You got here because you want to know about the Vibroplex electronic keyer or you're interested in making you own circuit boards?

 

A PICAXE-08M2 VIBROPLEX ADD ON ELECTRONIC KEYER

(with no relay)

This is the MKII project so to speak. It does not have a reed relay output. Just a 2N7000 MOSFET.

 

This page is also a simple Wiki on how to etch out awesome backyard circuit boards!

The BASIC Code

 

Possible issues with this project:

    1] I do not know how long the CR2032 3volt Lithium button battery will last. Hence the reason the links are included to conserve battery voltage if removed.

    3] I used a 10K resistor on both status LEDs. Hence they are very dim to conserve battery. Possibly change them to something around a 4.7K if you

want something brighter.
