Posted on June 16, 2020 by R-B Leave a comment

When it comes to STEAM (Science, technology, engineering, art and math) education, the Raspberry Pi is perhaps the most affordable, powerful, and versatile learning tool for all ages and skill levels. The versatility of this little computer comes from its incredible interconnectivity feature that offers direct connection of sensors and electromechanical components, thereby allowing the users to learn embedded hardware and programming in a very simple and engaging way. Since it first came out in 2012, the Raspberry Pi has been the most adventurous tool of teachers in the classroom to foster learning, awareness of computer programming, and extend the

Acme traffic light restoration

Posted on July 19, 2018 by R-B One comment

The Southern California Transportation Museum is one of the largest private transportation museums in the United States. We are privileged to have among our artifacts a set of Acme traffic lights. This type of traffic signal was deployed in the Los Angeles area in the 1920s and 1930s. This was the time when every city was experimenting with different types of traffic signals. Later the Automobile Club convinced everyone to adopt the three-light signal they use today. During the brief time they were in use, the ACME traffic light became the favorite of the Hollywood cartoonist so, that’s why you see them all over the movies.

Marcel describes in this Instructable how he gave a new life to his old radio by powering it with an Raspberry Pi that streams various radio channels over the internet. He kept the functionality of the original tuning knob for tuning to radio channels. The RPi speaks up the name of the tuned channel in English or in your own language, as configured. The radio also features a safe-power-off button for proper shutdown of the RPi. He wrote the software for the radio in Python that runs automatically upon boot.
