Deploying a positioning sensor at the Singapore Science Centre

This was my first deployment for an installation at my new job and it proved to be a good learning experience.

We had a positioning device deployed at the Singapore Science Centre on which a laser pointer was mounted. We needed to know where the laser was pointing at, at a scene in front of it, so that the screen application can conjure up the appropriate information based on the target being pointed to.

The device has a screen and laser pointer mounted as seen here:

Depending on where you are pointing at, the screen will show the amount of carbon dioxide emitted by a ship, truck, cow, power station etc, on the mounted screen on the device.

This deployment was memorable because I had to crawl underneath the wooden booth full of dust, cobwebs and in pitch darkness to do some wiring and adjustments. So this was when I learnt that a good torchlight is essential. Also, I learnt about the 5 meter limitation of USB cables, beyond which you need a powered extension. I also helped solder the sensors and wire the electronics inside the casing.

All in all, I am glad that my first deployment went well and we were able to troubleshoot and solve problems on the spot as a team, with me as the electronics guy,together with a programmer and mechanical specialist.
