When switched on, the l.e.d. gradually changes colour over about 30 seconds and then the sequence repeats. Placing a cut-glass tea light holder or tumbler over the l.e.d. enhances the display.\r\n\r\nPlease have a look at a working \"L.E.D. Surprise 1\" circuit on the Irby Electronics YouTube channel. \r\n\r\nWhen this circuit was tested, a set of Duracell Plus Power batteries was still producing a good light output after 140 hours of continuous use.  \r\n\r\nThe circuit is made on foam board (approx. 11 cm x 7 cm) and requires 3 x AA batteries (not supplied). Just 3 joints are needed to make this circuit and these joints can be made by simply twisting wires together and then crimping the connection with pliers. Soldering, however, makes a better electrical joint. Please see Kit 7 for an alternative version of this circuit constructed on track board.\r\n\r\nThese tools are needed to make this kit (not supplied):\r\n        small pliers for bending component leads,\r\n        slotted screwdriver for securing foam board to wooden base,\r\n        small, low power soldering iron, e.g. 15 watt, 18 watt or 25 watt (only if soldering is to be attempted).\r\n\r\nPlease read the safety warning in the About Irby Electronics section before ordering a kit.\r\n","brand":"Irby Electronics","product_id":6872538,"availability":"in stock","quantity":4,"product_expiration":"2026-05-09T10:07:02+00:00","images":["https://imagedelivery.net/0ObHXyjKhN5YJrtuYFSvjQ/i-6b384e74-4732-45ed-944a-e87bb2d04bd0-Kit-1-Surprise-1-Irby-Electronics/public","https://imagedelivery.net/0ObHXyjKhN5YJrtuYFSvjQ/i-ae4318e0-72e9-4da8-a3bb-f0d4ab29a200-Kit-1-Surprise-1-Irby-Electronics/public","https://imagedelivery.net/0ObHXyjKhN5YJrtuYFSvjQ/i-7e1ac5d5-54fb-448d-b152-5ebce4ab52bf-kit-1-surprise-1-irby-electronics/public","https://imagedelivery.net/0ObHXyjKhN5YJrtuYFSvjQ/i-9466b3a9-3594-42e8-a219-46e595fc10c3-kit-1-surprise-1-irby-electronics/public","https://imagedelivery.net/0ObHXyjKhN5YJrtuYFSvjQ/i-187f2a36-777c-417a-a2e0-e259c749442d-kit-1-surprise-1-irby-electronics/public","https://imagedelivery.net/0ObHXyjKhN5YJrtuYFSvjQ/i-50161f00-c90e-4875-b8b7-0301e11ff33b-kit-1-surprise-1-irby-electronics/public","https://imagedelivery.net/0ObHXyjKhN5YJrtuYFSvjQ/i-01ab38e6-76ba-468f-ab82-493a55bc3490-kit-1-surprise-1-irby-electronics/public","https://imagedelivery.net/0ObHXyjKhN5YJrtuYFSvjQ/i-f45d8271-ea26-4a5e-899e-e60b52fad439-kit-1-surprise-1-irby-electronics/public","https://imagedelivery.net/0ObHXyjKhN5YJrtuYFSvjQ/i-e142c3fd-9314-4166-b2eb-d999bbdf3dab-kit-1-surprise-1-irby-electronics/public"]}
