  • The Soul of an Ancient Calculator
  • Hacker page     by Ken Yap
  • Around 1990 I picked up an old Sharp calculator from a flea market because it was only a couple of bucks and had 16 nixies. I believe it was this Sharp calculator model from 1969. I say I believe because at some point when I moved I threw away the case...

  • How Full Wave Rectification Works?
  • Hacker page     by Kate Baker
  • A rectifier is a type of electronic component that is used to convert alternating current (AC) to direct current (DC). It does this by allowing current to flow in only one direction, which is why it is called a rectifier. There are several different...

  • Super Servo for Everyone
  • Hacker page     by excuse1000
  • So, your robot needs a POWERFUL SERVO. It has to be robust, cheap, readily available with off the shelf items and no complicated software or unattainium. You need it to run on 12 volts and be easy to understand. So did I. This project solves much if...

  • Diode-capacitor RAM
  • Hacker page     by Ted Yapo
  • This isn't an original idea - I have found similar notions dating back to at least 1952! http://ed-thelen.org/comp-hist/SEAC&DYSEAC-5-150.pdf#page=11 Anyway, the idea is to make a DRAM memory cell with just a capacitor and two diodes. I played with one...

  • Different Types of Diodes
  • Hacker page     by kellygreene0805
  • Diodes are electrical components with two terminals and one-way current flow. The diode's ability to only allow the electric current to travel in one direction is well-known. When you need to rectify a waveform, you can use a diode in a radio detector...
