DIY electronics experiment kit parts

thingiverse

I was searching for an electronics experiment kit for my 11-year-old daughter, but what I found was disappointing - a few parts and projects with no way to expand on it. So, I took a look at my own collection of components and thought about how to turn them into a fun and educational kit for her. One potential solution was using a breadboard, but that seemed too complicated, so I came up with the idea of creating wooden boards with switches, a bell, a buzzer, some lamps, LED units, and more. I used the same little Dupont cables I use in my own breadboard projects to connect the parts and a battery pack with a switch on it - it all worked seamlessly. After a short while, we needed diodes, resistors, capacitors, and transistors, but they wouldn't fit well on the small wooden boards. So, I designed some 3D-printed components to hold these electronic parts and their connectors. I created various pin configurations, including two-pin, three-pin, and four-pin designs. Next, I cut short wires with female connectors and soldered them to the components. Then, I glued the components and connectors together using a hot glue gun. To make it even more engaging, I added little stickers on the boards that explained each component's function and value, and for transistors, I included labels indicating the EBC pins. Finally, I used velcro tape to attach the parts to the board, making it easy for my daughter to create her own electronic experiments. To share this idea with others, I created a Dutch-language webpage featuring simple schematics, allowing anyone to build their own extendable electronics experiment kit for kids: https://www.heinpragt.com/techniek/robotica/elexparts.php Print Settings: Printer: Prusa I3 Rafts: No Supports: No Resolution: High Infill: High Notes: To make the small parts strong, use high infill and smooth them out with high resolution. I designed these components as usual using FreeCAD.
