Science Fair P-Box Electronic Project Kit: "Metronome"
Radio Shack Cat. No. 28-118
Variations of this basic Oscillator circuit were used by Radio Shack in many of the Science Fair Electronic Project Kits.
This Listing is for the Red P-Box with the assembled circuit as Pictured.
Note: The Original instructions are missing, but I will include a copy of the 6 pages.
Tested: Works!
I have other P-Box Kits Listed with a few more to list soon.
