اچو ته اليڪٽرانڪس پُرزن جو استعمال ڪري هڪ ميوزڪ گيجٽ ٺاهيون. Power supply (either a 9 volt battery connector and battery or a DC 9 volt power supply and jack with lead wires) Wires (an assortment of sizes with the ends trimmed bare and tinned would help) Small Switch (on-off or on-on will work fine) Speaker 16 Ohm 25 W (Actually just about any little old speaker will work) Audio Transformer (you can pick one up at Radio Shack for about $3) Transistor 2N3904 Capacitor Ceramic 0.047uF Resistor 10K Resistor 3.3K Paper (a nice piece of card stock would be nice) No 2 Pencil مٿيونن گهربل شيون هٿ ڪريو ۽ جوڙڻ جي ايڪسرسائيز ڪريو۔
بهتر ٿيندو ته سامان کي ڪجهه مختصر انداز ۾ لکڻ گهرجي ته جيئن سمجهڻ ۾ آساني ٿئي يا تفصيل کان پوء هيٺان اختصار ۾ سمري به ڏنل هجي جيئن۔ Power supply 9v Small Switch on/off Speaker 16 Ohm 25 W Audio Transformer Transistor 2N3904 Capacitor Ceramic 0.047uF Resistor 10K Resistor 3.3K
