Kate (K8) Videos & Parts List

Hopefully this isn’t seen as a repeat post. I was hoping to attach this text to my video post, but it seems that isn’t possible.

I have created a new video of Kate (K8): https://www.youtube.com/watch?v=TiwLWbCwaH4

The previous one is here for those who missed it: https://www.youtube.com/watch?v=EOeZ-LNpqWQ

As a few folks have specifically asked, Kate’s parts list (as it stands today) is below:

· Arduino Mega 2560

· USB Battery pack (20000mAh with pass through charging)

· L298D H-bridge chip – Any off the shelf motor driver shield will be fine

· 2 small pieces of Vero stripboard – for the L298D, and the SR04 sensors – don’t combine – as motor noise is a problem

· Google AIY voice kit –or a microphone and a sound card for the Pi
