Android GPS tracker

[capone01]

Hello,

I have created a GPS tracker using an old Android Phone. Now I want to connect to phone to the battery of my bike so it will stay 100% charged at all times.
My question is, howlong will my battery hold without riding? Will the phone drain my battery in 2 days beeing idle or will it be weeks?
I have a Kawa Z750.
Anyone has some tips regarding this?

Thanks

Someone will find the phone and remove it long before you know its stolen... but if you were using the battery > usb charging, wouldn't expect more than a day or 2, I've charged stuff on my R1 for around 8 hours and the battery voltage went from 13.1 to 12.2.

your tracker is garbage as once its in a garage or underground or in a shipping container it will most likely not work and can easily be blocked

either spend the money on an almax or protector chain or get a proper tracker from www.tracker.co.uk

Just mesured the phones usage... it's 0.015A, the battery is 8A/hour, this means I theoreticly have more then 14days of charging without draining the battery to 0.

I can assure you the cellphone GPS works just as good as a 'professional' overpriced tracker. And if I manage to hide it well enough, nobody will find it.

Where I live, stolen vehicles go to Poland, France, Eastern Europe coutnries, rarely overseas. This means it will probably be shipped in a Truck which will be easily located with a GPS cellphone.

Is it just a phone? Or did you take it out of it's casing and try hide it somewhere out of sight?

I would imagine the first thing these people do is look for a tracker or alarm connected to the battery and disconnect it, then it's a case of tracing the wire back to the phone and it's out and done with.

I'm sure Woo will be along to set you straight but the proper trackers don't just use GPS, they use another band VHF? as well which still works if the bike is in a garage or lock up which it most likely will be.
The phone thing is probably all right if it's chavs taking it for a joyride but with a professional thief it will be useless.

A lot will depend upon how often you are updating the position. Keeping the GPS active and a data connection live will chew through the battery quite quickly, whilst putting everything into sleep mode and only waking up if, for example, an activation SMS is received will keep the battery usage much lower. With a 1600mAH 16.8V LiPo pack I've kept a Samsung S3 and Garmin 705 alive for about ten days (using the Garmin for navigation, with backlight at night, a few SMSes and a few minutes talk per day on the S3).

If doing that, I'd be tempted to make sure that the charger circuit for the phone has a low voltage cut-out, so it will let the phone die rather than completely flatten your bike battery.

As an aside, does anyone use a good Android tracker app? Years ago I used to use Copilot Live on my Windows Mobile handset. That had a really good feature where you could enter someone's email address, and it would send them a link to a website where they could find your position (and, optionally, having been granted the right permissions, send you messages or add/change destinations to your itinerary). The really good part of that was that you could time-limit their access - so I could say to a friend that I'd be expecting to arrive in (say) four hours, but if they check that site they'll see how I'm doing without me having to call them, and without me giving them the ability to see where I am forevermore.

Copilot on Android doesn't seem to support that, and I've not found anything else that does.

dude when it comes to trackers you get what you pay for cheap ass shit like gps means you have a lol chance of getting ur bike back.

ive linked a proper tracker if you dont wanna do ur research on it good luck with ur gps tracker but the vhf tracker has worked as it got my mates R1 back real quick with 2 other bikes recovered as well.

overpriced good shit gives good results just my 2 cents and advice

all the best

Great idea. As a suggestion, how about a small, rechargeable, second battery?

I have a fairly cavernous underseat area and could easily fit a second, rechargeable battery, to be recharged from the ignition. This could then power the tracker unit when the engine is off without draining the main battery.

Don't know if your bike has enough space down below but this would work for me.

A-team logic I'm afraid.

great for films but in reality and in working situations using an android phone just isn't going to cut it for many reasons.

I'd save the time, effort and frustration by just getting a dedicated tracker.

BUT....All this is probably irrelevant as, looking at the OPS joining date and the date of the post....I fear this is indeed a troll thread. and most likely ITM with his 2nd account daft threads again.

Hi

Your calculation appears to be leaving about 1/3 of the battery capacity as spare (ie, full battery capacity at the current consumption you give is about 22 days worth). However 8ah seems quite a small battery for the Z750.

Plus point of the tracker you control yourself is that you can play around seeing the routes you have taken, etc.

All the best

Why not just combine one of these https://www.amazon.co.uk/gp/aw/d/B0012GMDC4/ref=aw_d_pd_electronics?qid=1388176797&sr=8-10 with one of these https://www.amazon.co.uk/gp/aw/d/B003XDQUQE/ref=mp_s_a_1_4?qid=1388177039&sr=8-4&pi=AC_SX110_SY165

More reliable than mucking around with old cell phones.

Quick question if bike/car theft is next to zero where you live then why bother with a tracker why not go for a heavy duty chain like some of the guys have already said and save the hassle of running your batter dead?

if my bike got nicked, I don't want it back thanks.
