Dear CamBike enthusiasts,

This week, the team got together with some design-savvy citizens to discuss the project at the Makeathon, and ramped up preparations for sensor hub distribution. Read on to learn more! (But before you do, allow us to once more remind you that now’s your chance to get involved in the CamBike children’s workshop:

Meeting the citizens at the Makeathon

This weekend, the very first CamBike Makeathon was held at Cambridge Makespace. There were lots of interesting discussions and sketches of new ideas, and by the end of the day even a real-life induction-charging system. Thank you very much to everyone who came, we hope you enjoyed the day as much as we did!

Graduating from tape to cable tie: designing mounting systems

Before the Makeathon, the team was using tape to attach the hubs to their bikes, a rather cumbersome ‘solution’ to the mounting problem. During the Makeathon, many new ideas for the casing and mounting were suggested, and one brave volunteer took home a cable tie-attached sensor for a first test run.

From improvising with tape on rainy days to generating new ideas for mounting systems and the first brave citizen beta-testing the device!

A farewell to wires: the production of a printed circuit board

We’ve been designing a printed circuit board (PCB) for our sensor hub, which will allow us to pack all our different components into as little space as possible. Our PCB is technically a printed wiring board: the board contains plugs that fit the pins associated with each of our components, and copper wires within the board provide the right point-to-point connections between the plugs, allowing the components to interact in the right way. With the PCB, you will therefore be able to simply plug all components into place to assemble the system, and so there will no longer be a risk of the hub malfunctioning due to important wires coming loose!

What’s next?

This week, we’re working with industrial designer Harvey Bewley ( to come up with a novel vision for the future sensor hub casing.
We’re also planning to assemble devices for distribution, but international shipment issues mean distribution of the hubs is likely to be delayed until at least next week.

Until next time,

The CamBike Sensor Team
