There was a series of YA/kids books I read in grade school (late 70s, early 80s) about a science curious boy who would get into a series of adventures with his friends. I think these adventure were usually prompted by an eccentric uncle who would send said kid something in the mail.
At one point, the uncle sent the kid a home computer but because of the time frame and technology being what it was. it ended up being a bust for the kid, because it actually made his homework harder (it would do math for him but because he had to show his work, he ended up having to do the math anyway, I'm sure there was a lesson there).
At one point the kid ends up befriending a nearby local scientist and through a series of very plausible circumstances (sarcasm for those who don't know me), ends up flying in a home made rocket ship to a far away planet populated by sentient dogs (think "Planet of the Dogs"). The dogs were friendly and he gradually was able to speak their language and be accepted in their society. At one point, he teaches the dogs how to play baseball, which was weird because the smart dogs would catch the ball in their mouth and then throw it with their paw (I question how that could happen but that's the least of my issues).
What was strange about this particular book in the series was, up till then, there was nothing fantastic or science fictiony about the series. And at the end of this book, the series went back to normal, with the kid being in a series of normal (although improbable) set of adventures.
Even though I remember reading these in the 70s/80s, something makes me think these were written in the 60s, based on my memory of the writing. Can anyone help me with this memory, which I am convinced is real?
