Develonet Posted March 9, 2014 Report Share Posted March 9, 2014 I can pay you for your time on this project, just give me a quote.I need some help for a speed sensor project I am doing. My plan is to have a laser pointed at a sensor at "Point A" and another laser and sensor at "Point B". The objective is to start a clock mechanism when the beam is interrupted at "Point A", and then stop the clocking when the object passes through the laser at "Point B". I then need this device to calculate the speed (in mph) based on that time and display the number on a LED number display. The distance between "Point A" and "Point B" will be 1 inch. The max speed of the object passing through the lasers is about 150mph. I assumed there would be existing circuits I could buy online but I can not find anything so I am trying to build my own. I have limited electronics experience so if you have a solution, please sketch me a rough schematic and details about the chips a other elements I will need and a price quote for your time. THANKS!!!

Hero999 Posted March 9, 2014 Report Share Posted March 9, 2014 Why not use radar?http://www.ebay.com/itm/Bushnell-Velocity-Speed-Gun-Sports-Radar-Gun-101911-/390773879599?pt=LH_DefaultDomain_0&hash=item5afbf0332f Quote Link to comment Share on other sites More sharing options...

Hero999 Posted March 11, 2014 Report Share Posted March 11, 2014 Radar will not work in this project I am doing.Why not? Have you tested it?What is it you want to measure the speed of? Quote Link to comment Share on other sites More sharing options...
Develonet Posted March 12, 2014 Author Report Share Posted March 12, 2014 Nevermind...not looking for questions here on why not this or that. Was looking for help with building a circuit. I went and hired someone that could actually do it. Maybe I will post my schematic here when completed. Quote Link to comment Share on other sites More sharing options...
Hero999 Posted March 12, 2014 Report Share Posted March 12, 2014 You've been asked questions because you haven't provided enough information. No one will be able to do what you want regardless of how much money you pay them, unless you provide them with a detailed specification of what you want and are able to answer the appropriate questions.
