If you need advice on semiconductors I wouldn't mind providing them since I come from a semiconductor backgroud

Anything from the standard group IV semiconductor like silicon to III-V technology, just fire away

what chip to use for handling large amp motors? just asking.. lazy to googling around.. hehe

anyone using microchip's PIC??

OMG. I love this thread, since I am currently in my first year of E&E engineering.

currently got project (actually a year two project), where we have to create a circuit. my group will do the mosquito repeller (using ultrasonic). but we need to modify the circuit (in order to get good marks). still thinking about how to modify it. actully, none of my group members are good in modifying/designing circuit. neither do i. i bought breadboard etc to do some self-experimentation at home in future ( after i settle all the projects )

btw, did you guys know where can i get moon shaped LED and other wacky-wakcky shapes LED? been hunting for them a few weeks already.

if ya don't mind me asking, what does a PIC programmer do and what is it used for?

Erm, anyone there willing to tell me more bout PIC?  and, where can I find electronic stuff here in kL or Selangor?

I now searching 2 robot for my referance, line follower robot and wall detector robot, I want to buy from forumer here that got these 2 robot. Offer me your best price. The robot is mainly powered by PIC16F84.

I want:

1. complete line follower robot project + overlall PIC discription language, include the definition of the language process. + complete circuit diagram.

2. Wall follower robot, and complete set of language as above + circuit diagram.
This robot is complete project for ultrasound sensor or similiar, such that will avoid a wall if it near to it, so that it will follow the wall nicely without hit it.

PM me your best price. I take all COD at Lowyat Plaza.

Thank you everyone

Hehe got a noob question here.I wanted a steady 5V DC supply...so I dicided to use a LM7805 regultor.The problem is that the 7805 get to hot so quickly and the other thing I tried using the 9V batteries when I connected it to the 7805 input I get only around 2.3V at the output and the 9V batereis got around 8.41V.

Wah, after surfing those website, I still cant be on the stream meh.

Still need advice here, well, Im really new to this kind stuff.

Perhaps there will be a person who can instruct me all the way..geez..

Erm, If I wanna grab a piece of PIC, how much would it be?

hi guys just find this post today, not many local forum talk about electronics (this is the first local forum for me)

currently i bought electronic component from jln pasar area, but sometimes component not available. especially the exotic component. so often go back home with empty hand and less petrol in car tank.

just wondering, any local company sell their electronic component online. I cant seems to find any, RS and Farnell only provide online catalogs but you to go to their warehouse to purchased their product.

any ideas,?
