Product Information
Full details
The Whadda WSAK208 'The Monarch' butterfly kit is designed for electronics hobbyists and students looking to learn about digital design principles through a fun, engaging project. Its primary benefit is the visual feedback provided by flashing LEDs that mimic wing movement, offering a rewarding build experience. A key caveat is that good soldering skills are required for assembly, making it less suitable for absolute beginners. This kit features a unique PCB design and uses a clock source and shift register to generate its light patterns.

FAQs
What skills are needed to assemble the Whadda WSAK208 kit?
Good soldering skills are required. Basic knowledge of electronic components and their orientation is also beneficial.
Does the kit come with a battery?
No, the kit requires one 3V CR2032 battery, which is not included in the package.
How do the LEDs create the butterfly wing effect?
The kit uses a clock source and a shift register in a specific configuration to generate the sequential flashing patterns of the 8 red LEDs, mimicking wing movement.
Can I change the flashing pattern?
The flashing pattern is determined by the fixed circuit design and cannot be easily changed without modifying the circuit.
What age is this kit suitable for?
Due to the need for good soldering skills, it is generally recommended for hobbyists aged 12 and up, or younger individuals with adult supervision and assistance.
What are the educational benefits of this kit?
It helps users learn about the basics of digital design, clocking mechanisms, and the function of shift registers through a hands-on project.
Where can I find more information about the design?
Information about the design can be found on boldport.com, as this kit was designed by Boldport.
Troubleshooting
LEDs do not light up after assembly
Check that the CR2032 battery is inserted correctly with the positive (+) side facing up. Verify all soldered connections are secure and that components are not damaged. Ensure the antennae are properly positioned to make contact.
Some LEDs are not working
Inspect the solder joints for the non-functional LEDs. Ensure the LEDs are oriented correctly (usually marked with a flat edge or a shorter leg for the negative side). Test the specific LED with a multimeter if possible.
Flashing pattern is erratic or incorrect
Re-examine the placement and soldering of the shift register and clock components. Ensure there are no solder bridges (unintended connections) between adjacent pins. Confirm the orientation of all integrated circuits.
Antennae do not trigger the LEDs
Clean the contact points on the antennae and the corresponding points on the PCB. Ensure the antennae are firmly attached and have enough flex to make contact when touched.
Pros and Cons
Pros
- Provides an engaging and visually appealing introduction to digital electronics.
- Teaches practical soldering skills and basic circuit assembly.
- Unique and attractive 'butterfly' design.
- Offers a clear demonstration of clocking and shift register functionality.
- Relatively simple component count for an educational kit.
Cons
- Requires good soldering skills, which might be a barrier for complete beginners.
- Does not include the required CR2032 battery.
- Limited to a single pre-defined display pattern.
- The educational aspect relies heavily on user research beyond the kit itself.
Setup, Compatibility & Care
Setup: Assembly requires careful soldering of the electronic components onto the PCB. Follow the provided diagram precisely to ensure correct component placement and orientation. A standard soldering iron and solder are necessary.
Compatibility: The kit is designed to operate with a single 3V CR2032 coin cell battery, which is not included. No software or external computer connection is required for its basic operation.
Care: To maintain performance, keep the PCB and components clean and free from dust or debris. Avoid exposing the kit to moisture or extreme temperatures. Periodically check the battery contacts for corrosion and ensure the battery is properly seated.
