Now accepting USD

This morning I upgraded our shop to now accept USD or CAD currencies. Just select the currency you want from the drop down list at the top of the site and all the numbers should adjust. Even better, you can pay directly from your paypal with USD, avoiding that nasty conversion fee.

2015 Projects

Now that I’ve got the M3 to Prusa i3 out of the way, my new priority is a gearbox I’m going to need to build my next robot arm. From January to end of March I have three university students helping me build the arm. Around that as I have time I’ll be programming my first custom PCB and bringing out another new robot that’s still deep under wraps.

Maybe after all that I’ll take a break for summer. LED art to Burning Man 2015, anyone?
