Kickstarter campaign will go online soon!

Just a few days…. and you should be quick - it only runs for 20 days, and the number of Early Birds is limited! Watch this space, and/or subscribe to teh mailing list!


Morserino-32 will be an exhibit at the TEDx event in Vienna on Saturday, October 20!


Hardware Design Should be Close to Final

Version 2 of the board is now ready for production, and has been sent to the PCB factory. Unless serious issues are discovered, this will be the version that will be shipped with the kit.

Changes / Improvements: 

The output for keying a transmitter is now through a 2-way 3.5mm  phone jack. Keying is done not through a transistor, but through a Mosfet optocoupler. Voltages up to 60V and of any polarity can be keyed now, and in addition provides complete isolation of the Morserino from the transmitter.

A 4-way 3.5mm phone jack will provide audio input (for the CW decoder) and audio line-out. The latter is independent from the volume control and delivers roughly 100 mV eff. audio, which comes pretty close to a sine wave after having passed  a RC lowpass filter of the 3rd degree. This can be used fo applications like iCW (Internet CW - see https://sites.google.com/site/icwoip/), a nice way to practice Morse code with a buddy over the Internet. A standard 4-way 3.5mm audio cable will be needed to connect Morserino-32 instead of a headset to your computer.

The audio input will be amplified by a rail-to-rail OpAmp, before it is fed into the ESP32 processor for audio filtering and decoding.

From a software point of view, the biggest changes I am working on right now are:

  • Support for an iCW transceiver modus.
  • Improvements to the Koch method, making Morserino-32 an ideal device for absolute beginners.

Ordering a Morserino-32

Towards the end of September you can expect to be able to order a Morserino-32 kit. In all likelihood this will be done initially through a Kickstarter campaign - this reduces the risks for both you and me. When the campaign starts, you will see updated photos and videos that give you a good impression about the capabilities of the device. Of course I will announce the start of the campaign through this mailing list!

HAM RADIO Friedrichshafen: Morserino-32 was greeted with a lot of interest!AND:Frequently Asked Questions

Morserino-32 was demonstrated at the Ham Radio 2018, and I think that most people who saw it were quite enthusiastic about it.

There is a short report about it at the blog hamspirit.de (it is in German, but Google Translate will be your friend).

The (bi-lingual) slides of OE6RDD's presentation that featured the Morserino-32 can be found at the site of CW Schule Graz.

There are videos demonstrating some of Morserino-32's features (they were part of the presentation), and you can find the link on this website.

Spread the Word!

If you think that Morserino is an interesting project, please spread the word amongst your fellow hams, your local clubs or your rag-chew partners;  point them to morserino.info and the  mailing list that can be subscribed  here. A higher production volume will bring the price down and hence benefit all of you!

FAQ

There is now also a section on this website, where I collect Frequently Asked Questions (and answers, of course!). Obviously, at this early stage of the project, some of the answers will be a bit tentative - but they will get updates as we march along!
