Why I Designed the LED American Flag Kit

​

My LED American Flag isn’t about mass production — it’s about learning. It’s the perfect kit for anyone who wants to understand, the mechanics of soldering and an introduction to electronic components, and basic electronic theory firsthand.

​

Beyond teaching you the mechanics of soldering, my mission is to help you think like an Electronics Manufacturing Engineer. That means understanding why a circuit board can be great for learning at your kitchen table but a total nightmare on a factory floor.

 

Why This Kit Stands Out by Design

​

What makes this kit special isn’t its difficulty—it’s its ease of soldering, troubleshooting and repairability.​

Why My Soldering Kit Is Different —

I Specifically Designed the Kit for Hand Assembly & Soldering, Not Factory Assembly

​1. Mixed Technology Components:
My soldering kits use a mix of through-hole and surface-mount components. This introduces builders to both traditional through-hole soldering and modern surface-mount techniques in one project.

 

2. Single-Sided Circuit Layout (No Plated Through-Holes):

All circuitry is located on the bottom side of the board, and I intentionally avoid using plated through-holes for the component leads. This makes it much easier to remove and replace incorrectly installed or defective components — a major advantage for beginners.

 

3. Hand-Soldering–Friendly Pad Design:

I designed the chip resistor pads specifically for easy hand soldering. One pad keeps standard dimensions to help center and “tack” the resistor in place, while the opposite pad is elongated to provide a larger surface area, making it easier to solder with a traditional iron.

 

4.Enhanced Pad Geometry for Hand Soldering- Hand-Soldering Optimized LED Pads:

For all through-hole LED components, I went beyond the standard circular solder pads typically used for component leads. In addition to these standard pads, I incorporated large rectangular pads with substantially greater surface area. These oversized pads make it much easier for beginners to solder the LED leads securely to the board.

Built In Diagnostics

Each LED acts as a diagnostic tool. In a radio kit, a silent speaker might mean any of 25 parts failed. But with the flag, the LEDs show exactly which section is wrong.

​

Due to the inherent nature of the design, I was able to divide the 266 components into small, logical groups of 6–8 LEDs. The LEDs literally light the way to any problem. If something fails, you only need to troubleshoot that small section — not the entire board.

 

In the worst-case scenario, you can use a method electronic repair technicians call “shotgunning,” where you simply remove and replace all the components in that section. This is easy to do because, unlike most circuit boards that use plated through-holes, I deliberately designed my board without them. Plated through-holes can make it extremely difficult for someone who is inexperienced with soldering to remove defective components.

​

Follow the assembly and troubleshooting guide I provide, and your chances of ending up with a 100% functional flag are extremely high.
