Ian Purdie VK2TIP's Electronics Tutorials
Electronic Basics
Radio
Terminology - learn the basics, learn what's what! get a basic
understanding of all the major terms used in ham radio and electronics
Basic
Electronic Units - learn the basics of those important components
Inductance, Capacitance and Resistance
Radio
Basics - learn the basics at the necessary level to follow the later
advanced topics. Begin to understand LC, reactance, impedance, even Q and
other important basic concepts. Includes a great Javascript LC calculator
written to work out L or C from resonant frequency!
Resistor
color code - yes the much sought after color code chart.
Active Antennas
Active
Receiving Antennas - a discussion on some of the principles and
justifications behind the design of active receiving antennas for radio
projects.
Antennas
Antennas,
some rules of thumb for beginners - Every now and then somebody asks for
antenna suggestions. Quite often these people asking about antennas are
beginners who are afraid of making the wrong choice - a contibution on
antennas by James R. Duffey KK6MC/5.
Amplifier Design
Amplifier design -
Part 1 - learn how to design both a.c. amplifiers and r.f. amplifiers
Amplifier
design - Part 2 - amplifiers using emitter degeneration
Amplifier
design - Part 3 - amplifiers using emitter degeneration AND feedback
Buffer
Amplifier design - to buffer low level stages before succeeding
amplification
Small
Signal Amplifier design - to follow the buffered low level stages before
power amplification
Baluns and Mixers
Balun design - an
electronic tutorial discussing baluns
Double Balanced
Mixer design - an electronic tutorial on double balanced mixers
Filter Design
L.C. Filter
design - a comprehensive electronic tutorial for everybody into ham
radio or the electronic hobbyist
High pass
LC filter design - learn how to design high pass LC filters - Part 1
Low
pass filter design - the basis of many other filters
Band pass
filters for many purposes
Multi-pole
narrow band pass filters
I.F.
Amplifier filters as designed in the olden days
Oscillators
Design of RF
Oscillators - a discussion on some of the principles and justifications
behind the RF design and construction of radio frequency oscillators
Design
of Voltage Controlled Oscillators - a discussion on some of the
principles and justifications behind the design of voltage controlled
oscillators or VCO's.
Design
of Crystal Oscillators - a discussion on some of the principles behind
the design of crystal oscillators or VXCO's.
Power Supplies
Power Supply - 1
- a tutorial on the basics of designing simple power supplies for radio
projects.
Power Supply - 2
- regulation of power supply voltages.
Power Supply - 3
- designing with solid state regulators as well as using higher current
regulators.
Power Supply - 4
- a bench variable voltage power supply project for you to construct at
home.
Receiver Basics
Radio
Receivers - the fundamentals of radio receivers
A.M. Radio design
- the basics of a.m. radio design Part 1
A.M. Radio
design - the basics of a.m. radio design Part 2
F.M.
Radio design - the basics of f.m radio design Part 1
F.M.
Radio design - the basics of f.m radio design Part 2
A basic old time
crystal radio set - basic crystal radio set but includes a lot of design
information
a reflex radio
receiver circuit - out of fashion now but here are the principles,
design information and schematics
Radio Projects
Radio
Telescope - In response to some considerable interest I have posted a
project for you to construct a 30 Mhz radio telescope.
Passive
Antenna Re-radiators - Again in response to some considerable interest I
have posted some project ideas for receiving difficulties for you to
construct passive antenna re-radiators or "sort" of Q multipliers.
Test Equipment
LC Meter
Project and Kit - Now you can easily build a quality inductance and
capacitance meter (LC meter project). Ideal for any serious constructor -
designed by Neil Hecht of AADE.
Square
Wave Signal Generator - Build a basic first class electronic hobbyist
test instrument - ideal for trouble shooting. Includes a how to use guide.
Excellent beginner project to start your collection of
amateur-radio-equipment.
