guys,i hv a sistem elektronik test on monday and i need better notes for me to understand(poli notes is still in malay although they already starting to migrate to english teaching)
i need more info on linear dc power supply process
can u guys help me by providing some links?

I haven't been there, but I think this is the location of Hondai Butterworth --> Wikimapia - Hondai Butterworth. The Hondai on Pg Island is correct.

There's tons of circuit on the net. Like this one --> MAX232 Serial level converter. And double check with the datasheet!

can i ask what sensor can link with parallel port? IR sensor can?

any sample?

What type of IR sensor? For what application?

i wanna do a thing like will sent signal to my pc via parallel port when something is block is between

ic.. Sensing between one IR transmitter transmitting and one IR receiver. Yup, parallel port should be able to do that.

any sample circuit?

Which circuit? The IR sensor or the communication with PC? Frankly, I have neither. it depends on which IR sensor, environment, controller.... Assuming fantasy1989 already had the circuit, I'm just stating the possibility of interfacing it with PC via parallel port.

found few circuit ..but not sure can use or not

can provide some sample diagram?

Which infrared sensor you plan to use? Mind to post the datasheet so I can have a look?

Here's the address for HONDAI.

hi guys,

where can i purchase electronics stuff online? had the link last time but lost it. Malaysian site that is.

What do you mean by Malaysian site?
The easiest and with widest choices for electronics components would be Farnell and RS online. Both has sales and support office in Malaysia.

bizchip?

Man, Farnell .......

I ordered my stuff nearly 10 days ago and it's still not here ... supposed to be 3-5 days according to their website. Gave them a call yesterday and they said it's still being processed =_=;;

Err you can check farnell online on the status of your order, including whether payment has been received, or item has been shipped, or still in transit from it's global warehouses.

So far my experience is those local stuffs will arrive within 5 days, UK stuffs will be next week if you ordered on Monday, and US will take 2 to 3 weeks.
RS is actually faster for local stuff, arrive in 3 days.
Note all these are business days.

And don't order those items that says 'please call'. Those can take up to 3 months to arrive.

Thanks for the advise.

Most of the components i ordered are from SG, a few from UK. And yes, been waiting for around 10 working days. (Mon-Fri + 2 Monday holidays)

I did check my status regularly and it's been tagged as "Received" ... However when i called them yesterday (and earlier today), the operator said that they have no record of my order confirmation. Forwarded the order confirmation back to them; gonna call them again later.

If status is "received", I think they haven't confirmed received your payment, and the working days don't start counting until they have payment confirmation.
To speed things up, I usually email my transaction ref # right after making payment.

Hurrrrrrrrr finally solved the problem.

Turns out it's their side and they gave me an invalid reference number. The best part ? Correct number is the next one. My order was never processed until i called them up again yesterday.

I had to cancel a few components as they will only arrive the day after my presentation =.=. Had to swap a RM5 IC for a RM20 one for the same reason too. ;_;

Anybody have experience with Arduino before?
