Pixie comes as a kit.

 

Board builds for several hours.

In the left jack inserts a telegraph key in the right headphone connector. Connect antenna and power supply of 12 volts and you can operate.

The body is made by analogy with the case for Raspberry PI from  adafruit I just scale it.

 

 

Case in 3D.

 

The original Pixie scheme looks like this

Everything is good but when you press a key there is no tone for no self-control. It looks as follows.

 

So I decided to add the tone generator when you press key you hear a beep sound

The scheme began to look like this

 

On board is a fixed frequency quartz 7.023 MHz to switch to another frequency I added switch and connector for external quartz
