Vital Signs

Hi. we're making a project about vital signs. i just wanna ask where i can buy an LMC6064 or OPT101 and AD620 Differential Amplifier here in the Philippines. or what are the alternative components can i use for that? thanks :)

Why not just order from China like everyone else?

Not everyone else orders from China. I do not buy any chips or boards from e-bay. Too much trash out there.

I do a decent amount of my ordering from Digikey, Mouser, Newark myself. However, I hear time after time that people in other countries have a lot of trouble buying from them because of very excessive shipping fees. And somehow I doubt there is a good large inventory distributor like them in the Philippines. If I am wrong on that I would be interested in knowing who they are. If I were over in the Philippines I would use China more than I do now. If you are building one-off stuff for yourself, I don’t see any good reason not to. I haven’t gotten burned except on the easily identified fake MAX7219s and even those work unless you daisy chain them over about 10 ICs. In your situation, where you are building boards and selling them, I understand your reluctance.

I don’t feel so badly screwed on this order. All 4 displays work great and they got them to me in about 10 days:

is there any alternative components that i can buy in the Philippines???

I just don't know if there is going to be any significant Filipino expertise here. This board has an "International" section but just more major non-English languages are listed. They didn't make a sub-board for the Filipino. You would be more knowledgeable than we are are finding a message board in your country, directed at your countrymen, that has posters that know where the local outlets are, if there are any.

I hope I am wrong and someone knows. Is there a big interest in Arduino and hobby electronics in the Philippines? Should there be a sub board? Not that I can make that decision, I just want to hear your opinion.

Wow, what happened to the price of those little OLEDs? I had been buying them for $3-4 each as recently as 5 months ago. Is there a shortage?

That was the price for 4 of them.

They actually have spiked a bit with some of the Chinese sellers since I bought them but there is at least one seller who still has a very good price...

(this is a two-color screen which may not be what you want)

I got mine at $3.79 each. That seller raised it up to $12.88 as he was selling out and sold the last few for that much. Dumb buyers. Not me.

Apparently. It seems that everywhere price is doubled.

I'm guessing OP's already tried Tayda?

They're Thai. Does Thailand ship faster to the Philippines than Chinese sellers?

All of the sudden I am hungry. What gives? :)

Not sure, actually! But I've used them to ship a bunch of stuff up here to Canada, and the shipping times and costs are bearable. Decent quality too--my personal preference is to go to them before I start digging through eBay, to be honest.

I've bought from them too. Great experiences. But from what I am hearing this guy wants pointers to some local places, which may not happen.

I prefer an SPI interface.

The seller I bought the displays for under $4 is now charging $11. You know, that's still a decent price. And the shipping cost and ship time from China is quite reasonable (I don't know how US companies can compete with that). But it's funny how you get used to something. I paid $20 for my first OLED display from Adafruit and I was okay with that. Then I paid $4 and that became my new set point. So now $11 seems like a huge ripoff, even though it isn't.

The Adafruit displays are actually better in some respects.

I use U8glib and it can drive many different displays and will drive sh1106 based displays either in I2c or SPI. I doubt the code side is much different.
