Re: SD Reader Difficulty (MorseTutor, ESP32 version)
Vince,
Hate to differ with you, but despite all your suggestions, the solution to the SD card read failure is, as Bruce suggests, a coding issue. Tinkering with the code line values in Bruce¡¯s hack, results in a well-performing Tutor.

Secrets to getting the card to work.
First, review page 9 of the User Guide (Part 10) found here
Then,
1. Ensure you are formatting the card in FAT, not FAT-32, not ex-FAT ... just FAT.
?? (if you see the first letter truncated on the filename, it's a good indication the volume format is incorrect)
2. Ensure your filenames are following the MS-DOS 8.3 filename standard and without spaces in the filename.
3. Ensure your files are plain text files when they are saved.
4. Most importantly, insert the card into reader and then turn on the power to the Tutor. The display does not support hot plugging the memory card.
If you build your card on other operating systems like MACOS, you may see a structure that looks like this where one filename has a leading underscore "_" character:
_TEST.TXT
TEST.TXT
in which case you select the lower of the two files.

Re: Morse Tutor Schematic
I have located a schematic for the ESP32 version. I've attached it in case someone else needs it. (PDF warning)

Re: Morse Tutor Schematic
I've built a couple, I don't remember a schematic, and I didn't find one in my project doc folder. The pcb is well labeled, that's what I used to build. You can take a pinout of the ESP32 module and quickly draw in the connections between the modules. That's what I did when troubleshooting a defective key jack.

Does anyone have a schematic for the ESP32 version of the tutor? I've checked the website and github, perhaps I've overlooked it?

Re: SD Reader Difficulty (MorseTutor, ESP32 version)
Bruce,
Thank you for the tip. ?I believe the change ("hack") had already be performed so I changed it back to a "1". Still no success. ?I returned the value to "0" and saved the sketch, followed by?
recompiling/upload. ?The SD card reader now is performing perfectly. ?By the way, my Arduino IDE prompted me to update my libraries...not sure that played a role but at least I am up-to-date.
Hope this post is useful to the others who have had problems with the SD card reader.
Really love your Morse Tutor...TU TU TU. ?

I tried a little test. I also uploaded a file names reamble.txt On the tutor I selected reample.txt and it is working.

Re: NTP-Server - location of STL case files
Mitch,
I put mine in an aluminum box.? ?I only 3D printed the front and back panels because I didn't want to drill the aluminum (and it looked cool).? ?Perhaps someone else has 3D-printed a full enclosure.

Hello Bill.
You asked what color enclosure I would want for the MCT.? I am not
choosy.? A friend made me an enclosure for one of the mct's but it
does not fit the board it was for.? It was the friends first
attempts to do 3D printing.? I am like you in that I was building
both Bruce's (W8BH) MCT and his pocket MCT.? I prefer the pocket
mct and it is a great option when you have to take it somewhere
(like a club meeting).? I prefer and enclosure though as live
electronics die a violent death on my work bench that I use the
Pile it method on!? I do love to build though and have several
projects on the bench now.? Most are timers (UV timer, or photo
timers) but one is a VK3BHR LCR meter.? I prefer his design since
it measures low capacity and inductance parts where the Chinese
offerings seem to balk at anything below 25pf and 25?h.
I prefer cw.? Right now I am off the air for lack of a decent
antenna that works.? I have a 500ft inverted VEE doublet up but it
does not work.? I think it is because the solid core ladderline
wire has a break in it somewhere. Also it is only up 20ft.?? I
used to be very good at cw but that was back in the 70's so not so
much any more.
I am glad the LA3FY chimed in with the link to his gerbers.? I
thought he had given them to me before but I could not find them
on my hard drive.
I was not familiar with teh KS4NS version.? Where did you find
information on that one?
I have been in a library a couple times here but found their
offerings to be totally useless.? I understand that they can not
keep books on the shelf that are current but books on the Arduino
or even the PIC have been around for several years and are and
were very popular with the maker crowd so I would have expected to
see at least 1 on the shelf.? I had seen a lot of people state
their local libraries offer 3D printing as a service.
You mention working for a university.? I retired from CWU (Central
Washington University) as an IT specialist 8 years ago.? The
university library was not too bad,? at least they had books on
computer related subjects.? Also since I maintained the computers
in the Cad labs I had access to 3D printers.? I never used that
service but I had access to them.? Now I live too far away to even
attempt to use them.
Thank you.

Karl I don't know the formula but when I sent the gerbers it was $33 for 3 boards. I found that very reasonable and I have always been satisfied with the quality of their work. So I ordered them. :-) Worst part now is the wait but that has never been unreasonable either. Thanks again. bill KB3YV

Yes, and I spoke with Jack (I am already in the other group) and he said he never did a PCB for it. Someone had to. The mounts for the board inside that case are smaller than any of the other boards. Thanks for the help. bill KB3YV
