Well first off before i get a 100 messages saying how much basic stamps suck to save you the time i know that ;)
ok here my question: theirs a really good tutorial on here (http://www.societyofrobots.com/member_tutorials/node/26 (http://www.societyofrobots.com/member_tutorials/node/26)) about how to build a parallax BS2sx microcontroller (normally $60.00) for $30.00 (or less now because some of the stuff cost less now) and it really seems like a good idea .. but the tutorial dates back to 2007 and the user has not logged on sense then and hence making the tutorial not outdated but full of dead links. the first problem i have is that the website he listed to buy the basic parts doesn't look reliable (www.jamco.com (http://www.jamco.com))....it just seems fishy. also as noted above the schematic link is dead and im not the best at electronics so i cant tell by the picture what goes where . my last problem is that the EEPROM name in the part list is different from the link he gave us.
Thanks to all in advance
-
First of all, that site is dead. Second, why do you want to build it exactly as a basic stamp is, why not customize it?
-
that explains it and what do you mean by customise it ??? If your wondering why im building it its because
. Fun
. Challenge
. i have only used basic stamps....... :D........Swicthin over to ardouino and C soon though 8)
. a cheaper option then buy n 60$ of premade unfun
. Fun

Hmm, if you are planning to switch to avr, why not take a look at the $50 robot board.
It only costs ~$15 to make and is more useful than the stamp.
-
Avr? you mean arduino ....... yea im a noob... also i have looked at that but i still wanna do stuff with stamps
-
The main chip in the arduino is an avr.
But if you are set on making a stamp, thats that.
What do you need help with?
-
Well first i know i could probably get the parts some where else but the 16K Bytes EEPROM and the link do not match up.... i think well http://www.parallax.com/StoreSearchResults/tabid/768/txtSearch/602-00013/List/0/SortField/4/ProductID/25/Default.aspx (http://www.parallax.com/StoreSearchResults/tabid/768/txtSearch/602-00013/List/0/SortField/4/ProductID/25/Default.aspx) thats the title but in the parts list it only says 16k bytes EEPROM
another thing is schematics..... not the best with electronics
-
That is the right chip, the tutorial must have an error.

oh ok i should buy that one
-
The novelty of making your own on a breadboard will wear out once you realize how horrible a microcontroller system on a breadboard is ;)
-
hmmm..... really well why is it so bad? also how is he programming it?
What is he using to connect to the CPU
-
There must be pins he plugs the programmer into.
Razor is right, breadboarded circuits are terrible. Once you've made it and tested it, move it to a proto board.
-
ok i will :)
btw what do you mean programmer i have the "Whats a Microcontroller" serial cord but does that count as a programmer and how do you hook it up btw sorry for the wave of questions

If it connects the microcontroller up the your pc it should work...
Sorry, im not too familiar with stamps :-\
-
thats fine and it does :)
ok one more leap before i start buying..... the schematic problem......
-
Whats the problem with it?
-
the links dead :(
-
wait nvm........gonna go buy stuff :)

lol, it took me a while to get what was wrong XD
-
yea me to :D gonna go buy stuff now thanks for the help

Here is a good link to Jameco:

At least it works for me.

thanks :)
