Re: ESP32 Programming #esp32

#30

I built my first Mega W8BH Morse Tutor with a Mega2560 Pro Mini on a
breadboard. I have also put one together with a Mega2560 R3 full size
board and a breadboard. I have three different types of Mega2560 Pro
Minis. One is a RobotDyn with no USB port (I program it with an
Adapter), One is a RobotDyn (Embed) with a USB port. And the other one
is a Meduino with a USB port. I was building a K3NG Keyer on a K5BCQ
PCB, and I kept buying the wrong board. The RobotDyn (Embed) was the
one that finally worked for that project, and it was the last one I
bought, of course. I am hoping that one day Bruce will make a PCB for
a Mega2560. ;-D

In this version of the PCB, the ESP32 needs to be removed from the PCB for programming. So it is a good idea to solder female headers to the PCB so the MCU can be removed and replaced.

What's the best way to be able to program the ESP32 once on the board? Seems like the port is too close to the knobs, and even if they weren't, does a plug have enough depth clearance?

I've seen his page... looks like the schematics are there, just need to create a gerber file and send it off to pcbway!

Hello Bruce, W8BH,

I was looking for Capactive Touch Paddles the other day and came
across this one by W0UKD:

Unfortunately he doesn't seem to have any PCBs left, but he did offer
a PDF of the board that can be etched at home.

The interesting thing about the circuit is the use of the AT42QT1011
chip which is a One Channel Touch Sensor IC. He also uses an
IRFML8244TRPbF MOSFET, as well as a couple of resistors and
capacitors. He has a nice explanation of battery life for the circuit
(over 3000 hours!) using AAA and AA batteries. It seems very simple.

On 11 November I had a functioning DIY Dual Lever Paddle that I started in September. It is made of brass with a steel base and weights 3 pounds 15.75 ounces. I have it hooked up to my W8BH Morse Tutor.

During the build process, I drew many diagrams and took some snapshots of the work-in-progress paddle. I put these up on Google Drive.

Re: Switching email addresses for groups.io

#17

To change your Group email address...

Using email, I would just subscribe to the Group with the new email
address that you want to use, then unsubscribe the old email address
that you do not want to use.

The Group is setup so that non-members can read Messages at the Group
Web-site. Messages sent to the Group via email will be received by the
whole group. The message I deleted was the public one, since you
listed two email addresses in the message. Those are two less email
addresses for the SpamBots to collect, eh?

Re: Files section #resource

Hello Jim, WA7DUY,

This is a Free Group that has 1GB of storage space. Once that 1GB has been used, I have it setup to delete old message attachments. The Only Constant is Change. Messages are not counted towards storage space.

The following GitHub repositories have files related to the W8BH Morse Tutor (which is currently under active development):

Tutorials, Builder Guide, User Guide

Source code and Gerbers for STM32 and ESP32 versions

Source code for Mega 2560 version:

Source code for Mega 2560 contributed mods (GM4CID, so far):

I think that volatile files that are frequently updated are best kept at GitHub? Do you have a static file that you wish to upload to the Files section of the Group? If you would like to try, please do, and let me know what happens. I have not done anything with the Files section yet, so I do not know how to configure it, yet. ;-D

Mark,? you can just change your subscription email address without joining under another address or quitting the group and then rejoining.? To do that log in to your groups.io account.? Once logged in then go to this group home page /g/w8bhMorseTutor? then click on the drop down arrow to the right of your name in the top bar and select account.? In those settings it lists your email address (and password but not shown).? You can change your email address there.? The one gotcha or be aware is that it changes your email address for all of your groups.io groups that you are a member.? Perhaps you want that, and perhaps you do not but be aware of it.? If you did not want to change it for all of your groups.io groups then you would need to do what you did and create a new groups.io account under your new email address and join the group with it.

I am not sure if that helps or not.

Good luck.

Re: Binary for STM32 Blue Pill #stm32

#13

For some reason (as yet I have not figured out why) the Blue Pill (STM32) sometimes is very obstinate when Downloading the binary from the Arduino IDE. 

I have loaded the ST Micro tools.  I use the ST tool to download the binary that is output by the IDE. 

I never had enough time to troubleshoot the issue.  If you have trouble getting the binary downloaded, let me know and I can post the exact procedures to get the binary downloaded.

You can also use the ST-Link direct from the Arduino IDE, just choose the correct programmer in the Tools menu! :-)

I have used JLCPCB exclusively. ?They are excellent - especially for small quantity test boards. ?Once the test board has passed all of your design based testing, larger quantity production runs can be done through many PCB production houses. ?Several are here in the states.?

I am always amazed how fast I get small quantities from JLCPCB. ?

I also found the St-link to be the simplest way to program the blue pill. Could not get the usb way to work on all blue-pills. And the serial adapter works, ?but the first one was bad (or I blew it up).?
