Ordering parts for the $50 robot
« on: July 04, 2010, 11:40:55 PM »
Hello All,

Recently I started wanting to delve into electronics because i really needed something to do over the summer and I didn't want to just sit in front of the TV all day.

I've been looking at the $50 robot tutorial and I think I understand it pretty well.
My parents don't like ordering stuff online and so I need to order EVERYTHING that I need all in one large order.
-It can be from several websites, but they don't want me to order stuff one day then order more stuff another day, etc.



So, my final parts list:

ATmega8 AVR:
http://www.sparkfun.com/commerce/product_info.php?products_id=210

5V Linear Regulator:
http://www.sparkfun.com/commerce/product_info.php?products_id=107

28 pin DIP socket
http://www.sparkfun.com/commerce/product_info.php?products_id=7942

220uF+ Electrolytic Capacitor
http://www.marcospecialties.com/product.asp?ic=C220M25VA

.1uF Ceramic Capacitor
http://www.sparkfun.com/commerce/product_info.php?products_id=8375

36 position breakaway male header
http://www.marcospecialties.com/product.asp?ic=CM10036

340ohm resistor
http://www.radioshack.com/product/index.jsp?productId=2062341&clickid=cart


LED
http://www.sparkfun.com/commerce/product_info.php?products_id=533

CdS Photoresistors
http://www.radioshack.com/product/index.jsp?productId=2062590&clickid=cart

Grid-Style PC Board with 371 Holes
http://www.radioshack.com/product/index.jsp?productId=2102844&clickid=cart

Enclosed 4 AA Battery Holder (with On/Off switch)
http://www.radioshack.com/product/index.jsp?productId=2062253&clickid=cart

6v 1400mAh NiMH Battery
http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXMUE1&P=7

AVR STK Serial Port Dongle Programmer
http://www.sparkfun.com/commerce/product_info.php?products_id=14

HS-311 servo
http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXDEL5&P=6

1.62Kohm resistor--the link is a 1.8k resistor, is that okay to use instead? it would save me tons on shipping costs
http://www.marcospecialties.com/product.asp?ic=R10W1.8K


So there's what I have.

If someone could please check those links, make sure the voltages work out and stuff.
Thanks a ton for any help!

looks ok :)

however just a suggestion, this circuit has room for expansion, it can pretty much become your robot testing platform, so you may be upgrading the MCU after a while, or be switching between different MCU's, this can be bad for the pins and the for required to push them in can also damage them.

I've fallen in love with ZIF sockets (Zero Insertion Force), can be a little more expensive but worth it for that type of application, however on the note of prices for them, I recently bought 2 for $0.01 on Ebay, so have a look there if your interested.

Hope this helps

-Alfa

The resistor should be fine.

Although, do you already have a programmer, and a snap connector for the 9V battery?

If not you might want to buy them.

Hey guys,
thanks for the advice.

for the snap connector:
http://www.sparkfun.com/commerce/product_info.php?products_id=91
Should do the job, right?

But what is the 9v battery powering? After re-reading the tutorial, It only mentions a 9v battery as a separate option for powering it(instead of the 6v battery)
Do I use it for something else?

The connector on the end of the 9V snap connector concerns me...
You can always cut it off anyway, if it doesn't fit and solder it directly.
You can also use terminal blocks as well.

The 9V is used for powering the circuit, the battery holder for the servos.

Although, do you already have a programmer, and a snap connector for the 9V battery?

Sorry, I didn't see the Dongle programmer on the list. Must be my eyes...

EDIT: Whoops, another thing I didn't see. You won't need both the NiMH battery pack, and the battery holder and 9V.
They're two separate choices.

If you plan on doing robotics for a long time, you might want to go for the NiMH battery pack. But the battery holder plus the 9V is cheaper.

Ah, that makes a bit more sense.
Thanks for the help guys! Now I'm ready to order my parts    ;D

Description from the site:

The Society of Robots has a great beginner robot tutorial called the "Step-by-Step Robot Tutorial under $50". "Ever wanted to build your own robot but didn't know where to start? Here is your chance! I will outline step by step exactly what to do to build a robot for under $50." The robot tutorial guides the first-time builder through construction of a low-cost robot. The tutorial describes the electrical and mechanical systems of this low-cost robot.

The CGSORKIT1 contains the electronic parts for the $50 robot (except for the servos) all collected in an easy-to-purchase pack. No more wondering if the parts that you selected are right for the $50 Society of Robots tutorial. There are several benefits to buying this kit. First, you save some money over getting the parts all by themselves. Second, this kit contains more than the bare minimum for the $50 robot tutorial - wire, solder, LEDs, extra resistors. Third, the CdS cells are matched to each other - no guessing which ones are the same in the surplus set from Radio Shack.

Fourth, the ATmega8 AVR microcontgroller comes programmed with the Arduino bootloader, if you choose to develop with that environment. And, even if you don't, having that bootloader in the chip helps with debugging as the bootloader will blink PB.5 on power-up.

Kit Item         Quantity
Printed Circuit Board         1
ATmega8 AVR, DIP package         1
Socket for ATmega8         1
CdS Photoresistors (matching)         2

Red LED         5
Green LED         5
Yellow LED         5
1.62 k ohm Resistor         8
330 ohm Resistor         8
30 position single in-line header         3
220 uF Capacitor         1
.1 uF Capacitor         3
3 position crimp header         3
Crimp pins         10
Lead-free Solder         36 inches
Misc wire, 24 gauge, solid         20 feet



The CGSORKIT1 does NOT include the two HS-311 servos.

Man, I wish I knew about that kit. Would've saved me some money.
Oh well.

Gearmotion,

Thanks for that link! That helps with all kinds of complications, and even comes with a little extra!
Plus it's cheaper than all the separate things.
Definetely going to be ordering from that website :)
