Capture what you build as your build it. This afternoon we were delighted to welcome Tiffany on skype to talk to us about a new website she designed, named Build in Progress.  It lets you share what you are building as you build. Build in Progress is designed to help you document your project as your developing it. We are hoping to show the LEGO2NANO project using this platform. Continue reading Build in Progress

Electronics for Dummies (or biochemists)

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.
