Vibration sensing gps tracker

Now upgraded to vibration sensing gps tracking system. The limitation of this version is the gps coordinates are not in google earth format. However, the vibration reporting is extremely useful as the tracker will first give your preset phone a remote call. If no response, it will then send you the new gps coordinate by sms.

This tracker system can also be internet server base but your need to purchase a gprs data sim card which cost > $298 hkd valid for 6 months. A local prepaid sim is only $98 valid for 6 months and no server charge cost. For anti-theft purpose, this is a good deal. For spying someone, gprs data will cost less sms.

NC700 Gas Consumption

23-26 km/L is a very realistic gas consumption calculated from real usage over past 6 months. Mostly as a commuter with 30% city and 70% highway. Average speed around 70 kph and I run mostly 80% in S mode. D mode has better fuel economy but no quite significant , I would say the gas efficiency in D mode (~2,500 rpm)  will be around 0.5 km/L more than in S mode (~3,000 rpm)

NC700 U6 LED Spot light

Each rated 0.6A x 12 V= 7.2W. Total 14.4W and LED is Cree U6 with 700 lumen. The reflector aims at far distance and the brightness is as much as the HID 50W in daylight.

NC700 Stock Battery

Made in Japan. Good quality !

Water temperature gauge

Finally installed a self powered temp gauge. Battery life good for a year. Range 0-120 deg cel. Sampling every 5 sec. Accuracy +/- 1 deg C. Gauge has waterproof done with silicon.

 

No hose cutting. Just CA a modified RC propeller (5mm shaft to hold the thermistor sensor) with bigger surface area. Using an infrared temp. gun and check the temperature difference is only 1 deg celcius from that of the radiator.

Quite satisfy with this. At around 90 deg cel., the radiator fan will switch on.

I was stupid to CA the sensor to the radiator water out side. I guess the radiator coolant in side is more appropriate. The tempeature on each side has a difference of ~10 deg cel.

Carbon fiber hugger

Very tough and light hugger. I love yhe carbon fiber pattern very much.

Dead Battery

 

 

So stupid that I forgot to switch off the alert indicator flash and run dry my battery. Luckily I installed a voltage indicator as that I notice the battery is low.

Connect to a 4s 2200mAh model lipo battery and carefully clamp the current which reads around 25A.

Immediately push start the engine and disconnect the lipo battery immeiately. Now the battery is charging up and reads 12.8V

 

P.S. An old 3s 12.6V lipo battery cannot start the engine. Though it can charge up the bike battery from 8V to 10.6V at 3-4A, which is slow but safer. Since I am in a hurry, I start up the bike with a 4s lipo (pre charged to 16.2V as emergency starteing battery) .
