I built my Morserino yesterday.  Thank you Willi! I'm hooked and tried several of the modes. So much fun. I'm going to show off the unit at the next San Diego DX Club meeting. It was worth waiting for my Morserino since meeting Willi at Friedrichshafen.

Construction was enjoyable and the instructions are great. I have one suggestion and one question. 

I stupidly put some pressure on the top acrylic when tightening the hex screws. My thumb covered the thin acrylic section between the USB plug and the copper colored curly coil (? Wifi antenna) and I cracked the acrylic between the two. No big deal as I repaired i and it is unnoticeable. But it is one thing to be careful of.

There is orange tape over the two paddle connectors. Is this to be removed and tossed or used in some way? I notice that the paddles can get out of horizontal alignment so maybe taping the side is an option if the paddles are never to be removed?

73,

Re: Morserino Wakes up

Hi all,

I load my morserino via an external charger (900mA loading current) and tried also the USB choice (120 mA). When waking up the morserino (red button), I never got a battery status better than close to empty.

Howard,

Thanks for your comments.

The tape on the paddle connectors has to be removed - its purpose is to serve as a holding point for automatic placement on the PCB by the pick & place robot. Taping the paddles to the connector is certainly an option in case you are not planning to remove them for transport!

Problem: Keyer seems to use a "dit"-memory

torsten@...
 

Hi,
I have the problem, that m32 seems to have an internal dit-memory. So if I release the paddle, the keyer produces just another dit. This issue exists both in Curtis A and B mode. At speeds around 30+ wpm it is just impossible for me to give an "e" properly - m32 will make an "i". I already wrote to Willi, but I did not mention any other user in this forum who cares about that.
Did you mentioned that issue, too??

got the same problem; also by using an external paddle. As a beginner it makes me little crazy... ;-)

Re: Problem: Keyer seems to use a "dit"-memory

Willi, OE1WKL
 

Hi all,

The is no „memory“, but the paddle press is checked as soon as the „dit“ (or „dah“ for that matter) is over. This means, you have to release the paddle completely while the dit is still going on (with the dah this is less of a problem as it is longer).
Especially with a capacitive paddle this is a bit tricky, as you have to not just release the pressure in time, but the finger has to be moved away from the paddle while the dit is still going on.

I intend to introduce another parameter (not sure about its name yet, maybe „latency“, with values in % (0, 20, 40, 60, 80) of the length of a dit. After a dit (or dah) has been sent, the Morserino will not check the paddle until the time defined by this value has passed. I hope that this will mitigate the problems you are describing.

Let me know if you think this is the right approach (you may also suggest a better name for the parameter…).

Paddle gehen nicht - orange Klebestreifen entfernen!

DG6MCX
 

ich wollte mich erst einmal für diesen tollen Bausatz bedanken. Idee und Umsetzung -> genial.
Meine 12 jährige Tochter hat ihn soben mit mir zusammengebaut. Sie hat gelötet (nicht zum ersten Mal...).

Alles ging - nur die Paddle nicht!
Die Lösung habe ich hier im forum gefunden: Man muss in jeder weissen Steckerleiste die orangen Klebestreifen entfernen.
Warum die da drinnen sind weiss ich nicht, Tatsache ist - jetzt geht alles einwandfrei!

Re: Problem: Keyer seems to use a "dit"-memory

Hello Willi,

I like you approach of "not checking" the paddle for a certain time after the dit. For my understanding, the pause after the dit IS PART OF THE DIT and therefore one could really decide to not check anything during that time. Maybe check at 80% of the pause to not miss a new command?
Just my two cents,,

Hello Willi

Thank you so much for this kit. I love it.
The board is beautifully designed and the finished product is easy to use.
The Detailed Assembly Instructions are excellent and I put it together in a short time.

Some minor things I would change with the board design.
  1. The solder mask colour. I would prefer any colour other than black. Dave has something to say about this on eevblog
  2. The holes for the speaker clips seem a little off. The speaker was loose before soldering.
  3. The solder pads for the black wires ESP32- and LIPO- are not spaced far enough away from the flood filled ground plane. My Weller soldering iron is unable to heat the pads sufficiently to solder the wires. 
I have already started practicing with my straight key using the CW Decoder function even though I have no battery or enclosure.

Battery charging

Timothy Jewell
 

Willi
Great job with the kit, it was easy to put together and worked immediately.

However I am having a problem with the battery charging. I am using a 1000mAh 3.7V battery which appears to register as empty when it gets to approximately 3.55V . When running it shows 70 to 80 mA discharge and when asleep about 15mA. Plugging is a 5V 2.1A adapter when in the off position will light the orange light. Switching over to the on position the light goes out and there is no discharge from the battery. When it goes to sleep there is no current to or from the battery. If I plug the adapter in when asleep the 15mA drops to zero. It does same on the two identical batteries that I have. They both charge normally using an external charger. What is really confusing is that the voltage at the battery goes from 3.5v or so to 4V but there is no current to the battery and the light is not on.

Bit of a pain but just a minor inconvenience as I can charge externally and I do have two batteries.

Thanks, Jamie, for the suggestions.

I couldn’t find the remark about black solder mask on the eevblog - what is wrong with it?

Sorry for the other inconveniences with the PCB - this was pretty much my first PCB design (the first real one, produced in more than 5 samples) , and I certainly can still learn a lot in this area!

Update: I left the unit on to discharge the battery and at about 3.1V the microprocessor gives up. . I plugged in the adapter and it started charging (orange light was on). Charging current was about 70mA. After an hour the voltage had climbed to 3.44V but the charging current had decreased to a few milliamps. At 3.54V charging current was a fraction of a milliamp although I don't think my ammeter is all that accurate. Over the next few 4 hours it climbed to 3.67V. On waking the unit the battery symbol was all but empty. So basically it will only start charging if the battery is very low and stops charging at just over 3.5V. No load charging voltage is 3.74V (battery disconnected). So charging does work but is all but unusable.

Best regards
Tim

Re: Battery charging

Try to keep it connected to USB for at least 10 hours…. This would be the first time that it cannot charge a battery as far as my experience goes. What kind of LiPo battery are you using? Are you sure your battery is just a single LiPo cell without any electronics like charging regulator in it? A battery with built-in charging electronics probably cannot be charged through the Heltec module, as it requires much higher voltage levels than the Heltec module would provide.

I have had to charge externally for best results. Wake up screen will then show 50% battery and I get a lot of operating time. Perhaps this is due to the charging protection in the battery? 

I'm glad I listened to Gary W4EEI and purchased these batteries

They come with a nice USB charger with accurate charging light. Plus, I have a spare battery for the future.

Bug: Tone Shift in Echo Mode does not work

Willi, OE1WKL
 

AS DK4RW rightly pointed out to me, there is currently a bug in Version 1.0: no matter how you set the parameter for Echo Tone Shift, the resulting tone is not changed. I have identified the issue and it will be resolved in the next firmware release!

I am not sure at all if these batteries have an internal charger or not. I will try and get hold of the exact model you have recommended. I can not find it in Ireland unless I buy 6 at the same time for about the price of the morserino. It may take me a while to get one but I will report back when I do. Thanks for the advice.

Dear Willi,

I charged my Morserino via USB over night, in the morning it were 4,09V at 0,01mA loading current. Nevertheless battery is shown as nearly empty :-O

Re: Battery charging

Very strange behavior. I am not sure what’s going in there, and how (or if) I can do anything via Software to improve the situation. Charging itself cannot be influenced by software, but measuring the voltage is a software feature, but apparently a very unreliable one. I will do further experiments (documentation is hardly available), and if I find something useful, will incorporate it into the next firmware release…

v5.2 Tester?

Stefan Großhauser
 

Servus,

hier SRG, mittlerweile DM4SG.

ich hab in letzter Zeit immer wieder an der firmware vom alten
Modell mit Arduino weitergeschrieben. Es ist noch nicht so reif, dass
man es in die dropbox legen könnte, aber vielleicht mag der ein oder
andere dem mal einen Test geben? (siehe zip Anhang)

-> neuer Generator EIGENE, der einen zuerst nach den Zeichen fragt,
die man in 5ergruppen üben möchte.
-> neuer Generator QSO, der aus der Liste der abbrevs und den weitern
generatoren versucht, halbwegs sinnvolle und halbwegs vorbildlichen
QSO text zu generieren. (weil ich persönlich qsotext irgendwie immer am
schwierigsten finde, wenn wir hier im OV üben).
Die Datenstruktur qsotree dafür wird von einem pythonskript
generate_qsotree.py erzeugt. Hoffe, das ist verständlich.

Damit die zwei möglich sind musste der ganze Generatormechanismus auf
Wort-für-Wort statt Zeichen-für-Zeichen umgeschrieben werden, das macht
die Statemachine jetzt viel einfacher, finde ich.

außerdem:
-> verbessertes Copy Game, das jetzt Leerzeichen komplett ignoriert
und dafür im Sinne des qrq automatisch an der Geschwindigkeit dreht.
-> massiv mehr benutzung von CPP macros, damit man die hartkodierten
Zahlen möglichst nur einmal irgendwo hat.

fehlt noch: Semikolon und Ausrufezeichen ordentlich behandeln. Handbuch
update. Brandneue bugs fixen...(z.B. wird die Zeile "(qru wid <ka>)"
nicht immer gezeigt...)


Ich werd das Ding in der Form jetzt mal einige Wochen liegen
lassen und erst frühestens im März wieder was dran machen.

Es wäre toll, wenn der/die ein oder andere YL/OM Lust
hätte mal ein paar mal den qsotext generator laufen zu lassen und
drüberzuschaun. Mir fehlt da z.B. doch die Sicherheit, wo die
ganzen Opcodes wirklich angebracht sind etc. . Deutsch/Englisch bzw.
OM/YL ist der Einfachheit halber nicht konsistent bisher, ich weiß
nicht, ob sich der Aufwand dafür lohnen würde.
Und immer gern her mit Ideen, was der qsotext Generator sagen könnte, es
sind noch ein paar bytes frei im ROM :) und viele abbrevs
unbenutzt oder frei, bzw es gibt noch ein paar, die man ohne großen
Verlust austauschen könnte. Wenn zum Beispiel jemand Lust hätte, einen
Baum für ein contest qso zu machen, pse k.


mni tnx es 73 de dm4sg, Stefan


PS: hat es sonst noch bei irgendwem PIN9 zerstört mit der Zeit (->
Sound spratzelt)?

Battery

What battery is everyone using?  I'm looking at the Tattu battery posted on the Morserino page and the size of the battery listed is bigger than the max dimensions.

Thanks
