Blinky Light Assembly Guide
While the Blinky Light Kit does include instructions, sometimes a picture is worth a thousand words! We have assembled this quick visual guide to help you get your first soldering project built and blinking.
A Few Considerations:
Before we jump into soldering this board together there are a few points to consider.
• Soldering irons and solder are extremely hot and will burn you on contact. Be very careful when handling the Soldering Iron and any components that have been freshly soldered.
• When trimming the leads on components flush diagonal cutters can send sharp metal parts flying all over the room. Eye protection is recommended!
How It Works:
The blinky light uses two transistors to charge and discharge a capacitor. Basically the battery charges the capacitor. Once the capacitor is “full” it will discharge through the LED making a nice bright pulse or strobe.
The Parts Needed:
This tutorial will be requiring a few things:
This handy little diagram shows where each of the parts go. Don’t worry if it looks a little overwhelming, we will be going through this step by step!
Soldering The First Component
If you have never soldered before we highly recommend reading this Awesome Comic that illustrates all the basics of soldering before moving on!
We are going to start by turning on the soldering iron, once it is up to temperature we can begin. Lay the board on its back so the resistor is on the table and rest the tip of the iron on the pad and the leg of the resistor. After a couple seconds (this will depend on the soldering iron you are using) push the solder into the pad until a small cone of solder has formed around the leg of the resistor and the pad. The iron can now be pulled away – let the solder joint cool before moving on to the next. Follow the same procedure with the second leg of the resistor.
Test It Out!
If everything is right, inserting 2 AA batteries should start the blinky light up!
