Where can I buy the other components?

James Newman

I don't yet own a propeller chip. I was looking into using one to design a circuit around, however. My problem is that if I decided to make more of these, maybe even market them, I know I can buy the propeller themselves right here. What about the other needed components for a propeller system? I have no problem getting the voltage regulators I'll need, or even the crystal, but I don't know about the EEPROM. What exact kind would I need? Better yet, where can I buy the one that comes with the kits here?

A list of components needed to run a pre-programmed propeller in a generic circuit, and where to buy them would be great. I may just be missing this somewhere on the site? I looked through the kits, and they all seem to have extras.

Thanks in advance,
James

I believe all the standard stuff you can get from Digikey or numerous other suppliers,
in quantities from 1 to 1000. Digikey is remarkably responsive even for the smallest
orders. If you can't find a specific part, I'm sure people in the forum would be happy
to help you look it up.

Mouser electronics is another good supplier. I find that they are cheaper on some things and that Digikey is cheaper on others, so I always check them both.

James, after looking into this myself, if you want to build something from this chip your best bet is to start with one of the protoboards. Let me tell you why.
The protoboard is low cost and already has all the connections/regulators including a dc connection simply waiting for you to plug a wall adapter in. It even has the header already connected so that you can connect a prop plug and start programming. Simply solder your other components to the board and go with it www.parallax.com/detail.asp?product_id=32212. All this for less than $25!
The fact is with everything going ROHS and Pb free, a through hole prototype board with contacts on one side will cost twenty bucks, I couldn't believe the prices for the most simple prototyping hardware on Mouser, it's disgusting. I figure they have to pay the Malaysians more to scrape the lead off [noparse];)[/noparse].
What I would recommend is that you purchase one of the resistor variety packs off of Mouser, so that you will have plenty to choose from when dividing up the voltage. This is where I'm starting anyway. I figure if I blow something I'll only be out a wopping 25 bucks.
