10 STEPS FROM PROJECT CONCEPTUALIZATION TO FINALIZATION
Practiced by Edgefx Kits and Solutions
- Choosing right technology & design
- Tentative circuit schematic
- Bread board assembly
- Re-designing the circuit
- Final testing & BOM
- PCB design & layout
- Final Prototype ready
The project is first conceptualized keeping in mind the real time implementation of both for Home and Industry.
Simplifying the complexity:
Increased complexity needs simplicity. This is kept in mind while considering fresh engineering students understanding level.
Choosing the technology and Design
Drawing tentative circuit schematic
A tentative circuit design is then made based on its ease of availability of components.
If the project involves microcontroller programming then our expert programmers are assigned with the task of writing the program preferably in C or embedded c or MPLAB or AVR studio etc as per the selected microcontroller.
The best way for design validation: The program is then invariably subjected to test and validation by appropriate simulation software.
Bread board assembly
Small projects are then assembled on a solder less bread board while for larger ones are tried on zero board duly soldered,
Larger circuits on Zero board are tried on zero board duly soldered.
Re-designing the circuit
During the testing of the prototype all the changes are recorded after getting the final output of the project as conceived.
Complete testing on general Purpose board (zero board)
Complete testing on general purpose board (zero board) is carried out before designing the PCB.
Final circuit frozen
• 330R 1
• 10K 1
• 1K 4
• 1K PRESET 1
• 470uF/35V 1
• 10uF/63V 2
• 1uF/63V 4
• 33pF Ceramic 2
• 7805 1
• AT89S52 1
• ADC0808 1
• ULN2003 1
• MAX232 1
• 40 PIN BASE 1
• 16 PIN BASE 2
• 28 PIN BASE 1
• 1N4007 4
The final circuit is then frozen with its bill of material as seen on the left.
Thereafter PCB design is taken up on the computer keeping in mind the layout that a student can easily assemble and understand the same. The PCB is then outsourced from vendors.
The Final Prototype
The final assembly takes place on the designed PCB and then is duly tested for desired out put. In case of any error the PCB design is corrected and the final project is then ready.
