Super bright Blue LED
Long battery life
Electronic Kit - Assembly Required
More than 30 years ago we came out with our ever famous BL1 Blinky kit. Thousands and thousands were built teaching people exactly how LEDs and transistor circuits work. Now we're going one step further! The LSW1 will show you how to light a 3V LED with a single 1.5V battery! The circuit is actually a very unique "switching power supply" which steps up the 1.5V battery voltage to around 5VDC! If you're new to switching power supplies this is the perfect little kit to get your feet wet! If you're a serious hobbyist and want to see the neatest little circuit then you're in store for a treat too! When you're all done you end up with a super bright Blue Telux LED running on 1.5V! But it doesn't blink you say? Sure it does...at 140kHz! Requires a single AA battery (not included). Board measures 1.5" x 1.5".
