Synth Bike 3.0 produces tunes with 12 Arduino Nanos

After building a bicycle that could travel across town while making music, Sam Battle now taken things in a different direction. Synth Bike 3.0, which will be on display at the Science Center Dublin until September, is set up on a training fixture so that you can pedal it indoors rain or shine. This version also features a simplified control panel on the handlebars, allowing it to be played by anyone at a tempo controlled by the rear wheel’s speed.

Battle’s YouTube channel is named “LOOK MUM NO COMPUTER” however, this apparently doesn’t count microcontrollers. Hidden in the externally clean-looking handlebar groove box is a total of 12 Arduino Nano boards, along with a maze of wiring, strip circuit boards, frequency central PCBs, a SparkFun WAV trigger, and some other electronics. There’s even built-in speakers on the sides to output the created sounds.

Be sure to check out Synth Bike 3.0’s New Atlas write-up for more info on the project.

What Is A Wired Bike?

Some people think of the Industrial Internet of Things (IIoT) as the comprehensive use of multiple sensors on complex machinery, heavy equipment, or remote turbines to stream vast data in real-time via the Internet.

While some IIoT applications are quite complex, others can be as simple as riding a bike. That’s what representatives from SAP and Hewlett Packard Enterprise (HPE) are demonstrating with their “Wired Bike” concept.

They have outfitted a mountain bike with multiple sensors that measure vibration, wheel rotation, lateral movement, and other data points that detect the bike’s functionality. The information gathered from these sensors automatically streams in two ways:

  1. Real time. Data flows through an HPE Edgeline server into:
    • A 3-D visualization of the bike that tracks the bike’s movement. This could allow people in another location to monitor the bike and the data it is generating.
    • An augmented reality iPad app, showing sensor data overlaying a picture of the bike, which could be used by a service engineer in the field.
  1. Real time and history. Data streams as outlined above, plus data is also collected in SAP HANA via the SAP HANA Cloud Platform (HCP):
    • A simple voice interface can access historical data.
    • The collected data could also be used for predictive bike maintenance.
    • Native iOS apps could also be built to tap into the data in the HCP.

Endless applications of the IIoT

The ‘wired bike’ is only a demonstration, but the essential idea is that it is just another ‘thing’ that can be connected and monitored via the Industrial Internet of Things.

This idea can be carried over into multiple uses and industries, including aircraft assembly, where there are many critical maneuvers throughout a long manufacturing process (18 months on average).

All of the information needed for manual intervention and reference materials could be combined with a smart tool to automatically configure the tool’s settings to the work required. For example, the information stored in an SAP ERP system could automatically select the proper tool bit and torque required for a sequence of steps in the production process. This could speed up work and reduce the overall manufacturing time required, while reducing the risk of error in the process.

The wired bike is just the beginning. Think of where else we could go with the IIoT.

Make an “analog” bike speedometer with Arduino

As Maker Alex Gyver points out in his video, Chinese bike computers are quite cheap, but “why not?” It’s a great question, and one that motivates many of the hacks seen here, including his mountain bike speedometer.

Although he could have simply used a numerical display to show how fast his bike was going, he instead employed a small servo to point to the speed like an analog gauge. The custom speedometer is based on an Arduino Nano, and wheel revolutions are measured by a magnetic and Hall effect sensor.

This may seem like a silly project, but if you need to take a very short glance at something, analog gauges tend to be much easier to read than digital. Perhaps this concept could be quite useful! You can see exactly how to make this hack on Instructables and in his video here with a few action shots. Code can be found on GitHub if you’d like to check that out as well!
