The blue tack is holding the light pipe in place on the front. Is should probably send pic of my enclosed keyer If you are using agle Cad and would like to share the file for the version that is on this page I would be interested in laying out a PCB for it. I’ve been enjoying playing with this thing and it is consuming much of my time. It is still good you are thinking of it so for others who want 20 buttons on a case they can have those. The AA0ZZ has 3 memories and I’ve never ran into an issue where that had not been enough.
I thought about changing the code to get more memories by adding buttons but the reality is that my case is going to be packed if I any more! At home I use a serial interface I built and CWType. On the muxing you could use one analog port and then use resistors. I guess the non-lazy person could just unplug the tx cable from their radio instead :).
This will allow folks to use the keyer as a practice oscillator. In lieu of the practice feature you may want to add a command that will set key_tx = 0. I’ll have to merge your updates with some of my minor changes. Probably just an issue on my Ubuntu machine. After sending some of the stuff it complained that the UNO had stopped responding. Okay, is there enough room for all those enhancements :) I enabled the the practice feature last night and the IDE had an issue uploading.

Jeff, AC0C, wrote of his efforts to find a CW keyer with an “Old School Feel”.īarry, ZS2EZ, published a web page on his K3NG CW Keyer build, including a schematic and PC board artwork.
KF4BZT Article – Good information for new builders!ĭL1SMF Keyer Project ( English Deutsch)- Stefan has details on his hardware which is pin compatible with this software and his own software. Use 1k resistors I am in the process of updating the schematic. 1K ohm resistors are better suited than the 100 ohm transistor base resistors shown in the schematic. No values are super critical and typical tolerance components may be used. D2, D3, A0, etc.) All capacitor values are in microfarads (uF), unless otherwise stated.
Note: Ignore the numbers on the outside of the Arduino symbol and refer to the numbers within the box for pin connections (i.e.
The code can be used with a full blown Arduino board or an AVR microcontroller chip can be programmed and used directly in a circuit. This is an open source Arduino based CW (Morse Code) keyer with a lot of features and flexibility, rivaling commercial keyers which often cost significantly more.
