Satellite Sun Sensors

Finland launched her first two satellites in 2017. I designed and built the sun sensor prototype
with Tero Karvinen. Sun sensors are a part of the navigation subsystem in both satellites.
At the time of publishing the peer-reviewed article it was the smallest and the most inexpensive
sun sensor available. Final packaging and test campaign was done by Tuomas Tikka.

Read the peer-reviewed journal article "IoT Rapid Prototyping Laboratory Setup"
published in Journal of Small Satellites (JoSS).


Framework for selecting sensors for a novice use

Using breakout physical computing toolkits, such as Arduino, has become a common practice of both engineers and non-engineers
alike. While these development platforms solve many low-level challenges, getting started with embedded system prototyping may
seem overwhelming for novices. Choosing novice friendly sensors can make a substantial difference.

Read the peer-reviewed journal article "Choosing novice friendly sensors"
published in International Journal of Electrical Engineering Education (IJEEE).

Between 2013-2017 I worked as a software development director
in a large-scale situational awareness presentation system
development project produced for the Finnish Defense Forces.
The value of the whole project was approximately 10 million €.

Robot was a part of our presentations in Maker Faire San Mateo, California
(Evolution of a Robot - Learn to Prototype Anything) and in Mozilla
headquarters, Silicon Valley (Prototyping Open Source Robots).
ZenBot was made with Tero Karvinen and Ville Valtokari.

ZenBot - a mind-controlled robot

I'm a Doctor of Science (Technology) from the Department of Automation and Systems Technology,
School of Electrical Engineering, Aalto University. My doctoral dissertation explores which tools
and processes would lower the threshold of designing embedded systems, enabling non-engineers
and novice engineers to turn their innovations into working prototypes in such way that the
workflow allows experimentational prototypes to evolve into deployable embedded systems.

Great teaching tool for introducing DIY with Arduino or Raspberry Pi. It gives you a good intro to building these systems to interact with the physical world around us. If you like hands-on you will use this book. -Charles Rogers

A Mighty Find [..] The beauty of this book is in its ability to catch and hold one's interest: there are dozens of projects requiring a wide range of ambition (notice I didn't use the word 'expertise'), each contributing to the store of knowledge you'll acquire in the use of the Pi, in computing and in electronics. This is properly a hands-on book. I'm a teacher researching curriculum for my students, and the title sums up my view. They will eat this up like Kibbles and Bits. Score! -STEM Teacher

Use this book for projects. Great book. -Dana Dickinson

Love this one. -honesavanh T.

Makes it a natural starting point for anyone experimenting with robotics, automation and control. -Rick Cook

Talking as a person who is not a robotics specialist I have to say I really liked this book. I thinks it is comprehensive and easy to follow. It is well structured, first the mechanical part and then the software part. And I think it is very interesting that they tell us about how to "recycle" materials to build it. -avid Fernández

The instructions are well structured and clearly written. Anyone should be able to follow them. Little tips here and there make book a refreshing read. I would recommend this book for anyone interested in Arduino, tinkering and brainstuff! -Panu Koskela
