wooo! Laser Mouse are slick! If you don’t know potential benefits of Laser mouse over optical, here is quick checklist:
– IR instead of Red visible light:
The Advantages are:
– Less power consumption: Since IR uses less power than LED, it is much more energy efficient while we consider wireless mouse. The difference is directly of the factor of 3x
– Better Resolution: Laser uses IR thats higher Wavelength and hence capable of detecting higher dots per inch (DPI). the attainable DPI with laser mouse are as high as 3500dpi which was max 2000 for optical mouse.
– Works on any surface: Having higher resolution, it has better capability of undertanding the glazy surfaces which dont work with optical mouse. I have tried it on mirror, glass, metals, plastic, cloth, skin, woofer and what not, it worked everywhere. 🙂
Being done putting light on Laser advantages, lets look at this mouse in particular.
The best part that will immediately grab your attention is its looks. Its shiny sexy red, with futuristic shape. Its small, smaller than regular mouses, I like small mice. If you don’t, it isn’t meant for you. Now, I’ve been using it since over a week, and im in love with this mouse. Great control, great resolution, average range of 10feet., and very handy sleek USB receiver. Infact its the smallest USB reciever and smmallest wireless LASER mouse int eh market.
Battery consumtion: The package or website doesn’t specify the power consumption. I took a risk by buying this little mouse. So after i have been using it heavily over a week, idecided to do some power measurement of this mouse. While going through the few available low power LASER mouse ICs, I found this one to be the best match for this device.
This is a low power chip has intelligent power managmenet system that takes care of preserving battery during idle time. It has idle consumption of 0.1mA and full usage consumption of 2.5mA.
But to calculate for overall mouse, we have to add the wireless 2.4Ghz consumption as well. So, I took my multimeter and here are the results:
Power consumed when:
1. idle : 1mA
2. light usage: 7mA
3. Fast/heavy usage: 10mA
That sounds pretty good. Being powered by single AAA battery, Not bad at all.
Assuming you have 700mAh re-chargeable battery, it will work for 100 hours of heavy usage.
Lets assume a typical usage: 1hour heavy usage, 1 hour light usage, 3 hours idle time/ day
battery would last = 35 days
Assuming you have Alkaline battery like Duracell 1250mAh
Battery would last = 62 days approx.
Good for a single AAA battery.
