This kit really does work on most major brands of TV! It does just send the 'off' codes via some high brightness IR LEDs, so needs to be thought of as a remote control. It may take up to 120 seconds to scroll through all the codes so please have patience when using it. Also double check with phone camera that you see the purple flashing from the LEDs (as highlighted in the instructions). \u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0943\/8168\/files\/TV-B-Gone_Instructions_v5_merged.pdf?v=1653671266\" title=\"TV B Gone Instructions\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eThe kit instructions are available here\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eThe design files are available here: \u003ca href=\"https:\/\/github.com\/curiouselectric\/TVBGone\" target=\"_blank\"\u003ehttps:\/\/github.com\/curiouselectric\/TVBGone\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003ePlease find the \u003ca title=\"Soldering is easy\" href=\"https:\/\/www.curiouselectric.co.uk\/blogs\/news\/soldering-is-easy\" target=\"_blank\"\u003e\"Soldering is Easy\" guide available here.\u003c\/a\u003e\u003c\/p\u003e","brand":"The Curious Electric Company","offers":[{"title":"Default Title","offer_id":4754309252,"sku":"","price":9.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0943\/8168\/products\/PCB_11.jpg?v=1722852183"},{"product_id":"air-quality-monitor","title":"Air Quality Monitor","description":"\u003cp\u003e\u003cstrong\u003e\u003cspan face=\"Arial, sans-serif\" style=\"font-family: Arial, sans-serif;\" data-mce-style=\"font-family: Arial, sans-serif;\"\u003e\u003ci\u003eBuild your own air quality monitor and contribute to the \u003ca href=\"https:\/\/maps.sensor.community\/#3\/40.00\/15.00\" data-mce-href=\"https:\/\/maps.sensor.community\/#3\/40.00\/15.00\" target=\"_blank\"\u003ehttps:\/\/maps.sensor.community\u003c\/a\u003e\u003c\/i\u003e\u003c\/span\u003e\u003cspan face=\"Arial, sans-serif\" style=\"font-family: Arial, sans-serif;\" data-mce-style=\"font-family: Arial, sans-serif;\"\u003e\u003ci\u003e \u003cspan data-mce-fragment=\"1\"\u003eglobal open environmental data platform\u003c\/span\u003e\u003c\/i\u003e\u003c\/span\u003e\u003cspan face=\"Arial, sans-serif\" style=\"font-family: Arial, sans-serif;\" data-mce-style=\"font-family: Arial, sans-serif;\"\u003e\u003ci\u003e. \u003c\/i\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan face=\"Arial, sans-serif\" style=\"font-family: Arial, sans-serif;\" data-mce-style=\"font-family: Arial, sans-serif;\"\u003e\u003ci\u003eCivic Tech in action!\u003c\/i\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan face=\"Arial, sans-serif\" style=\"font-family: Arial, sans-serif;\" data-mce-style=\"font-family: Arial, sans-serif;\"\u003eThis kit contains all you need to set up your own online air quality monitoring unit.
