Who we are?

Our aim is to provide reasonably priced electronic prototyping tools and components for artists, designers, hobbyists and engineers.

Månsteri Store is run by Månsteri (Matti Niinimäki), a media artist and interaction designer based in Helsinki, Finland. The store came into existence out of a personal need. I was buying electronics and parts from many international stores. Never quite getting all the stuff I most often use from one single place. That got me thinking: "Maybe there are other people in Finland thinking the same way?" And now we are here.


The main product we carry is the Arduino board in its many varieties and other electronic parts – such as sensors, actuators etc. – compatible with the Arduino. We also try to offer all basic components and tools for prototyping so you can get everything you need for your project from one place.

Our product catalogue grows slowly and steadily, but we try to only stock items we have personally used and found to be useful in our own projects. This way we can offer items that are high quality and compatible with each other. This allows us also to give suggestions and instructions on how to use them. Many of the product pages have links to projects where we or our clients have used that item. We also try to create tutorials or detailed instructions for most of the items we carry.

If you have a product in mind that you would like to see in our store, please send us a message with the contact form or send an email to: email

Environment & Ethics

We are very concerned about the environmental and health effects associated with the production of electronics, but as a very small player, it is hard for us to really know for certain where our products come from. We try to be as transparent as we can in this matter.

Therefore, we are very proud to be a distributor of Arduino, because they share our concern in this matter. All of the official Arduino boards manufactured by Smart Projects – Uno, Mega 2560, BT, Mini – are made in Italy where the workers are reasonably paid and work in a safe environment.

If we become aware that a product we carry has been manufactured in working conditions that seriously put the environment or the health and safety of workers to risk, we will stop selling such an item.

All of the products we sell are RoHS compliant.

We also try to minimize the packaging and use recycled materials whenever possible. All components sensitive to static electricity are packed into antistatic materials, otherwise we try to avoid plastic as much as possible.

Thank you for shopping with us,
