Errata ~ Part 4 Simpleceiver

Errata in the Part 4 Discrete Audio Amplifier

One of the blog readers, W4JED contacted me regarding the "reversed  polarity" of the output capacitor on the discrete component audio amplifier that appeared in Part 4. The schematic error would have most like caused a smoking of the capacitor (or a very loud bang followed by the smoking). Thank you for bringing it to my attention. The corrected schematic is shown below,

 Soldering Surface mount can get a bit intense so what is needed is some loud music in the background to sort of calm the environment. For your listening pleasure some "Solderin Music"

  1. Hi Pete,
    I have been working on creating PCBs similar to yours using my homebrew CNC machine.
    I cannot find any software that lets me produce 'etchings' like yours.
    I have put something together using Python to create simple rectangular cells but nothing like what you are doing.
    Can you describe your process? I am sure there are many others similarly interested.
