T' followin' circuits are very simple t' make. For t' first circuit, use a small piece o' perfboard t' mount t' components.

T' locator will blink t' LEDs alternately and sound a loud beepin' tone....very effective for locatin' anythin' lost in t' weeds or in t' dark.

T' second locator uses a small piece o' circuit board. Ahoy! Etch a small grove down t' middle on t' foil side o' t' board, drill t' holes and solder t' components where shown.
