The pcDuino needs 5V 2000mA to run stable while the Raspberry Pi only needs 5V 700mA. I planned on using multiple USB devices so a USB hub was a necessity. After browsing a few local electronics stores I found that a few powered USB hubs have a specific port that...

Wheels and Tires

I found and purchased the largest wheelchair wheels and tires I could find that would fit my motor shafts and wheel hubs. I do have fears that they wont have enough traction on grass to preform pivot turns but eventual testing will let me know if I need to rethink the...

Wheel hubs

I needed a way to attach drive wheels to the electric wheelchair motors I purchased on ebay. The motor shafts were an odd size and nothing I could source locally would fit. I did some research and was back on ebay searching for the wheel hubs made specifically for the...

Electric Mower DC Motor

I was lucky and found this DC motor along with the controller and charger on ebay around the same time I purchased the AC mower. Converting to DC allows me to power the motor with batteries. This motor will have its own power source separate from the drive motors'...
