Keep track of your laps in the pool with this Arduino counter

PeterQuinn925 swims for exercise, and to train for the occasional triathlon, but when doing so he often zones out and forgets how many laps he has swam. To solve this problem without spending a lot of money on a commercial solution, he created his own counter using an Arduino Nano and an ultrasonic sensor. The sensor detects when a swimmer approaches, and the system calculates distance based on this, assuming that a lap is roughly 50 yards or meters. This info is announced audibly via a speaker/amplifier using an Arduino speech library and is shown on a 7-segment display.

Recreating Rosie the Robot with a MKR ZERO

While 2020 may seem like a very futuristic year, we still don’t have robotic maids like the Jetsons’ Rosie the Robot. For his latest element14 Presents project, DJ Harrigan decided to create such a bot as a sort of animatronic character, using an ESP8266 board for interface and overall control, and a MKR ZERO to play stored audio effects. The device features a moveable head, arms and eyes, and even has a very clever single-servo gear setup to open and close its mouth.

Giovanni Mascellani: Bye bye Python 2!

And so, today, while I was browsing updates for my Debian unstable laptop, I noticed that aptitude wouldn't automatically upgrade python2 and related packages (I don't know why, and at this point don't care). So I decided to dare: I removed the python2 package to see what the dependency solver would have proposed me. It turned out that there was basically nothing I couldn't live without.
