The research studied on the development of the solar oven with automatic hybrid system for agricultural product processing. The oven was aimed to reduce problems by using regular in the normal solar oven which works only in daytime in order to use it anytime. The result found that the suitable direction for installing the solar oven was facing ; the north for the sunlight all day.
Main objective of this research was developping a remote controlled solar-powered watercraft together with a cost of production''s analysis which interested farmers could use to craft a suitable model for them using local materials. The watercraft''s control unit was microcontroller Arduino Uno R3 with radio frequency remote control. The watercraft was drived by DC moters.
This research presents the study and construction of solar aerators that can control motor speed by a wireless signal. The proposed machine used solar panels with 570 watts to generate electricity and collected electric energy with 130 AH battery capacity. The 250 watts DC motor was used to rotate the turbine which could be used with 6 or 8 propeller turbines.
