[Sebastian] is learning Morse code and CW radio, and of course he needed a telegraph key. Instead of using the terribly unergonomic paddle style key, he built a capacitive touch iambic key over the course of a few evenings.
An iambic key usually has two switches. When one switch is closed, it will transmit a ‘dit’. When the other switch … Read the rest
Hackaday has seen dozens of Morse code keyboards over the years, but [Hudson] at NYC Resistor finally managed to give that idea the justice it deserves. He built a USB Morse code keyboard with the same type of telegraph key the pros use.
For his project, [Hudson] got his hands on a wonderful iambic paddle that is usually hooked up … Read the rest
When most people think about a telegraph key, a piece of 1890s tech with a lever that moves up and down comes to mind. These ‘straight keys’ were terrible for telegraphers and led to repetitive stress injuries like carpel tunnel syndrome..Iambic keys came along and move the contacts to a horizontal position. If you ever see a HAM playing with … Read the rest

More specifically, it is that piece that you always see people clicking with their finger when they send a telegraph. We hadn’t seen an iambic or “dual lever” style before, but we … Read the rest
