Discover Electronics Kit contains everything you need to learn the basics of electronics and make your own projects. It contains the most common electronics components as well as a prototyping breadboard for you to get started right away. Easy full color diagrams teach you how to bring your own ideas to life.
Systematic and Meticulous work has its own Rewards. An Engineers Notebook or a Hobby Experiments Log Book can go a long way in making a Cauliflower out of every Cabbage. (The credits of the Vegetable Analogy goes to Mark Twain)
1. Keep Work Place Clean.
Clean Tables and shelves every day before closing office, Put Cut leads and Solder shots in a separate cup to be accumulated and disposed later as these are toxic. In this cup other irritants like staple pins can be added and these can be clubbed in a month and disposed off as one metallic bulk for recycling. Never bring coffee or food to work area, Keep a waste paper basket on your side.
2. Work carefully to avoid injury
When cutting leads hold the lead in the hand and cut or it will fly all over the place. A piece like that may land on another equipment and cause shorts or it may go right into your eyes and cause blindness. Lead and Iso propyl alcohol and other Chemicals may be dangerous for health if handled carelessly. Do not use fingers, and teeth as tools it is bound to cause a injury to repent a lifetime. Be extra careful with 230V AC and more so with 440V 1 tr 2mA thru your heart and a weak streak of luck may be the last experience you ever had. Do not press your Luck too hard.
3. Protect Desk or table surface.
If you are cutting something let it not leave marks on table, even adhesive stains should not deface table, use a asbestos, Bakelite, fiberglass, hardboard surface which can be disposed once in a way. Before working put two layers of news paper on the table this prevents table from getting spoilt while soldering and newspapers being hygroscopic (water absorbent) they provide a natural antistatic surface to protect CMOS Ics and are nonconductors for any Live PCB kept on the paper.
4. Use tools and equipment’s in a gentle manner.
When you use weller Iron use it as a heat transfer tool never use it for prying or crimping leads or just pressing use pliers or other tools for that.
5. Document what you do and vice versa.
Have a register in which you can make records of what you did to solve a problem or what you learnt while making an equipment this information is valuable for the company to develop production methods and also useful to your team to solve a similar problem. Share abilities and skills with fellow employees but don’t share your company’s technology and database with any other company. When you leave a company use only the abilities and skills in that broad area to evolve as a professional.
delabs notes – 80s and 90s
These books Electricity and Magnetism, Optics and The Modern Revolution in Physics are very useful for any student of electronics. To have sound science foundation, Physics and Chemistry are very important for an Electrical/Electronics Student.
Biology and Environment learning is important for the Analytical and Medical Equipment designer. Chemistry is important for the study of materials which enable us to make new components and semiconductors. Maths cannot be ignored, it needs no special mention. Numbers are everywhere, this is the most important part of science.

Dual Polarity Power Supply
Two versions of a dual polarity power supply with printed circuit board artwork. The supplies are built around the popular LM317 & 337 complementary voltage regulators which offer very high ripple rejection as well as short-circuit and thermal protection.

An interesting website with many photos of electronic projects. There are not many projects but the description and photos and documentation are very useful for learning the art of circuit design.
Build it or go for a kit, this is a nice design for a Table or Desktop lamp. You will need to fix in a Enclosure with a Diffused Plastic or Glass Filter Front.
18 LED dimmable LED lamp
This circuit is a dimmable white LED lamp array with 18 LEDs. The lamp brightness is regulated as long as the input voltage is above 10.5V. A low-dropout analog voltage regulator is used for a simple and relatively efficient design. The lamp produces enough light to use as a a reading lamp or a small work lamp. – G. Forrest Cook
The 12V DC input voltage is routed through the 1A fuse and the on/off switch. The 1N4001 diode acts as a crowbar device. If reverse polarity is applied, the fuse will blow and the rest of the circuitry will be protected. Power is sent to the LM2941CT voltage regulator IC.

The true Christmas Spirit is in giving, You can only give if you have something, right. You can Have when you Acquire Skills, Imagination and a Cheerful Attitude.This will help you Create Things! – dapj
Develop a Skill this Christmas, Build these small LED Trees and give it to people who need a little bit of cheering up.
Christmas Tree – CircuitStew “This was the first and last complete prototype that I made on proto board. This style of prototyping produces circuits that are very difficult to understand, debug, and modify. Because of all the extra work involved they also take forever to assemble. Suddenly I became very interested in designing and fabricating custom pcbs….”
The name CircuitStew refers both to the jumble of electronics presented here and to circuit boards suspended in neon green copper etching solution. – Derek Wolfe
“This Christmas, Make and Give to someone that needs it most. That is the real spirit.” – dapj
micro-readerboard Christmas tree ornament displays a short message, one letter at a time, on a bright single-character alphanumeric LED display. In the animation here, the ornament is displaying the word ornament.”
Each ornament is pre-programmed with a list of 36 different short phrases. Every time that an ornament is switched off and back on, it picks a new message from its memory to repeat.
