. It was pretty easy to duplicated it in Fusion 360. So when ahead and did it Just working out the usual nits where things are off 0.5mm. ? Pretty much the same design,

Mark, I did the original on Fusion 360. I'll be glad to send you whatever you need. What format is that? Jerry / K0ES

Jerry, Any chance you can share the original CAD files? I need to make some mods since I am not going to use the double headers on the lcd (soldering the stm32 directly to the board). thanks! Mark

OK this does work! Purchased a 2.5mm to usb 2 adapter from Amazon. ?And it appears to work on both my 2.2 and 3.2 versions using the original boards (where you had all those wires all over the place

(Sorry two queries in one day...) Building the stm32 version with the "long" 2a board for travel. Has anybody tried running a USB to barrel cable and powering it off your laptop? ?Spec says 500ma

Thank you! 73 Mark

I've built 5 of these tutors and the speakers sound fine to me. 73 Ken WB2ART

Hi, Got my boards, and getting ready to assemble it. The new boards have a small speaker that is soldered to the board. Does this speaker sound OK? Hate hearing oscillators that sound like "buzzers

The 2.8 inch displays for a W8BH Morse Tutor (ESP32 Rev 2B) that were shipped on 4 JAN came in today (25 JAN). So that took 21 days to get here. Today is Chinese New Year. So in a couple of weeks, the

Too bad... I have several extra of both versions... :) In case anyone else comes along, I could probably part with one.

Never mind. Just ordered 5 boards.? Looks like I will have some extras in a month or so when they arrive. Mark

Looking for a board to populate. Can order from China if necessary, but just don't want to end up with extra boards to get rid of. :-) Thanks 73 Mark AJ6CU
