This is the helmet.\u00a0 Every attempt will be made to embed the electronics.\u00a0 There will be some components that will be mounted externally.\u00a0 The integrity of the structure must provide protection to the rider in any event.<\/li>\n<\/ul>\n<ul>\n<li>Lighting &#8211; There will need to be headlamp, either fixed or removable for safe night operation.\u00a0 In addition, there will also need to be visibility lights either in the rear or sides of the helmet.\u00a0 These can be fixed or removable.\u00a0 The servicing of the lights should be considered in the design.\u00a0 Control of the lights should be accessible while riding without safety issues.\u00a0 The lighting will need to be resilient to the elements.<\/li>\n<\/ul>\n<ul>\n<li>Imaging &#8211; There will be a 808-X camera used as an action camera embedded inside the helmet.\u00a0 The lens assembly will be extended from the camera housing by means of cabling.\u00a0 The lens assembly will also include a wide field lens.\u00a0 In addition, the camera microphone will be extended from the housing and positioned to allow clear recordings of the surroundings and the rider.\u00a0 Operation of the action camera should be accessible.\u00a0 Indication of camera operation should be clear.\u00a0 Access to the data storage will need to be provided.\u00a0 The entire imaging system will need to be protected from the elements.<\/li>\n<\/ul>\n<ul>\n<li>Controller &#8211; The <a href=\"https:\/\/www.sparkfun.com\/products\/11113\">Arduino Pro Mini<\/a> will be selected as the controller due to its small size and reliability.\u00a0 The controller will need to be protected from the elements.\u00a0 Accessibility to the programing port will need to be considered.\u00a0 This will allow system improvements through firmware updates.\u00a0 The controller should be programmed to use the least amount of power possible.<\/li>\n<\/ul>\n<ul>\n<li>Data Storage &#8211; Sensor data will be stored to a <a href=\"https:\/\/www.sparkfun.com\/products\/9530\">Sparkfun microSD OpenLog<\/a> breakout.\u00a0 This board was also selected due to its small size.\u00a0 The board will need to be protected from the elements.\u00a0 Removal and installation of the data should be easy.<\/li>\n<\/ul>\n<ul>\n<li>Power &#8211; I&#8217;ve used portable USB power packs in the past.\u00a0 This type of power source has been reliable in all weather conditions.\u00a0 The power pack used in the past was a 5V 2Ah 800mA source.\u00a0 This well suited to provide power to a 808-16 action camera for 5 hours.\u00a0 The power requirements for the sensor helmet will be more demanding.\u00a0 Unfortunately, the cells pose a fire risk.\u00a0 The new power system will need to be safe but also provide the same features and reliability as the previous pack.\u00a0 Specs for the power requirements will be dictated by load components.<\/li>\n<\/ul>\n<ul>\n<li>Sensors &#8211; This is the main purpose of the helmet, to detect telemetry.\u00a0 One of the key functions of the helmet will be to plot the data points using GPS information.\u00a0 This will allow data to be layered on maps for route analysis.\u00a0 The imaging system will record 1280p 30fps video.\u00a0 Data points can also be overlaid the video for realtime analysis.\u00a0 The sensor groups can be sub divided into these catagories; Spatial (GPS, 3-Axis Tilt, Compass), Meteorological (Temperature, Humidity, Light, Barometric Pressure), Environmental (Dust, Sound, CO1, CO2, Methane), and finally Biometric (Heart Rate).\u00a0 These sensors will need to use the least amount of power possible.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>I had posted earlier about the concepts behind smart helmets.\u00a0 I will expand on that with a fundamental design plan of a sensorhelmet.\u00a0 This project will start with a component list of the items that will comprise the sensor helmet.\u00a0 It breaks into 7 distinct category groups with sub components in most of those groups. &nbsp;
