How to run a CD ROM motor
Have you got any idea on how to run a CD ROM motor using a battery. I am trying to make a small Indoor Helicoptor and want to know how to design a ESC (electronic Speed Controller) to drive the CD ROM motor. Here is the datasheet of the IC on the board http://www.rohm.com/products/databook/motor/pdf/ba5983fm-e.pdf

Microcontrollers and its usage should be common knowledge in this 21st century. However, all books are written in English so average electronics guy in Sri Lanka finds it difficult to grasp the technology. If we think carefully, the majority of people who repairs and builds electronic systems are not graduates or diploma holders. They tend to be average do-it-yourselfer, learned most by poking. So it is very clear the knowledge of Microcontrollers, the next logical evolution of basic electronics, should be taken out of Universities and spread across the general public.
It is a shame that both education and supply of martial are both scares in local market, so this has much become a taught-subject even at university level, except Engineering faculties and few technical schools.
Simply put, 555 Timer IC became a huge hit, since of its versatility, so do 741 OP Amp. They were used in many different ways to achieve solutions for most common problems in circuit design while dropping component count onboard. In the same sense, a microcontroller can be used replacing many analog and logic components needed otherwise. PIC microcontrollers (by Microchip) has done the same revolution in 90ties where 555 revolutionized circuit design in 70ties. In another words, PIC made microcontroller based electronic design to reach the mass.
Open for questions and clarifications on the subject
If anybody wants PIC / ATMEL microcontrollers, SMD resistors and capacitors, I may help you out.
Kavee
I have problem about EPROMs, EPROM need special UV erasers and anyone know how can we build it / buy it from Sri Lanka ?
I'm looking several places but still I have bad luck.
machan use EEPROM's . now that EPROM technology is outdated and dead
a long before.
Machan can anybody provide me with a GOOD e book to learn PIC programming and circuit designing ???
Hey LANKAVEE ,Im looking for 16F628A, 16F88 and 16F877A.
Can u give me a quatation for 30pcs each.
Do u hv any SMD LEDs.
I also want ATmega8515 8MHz or AT90S8515 8MHz

Hi guys, I have seen some increased interest in embedded field in our country which is very good. About 6 years back when we start embedded, we didn't get much help from people. We didn't hear the word DSPs when we come to UK about 5 years back. However we are lucky enough to work with hi-tech devices like DSPs, FPGAs today. We made a forum to share our knowledge and experience for talented people who are lacking resources. The forum is ExpertCore.ORG (as stated in my ElaKiri account).
We particularly discuss about embedded and mechatronics including microcontrollers at ExpertCore.ORG. Three of us who were graduated from SL universities and working in the field of electronic manufacturing run this site for the benefit of people like you. Though we work with DSPs and FPGAs mostly at job we use microcontrollers from Ti (MSP430), Atmel (Mega128) and Microchip (16/18F877) for small purpose automation work.
In addition to embedded, we have some other interesting sections. (We also need people to work with us who have a passion in knowledge sharing)
One thing to remember. ExpertCore is 100% technology related unlike ElaKiri which is catering for almost all communities.
If you guys have questions or practical problems, we can share our experience depending on the free time we have. You can ask in Sinhala as well. (Note that we do not sell anything, just knowledge sharing).

Try the latest Sri Lankan robotics/electronics website, http://robotonomous.com/forum . Post it in the forum. You may get help asap.
Ai assembly use karanne. C walin gahuwanan peli dekai ne
Goto: The Sri Lankan Robotics/electronics website http://robotonomous.com/forum
SMD caps and resistors are already available in sri lanka. You can find most of them in pettah 2nd cross street or, goto KVG electronics ratmalana.
