Bill O'Donnell - Tech Gizmo Builder
These projects are advanced and not for a beginner student or newbie hobbyists. These pages are knowledgable and will help students and DIY enthusiasts understand more about Lasers, Precision Temperature Control and stepper motors among other things.
Auto Fill Circuit for Laser Cooling Loop - Ethernet Data Logging
Here is an automation solution with a ethernet usage. The code and diagrams are also there. This is something that covers many aspects of engineering in one project. Try such things out to learn, only after you have mastered the basics.
"The Ethernet connection is based on an XPORT form Lantronics. Basically it lets you use a serial port to send things over Ethernet. A PIC microcontroller with an A/D converter digitizes the pressure, the pressure set point, the high and low pressure alarm points and the supply voltage (since everything is ratio-metric). "

Talking Electronics - Colin Mitchell
The thrust of the course is for you to be able to design your own circuits and eventually move into the wonderful world of electronics as a career.
"There are many different types of power supplies, including batteries, plug packs, switch-mode supplies and a basic transformer and bridge"
The Power Supply - Basic Electronics
"However the simplest power supply consist of a transformer, one or more diodes and a large filter capacitor (electrolytic)."

Among others they also have Amplifier Design, Antenna and Filter Designer AF and RF and Basic Electronics Tutors.
Homebrew Projects - Laboratory of Changpuak
A Geiger–Müller tube consists of a tube filled with a low-pressure (~0.1 Atm) inert gas. (Helium, Neon, Argon,...). The GM-Tube has a coaxial shape, where the inner conductor (Anode) is biased with a high voltage (~500V) relative to the outer conductor (Cathode). The Tube has a window (left side) made of mica.
This GM-Counter is build on 2 PCB's. One is a standard high Voltage generating circuit, whilst the second is a Counter based on an ATMega16™ which also handles serial Communication with a host (Environmental Control).

This website conserves all those nifty little mini-projects (gadgets) which were developed to enhance the doctoral hats of our "fresh" doctors.
Doctoral hat electronics - After seeing this section i am convinced that the next innovation will be "SmartHat". There is ample space in a cap for an Advanced Android Multimedia Gadget with a Hepta Core ARM chip and all the works. Rush to the patent office !

Founded in 1974 by Federico Faggin, the inventor of the world's first microprocessor, ZiLOG builds semiconductor products that enable design engineers to break through the barriers to creativity and innovation in embedded design.
Zilog - Wikipedia
ZiLOG is the inventor of the award-winning Z80 and Z8 microchip architectures that have been embedded in over a billion end-use devices worldwide. Companies get more innovative products to market faster because ZiLOG products and design tools help them turn their imagination into consumer appliances, remote controls, vending machines, telecommunications controllers, home automation systems, spacecraft instrumentation, industrial automation systems, and thousands of other products.
Thomas Scherrer - Z80-Family
"This page contain docs, FAQs, source code, (cross-)assemblers, (cross-)compilers, utilities, etc. as well as links to other Z80 relevant stuff. Some of the info found here is property of Zilog, like hardware docs, instruction sets, and some of the software available."
WZMicro - Affordable Quality Electronics
Combine The Z-80 SBC and SB8466 interface card, you will have a full embedded controlled system, you can use it in any project you can think of, it is only limit to your imagination! .
The SB8010 is a highly versatile SBC comprised of a Z-80 microprocessor, 4 general purpose 28 pin sockets for byte-wide ROM and/or RAM chips, a Z-80 CTC counter-timer, and a serial I/O port (UART) using Intel's 8251. A bootstrap option is provided for loading an operating system into main memory using an on-board PROM.
On-board memory can be mapped in various ways to match the memory chips selected. The mapping options are accomplished using a PROM. The user may install his won PROM if a different mapping is desired. However, the six mappings provided should satisfy most users.

KTechLab - Open Source IDE
|From Design Gopher - Electronic Product Development|
Integrated Design Environment (IDE) for electronic and PIC microcontroller circuit design and simulation. Featuring an extensive circuit designer with autorouting and simulation of many common electronic components and logic elements, KTechLab is the idea tool for educational or hobbyist use. You can simulate analog circuits and logical circuits using KTechLab.
You can write programs using Assembly, C (SDCC), or Flow Code - program the microcontroller(PIC) using ﬂowchart. Another option is Microbe a programming language like BASIC.
KTechLab supports a wide range of Open Source PIC programmers, enabling ﬁnalised PIC programs to be quickly and easily transfered to a real PIC microcontroller.

Even now it is used after simulation or directly. Many RF and Power electronics designs may have to be verified and modified on Pilot Production. Digital Designs and Software/Firmware checks don't need hardware prototypes, but need a proven framework to test it on.
Hobby and Education learning must use breadboards alongside simulation, even though educational eda tools are used. Breadboard connects us with the reality, the way it is. Then you will even simulate better. Robotics and Developing Mechatronics Solutions may need prototyping and modifications many times over.
Soldering and Shiny joints are everything in electronics. One dry solder, a cut track, a solder bridge or splatter near the IC can make a card malfunction.
Thin copper tracks taking high currents, HV and LV circuit isolation, Ground loops, RF Antenna Effect, Ground Plane and Guard rings are just some things to know on Component to Component Connections, that make a huge difference.
In Design Notes of Soldermans Basic Electronics you will find my learning notes in electronics. How this learning happened ?
I had setup my Hobby Science/Electronics Lab when i was in School, In college i was helping others learn practical electronics. I worked in Product Design and Engineering Departments when i was Employed. During this time my Electronics Lab was a Free Training Center, sponsored by my own pay. Then i started my manufacturing firm.

Phoenix Science Experiments
Phoenix depends heavily on Python language. The data acquisition, analysis and writing simulation programs to teach science and computation.
Different sensors elements can be interfaced and accessed by few lines of Pythoncode. Phoenix utilizes the power of personal computers for experiment control, data acquisition and its mathematical analysis.
PMDK is an easy-to-use, low cost micro-controller development system. The hardware consists of an ATmega16MCU, LCD display and regulated DC supply. All the I/O pins of the MCU are available on sockets.
The instrument is designed using locally available low cost components and the design is freely available for commercial production. Design supports hardware plug-in modules for expansion. Phoenix is developed using Free Software tools.
The serial and USB versions can be easily interfaced to a PC. They can also be programmed through the serial/USB ports after uploading a bootloader program to ATmega16.

This site presents a completely novel concept in electronics education as an alternative to the classical approach. Based on human imagination and intuition rather than formal reasoning, it is implemented as an interactive multimedia electronics product.
It is intended for students, teachers, hobbyists, inventors and for all those who do not make do with traditional formal explanations of electronic circuit phenomena. The product consists of tutorials, collections of circuits, basic principles and heuristic tools implemented by means of dynamic text, interactive step-by-step controlled animations, hyperlinks, hidden explanation buttons and sounds associated to the circuit operation.
