BL2 High Intensity SMT Blinky Kit $17.95
What can be said about a Surface Mount blinky kit? The BL2 is the revival of our classic BL1 blinky kit in a new, modern form! Yes, two
LEDs that blink, just like our original blinky kit that has made us famous! This one, however, is subminiature and designed with SMT
components! Why, you ask? Besides the obvious, a really neat, super bright attention grabbing display, there’s no better way to
learn how to work with SMT components! Don’t worry, we even include spare SMT chips for when you goof up!
When complete, the BL2 provides alternating super bright red and blue LEDs. Runs on 6VDC and includes two LR55 button cells
and a cell holder to mount on the backside of the board. It’s one complete unit! If you don’t want SMT LEDs you can also use regu-
lar T1¾ LEDs (included). If you want to learn what SMT is all about, the BL2 is for you! While you’re at it, you might want to check
out the magnifiers in our tools section, you’ll need them! (You’ll definitely want to keep your reading glasses handy when you build this one!)
✔ Super bright SMT LEDs
✔ Subminiature board, perfect for displays
✔ Operates from 6 VDC with included cells
✔ Learn SMT the FUN WAY!

Alternately flashes two jumbo red LEDs. This is the kit you’ve seen on name badges,
buttons, hats, and toys, but there’s more to it than that! Add a couple of relays and
Christmas light strings and you’ve got yourself a super light chaser just like the theater
marquee. Add a zener diode and make an attention getting overvoltage warning light!
Runs on 3-9 VDC, typically a 9V battery (not included). Used throughout the world as
the first learning kit for students young and old. Measures 1” square.

LED Red Blinky
K I T
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 for a treat too! When you’re all done you end up with a
super bright Blue TeluxTM LED running on 1.5V! But it doesn’t blink you say? Sure it does... just at 140kHz! Requires a single AA battery (not included). Board measures 1.5” x 1.5”.
✔ Run a 3V LED with 1.5V!
✔ Learn about switching supplies!
✔ Super bright Blue LED!

This digital customer “turn” display unit is ideal for busy shops or offices in need of an attractive and handy way to keep track
of customer lines! The large 2.5" (63 mm) display is made up of two extra large digits, created by 56 bright discrete red LEDs.
The counter circuit is based around a Microchip PIC Microcontroller for maximum features in a small package, and includes three on-
board switches for Count Up, Count Down and Reset. A large push button switch that can be connected to any of the three on-board
switches is also included, so you can set it up for easy remote operation (wire not included) so you can put the display anywhere you want!
Last but not least - an optional speaker can be added to the counter so that each time it counts up, a "Ding Dong" chime sound is produced
twice to notify the customers! Supply Voltage: 6-12VDC or 5VDC regulated. Dimensions: 3.70” x 3.85”. From CanaKit. (Start your own DMV?!)
