Cad design drawn. Laser cutter sorted. Acrylic glued. Piezo buzzers mounted and connected electrically. All really exciting. Look how the stage has progressed over these weeks;
You may have been wondering what is firmware; it is the part of the AFM that sits between the software interface and the electronics that control the microscope. This means that we need to take care of two tasks: first, to listen to the interface and translate that into a signal that controls the scanning stage. Secondly, we need to measure the signal from the AFM and send it back to the interface. These tasks are accomplished using an Arduino and a microcontroller that we can program to read & write voltages. To do all these things at the right time and in the right order, we control the behaviour of the Arduino using C++ code, we wrote this over the past two weeks. Continue reading Firmware – Update
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.
Yesturday afternoon we took a group trip to the Shenzhen Electonics Market. It is very big, spread out over many floors and a few blocks. With minimal time the group manged a couple of floors in an hour and half!
Drones, power packs, heat detectors, particle detectors and a variety of cables were all purchased. Until next time…!
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
