Quick Scope brings an easy to use oscilloscope interface to the classroom. Leveraging Vernier’s LabQuest® and LabQuest Mini® with a webservice Quick Scope enables students to collaborate on experiments and still explore the results individually. Many thanks to Vernier for making their API available for this project.

The Quick Scope Server is composed of the ScienceAtHandServer.jar and the Vernier NGIO native libraries. The Vernier libraries are contained in the LabQuest Software Development Kit. Place the jar file and the native libraries in the same folder and run the jar file from a command line. On OSX the command line to run these is “java -d32 -jar ScienceAtHandServer.jar -port port_num -samplerate sample_rate” and on Windows its “java -jar ScienceAtHandServer.jar -port port_num -samplerate sample_rate”. The server defaults to port 8080, the port can be specified with a -port portnum option on the command line. The sample rate determines the maximum sample rate for all LabQuests attached to the server. The default sample rate of 10000 samples/second allows for about 100 – 200 probes on a wifi G system.
