The Adventures Of Professor Ventura, Bart And Clarke [PDF ebook] 

Imagine a crazy but very well-intentioned teacher, who knows about technology and other sciences and his two students involved in the greatest adventures and all this in a small town where a technical school operates. Using electronic technology from different periods, from improvised material to microcontrollers and other resources, they get involved in funny problems, solve mysteries, and even solve community problems. This is Professor Ventura with his students Bart and Clarke. In this book, I chose some of the funniest adventures I wrote since when I imagined the characters in the 60’s and then modified them to be part of a series, published in an 80’s magazine and later on my website, with an evident modernization.
