My husband has been on the faculty at the University of Minnesota in Duluth for 30.5 years. He teaches in the Electrical Engineering Dept. He will be retiring in January, 2019. I recently asked him what his favorite piece of equipment is in his EE lab. His quick response was "the microprocessor." My husband also enjoys doing jigsaw puzzles. A friend had told me about their experience with Piczzle. I couldn't think of a better Christmas gift for my husband! A 1000 piece puzzle of his prized microprocessor. Thank you for your great work in creating his gift! I can't wait to see him working on it on our dining room table after the Holidays!
