{"product_id":"spy-ear-audio-amplifier","title":"Spy Ear (Audio Amplifier)","description":"\u003cstrong\u003eAudio Amplifier Binoculars\u003c\/strong\u003e can improve your eyesight and this personal sound enhancer circuit can be used for listening. This kit \u003cstrong\u003eSpy Ear\u003c\/strong\u003e light-weight gadget produces an adjustable gain on sounds picked up from the built-in high-sensitivity condenser microphone. So you can hear what you have been missing. \u003cbr\u003e \u003cbr\u003e A \u003cstrong\u003eSmall-signal Amplifier\u003c\/strong\u003e is built around transistor BC547 and the related parts amplify the sound signals picked up by the condenser microphone (MIC). The amplified signal from the preamplifier stage is fed to input LM386N (IC) through capacitor and volume control. A decoupling network comprising resistor and capacitor provides the preamplifier block with a clean supply voltage. The LM386N power amplifier can safely drive a standard 32-ohm monophonic headphone\/earphone.\u003cbr\u003e \u003cbr\u003eIn this \u003cstrong\u003eKit Spy Ear Audio Amplifier\u003c\/strong\u003e, IC LM386N is designed for operation with power supplies in the 4-15V DC range. It is housed in a standard 8-pin DIP package, consumes a very small quiescent current, and is ideal for battery-powered portable applications.\u003cbr\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003e\n\u003cbr\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv id=\"p_info\" style=\"text-align: start;\"\u003e\u003cimg alt=\"audioamplifier-using-lm386\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/spy-ear-block-diagram.jpg?v=1632554946\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003c\/div\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 : 20 x 15 x 5\u003c\/li\u003e\n\u003cli\u003eWeight (gm): 200\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 height=\"400\" width=\"800\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/6bLMvzoLMAs\" frameborder=\"0\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe height=\"400\" width=\"800\" src=\"https:\/\/www.youtube.com\/embed\/6rmErwU5E-k\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe height=\"400\" width=\"800\" src=\"https:\/\/www.youtube.com\/embed\/Fp37DPZVdRI\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"DO IT YOURSELF KIT","offer_id":40708843569333,"sku":"LGKT009","price":449.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE KIT","offer_id":40708843602101,"sku":"LGKT009_R","price":699.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/Learning-kits.jpg?v=1632560015","url":"https:\/\/kitsguru.com\/fr\/products\/spy-ear-audio-amplifier","provider":"KitsGuru","version":"1.0","type":"link"}
