Tables and Charts for Electronics

Tables, charts, quick reference cards, booklets and handbooks; are the most versatile tools of learning and putting the learning into applications. These should not have a lot of language or flowing text. These are - to the point, easy to remember, graphical, colorful (memory aid).

Just like a circuit diagram, flow chart or ladder logic can graphically interface with a human mind, Tables and Charts easily embed into ones memory.

Electronic Tables and Charts - delabs

Here are few sites which have learning material, It is easy to understand and refer these pages.

Electronics Concepts at HyperPhysics - Excellent reference for students learning Electronics.

Electronics Club - Tutorials and Explanation on most of the Basic Electronics to get you started.

Play-Hookey - Online Classroom - Interactive Resource, Electronics Edutainment.

Electronic Teaching Assistant - Interactive Learning of Circuit Concepts using Applets

Concepts are best designed, studied, maintained and understood in graphical representations.

Revealing the Ideas behind Circuits

Revealing the Ideas behind Circuits

Circuit Idea ? >> !

"Electronic circuitry is more art than science. Inventing novel electronic circuits is a result of human fantasy, imagination and enthusiasm. Fortunately, abstract electronic circuits are based on clear and simple ideas, which we may derive from our human routine. In order to really understand how circuits operate, we have first to reveal the basic ideas on which they are grounded..."

Optical Retro-Reflective Proximity Switch

This circuit is used to detect objects by reflected infrared light. It can be built into a cylindrical enclosure just like an inductive proximity switch. This is also useful as a level detector for colored liquids like oil. This has some immunity to ambient sunlight as it detects ac pulses.

• InfraRed Detector for Proximity Switch
• InfraRed LED Flasher for Optical Switch

This is a Hand Crafted PCB Artwork done by a PCB Vendor years back, this method may be used even today.

PCB Design -

• Solder Mask
• Partial Component Layout

This Layout may have many jumpers and may need to be cleared of Hairline shorts which has happened after i scanned it, cleaned it and enhanced it using image manipulation software.

This PCB would go into a 30mm Nickel Plated Brass threaded tube, with Epoxy or Teflon ends. These were turned components as quantities made were small. An Optical Proximity Sensor that would fit the same place as the eddy current or Inductive sensors, in existing machines. It could work a longer distance and could detect Non-Metals and even translucent fluids.

You can design your own PCB with CadSoft Eagle Layout Editor. Laser prints of output works well, but even Ink Jet printouts will work fine for small PCB's like this. Take 3x or 4x prints.
