  • Summary on Electronic Timing Equipment

    Some time back I posted a request for info on electronic timing
    equipment. The response was quite fantastic. Many thanks to all
    who responded, and sorry that I have not replied individually to
    everyone. Each response was valuable, and this has resulted in
    me having great difficulty in making the final decision. The
    options range from constructing a cheap and simple "home-made"
    system right through to commercially available, yet expensive,
    systems which can download the data to computer. I have not
    included the prices of systems (none were given in original
    postings, only on follow-up).

    The original posting and replies follow:

    I have recently had all the same problems myself trying to find
    a timing system. Lafayette Instruments, Lafayette, USA (Fax 317
    4234111) used to sell a product called a performance pack
    (#63520) which I believe used infra-red sensors, a digital clock
    counter and tripods. When I was looking around December last
    year, this item was out of stick and discontinued but was
    supposedly up for review early this year. You may want to
    follow this up.

    I ended up getting an electrical engineer from one of the local
    polytechnics to make a system according to my requirements
    (which sound very similar to yours). If you want ideas on this I
    can expand later. The price he charged was similar to the
    commercial product.

    Hope this helps.

    You might want to contact the electronics technicians at
    Southern Cross University in News South Wales, Australia for
    such a system. They have put together a nice one in which you
    can have as many timing lights as you want and works well both
    indoors and outdoors. The technician name is Mark Fisher and
    have included two email addresses for you. The cost is about
    $1000 Australian dollars depending on the number of lights you
    want. Hope this is of some help.

    Best of luck.

    I had a look at a lot of different timing systems both in
    Australia and overseas. Most were very expensive, had limited
    battery life, subject to false triggering etc.. In the end our
    Technical Services Department did some R&D and came up with a
    system. It has dual beam lights, computer interface for
    downloading results, and the batteries run for days between
    recharges. It has worked very well for the biomechanics section
    and we do a lot of timing measurements. I believe they have
    just come up with a contact mat attachment which allows you to
    also do vertical jump tests.

    I hope I am not sounding like an advertisement. If you would
    like more information I could pass your email address onto the
    Technical Services Department of my university.

    There are a few commercially available systems available in
    Australia including one from Canberra (DDH) and another
    developed at the Australian Institute of Sport.

    If you need further details please email me directly and I will
    dig them up.

    Our laboratory technician here at the University of Canberra
    (Ben Sorensen) has developed a three beam infra-red timing
    system that is becoming fairly widely used throughout Australia
    (used at the Australian Institute of Sport). The costs work out
    at approximately AUST$1000 per gate. I have used this system
    extensively and have had no troubles with it.

    Ben can be contacted here at the University on 61 6 201 2308 or
    by Fax on 61 6 201 5403.

    I hope you have some luck in finding what you want.

    From: "Leigh F. Bacher"

    You may have already considered this... but if 'all' you need is
    to get the time between two points in space of a moving object,
    perhaps you could use burglar alarms (one at start and one at
    end?). The time that the beam was broken would seem to be a
    very accurate index of when the body reached the point of
    interest. I do not know how much they would cost, nor do I know
    how easy it is to access the pulse marking the beam break.
    Good luck,
    Leigh B.

    I have a suggestion with the timing problem. At my old
    institution we used a Dekan (sounds like Deacon) timer and some has been a long time since then and I was not
    totally involved with that protocol. I believe that the Dekan
    company has offices in Chicago, Illinois, USA.

    Good luck,

    For your first question you should try Power Systems, Inc.
    Their address is P.O. Box 12620, Knoxville, TN, 37912, USA.
    They have some timers with extra sensors which can be added.
    The price is $819 plus $329 for each extra sensor. Their phone
    numbers are 800 321-6975 and FAX 800 298-2057. Other numbers
    are 615 947-5229 and FAX 615 947-0319. Good luck

    I put together an inexpensive system for timing walking/running
    using slightly modified off-the-shelf components, purchased at
    Radio Shack (do you have Radio Shacks in Johannesburg?). It
    consists of two infrared photorelays (Cat. No. 49-551A - about
    $40 U.S. each) and a LCD stopwatch (Cat. No. 63-5013 - about $20
    U.S.). The stopwatch was modified to connect an external switch
    in parallel with the start/stop button, and a resistor was
    changed in the photorelays to reduce the reset time (otherwise,
    events lasting less than about 3 seconds could not be timed).
    The rest of the system is just wiring - anyone with a little
    electronics experience should be able to put it together quickly
    (it took me less than half a day to put together a nicely
    packaged system).

    The photorelays are designed for security/intruder detection,
    run off of a 12Vdc power supply or battery (draws about 60mA),
    and include a light source, photocell and relay circuitry in a
    small box (54x84x75mm, 350 grams). A separate reflector
    (included with the photorelay) must be placed 1 to 9 meters from
    the photorelay. The system timing should be accurate to 1/100
    second, but overall accuracy is limited because the photorelays
    are triggered by whichever body part happens to cross the beam
    first (errors are minimized by placing the beam at shoulder

    If you want more details on this system, let me know.

    What exactly are you trying to measure in your soccer
    experiment? I have measured soccer ball velocity in the past
    using a radar gun. It is easy to use and it works in both
    directions (whether you stand directly behind the subject, or
    directly in front). Let me know if the radar gun is an
    acceptable solution.

    Good Luck

    If you have a Radio Shack in your country there is available an
    Infrared Photorelay Sensor System for $40.00 that will allow you
    to make a timing device like you want. It will take several of
    these sensors along with a timer to build your system, but
    should not cost more than $250. The Radio Shack part number is

    In addition, a fax was sent from NEWTEST describing the
    POWERTIMER system which is capable of assessment of mechanical
    power in jumping (contact mat), speed testing (photocells),
    reaction time and throwing/kicking velocity etc. The system can
    store data for downloading to computer. Contact:
