“I was asked to give a workshop regarding sound art in Super Public Art School that is held at Titanik-gallery in Turku. As I have been working lately with microcontroller based sound synthesis I searched for a good topic around this area. So the idea to build pocket sized audio players came a long.”

Now it’s time for our second bonus lessons on PyroEDU’s Digital Course. We’ll finish the course off by looking at 4000 Series Logic Devices. Here’s a quick intro of what this PyroEDU lesson is all about:

This bonus lesson dives into the more advanced 4000 logic IC’s available to us as designers and looks specifically at 3 interesting IC’s. The experiment for this lesson is to build a 4-bit single IC counter.

“Walleye is an interactive light installation which engages users in temporal gestural and bodily play. It generates temporal light propagation patterns, or a large scale very low resolution pixilated image (depending on how you look at it) based on the realtime movement of visitors in the space.”

“With this I have an autonomous robot based on the FRDM-KL25Z board and a chassis from Pololu. It performs line following and maze solving, and can be controlled by a remote shell or controller unit (e.g. with an accelerometer).”

“The story behind this experiment was to investigate the average wind speed to motivate a future wind turbine project. A commercial logging weathers station cost much. So this is an attempt to build a good alternative cheap solution.”

“If you look at the code for our electronic dice then you will see that it is just a counter. It counts up while you press a button. Why is this a prefect dice? It’s a dice because microcontrollers do operations in ?s and humans are unable to control pushbuttons and time with the precision of ?-seconds.”

“A while ago I got my hands on some old split-flap displays from a train station. Yesterday I finished driver circuits for 8 of the segments. It was only just in time to also quickly implement a clock algorithm for an extraordinary clock to display the turn of the year. Don’t miss the movie at the end of this posting.”

Now it’s time for our two bonus lessons on PyroEDU’s Digital Course. We’ll start by looking at 7400 Series Logic Devices. Here’s a quick intro of what this PyroEDU lesson is all about:

After you have mastered the digital fundamentals you are ready to grow and move to the more complex areas that exist. This bonus lesson dives into the more advanced 7400 logic IC’s available to us as designers and looks specifically at 3 interesting IC’s. The experiment for this lesson is to build a knight rider LED circuit.
