The CEE by Nonolith Labs is a two-channel, two-quadrant, three-digit source measure unit.

It may be connected to an XO laptop for use in science and electronics education.

Ingredients

  • a Nonolith Labs CEE, with USB cable,
  • an XO laptop with 13.2.0 installed,

Recipe - Installing

The Nonolith Connect software must be installed:

sudo yum install boost libudev boost-thread boost-regex git \
                 scons gcc-c++ boost-devel systemd-devel asio-devel
git clone --recursive https://github.com/nonolith/connect.git
cd connect
scons # expect several minutes delay

Recipe - Using

To use the CEE:

  • plug the CEE into the XO laptop,
  • start the Terminal activity and type:
cd connect
sudo ./nonolith-connect
  • start the Browse activity and visit this link, and use pixelpulse,
  • when finished, quit Browse, and quit Terminal,

Test Case

  • configure voltage source, and capture data using Browse,
  • export to Journal and open in Write.

Experiences

  • the user interface refreshes at about five cycles per second, much more slowly than it does on a faster computer, but there is no loss of data on the curves,
  • zooming in works fine, but sometimes zooming out does not, a workaround is to start capture again,
  • building is expensive in time, but it should be possible to build the Nonolith Connect software into a Sugar activity derived from Browse.
