Here’s Ken Olsen’s write up of the project he shared on last week’s Show-and-Tell. From The Maker’s Box:
My latest project was designing and building a circuit board on the web-based Circuits.io. They have made it super easy to make a PCB in comparison to using Eagle Cad and sending files to a boardhouse.
One of the first things I did with my Raspberry Pi when I got it was an Adafruit Learning tutorial on analog inputs. The Pi doesn’t have analog like the
Arduino, so it needs a little help. Using a MCP3008 on a SPI bus can get
you 8 channels of 10-bit analog. Take that Arduino! At the time, I
used Adafruit’s cobbler board which makes breadboarding things a snap.
This looked like a perfect project for trying out Circuits.io, and it was….
