MLange is located outside Ottawa, Ontario, Canada, and is currently ordering electronics and eagerly awaiting the Inventables Mechanical Kit.

Ordering parts in Canada

The best prices for ordering parts in Canada are mostly found by ordering from US suppliers and dealing with the tax and duty incurred from importing into Canada; however, RobotShop.ca offers quick shipping from Montreal, QC.


Upgrades Planned (in no particular order)

  • Self-Powered Arduino (Not USB-powered)
    • 1x 24VDC-to-5VDC switching mode power supply (Digikey.ca)
  • Dust Brush
  • Emergency Stop Button
    • 1x PowerSwitch Tail II (I have the original PowerSwitch Tail) connected to the spindle power cord
    • 1x Red Pushbutton Switch (In the parts bins here somewhere, really) to pull PowerSwitch Tail high/low(?) (OFF) when depressed, and trigger the Arduino to "Shut. Down. Everything", including proper power-down of steppers(?)
  • Limit Switches (for the X and Y axes)
  • User Interface (for use without attached computer)
    • 1x LCD Shield (ITead, DFRobot), and Adafruit even has an I2C version (the LCD and buttons together only take two pins)
    • OR 1x VFD Display (AllElectronics)
    • 1x SD Card Shield (ITead, SEEED) or SD Card breakout (ITead)
    • AND/OR 1x Bluetooth shield/module (ITead, SEEED) or Xbee Shield (with Bluetooth or XBee module) to stream wirelessly (and/or perhaps for remote progress monitoring?)
  • Arduino Enclosure
    • Acrylic(?) box with fan and filter for venting
    • Touch sensors under the acrylic to allow for UI use without letting shavings/particulate/etc in?
    • OR maybe one of these for the "GO" button: (Rounded: BGMicro / Flat: BGMicro)
  • Wire Wrap
    • Wrap wires with spiral-wrap tubing (Digikey.ca) to prevent pinched wires

Interesting Items of possible use

  • 24-48VDC @0.4A -> 12VDC @0.4A converter, PCB-mount: Goldmine-Elec... Still a bit high to power the Arduino from, though. Hmmm...
  • OR a small switching power supply from an external hard drive case: Goldmine-Elec.. Even has a USB port that the Arduino could patch into
  • NICE power supply, but the international shipping and order minimum doesn't do it for me, but US folks, check this out: (Herbach & Rademan - Ascom Frako #77-527-2300)


Companies that ship to Canada

This is far from an exhaustive list, of course, just a few favourites. The prices for things vary widely by store. (I don't have any vested interest in any of these stores, I'm just listing them for reference. Feel free to merge this into a larger list of stores/resources) Pro Tip: Don't ever import something into Canada by UPS or Fedex unless absolutely necessary. Go for USPS whenever possible. Even if it's a bit more expensive to ship, it will save you a lot when you take into account UPS's rather high brokerage fees.

  • Electronic Parts (Canada)
    • DigiKey Canada (Ships from USA, but they will bill Canadian GST/PST/HST so you won't get charged brokerage fees and such by the UPS driver)
  • Electronic Parts and Assemblies
  • Electronic Surplus (US)
    • AllElectronics, Santa Clara, CA (They call you with a shipping quote to Canada if shipping is over $10. Website doesn't calculate shipping. $7.50 minimum shipping and handling. Offers USPS and UPS to Canada)
    • Alltronics, Van Nuys, CA (Offers USPS and UPS to Canada)
    • BGMicro, Garland, TX (USPS to Canada, $7.50 minimum shipping and handling)
    • Electronics Goldmine, Scottsdale, AZ (USPS to Canada)
