My 8yr old son, Alex, practices his spelling words in Morse code every night. He gets 50 homework points for coding his spelling words in any way he likes so why not learn Morse code at the same time, right?

Until now he has been using my Fluke 87v multi meter with an old J-38 Morse key. When the Fluke is set to continuity it works great as the buzzer. I have many other meters with a continuity setting but only the Fluke 87v has a fast enough continuity tester to match my son’s practice speed.

I really wanted my Fluke back on my tech bench so we found a circuit he could build himself to use as the buzzer in place of my Fluke.

Alex is the host for this video and he seemed to have a lot of fun making the circuit and the video. GOOD JOB Alex!

This is the circuit Alex builds in his video to replace the beeping my meter was doing in his old setup.

He started off with a great introduction on why he was learning Morse code.
