This is Newsletter #8 of the Open Instrumentation Project.
The OIP makes open-source software (written in vanilla Tcl/Tk) and
economical high-technology instrumentation hardware for students,
hobbiests, engineers and scientists. Current instruments include
oscilloscope (with spectrum analysis),
arbitrary/function waveform generator and Bode Plot network analyser.
Details of the project, hardware and software are at

We have just launched CircuitGear, a combination Oscilloscope,
Generator and Digital I/O. This is a 20MS/sec dual channel scope, 2MHz
arbitrary waveform generator, 2MHz hardware random noise generator and
digital input-output port, all fitted into the same pocket-sized
the DSO-101 oscilloscope.
CircuitGear is currently shipping with basic functionality in the
including spiffy new screen readout displays. We're porting spectrum
analysis, Bode plots (vector-network analyser), XY plots and all the
features of the DSO-101 scope and WGM-101 waveform generator to
and expect to post that software by the end of this month.
As usual for the Open Instrumentation Project, the software is Open
licenced under the GPL, and runs on the Windows, Linux and Mac
With CircuitGear, now possible for students and hobbiests to own - and
around with them - a complete electronics lab.
2. Laplace Cookbook
The Laplace Cookbook is a new paper in the Application Notes section
Syscomp web page. The paper is a mix of theory and practice, showing
determine the sine-wave frequency response and transient pulse
an electrical network. The paper shows how to use Maxima, an Open
Computer Algebra system, to generate theoretical results -- and how to
confirm these results with measurements using the Syscomp WGM-101
generator, DSO-101 oscilloscope and Bode Plot software.
3. National Instruments Labview
At the request of one of our university clients, we created Labview
that can talk to the Syscomp DSO-101 oscilloscope and WGM-101 waveform
generator. It's been tested under Labview running on Windows and Linux
platforms. If you're interested, contact us and we'll send you the
