SF02 Laser Rangefinder Unable to resist the temptation of the new SF02 Laser Rangefinder

It’s not very often I get to hook up hardware and write some code, but I couldn’t resist the temptation this time. Parallax is currently the only distributor of Lightware’s SF02 Laser Rangefinder. In keeping with Parallax’s approach of having only one or two key parts per category, this one really rounds out our distance sensing selection.

The SF02 is incredibly capable with a 0-40 meter (0-130 feet) range and +/- 1 cm resolution and 12 Hz update. At 40... More

Jessica Uelmen presents at the NSF Workshop Parallax Supports STEM Education at the National Science Foundation Workshop

After USASEF, Ken and I had the honor of attending a National Science Foundation workshop in order to provide industry input for their Research Experience for Teachers (RET) program. RET programs provide teachers with research opportunities in university or industry labs. The teachers then take the lessons learned during their research and integrate it into their classroom curriculum. To goal is to increase awareness in engineering careers for students in grades K-14.

We’d like to... More

Roaming Patriotic Arlos at USASEF 2014 Parallax attends the 2014 USA Science and Engineering Festival in Washington, DC

Two years ago we attended the USA Science and Engineering Festival in Washington DC where we taught 1,500 kids how to solder. In our eyes, the event could not get bigger or better the second time around - boy were we wrong!

This year’s USA Science and Engineering Festival held at the Walter E. Washington Convention Center was a free three-day event expected to draw over 250,000 attendees. Words cannot adequately describe how enormous this convention center... More

Participants of the Greek National Computer Teachers Association robotics seminar with the S2 Introducing Parallax products in the Greek educational community

The Greek educational community has been starting to take robotics more seriously.  Robotics competitions, seminars, and technological festivals and events are some of the steps being taken in this direction. 

Last month the Greek National Computer Teachers Association (annex of Patras) “PEKAP” organized a robotics seminar including various topics like Lego robots, Parallax, and Arduino.  It was a great opportunity for me to introduce Greek informatics teachers to the Parallax... More

The dreaded ‘LED Fan-Effect’. Due to size, it’s impossible to fit round LEDs neatly in the same breadboard row. Round LEDs are SO last season...introducing new rectangular LEDs!

Throughout my development of Stamps in Class Mini Projects and training of teachers and students, I've had one constant pet peeve: the LED Fan-Effect.

The "LED Fan-Effect" occurs when attempting to line up three or more T 1-3/4 circular LEDs in the same breadboard row. The diameter of each of these LEDs is too wide to fit neatly and as a result the LEDs splay across the breadboard. The result is messy and displeasing to the eye, yet unavoidable.

Until now... More
