What is it All About?

Seafoid offers a wide variety of electronics-related calculation tasks, for example:

  • Getting resistor values from their color bands.
  • Calculating LED dropping resistors
  • Ohm’s Law
  • Series/Parallel Connections
  • Heat sink thermal resistance calculation
  • Inductances of air-cored coils
  • NE555 circuit calculation
  • Vacuum Tube Identification

Download latest version (3.1), Mac OS 10.5 and later
For Tiger users and all people who like it old-school: Here is the old version (1.3).

What’s New?

Seafoid 3 is now compatible with Snow Leopard! And it comes with tons of other new features:

  • Calculating circuits with the legendary NE555 (currently as an astable and monostable multivibrator)
  • Revamped heat sink calculation. Additionally to the old way (calculating the resulting chip temperature for a heat sink), Seafoid has a new option called “Calculate Appropriate Heat Sink” where you specify the maximum chip temperature and the app will tell you what thermal resistance the heat sink must have.
  • Seafoid 3.0 combines the clean look of Seafoid 1.x and the function of Seafoid 2.0, plus lots of improvements and new features.
  • Seafoid is now localizable! The beta release will come with English, German and Greek translations.
  • Lots of minor improvements like better input information and exception handling.
