{"product_id":"night-vision-enhancer","title":"Night Vision Enhancer","description":"\u003cstrong\u003eNight Vision Enhancer\u003c\/strong\u003e green LED-based flashlights are widely used by hunters and other similar activists to light up their way and to alert other hunters of their presence. Greenlight does not interfere with the hunt, as animals are blind or indifferent to green light. Green is also a good night-vision retention color that allows one to distinguish colors such as yellow and red on maps and charts.\u003cbr\u003e \u003cbr\u003eIn the \u003cstrong\u003eNight Vision Enhancer kit\u003c\/strong\u003e component of this flashlight is a 555 timer that is configured as an Astable multivibrator generating a 50 percent duty cycle square wave at approximately 6Hz frequency. Three green LEDs are connected at output pin 3 of 555 Timer. Switch S1 is the main on\/off switch. In normal mode, LM555 IC is disabled by normally-closed (N\/C) push-to-off switch S1 keeping its output low. \u003cbr\u003e\u003cbr\u003eAs a result, all LEDs (D1, D2, and D3) glow continuously with this \u003cstrong\u003eGreen Light Kit\u003c\/strong\u003e. On the other hand, when S2 is depressed, LM555 timer IC is enabled and all LEDs start flashing. You can also use this flashlight as a signal lamp. Flashing frequency can be varied by changing the value of the capacitor.\u003cbr\u003e\u003cbr\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eBlock Diagram\u003c\/h3\u003e\n\u003cdiv style=\"text-align: start;\" id=\"p_info\"\u003e\u003cimg alt=\"Night-Vision-Enhancer-block-diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Night-Vision-Enhancer.jpg?v=1632822970\" 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 width=\"800\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/8zklJHDB5w4\" 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\u003cbr\u003e\u003cbr\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" 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\u003cbr\u003e\u003cbr\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe width=\"800\" height=\"400\" 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":40708869947573,"sku":"LGKT042","price":299.0,"currency_code":"INR","in_stock":true},{"title":"READY TO USE KIT","offer_id":40708869914805,"sku":"LGKT042_R","price":449.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/products\/night-vision-enhancer-mini-project.jpg?v=1632823133","url":"https:\/\/kitsguru.com\/de\/products\/night-vision-enhancer","provider":"KitsGuru","version":"1.0","type":"link"}
