The only design i made is twin led connect to battery. but that one also the led burn out because i put 9V battery.

Hmm.. wonder how many of you have personal computers with (printer) parallel port and (RS-232) serial port. The future will be without those while I am still relying on parallel port a lot. Programming microcontrollers and flashing Nokia 3310 firmware.

I'm now looking at Microchip's microcontroller with USB support. Thinking of playing with USB. Can anyone tell where to get USB connector? Perhaps I start by making a smart card reader that plugs into USB. Yeah, I'm also looking for smart card connector.

As what i know, many still now using parellel port coz using usb port must know how to create the driver..serial wor~~

here got some interesting things to share...spotted a robot site...quite interesting....check it out...

lol aiyak....u put there for long huh? and whats the purpose to put led there? torch light ?

aiks..usb smart card reader....pretty interesting its easy to get a smart card reader here..but usb type...havent seen any yet

Easy to get smart card reader? Can talk about it in more details? I want to know how much do I need to pay to get one. Not USB then what? Serial port, not available to some computers.

hi , ppl out there...I am trying to find an auto gate system to add on with my remote control. i try to find an auto gate system which can apply with this remote but couldn't find any..THis is my remote-control circuit website...Hope ppl out there can help me.

^^you can find some other brands like this in Jln Pasar but they are all made in China... choose wisely as they don't provide warranty sometimes normally around RM80-150, but depends on brand Some are over RM200 from what i saw last time

u mean u want an actual circuit for an auto gate that we use at home?

MORE circuit MORE robots please

Last time i built a remote control car controlled using computer through parallel port interfacing. I even interface it using normal gaming Steering, wheel and pedal too . I used VB to build its software. It was one of my college assignments.

As for USB interfacing, u can try acquire USB development kit. One of my friends built USB device application using 'Cypress USB development kit'. I don't know much about Microchip USB development kit, i only know how to use PIC 16F84 only . Can someone highlight it here


P/s: Right now i am in middle of developing a small autonomous robot as my part time hobby. Is there any robot freaks here ?

Resource for free components sample (read: FREE!!)

huhhuhu samples huh

cool man............your sharing would be appreciated

huhuhu samples...

Microchip - deliver using FedEx. good, but don't misuse it.
Analog Devices - not for Malaysia. But if you have an address in USA...
Maxim/Dallas Semiconductor - using normal mail. But I didn't receive my order a month ago.
National Semiconductor - no response. and I didn't bother to email them.
Fairchild Semiconductor - no response
Texas Instruments - using a courier service, comes in a box. Even give you expensive digital signal processors.
Cirrus Logic - didn't try
Linear Technologies - didn't try
Freescale (previously Motorola) -didn't try
ON Semiconductor - no response
Intel - I actually got samples of flash memory chips. But that is only available at that time.


Vishay - call my handphone and ask for purpose. No samples for non-commercial projects. (no money return no talk)

RTI Electronics - I got a few thermistors
Coilcraft - E-mailed to ask about student policy. Seems complicated - leceh
Cooper Electronic Technologies - only ordered printed catalog. and I received it.

i stumble upon this just now, might intrest some of you

omg! ^^ can build own R2 huh!

Anybody up for the job?

oowww not this again....my uni. is fond to this stuff...~_~ saw a lect. riding on it in front of Siti Hasmah few months back....
