This weekend I have been working on a test circuit for one of my designs amongst other things. I bought an ultrasound distance sensor and some RGB LEDS to create a test circuit for my flashing light design, just to see if the idea would in fact work. Though it took quite a bit of tweaking and time to get it working, I have actually got it working, with the LEDs glowing green if there is nothing within 2.5 metres, then yellow if there is something between 2.5 and 1.5 metres away then flashing red if there is something closer than 1.5 metres away from the sensor.
I have also attached two RGB LEDs to my cycle helmet’s sun-visor, eye width apart, glowing green. I have done this as a test to see how the public reacts to glowing eyes on a cyclist, especially at night where they act in replacement for my facial features. Overall it has been quite interesting to see how much more attention I got, from pedestrians and drivers. I feel that this will be an interesting point as it shows that drivers take far more notice of cyclists with different colour lights located in different locations to normal.
