I recall building similar but using two transistors, had two LEDs I think?.
got from popular electronics mag or.
were talking mid 80's.
I built one for Christmas exchange gift at work I drew Assistant Superintendents name
put into a small box with cut out bars, caution signs along sides. He had on a shelf in his office for years. Probably still does??
was activated by clapping hands or other noise.
May have to build one for my nephews as well as finish up the mini theremin I started 6 months ago.
