Re: battery operation #build #tutorial

 
Edited

I use a Belkin Power Pack using the USB outlet at 5V. I never adjusted the potentiometer, so 5 volts is getting through with a small voltage drop I presume. Since an alternate power supply can be 3.7 volts, then this should work.

What I power up there is a blank screen, I then power off then power on (do not know why). The Tutor works properly after that.

And, obviously, any 5V USB source will work, provided it can deliver the current needed by the device.
Re: Inaccurate keying #keys #esp32

 

I had the same issue. How are you powering the device?

you might be a victim of bouncing. Check the interweb.?


First, I used a dollar bill (Texas cotton, pinched it between the contacts and pulled gently to clean then. In my case, no change.?

I am powering the Tutor with a Belkin power pack through the buck converter unadjusted, so a straight 5V via a made up, partially shielded USB cable/barrel jack. I used an unshielded extension. I think the coiled extension acted, well, like a coil ?and periodically caused the keyer to activate.

Odd Behaviour?

Two nights ago, I had my Tutor on while I pushed the PTT on my HT Yaesu FT1XD.

To my surprise, the keyer started making morse, mostly dahs, during the entire time the PTT was active.

I did this with both a repeater setup and simplex.

It must be picking up the RF transmission somehow. I tried a PicoKeyer, and the same did NOT occur.

I am powering the Tutor with a Belkin power pack through the buck converter unadjusted, so a straight 5V via a made up, partially sealed USB cable/barrel jack. Would the cable from the Belkin be acting as an antenna??

I know that the keyer acted weird (a very technical term) that resembles bouncing when I had an extension from the Belkin and I think the coiled extension acted, well, like a coil ?and periodically caused the keyer to activate.

Any thoughts?

PS: This was done as an experiment to send ¡°CW¡± sounds on 2 metres. And, it worked as expected but not controllable.

Ralph (and Kent),

Thank you for pointing out the error on Koch Lession?#19!
I just updated the code on Github.

I was in need for a case for the ESP-32 version for an exhibit at a local Maker Faire. I wasn't able to find one online, so after a lot of trial and error, where I learned a bunch about modeling, I managed to put together a passable case for the project. I'm going to print out one of your cases as mine needs some adjustments to better cover the part of the display that isn't part of the screen and I'd like to see how yours fits.

The Morse Tutor was a hit for the Faire goers, by the way.? Kudos to you and Jack for coming up with such a useful teaching tool.. It was wonderful seeing people from five-years old and up spending time at the booth to practice Morse and sending messages to others at the table. We had two units, one with a straight key and the other with a paddle. Great project!

Oh, forgot to mention that Kent, KC9LIF, pointed out to me that there was a problem with the Koch table. There are two entries for "L" and none for "1".? I made the following change locally, which I believe is correct.

char koch[]? ? ? ?= "KMRSUAPTLOWI.NJEF0Y,VG5/Q9ZH38B?427C1D6X";

That's great news, Dave.
Thanks for the update.

Hi Bruce,
It was the User_setup.h that I had forgotten to check. It had changed.
All 3 stm32F103's work and no problems. Thought I had a forth one but that turned out to be a stm32F104 Blackpill

Have some more stm32F103's coming from China
Have found a small problem with some of the NEO-M8N GPS units, they are marked as M8N but when checked with ublox u-center they are M8L's
To start with they wouldn't work in the clock but found that if you do a revert config and then transfer them to the clock they work ok.

Re: GPS Clock triple Help

 

Yes, if the old and new STM32's were programmed differently, that could make a difference!
Unfortunately user_setup.h gets rewritten, without your?consent, every time you update the libraries.?

Re: GPS Clock triple Help

 

Hello Dave,

Do I have this right?
Old STM32 chip?+ old board = OK
Old STM32 chip?+ new board = OK
New STM32 chip(s) + new board = FAIL

If I have that right, it sounds like the newer STM32s are bad.

A big problem with the Blue Pill modules is that they all use clone?MCUs; none of them use a real STmicroelectronics?STM32F103 chip.? Many were sold that do not have enough memory on board, despite what the Arduino IDE compiler says.? ?Some have only 64K or even 32K of flash.? Some have no virtual EEPROM support, etc.? ?

I wonder if anyone else has had a similar experience?

Buying microcontrollers these days is very difficult.? ?Even the ATmega328 (Arduino UNO) chip is out of stock.

Bruce.

Have been using the GPS Triple clock since Bruce published it and it works great.

Using the same PCB as the running one but all I get is a white screen. Tried the original stm32 on the newly built board and runs fine.
The upload to the stm32 looks good, do seem to remember the timezone error and not a problem.

This is the complile time message.
WARNING: library Timezone claims to run on avr architecture(s) and may be incompatible with your current board which runs on stm32 architecture(s).
Sketch uses 54424 bytes (41%) of program storage space. Maximum is 131072 bytes.

Have tried on 3 stm32's, maybe 3 duff one's

Any help would be appreciated.
Thanks??

I added an enclosure for the Morse Tutor project (ESP32 version with 3.2" display).
See??

Re: LC meter project PCBs

 

Hello Kevin K3TL,

I have received your PayPal payment for the W8BH LC Meter (JLCPCB) PCB.
Thank you. I notified the other fellow that the last board has been spoken for.
I will try to get the PCB posted as soon as possible. Hopefully, tomorrow.

Regards,

Re: LC meter project PCBs

 

Greetings,

I currently have TWO people who have expressed an interest in the LAST W8BH LC Meter PCB from JLCPCB.

So if I don't hear from the first person on the queue by tomorrow, it will go to the second person.

Therefore, this offer is hereby CLOSED.
There are NO MORE W8BH LC Meter PCBs available (from me).

Thanks to all those who responded to my offer.
I mailed four of the five PCBs today.

Ken, KM4NFQ "Not Fully Qualified"
