Let's Make Robots!

Swapshop-Blog Version

Ok, so ive made a robot, still workin on it. However, im lookin to the next one already, and for it, i need an arduino. Im dead broke, but i saw Swapshop in the forums, and thought it was smart! however, the most recent post was like 2 weeks ago, and i'm lookin for more traffic then that.

I was cleanin my room (for once) and found this stuff. im unloadin a lot of my old stuff for cash, and heres a bit of it...

Nicd Battery pack (1800 MaH)

2 Tamiya Gearboxes and Wheels

2 Leaf-Spring Switches

2 Radio-Transmitter like parts

2 IR detectors

If you want more batteries, i have a handfull. I'm willing to trade some or all or more for an Arduino Duemilanove. i'll ship anywhere in the world for free, as soon as i get some cash.

The battery alone is worth 25 dollars though, so don't be greedy please.

ok... ill do it. ill ship my stuff tomorrow or saturday. btw, pm me your adress...

I just need the wheels..

pm me your address too  :-)

 the wires that go into the back of the motor are missing. other than that, theyre set. hardly used.

ill maybe do it... what is atmega 168, whats the diecimila's specs?

-What year

-I/O pin #

and where in the world do you live?

You want the dieci and you're not even sure of the specs? Lol...

you really need to go the the arduino site my friend....

I live in Portugal. The Diecimila board has about one year and it is as new. The ATmega168 is the microcontroller chip.

Specs are:

Operating Voltage5V
Input Voltage (recommended)7-12 V
Input Voltage (limits)6-20 V
Digital I/O Pins14 (of which 6 provide PWM output)
Analog Input Pins6
DC Current per I/O Pin40 mA
DC Current for 3.3V Pin50 mA
Flash Memory16 KB (of which 2 KB used by bootloader)
EEPROM512 bytes
Clock Speed16 MHz


are they in good shape?

if so, do you want to trade by one Arduino Diecimila with ATmega 168?   :-)

are those tamiya gear boxes good? what is the reduction ratio?
