Cind eram elev in cl. a III-a parintii mei aveau un papagal, Ia care tineam foarte mult.
Printr-o intimplare am ramas fara de el.
Frecventind cercul de radio-telegrafie de la Casa pionierilor Beius, inca din clasa a V-a m-a preocupat ideea realizarii unui papagal electronic.
Abia in acest an dupa experimentarea mai multor procedee, am reusit sa realizez ceea ce doream atit de mult.
Lucrarea functioneaza astfel:
— Comutind intrerupatorul Ix intra in functiune etajul de audio-frecventa, iar comutind intrerupatorul I2 se pune in functiune sistemul mecanic de antrenare a benzii de magnetofon cu circuit inchis, si in felul acesta capul de redare preia semnalul inregistrat in prealabil pe banda. Banda avind un circuit inchis (adica in inel) da posibilitatea repetarii inregistrarii.
Cuvintele ia care ne-am gindit sa le inregistram au fost urarea: “Succes participantilor”.
