Construction

When creating electronic projects, you often think of microcontrollers, sensors or wiring first. However, a solid construction is just as important. Without a solid base, even the smartest design will not work properly. The mechanical structure keeps everything in place. Whether you are building a robot arm, making a measuring station or developing a housing for a Raspberry Pi. The right components ensure reliability, stability and a neat finish. Construction is indispensable within the prototyping process. Electronics alone are rarely enough. Everything must be secured, protected and sometimes even able to move. This is where components such as spacers, screws, mounting rails and housings come into the picture. They make your design safe, sturdy and flexible. Especially with prototypes that are modified several times, good construction prevents frustration. You work faster, neater and prevent errors or damage.

The function of mechanical parts in a good design

Mechanical parts come in many shapes and sizes. Think of spacers that keep your printed circuit board at a safe distance from metal surfaces. This prevents short circuits. Or housings that protect your electronics from dust, bumps or moisture. At the same time, you can easily reach the buttons and ports. For makers who often modify projects, modular systems such as MakerBeam are a godsend. With these, you can attach parts without gluing or drilling.
For mounting, use standard sizes such as M2.5 and M3. These fit perfectly with well-known development platforms such as Arduino and ESP32. Thanks to the uniform sizes, you can easily replace or move components. This makes your construction clear and professional.

MakerBeam: flexible construction with precision

A widely used system among makers is MakerBeam. This consists of aluminum profiles, corner pieces, bolts and nuts. The system is specially designed for small constructions such as prototypes, robotics or test setups. The big advantage is the reusability. You can quickly adjust the frame without it becoming less sturdy.
MakerBeam is particularly useful if you often need to make adjustments. Think of a sensor that you want to point in different directions. Or a small robot frame that you want to expand further. The precise dimensions and the wide range of accessories allow you to build quickly, without sawing or gluing. Everything fits together seamlessly.

Making smart choices when building

You choose the right components based on your application. Do you want to place a sensor on a mast? Then use sturdy spacers and a wide base. Do you work with multiple printed circuit boards? Then mounting plates or rails keep your system organized and easily accessible.
Also consider the material of your components. Plastic spacers are light, insulating and easy to process. Metal versions are stronger, conduct electricity and are suitable for grounding. When choosing a housing, more is important than just size. Consider access to ports, space for ventilation and protection against water or dust.
Preferably use screw connections instead of glue. This allows you to easily detach and adjust components. This saves time during testing and prevents waste.
