- Enhanced series / parallel resistance & capacitance calculator
- Calculation of preferred capacitor values with a choice of series from E6 to E24
“I present, below, a collection of projects I have worked-on over the past few years. For over a decade, I had taught both embedded systems (microcontroller technology) and digital signal processing and practice what I preach….”

Nixie Thermostat – A heating and cooling thermostat employing technologies spanning fourty years from the unique Nixie tube display, circa 1960’s, to a PIC 18F microcontroller, circa 2006.
A High-Powered Power Backup Inverter – The working prototype of the 2 KVA inverter is complete. Fed from an array of lead-acid cells totalling 600 Ah (at 12 Volts), it easily drives real-world loads such as single-phase motors. The inverter has been tested and found to operate at an efficiency of between 71% and 82% driving a variety of both inductive and resistive loads
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.

MadLab – Inventive electronic kits
MadLab has been made possible through the generous sponsorship and support of the Edinburgh International Science Festival, Zot Engineering and Microchip.
A really useful tool for the budding electronics engineer – a digital frequency meter. New and improved version.
- input signal range from about 15Hz to 8MHz
- new feature – bypass switch for low-frequency TTL-level signals from 1Hz
- internal accuracy +/-1Hz
- 4 digits of displayed accuracy
- input conditioning amplifier sensitive to 50mV
MadLab presents an absolute beginner’s guide to electronics. Following this short course will lead you from basic ideas about electronics right up to an understanding of how the simple MadLab kits actually work.
hobby-electronics.info information site electronics hobby. For beginners or learners taking an electronics course! would be a fun way to start. Electronics Projects page has some projects with a PCB layout for easy building too.
Learn thru Hobby Electronics
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.”
