Whadda is a Premium Maker Brand by Velleman Group nv that produces electronics projects for hobbyists, or as we now call them, makers. Creating these electronics projects has been Velleman's main activity for more than 20 years! So since 2020, we at Velleman Group nv have decided to update its exciting electronics brand into Whadda.

Whadda’s projects will revolve around the following four main skills; soldering, electronics, coding, and mechanics. This means, that each DIY project will focus on at least one of these skills. We even designed a little mascot named Whaddy! Whaddy will help out novice Makers to find their way in the world of electronics. He'll spread around tips and tricks, and teach you a thing or two about our four main skills.

Each project is also accompanied by an illustrative manual that is available in at least 5 languages. This manual can be found online, on the product page of the project in question. Simply click on the manuals tab to find it. Only our soldering kits for kids include a manual on paper.

Each day, we strive to post tutorials, projects, and videos about our projects as well. This way, Whaddy can guide and teach you in the best way possible!

Are you looking to partner up with Whadda? Do you run a STEM academy, a makerspace, a FabLab, … or are you a teacher? Then be sure to contact us!
