I need a timer to capture at least 20 / 30 events (millisecond accuracy, during a period of 20 seconds). The trigger (time = 0) could be a pair of bell wire. After that, each event should send a signal to the instrument (and the instrument records the time) using a bell wire. Currently I can get an instrument that can measure the time for one event - a pair of bell wire triggers the instrument and another pair of bell wires stops it. See attached document. the time for the events must be stored in the memory (SD card) and after the test, the data will be downloaded (txt file). I need a quick prototype to test ( and hence the budget of AU$250-750) it and after that (which will be another project), improvements will be required to have the version 1.0. I envisage a final instrument with dimensions around 15cm x 15 cm x 5 cm (however there is flexibility).

I have over 35 years experience as an electronic design engineer, please see my profile for more details. Because of my wealth of experience, I will be very pro-active in advising you best solutions to meet your requirements. The current price and timescales are only place holders to allow me to communicate with you I would prefer to work in milestones but cannot define these until I have more details Please can you send me further information as I am unclear. Will the device have just 1 input pair of wires or multiple inputs. If is just one then only an open or a close can be detected. Best Regards Dave Lelievre

Hello, Thanks for posting the project. I am an Electrical Engineer with 30 years’ experience of Customized Product Development for Instrumentation and Control applications. I am based in Kolkata (India) and running a business in the name of "Zetek Systems". I have a good hardware setup and a team for fabrication and testing. My solution will be based on AT89S52 micro-controller. The data will be stored in flash memory. The output can be give either through a serial port (which can be captured by a Terminal Program running in a PC/Laptop) or to a Pen Drive. For this project we can discuss deliverables and milestones through chat. Looking forward to your valued reply. Regards - Debasis Basu

Hi I am interested in your project. with today micro controller it is not difficult to accomplish this type of counter, it is important to know what will be the frequency of this count and they can happen at the same time, the signal will be coming from the same switch that start the sequence or we will have different switches also when we have a physical switch closing or open, we have have an unstable state between on or off that can last for around 20 us, equipment usually use denouncing code in the program or capacitors in the hardware to filter this but it is always good to know if the period of your signal will be at some point in the us scale
