Cee

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:

• start the Terminal activity and type:

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.

  • recommended the -j5 option for scons, but this may not be suitable for an XO.
