Tom Jennings – World Power Systems

“I make things, mostly technological, but don’t hold me to that, consistency is not a human virtue. Electronics and software, cast iron and plastics, microcontrollers in vintage automobiles, faux historical machinery that could (not) have been; finely crafted, rigorously rugged, reliable, most often.”

The Model 01a (aka M01a) is a 3″ x 5.5″ self-contained controller board designed for embedded applications. It’s based around Microchip Inc’s in-circuit-programmable 14-bit PICs, and contains I/O expansion, a power supply and various goodies that I found useful in five years of using my previous controller board design.

The M01 board contains enough support hardware to pull off a lot of functionality. Before I get to handling common interface problems here’s a function-by-function description of the hardware. There’s some subtlety to some of the design that’s worth paying attention to.

Electronics 2000 – Calculators

A beginners guide to project building, technical data, interactive formulae calculators, software downloads including Electronics Assistant and EPE Index.

Electronics Assistant

Electronics Assistant is a Windows program that performs electronics-related calculations. It includes a resistor colour code calculator, resistance, capacitance and power calculations and more.

  • New 555 timer, voltage regulator & RC filter calculators
  • Enhanced series / parallel resistance & capacitance calculator
  • Calculation of preferred capacitor values with a choice of series from E6 to E24

The Course – “We start with a few lessons about voltage, current en resistance. Next, we’ll discuss power dissipation and capacitors, diodes and transistors. We now have enough knowlegdge to build a simple power supply. And after a few lessons about differential amplifiers and operational amplifiers, we are even able to design and build a professional lab power supply.”

MiscEl – Many Electronic Calculations

A swiss army knife for the Electronic enthusiast. This single program packs many applets that help you overcome the Formula Amnesia and even Poor Math Skills.

MiscEl – Many Electronic Calculations

The program contains a lot of pages with different electronic calculations. Each page contain one or more different calculations.

MiscEl - Many Electronic Calculations

Science calculators are on Geometry and Periodic table. Some Electronic Calculators are shown below

  • TinyCalc Can do the same as the entry line in Calculator, but is very small when pulled out.
  • Ohms law Ohms law, impedance of capacitor and inductors, complex power
  • Waveforms Calculates RMS, mean, PEEK, DC, FFT for different waveforms.
  • Thermo sensors Calculates for PT100, NTC and all types of thermocouples
  • Series/parallel Calculate/design series/parallel connection of resistors, capacitors and inductors

Periodic Table and other Calculators

Periodic Table and other Calculators

Periodic table of the elements contains the basic data about the elements in five languages.

EniG. Chemistry Assistant 2.4 An expression calculator for fast calculation of molecular weight of compounds by simple entry of chemical formula (the element symbols can be written in lowercase letters). The calculator also provides a list of common physical constants and performs various conversions between English and metric units.

Scientific calculator Sci.Calc is a fully-functioning JavaScript calculator that contain of practically any common and many advanced calculator functions (cosine, sine, tangent, power, square root, exponents, etc.).


Learning Electronics by Hobby DIY is not Complete without a sound Knowledge of Materials, A Periodic table Reference will help in Understanding the Metals and Semiconductors.

Every Metal has a potential for a New Component Discovery, Even a Breakthrough in SuperConductivity at Room Temperature will change the way we build Gadgets !
