Jeffrey C. Dunnihoo is an electrical engineer with over 30 years of experience in semiconductor and system development. A young computer nerd in the early days of 8-bit home-brew computers and Fortran mainframes, Jeff has been awarded several patents and co-authored research papers and the System Level ESD Co-Design textbook. Jeff created SOIC & SOT to help children discover the nuts-and-volts within their toys and tablets, and not just play with them, but experience the adventure of what goes on inside. Jeff is from Texas. He's a rancher, classic car nut, writer of software and fiction (never at the same time), builder, sculptor, inventor and most of all, a husband and dad. Simona M. Ceccarelli has never donned an ESD suit, but she has worn a labcoat for many years. As a professional artist, she now mixes colors instead of chemicals, but the taste for science and technology often leads her to projects that stride art and science. Simona won the 2017 Portfolio Showcase Competition at SCBWI's Europolitan Conference. Simona lives in Switzerland, where she illustrates books and other products for children, raises some of her own and tries to keep the sense of wonder forever alive.
