Why this Blog?

The purpose of creation of this new blog was to add all my work that will solely related to my DIY Solar and wind electricity generation system. I will also add here the adventure of my DIY micro-hydro turbine (PAT) unit that has been planned to be implemented in the beautiful Kalam valley. In the recent past i unintentionally got attraction toward the green energy and studied a lot about.

My last visit to Karachi home was the turning point to divert all my intentions and resources toward getting into hybrid solar+wind electricity system. The 12 hours shedding at Karachi was really a mental shock to me. The 2Hours alternate load shedding scheme was so pathetic that for three nights i had only 6 hours of sleep in total. The Starting/Stopping the generator (located at the third floor) was a real muscular exercise especially the last part of the night.

The ready made solution requires a handsome amount of money. Here i will post my DIY approach to get the job done considering the advantage of being low cost, worth of experience and as per my requirement and quality. I intend to work on both Solar and wind turbine simultaneously so that to give the relief to my family.

Lets see will i have success in this endeavor?

CNC Mold Machining for magnetic plates Resin Casting

Today i CNC machined the molds out of 12mm thick MDF for resin casting of magnetic plates.The tool used was 8mm end mill at 70inch/minute using 3mm per pass depth of cut. The mold machining took 35minutes on the CNC router. The cast resin will help bounding the magnet with the CS plates so that the magnets stay at high RPM.


 Hole drilling started on my home made CNC machine.

 and the rest of the pictures are below.
and the magnetic plate fitted exactly in the MDF mold as desired.

Wind Mill Fabrication Started

I have been collecting components  for few years for  fabrication of  1KW horizontal axis wind turbine diameter 12 foot. Last year i purchased 24 Magnets Rs.500Ea, a Car wheel hub for making the axial flux generator for the turbine.

Recently did some activities for making this wind turbine functional till the end of September 2012. Structure being fabricated in local market. I have made the CAD model of Wind turbine blades using NACA 2412 profile.

Here is the Magnetic plates of the Axial flux wind turbine.




Here is the average wind speed data and other parameters for Karachi.

More advanced and Compact All New Sun Tracker


After loosing all the data from crashed hard drive, I started drawing the electronic circuit from scratch.This is all new sun tracker with multiple features. LCD Menu driven and more advanced and compact as compared to previous one.




Some complex programming yet to be carried out:)
