It has been a while since the last electronics update when we had first got the focus error signal out. All the circuits now work together and are getting developed.
How DACs work, By Isabel Bennett, PhD student, UCL
Embarking on the L2N project as a non-engineer I knew I was going to be challenged and learn a great deal. Even as a user of AFM for my PhD, my experience in the electronics that go on “behind the scenes” was limited.
I wanted to be stuck in at the deep end: sink or swim, I thought. So I signed up for the “firmware” stream, which was the team focused on programming an Arduino microprocessor to coordinate the desktop programme interface with the electronics of the AFM. My experience on an Arduino had until then consisted of turning a series of blinking LEDs on and off in response to a switch. Not advanced stuff.
