What Is the Gikfun Electronic Hourglass LED DIY Kit?
The Gikfun Electronic Hourglass LED DIY Kit EK1886 is a solder-it-yourself electronics project that creates an animated LED hourglass display. The kit uses a double-layer PCB, 30 white LED blue-ray lights, and an MCU program that controls the hourglass-style motion.
It is made for learners, students, and hobbyists who want more than a plain soldering practice board. After assembly, the circuit displays falling LED “sand” to mimic a real hourglass. You get a finished project that can sit on a desk as a small night-light-style decoration.
This is not a broad programming kit like an Arduino starter bundle. It focuses on assembly accuracy, soldering practice, component direction, and basic circuit understanding.
Who Should Buy It?
Best For
- Beginners who want a guided soldering project with a visible result
- Students learning PCB assembly, LED polarity, and basic electronics
- Hobbyists who enjoy small LED display projects and desk decorations
Skip If
- You want a plug-and-play product that works without soldering
- You need open programming, app control, or custom LED patterns
- You do not already have or plan to buy basic soldering tools
Design and Build Quality
The kit uses a double-layer PCB with clearly marked component locations. That layout helps beginners place parts with less guesswork, although you still need to check LED polarity and component direction before soldering.
The 30 LEDs create the main hourglass effect. When the circuit works correctly, the LEDs simulate falling particles from the top section to the bottom section. The result is more engaging than a basic practice board because you can see the circuit working after you finish.
Build quality depends partly on your assembly. Clean solder joints, correct LED alignment, and careful trimming make the finished board look better and work more reliably. Rough joints, reversed LEDs, or loose connections can cause dim lights, missing lights, or failed startup.
Pro Tip: Test the LEDs with a multimeter before soldering, then place all polarity-sensitive parts in one direction check before applying heat.
Assembly Experience
The Gikfun EK1886 includes an English manual and online PDF guidance. That makes the process easier for new builders, especially when you follow the order of assembly instead of soldering parts at random.
You should expect a hands-on build, not a snap-together kit. The listing notes that you need a soldering iron, solder wire, multimeter, tweezers, and wire cutters. A 30W soldering iron is a practical match for this type of through-hole electronics project.
The LED stage usually takes the most patience. Each LED must sit in the correct position and direction, and a small mistake can affect the final animation. Take your time here, because the visual result depends on even placement.
Setup Tips Before First Use
Start by laying out every component on a clean, bright work surface. Group LEDs, resistors, switches, and other parts before you begin. This reduces the chance of mixing parts or soldering the wrong component into a marked position.
Use the manual as your main guide, and check every part before soldering it permanently. For LEDs and other polarity-sensitive parts, confirm direction twice. It is easier to correct placement before soldering than to remove a part after the joint cools.
After soldering, inspect the board for poor joints, solder bridges, or floating connections. The product guidance specifically warns users to check for false or weak soldering, which matters because one bad joint can stop part of the display from working.
Before You Buy: This kit does not work out of the box. You need soldering tools, a stable 3.3V to 5V DC power source, and enough patience to check LED direction before assembly.
LED Display and Hourglass Animation
The main reason to choose this kit is the finished LED animation. The MCU program controls the 30 LEDs to show an analog hourglass image, with the lights moving in a pattern that resembles falling sand.
The animation is fixed, so you should not buy it expecting advanced programming control. That is also part of its appeal for beginners. You can focus on soldering and circuit assembly instead of coding, firmware changes, or troubleshooting software.
Once built correctly, the display can work as a small decorative light. It is best for indoor desk, shelf, classroom, or hobby bench use. It is not waterproof, and it is not designed for outdoor display.
Power, Controls, and Compatibility
The kit operates on 3.3V to 5V DC power. Use a stable low-voltage supply that matches the manual and listing guidance. Avoid guessing with higher-voltage adapters, since overvoltage can damage small electronic components.
The listing identifies a push-button switch type. The control setup is simple, which suits the beginner-friendly purpose of the kit. You do not get wireless control, an app, or smart-home features.
This kit is also listed as non-cordless. Treat it as a low-voltage electronics project that needs an appropriate power connection during use, not as a battery-powered decorative device.
Soldering Safety and Materials
This product involves heated tools, small parts, and low-voltage electronics. Use basic soldering safety every time you build it. Work in a ventilated area, keep the hot iron in a stable stand, and avoid touching the metal tip or fresh joints.
Because the kit uses small components, it is better for teens and adults than young children. Younger learners should only use it with direct adult supervision and proper soldering instruction.
The board is not waterproof, so keep it away from water, damp benches, sinks, and outdoor moisture. After assembly, store the finished unit where the LEDs and solder joints will not get crushed or bent.
How It Performs in Real Use
For Learning Electronics
The kit gives you practical exposure to through-hole soldering, LED polarity, PCB markings, and basic circuit behavior. You can see how correct assembly turns individual components into a working display.
For Soldering Practice
It works well as a first or second soldering project because the repeated LED placements build consistency. The project rewards careful technique, but it can frustrate users who rush through polarity checks.
For Hobby Desk Display
After assembly, the hourglass animation makes the kit more useful than a throwaway practice board. It can sit on a hobby bench, shelf, or desk as a small LED display piece.
For Classroom or STEM Use
The kit suits supervised school electronics experiments where students learn assembly steps and tool handling. It is most useful when paired with instruction on soldering safety, component direction, and circuit inspection.
Common Mistakes to Avoid
The biggest mistake is installing LEDs without checking polarity. If several LEDs face the wrong way, the display may look broken even when the rest of the board is assembled correctly.
Another common issue is using too much solder. Large solder blobs can bridge nearby pads and cause short circuits. Use enough solder to form a clean joint, then inspect the board under good lighting.
Do not power the board with an unverified adapter. The kit is rated for 3.3V to 5V DC, so a higher-voltage supply can create failure risk. Follow the manual and use a regulated low-voltage source.
