Hey Volthaus Lab,

A friend of the lab who bicycles to work has asked if something could be designed for help with clearing the road of various animals. A device triggered by a small button on the handlebars. He also pulls a small trailer to which the device and a battery could be placed for power. Lights and siren with 433MHz com from switch to unit.

Imagine an incident like this happening on pavement in the dark.

UPDATE Nov 9, 2016:

The components are coming together. I reflow soldered six three-watt white LEDs to heatsinks and wired them up in parallel to 18650 3.7 volt Li-Ion battery and am getting fair amount of brilliance. And also bought two full fledged sirens from AllElectronics  I did make a couple of Arduino based sirens with a small speaker and they were not what I had in mind. With the new sirens this is shaping up to be quite a road clearing device.

The on/off transmitter button will be housed in a small container that I’m planning to have mounted using velcro possibly. For communication 433MHz RX-TX modules will more than transmit the signal the few feet from the handlebars to the actual device.
