Alexander was very understanding and helpful in guiding us in the right direction and was able to answer all the questions we had for him. I would highly recommend Alexander to anyone looking for expertise in circuit design.”

  • Bild von brotherofninth Answering couple questions about wireless communication $150.00 USD

    “His communication skill is ok, but his work is completely horrible, the answers he provides are off topic and 100% copy and paste. He just google the keywords and paste something to it. He didnt even look at the questions and think of the answers. Instead of providing correct answer, what I got is random things. Even as a person who dont konw the correct answer, I can still figure out what he provided is wrong. Dont hire this guy. He is a scam.”

CO2 GTAW/MIG/MAG welding machine development

Sep 2011 - Feb 2012 (5 months)

The 220V/380V ac input is rectified to get high voltage DC source for feeding welder sufficient power. This DC high voltage will be step down to 20~40V DC output which is the range of voltage used in MIG welding.

CVCF Device development

Oct 2005 - Apr 2006 (6 months)

The input voltage range is 110~230V and the input frequency range is 30~55Hz. The output is stayed in constant voltage 220V and the frequency is remained as 50Hz. The modern inverter technology is used in CVCF.
