{"product_id":"timer-machine-gun-circuits","title":"Timer Machine Gun Circuits","description":"The \u003cstrong\u003eTimer Machine Gun Circuits\u003c\/strong\u003e battery of 9V is connected to the speaker as well as PNP transistor BC557. Supply of 9V is given to pin no 8 and pin no 4 of 555 timer IC which are internally connected to each other. Here 555 timer IC works in astable mode. At pin no 5 and pin no 2, a capacitor of 10μF is attached. 3 electrolyte capacitors are also used of 10μF.\u003cstrong\u003e Timer Machine Gun \u003c\/strong\u003eTwo resistors are used of 100K and 33K. In which one resistor is attached between transistor and pin no 1 while the other is connected between pin no 2 and output pin no 3. The one end of the speaker is connected to capacitor C4 while another end is connected to capacitor C5. \u003cbr\u003e\u003cbr\u003eWhen the \u003cstrong\u003eTimer Machine Power Supply\u003c\/strong\u003e is on, the circuit starts working, which means the transistor will start work but since it is a PNP transistor it will work only when it gains low pulses. When it gains low pulses, the supply is reached to pin 8 of 555 timer IC which works in astable mode. Capacitor C5 act as a bypass capacitor which allows only the same frequency sound which leads to producing a sound on the speaker. The sound produced on the speaker is just like the sound produced by the machine.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions (cm) L x W x H : 15 x 12 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 50\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eProduct Video\u003c\/h3\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/XqZOXAoF0XA\" height=\"409\" width=\"727\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/fXzHD0gv4S8\" height=\"409\" width=\"727\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/Pjsoq-ZejRM\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF","offer_id":40708941840565,"sku":"LGZK007","price":149.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/Timer-Gun.jpg?v=1634384573","url":"https:\/\/kitsguru.com\/fr\/products\/timer-machine-gun-circuits","provider":"KitsGuru","version":"1.0","type":"link"}
