Pull-Up & Pull-Down Resistors

Pull up and pull up resistors are two common terms that we could hear in the case of the electronics circuits.I have also tried to hear these concepts from  different people and will think at the moment that it has been well understood.Then when the next time I hear about it the concept would have long gone.So I was searching something that visually communicate it with least amount of  tech talk.And the following video from the Human Hard drive guy matched the profile.The guy has explained in a simple manner even to the depth that he actually explained what is meant by when we write 'Uc' which is a small and understood detail but an important point for a newbie.Thanks for the video and anyone looking into these concept could find this video helpful.


                     


Do remember the points :
  • Pull down resistor requires 10 times impedance of the internal resistance of the microcontroller.
  • Pull down resistors are also not inverting(Which as expected open means OFF and closed means ON).


Note to self : - Update this as more information and application is gathered about the pull up and pull down resistors.

My journey to understand business and evaluation of business - Part 2

      It is important to predict business outcomes for long term of at-least 10 years with good safety margin irrespective of market quotation for success in long term investment strategy.  For this business should have good earning potential in next 10 years. I prefer to follow this strategy as I am not a full time trader. List you circle of competence and go to step 1 only if its inside my circle of competence. Step 1 Predictable earnings - 10 yrs EPS to be found See if it has upward trajectory if there is any anomaly in any years - find the reason behind the anomaly. Step 2 Higher the price you pay lower the rate of return Find the initial rate of return: Price of the stock in current year(x) : Expected earning per share for current year(y) :                                                                  Price of stock in current Initial rate of return(z) :              ----------------------------------------                                                   Expected earning per

Buck converter Basics Notes for Designing and Implementation - PART 2 Simulation

Tried simulating with Qucs The simulation didn't come of well as I hoped.The Output is showing some kind of  waveform I have no idea of looking at how it became so. Simulated Circuit using IRF Z44 Mosfet (Now Vishay MOSFET Z44 )     Simulated Circuit using IRF Z44 MOSFET (Vishay) Waveform I got for Buck Converter Circuit     Now After trying the same in TINA spice simulator from Texas instruments I couldn't successfully produce an output.As I remember from the "Buck converter demystified" reference the ripple current will be maximum at the 0.5 duty ratio.So I have decided to redesign the parameter values for a different duty ratio of 0.25.   New parameters are;     Duty Ratio : 0.25   Period of Switching cycle (SW1) : 20us   Time for which SW1 is ON :0.25*20us = 5us   Ripple Current : 0.33*0.6 = 0.198A   Inductor : 454.54uH   Capacitor  at output (@ 100mv overshoot allowed ) : 262.581uF   In Qucs I made use of t

The case where I lost half my worth due to detour from my ideal path of buffet-munger way.

I always tried to learn from the very best in investment business Mr buffet and Munger. I have tried to understand and follow all their method while investing. Even though I tried to follow it I took a detour and it cost me half of my investment. Rules I broke : Always  invest long term. Always buy good business at fair price than fair business at wonderful price. Don't listen to guru's And I did break all the above rules. I happen to follow the modern warren buffet or Shameless clone of warren buffet as he himself advertises. Following where Mr Pabrai's idea of choosing stocks in a youtube video These where tips from him I followed to pick the stock 1.Business that Idiots can run 2. Great Management and Great Business is the way to go. 3. Low Risk - High uncertainty business that are always wrongly priced by markets - Look for stocks with PE less than 3 (More than 3 would be dead stocks or would not move much) - This was the point that killed me. 4. Bankruptcies etc. 5. Up
