This morning I featured the Little Professor “electronic calculator” by Texas Instruments on episode 23 of #KnickKnackYack in the #MathShack.

It was so cool and so much fun, I wanted to share it here.

If you’re old enough, you might remember having one of these. Or coveting it because your friend had it.

And if you’re geeky enough, you might remember actually playing it.

You can find the vintage Little Professors here or buy a fancy new Solar Little Professor from TI here. And you can share this on Twitter, Facebook and even Pinterest!

I do #KnickKnackYack in the #MathShack live every weekday morning at 6am EST on Periscope. I share the random knickknacks accumulated through years of math blogging. Sometimes on a math object. Sometimes on something totally random. Always with wit, humor and a little math.
