It is built entirely without soldering using a 12-way 3A terminal strip. This is somewhat better than the simpler versions available elsewhere, in that it has two additional output driver transistors. This allows you to flash more than two little LEDs, or use proper bulbs as shown. All the build information is provided online so that easy updates can be added. The build information is full and detailed, and there's a full electronic explanation provided with oscilloscope screen-shots. Three different resistor values are provided for different flashing rates. If you're looking for a school science project which you can make in a hurry, then look no further. In addition you will need four AA batteries, a small screwdriver, some wire cutters, small pliers, and some means of stripping the insulation from the wire in addition to the above.\u003c\/p\u003e\n\u003cp\u003eHere is the link to the instruction pages:\u003cbr\u003e\u003cbr\u003ehttps:\/\/www.usefulcomponents.com\/main_contents\/projects\/flip_flop_1\/flip_flop_1.html\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e Tried and tested design \u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e Requires no soldering \u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e All electronic parts included excepting batteries \u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e Instant school science project suitable for ages 14 and above \u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e Fully detailed instructions and technical documentation provided online \u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HJW Electronics","offers":[{"title":"Default Title","offer_id":58499175285120,"sku":"CBFF-1","price":12.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2136\/1280\/files\/cbff_1_pack_w.jpg?v=1784558589","url":"https:\/\/shop.usefulcomponents.com\/products\/flashing-light-flip-flop-kit-with-full-online-instructions-cbff-1","provider":"HJW Electronics","version":"1.0","type":"link"}
