For context: Cliff, who designs and sells these bottles, is also the guy who busted KGB hacker Markus Hess in the 80s.

EDIT: I just found out that he also offer the Imperfecto Rulers from Theophilus Measure Co[1]. The accompanying video [2] made my day.

I’m not sure that my students appreciated it so much...

Earlier quoted context omitted.

It's a great robot! His remote controller seems a bit cobbled together, but you can easily use a $50 RC controller with a $5 receiver and an Arduino to control whatever you want with 16 channels, it's amazing!

I'm fairly certain his robot was designed and built before Arduino's existed. The barrier to building robots and electronics has come way down in the past 15 years.

Funny you should mention it— I built a line-following system into the forklift, using an Arduino: I put a row of 16 downward pointing leds on the bottom of the chassis; the Arduino sequentially scanned all 16 leds. A photocell detected reflected light from the floor, and fed this into the Arduino’s analog input. In turn, this let the Arduino decide which side of the line it was on, and how much to turn to get back on track.

But odometry proved a bit more challenging, and it turned out to be more reliable (and fun) to simply move it using a RC controller.

I want to show a bit of appreciation for a website that loads in 50ms. Thanks for keeping it simple, Cliff.

That’s because the site has been up and unchanged for about (if not over) twenty years :) It warms my heart to know it’s still up and that Dr. Stoll is still at it.

I finally broke down and ordered one, and an hour later I got an email from Cliff Stoll with a long series of photographs of him packaging my Klein Bottle – including the packaging and invoicing, with my name on it.

Sure — the photos are as much fo me as you. When I make a missteake, I can look at the pix and see how to prevent the goofup next time.

Sigh ... also because I haven’t changed much in twenty years.
