About
The 8th Annual UW-Platteville Holiday Toy Hack is coming on Saturday, November 15, 2025, 1-4PM in the Huff Family Innovation Center in Sesquicentennial Hall. Last year, 68 volunteers from across campus modified 62 electronic toys so that they can be activated with an external switch! Combined with toys from other efforts on campus, we distributed 84 toys last year!
These toys are donated to families, schools, clinics, and others. This enables kids with special needs, who may not be able to manipulate the toys otherwise, to interact and play. Past recipients include Platteville Public Schools, Hiawatha Elementary School, Variety - the Children's Charity of Wisconsin and families reached through The Arc of East Central Iowa , the Empty Stockings Club in Madison, and the Marshfield Clinic. (See the videos below for more info.)
If you would like to request a modified toy for yourself or on behalf of another family or organization, please use this link: https://go.uwplatt.edu/toyhackrequest2025
*Here is a poster (PDF) if you would like to spread the word at your clinic / school / organization!
None of this would have been possible without student volunteers - and we had volunteers from all across campus, who came and learned and/or shared some skills. Volunteers, please use this link to sign up: https://go.uwplatt.edu/toyhackvolunteer
Also making this possible are donations, which are used to purchase toys, tools, wires, connectors, and switches; see UW-Platteville Foundation -- search for Toy Hack Project. (and thank you!)
* Any questions? Please feel free to email Prof. Evensen.
Recipients, past and future, please feel free to contact Prof. Evensen with any feedback.
We are looking to identify individuals and organizations, and the type of toys they would like that would require some adaptive modification.

Educational Background
Dr. Evensen earned his PhD and Master of Science in Engineering Physics from the University of Wisconsin-Madison, and his Bachelor of Science in Applied Physics from Michigan Technological University.
Dr. Evensen's thesis work was in the area of experimental plasma physics and nuclear fusion. While working as a postdoctoral research associate in the Electrical Engineering department at the University of Washington, he worked on automation applied to DNA sequencing.
Professional Background
My more recent research areas include:
- Carbon nanotube-based electronics: self-assembly of semiconducting carbon nanotube films, and application of these to electronics and sensors.
- Automated rotational grazing (video here): funded by the Dairy Innovation Hub, this project tries to automate the movement and tracking of a dairy herd. This has been a lot of fun. This effort with automated rotational grazing is with a local organic dairy farmer. I've enjoyed working with students from EP, ME, EE, CSSE and ITS, and learning about dairy farming along the way!
- Industry 4.0 / Mechatronics / Internet of Things:
- I've been working with several students in our "I40" lab, on advanced automation, including machine vision, robot arms, smart sensors and cloud-based data collection.
- Two students made a tic-tac-toe game with a FANUC robot arm; video is here.
- I've been working with several students in our "I40" lab, on advanced automation, including machine vision, robot arms, smart sensors and cloud-based data collection.
- Also, we've been working with faculty and industry advisors to develop curriculum related to the Internet of Things, and related areas.
- I am continuing research done during my 2021-22 sabbatical with Professor Mike Arnold's Advanced Materials for Energy and Electronics group. My students and I are presently working on nanolithography of graphene nanoribbons.
