Solar Powered Lawn Mower Cuts the Grass So You Don’t Have To

MowerFea2

It takes a lot of power and energy to keep grass levels down to an appropriate level; especially when it’s hot out. If cool glasses of lemonade aren’t around, the task at hand may not be completed any time soon causing the unkempt blades of green (or yellow) vegetation outside to continue their path of growth towards the sun.

Instead of braving the oven-like temperatures which will inevitably drench the person in sweat, this solar powered robot has been created ready to take on the job. With the heart of an Arduino, this device shaves down the grass on a regular basis, rather than only chopping down the material when it gets too long. This helps to save electricity since the mower is only dealing with young and soft plants whose heads are easily lopped off without much effort.

Internally, the robot’s circuitry interfaces with an underground wiring system that defines the cutting zones within the lawn, and proves to be a simple, accurate, and reliable approach to directing the robot where to go. If the device travels under a shaded area, a battery kicks in supplying energy to the engine. When sunlight is available, that same battery accumulates the electricity, storing it for later.

i2c for the fonera


La Fonera’s are getting pretty popular lately. [Lefinnois] hacked his to get i2c working. He used a 75LS05 to adapt the io levels, and some bit banging in the software to pull it off. Now the Fonera can be used for inexpensive remote monitoring via inexpensive i2c devices. Not to mention that this could provide a cheap network interface for various micro-controller projects. (I’m thinking networked thermostat for my new house.)
