DIY Straight Key and Dual-Paddle with Iambic Keyer

I have built a Morse code straight key and iambic keyer for Morse code communications.

The straight key was made from brass bars, some bearings, and screw. It was then mounted on the same aluminum plate with my home-brewed electronic keyer with paddles and desk microphone.

The keyer uses an Arduino Uno and a few components such as a potentiometer for adjusting the words per minute (WPM), a small speaker, some resistors, and LED indicators.
