** REPOSTING THIS JOB, WITH A GREATER FOCUS ON THE ELECTRONICS DESIGN AS OPPOSED TO FORM FACTOR**
I'm looking for someone to design an battery-powered array of bright white LED lights (or a single, powerful LED), with the end goal of the electronics fitting in a casing (which I will build based on the electronics) approximately half the dimensions of an iPhone, along with a wireless remote control on/off switch (herein referred to as the "Device").
The Device should be bright enough to be seen clearly from approximately 50 to 75 meters away in dark conditions. The Device will be activated (i.e. turned on and off) via the remote control, with the default switch position being off. The remote control should be approximately the dimensions of an iPod Shuffle (w:4cm x H:4cm x D:[url removed, login to view]), with a single, large button on the front, and a tiny, red LED light in the corner to indicate that the button is active. When a user holds down the button on the remote, the light/lights will turn on, and when the button is released, the light/lights turn off (i.e. the lights only come on while the button is being held down by the user, but they cannot remain on without this continuous pressure). The remote and light array should be able to operate wirelessly within a range of approximately 7.5 meters. The batteries should be replaceable and of a type easily available, but long lasting (maybe something like a watch battery, but I'm open to suggestions).
Ideally you'd provide an electronics design/schematic which I could take to a manufacturer, plus have you build a working unit that I can test to see if it operates correctly. The design of the board and lights should fit into the dimensions I outline above (I will work on the plastic casing after I have the electronics done). This should be a very simple circuit to build, so the schematic should be easy to understand.
I will also need to consult with you on material costs. Ideally you could present a few different material options and I choose which group of parts makes the most sense for my needs vs. cost to build (e.g. multiple weaker LEDs vs. a single powerful one).
I can provide detailed drawings of the intended design to whoever this project is awarded to, and help fill in any missing details on how this Device should look and operate.
