Robot parts

Posted on July 24, 2011

I’m building a 4×4 robot. I’ve never done any electronic/mechanic projects before, so I’ll learn and make mistakes along the way.

Here are some of the major parts (minus sensors) that I plan to use.

Boarduino Specification:

• Designed to plug into a breadboard for easy prototyping
• Petite size, only 3″ x 0.8″ (75mm x 20mm)
• All ‘standard’ pins are brought out – Digital 0 thru 13, Analog 0 thru 5, ARef, 5V, Ground, Vin and Reset
• 2 LEDs, green power and red “pin 13″ LED just like the Arduino Diecimila
• Standard Reset button
• ATmega328P, running at 16.00 MHz, just like the latest Arduino, the Duemilanove (note that the product photo above hasn’t been updated)
• 6-pin standard ICSP header
• Standard 2.1mm DC jack (just like the original Arduino) with 5V regulator to run on 7V-17V power (DC)
• USB or External power, selectable with a jumper (just like original Arduino)
• 1N4001 diode protects against using incorrect wall adapter
• 6-pin header at the end for a USB-TTL cable
• Auto-reset capability when used with a USB-TTL cable
• Available as a low cost kit with standard parts, so its never out of stock
• All through-hole parts are easy to solder

Motor Specification:

• Horse Power Cont.: 5W
• Voltage/current: 12V DC
• RPM: 300
• Reversibility : Reversible
• Length of Motor (including spindle): 76.1mm
• Diameter of Motor (D): 37mm
• Length of Motor Body(excluding spindle) (BL): 56.4mm
• Full Length of Spindle (SL1): 19.7mm
• Length of Spindle (SL2): 14.6mm
• Length of Spindle Flat (SL3): 13.5mm
• Diameter of Spindle (SD): 6.0mm
• Height of Spindle (no a flat ) (SH): 5.4mm
• Weight: 186G

Wheels Specification:

• Plastics Wheel Rim
• Diameter: 60 mm
• Width: 50 mm
• Hexagonal joints: 12 mm
• Rubber Tires
• Diameter: 130 mm
• Width: 57 mm

MSP430 in VirtualBox on MaxOS

Posted on June 16, 2011

If you are using MacOS and you want to write some code for MSP430 the easiest way is to use VirtualBox and Windows.
To allow VirtualBox to see development board, you need to load some drivers, fortunately someone already wrote them, so just follow this link to install them: http://mspdebug.sourceforge.net/faq.html#rf2500_osx
then reboot and connect the board in VirtualBox. After you can upload and debug code.

So two bytes are walking to a bar after work…

Posted on December 19, 2010

While they’re walking, one says to the other: “Are you all right? You look kinda sick.”

The other responds: “Yeah, I’m fine; I’m just feeling a bit  negative after our shift.”

My new company

Posted on December 15, 2010

I started a company Gemstones Design  http://websitecenter.ca/ with my friend David.
We specialize in creating light-weight, attractive, functional websites that work.

So if you need an application, website or a web app give as a call.

It is a bit different from my previous jobs at IBM ;-) (developing java VM and class libraries) but I want to run my own business and we have all the expertise to make it big (not only in web design and application but in other markets as well).

Specialties

web development, website design, application development,
