I request your expertise for an interesting Hardware / Software project which could be scalable in a near future. I need 1 expert to set-up a prototype for internet connected speedometer and powermeter.
It supposes to build necessary hardware with all relevent sensors to get all variables I am looking for: Watt, speed, distance, RPM.
This device could be made of several parts, must be small enough to be fixed to crankset and handlebar. This device must communicated via Wifi to a server to aggregate data.
There are several others requirement which could make this project interesting for you like mobile app dev.
Hope to find an expert with whom I can discuss in details about this project
Micro-controlled cycling speedometer / powermeter (IoT)
1. Functional requirement:
Convert traditional indoor cycling fitness bikes into smart bikes to provide end-users with a new performance and sport experience. Vast majority of bikes used in these fitness classes are purely mechanical bikes missing embedded basic performance measurement and display.
It is expected to provide a cost-effective device easily configurable and mountable on indoor bikes which could measure speed, average speed (km/h), distance (km), rounds per minute (RPM), power and average power (watts).
It is expected to get a device which is user-dependent.
o a QR code must be attributed to each bike. User must sign-in with a dedicated mobile application, where he could have registered beforehand all necessary information potentially needed for measurements (weight, height, age,…).
o Following identification, bikes start transmitting parameters to server for performance measurement calculation.
o Smartphone used for identification should display user’s performance information in live.
o It’s not expected for the moment to work on UI.
It is expected to get 2 modes of use: individual and collective.
o When collective mode activated (fitness class), all devices (bikes) should be connected under same independent session. All bikes are in the same room.
o All data are transmitted to server for individual and collective performance display on the smartphone.
o Ultimately, we would expect different display on the smartphone (individual) and collective via overhead projection (performance comparison between users, ranking,…)
Second step of development, once hardware and performance indicators are properly aggregated, stored and displayed, it must be considered that application should display historical data and historical comparisons between users of a same collective session.
For your information, bike which should be used for the prototype would be like : http://www.nutri-cycles.com/documents/Image/seances-spinning-3.jpg
Please let me know feasibility and a rough estimate. Of course, if we decide to work together we'll work on an iterative way. I am not expecting a final prototype just based on one conversation. We'll be able to set-up skype meeting and even be able to travel
