Title: ordering parts! admin HELP PLEASE
Post by: knightimer on August 09, 2007, 05:54:49 AM
this is a question about digikey actaully, im from AUSTRALIA, sydney! and i wanted to ask you wat other sources i can get my parts from for yur $50 robot, cuz i cant seem to get them off there. any suggestions? also, the 5v linear regulator has so many different types...which ones? and the rest aswell, they have different types. help? the parts you listed arent specific. sorry but can you tell me wat they are exactly? (The $50 robot parts list ) and is it possible to program in visual basic? cuz i can use it quit well, but not for robots i guess. (.hex?) help. oh and $50 in usa is equivalent to alot in australia. ALOT. (curency rates, etc)

You can use visual basic for other robots, and with different hardware.  More specifically, as I understand it, you're not going to be able to put visual basic code on a microcontroller.  If, however, you use your computer as the brain, then you can do this through a serial connection. (and wirelessly with a bluetooth serial connection)

If this sort of project is going to benefit you in any real way, you'll probably want to learn for yourself about various types of electrical hardware.

Here's a link that might help you better understand the different types of components, such as the 5v linear regulator.

(note, I don't know how useful that link actually is, haven't had time to read it myself, but a good friend recommended it)

Can't help you on the other stuff...

For all your robot parts needs:
http://www.societyofrobots.com/robot_parts_list.shtml

Try mouser.com, they are much cheaper and more honest with shipping than Digikey.com

(and no need to write 'admin' in your subject line, there are many other people that can also help :P)

heys! admin, the link yur friend recommended doesnt work... =\ um, the bread board, does it have to have 356 holes? i can only find ones like 300 holes, 800 holes, etc.

can you tell me which parts on yur list MUST be the ones exactly on yur list? (e.g. does the Grid-Style PC Board with 356 Holes have to be that exact one, or can you use OTHER servos, or OTHER capacitors?) do you get it? sorry , its hard to explain. =[

The only part that must be exactly the same is the ATmega8.

Everything else can be substituted with something similar. If you arent sure, just post the part that worries you.

hey um will this ATmega8 AVR on the following website:

http://www.jaycar.com.au/productView.asp?ID=ZZ8753&CATID=&keywords=ATmega8+AVR&SPECIAL=&form=KEYWORD&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=

work? will it fit into yur 28 pin DIP socket ?

The ZZ-8753 will work.
(notice that it says PDIP, meaning it will fit in a DIP socket)

My bad... It worked a few days ago when I bookmarked it.

oops sorry, i thought you were the admin. hehe.. and um, its important that the e.g resistor stays at the ccertain ohm you stated right? or the capacitor stays the same type.

also would the brand affect the parts? wat if they wont fit in correctly.

nope, just close, like +/- 50%

check the datasheets for part measurements ;D
