DIY for Higher Functionality
The DIY Augmented Reality Laser Cutter is great for businesses that would like to brand and customize their products.
I have been thinking to utilize the Arduino to create a MPPT solar charge controller. As the market develops new sensors and charging algorithms, the Arduino would enable upgradability to existing hardware. And, if the sensors already exist but, its price is too high for its functionality for instance, digital specific gravity sensors have a higher price than an Arduino at the moment then, the user could wait for economics to push the price down of the sensors before including it into their environment.
