Hello All, I have finished developing a motorcycle alarm (actually, it's a 2nd iteration). Here is a link for those that are interested-- http://jsno.leal.com.au/proj_micro/trikit.html The features of this system are-- - 3 sensors (X & Y motion sensor, battery voltage monitoring) - 120dB alarm - system talks to a mobile phone when triggered, and gets it to ring a preconfigured number. - 1700mAh rechargable system, running low voltage logic giving a theoretical 6 day uptime (without being recharged). I am currently soak testing this design. I intend on making some units to sell. If I am happy with the design, then I'll make these units for other people. cheers
Looks interesting Jason. The main unit will definitely need to be a lot smaller to be saleable, but a quarter of the pictured size wouldn't be so bad - question though - are you restricted to just the 51/61xx phones ? While they are certainly cheap, they're a fairly large handset. Space is at a premium under the seat of most bikes (particularly sportsbikes), considering there's a whole heap of very cheap newer handsets from Nokia available which are considerably smaller - are they like to be able to be utilised ? Something like Nokia 1110 or 2112 for example. JL
Speaking from the point of view of an E&E engineer, there are a couple of companies that make GSM modules that are dead easy to interface. Instead of that big phone hanging out, you could fit it in the box with all the other electronics. Spark Fun sells such a module. <http://www.sparkfun.com/commerce/categories.php?cPath=66_68> its not as cheap as say a Nokia 5110, but it will make things much smaller. The GM862 they sell there can even have a camera, so if you want you could prolly make it take some happy snaps of the theif/ves as well. GPS tracking is easy. Get a serial GPS module, read coords and sms with GSM module. Just slightly off topic, but if you want to get really tricky and want faster and more continuous tracking one could possible use the 3G IP features of the new 3G networks and continuously stream locations to a central server over the internet. Only problem with this is that I've yet to find a 3G module with serial. I've really only seen this done with a mini itx board and a external handset. Skywings.
Hi JL It will . All concept designs start off being boxy hehe -- http://www.apple-history.com/gallery.html At the moment yes. Although, many other nokia phones could be compatable with this protocol. Yes, I agree. I will be getting rid of my gixxer next month. i doubt most bikes have as much boot space as the old 01 gixxer . I remember the dealer saying -- "..and you can fit exactly 4 UDL's in the boot..") (BIG SELLING POINT) I'm still to investigate other phones. If somebody had a phone they wanted support (something I could not get and was unwilling to buy myself), and were happy for me to borrow it for a while, then I would certainly try my best. Nb/ This project isn't a "New Inventors" style conquest of the world. Depending on demand and word of mouth, I will probably only end up making less an 10 units, and sell them to (most likely) people I know here in Adelaide. My aim is to cover my costs. If I do that, then I'll be happy with making units for people. My main drive though is to design something that is interesting to develop, something that isn't out there already and something that is very useful. If others find it useful, then I'll be more than happy to make one for them . Anyway.. Thanks for the feedback
Hi Skywings, Cheers. Thanks for the info . It is definately something to keep in mind. This is a cute feature. It is one that has been suggested by many people. However, my opinion is that to make this feature usual, it would have to be seperate from the alarm and hidden in another location of the bike. There are already GPS trackers commercially available. I would be reinventing the wheel if I designed a GPS tracker (and I could not approach the cost savings, size, and finish to that of a big commerical companies product). Cheers
and without it you're still reinventing a wheel that's already been reinvented a hundred times before... Nev.. '04 CBR1100XX
