The latest instrument from the Phoenix-Project stables
Your Lab @ Home … A tool for learning science by exploring and experimenting.
A wide range of experiments ranging from elementary high school experiments to post graduate levels have been designed and documented along with graphical interfaces.
All code is open source, and easily modifiable to adapt to new experiments.
1MSPS oscilloscope, with input ranges up to +/- 16 Volts
automatic as well as manual range selection down to +/-20mV. AC coupling via a toggle switch, and a dedicated microphone input.
12-bit voltmeters and data loggers available on all 7 analog inputs
Frequency measurements up to 8MHz.
Time interval measurements, with multiple edge recording features. Resolutions down to 15 nano seconds are available.
Capacitance meter from pF to uF range.
It is a hardware & software framework for developing science experiments, demonstrations and projects without getting in to the details of electronics or computer programming. It converts your PC into a data acquisition and control hub for a science laboratory.
The PHOENIX (Physics with Home-made Equipment and Innovative Experiments) project was started, in 2005 as a part of IUAC’s outreach program, with the objective of developing affordable laboratory equipment and training teachers. The design of ExpEYES combines the real-time measurement capability of micro-controllers with the ease and flexibility of the Python programming language for data analysis and visualisation. It also functions as a test equipment for electronics hobbyists and engineering students. Software for all products from PHOENIX are distributed under GNU General Public License and the hardware designs are under CERN OHL.
Over 70 different experiments with dedicated graphical user interfaces, Schematic diagrams, and help files are ready to use. The individual function calls can also be accessed from Python scripts, and several code examples are included. The code is compatible with Linux, Windows & OSX
Ri = 1K Ohm and Rf = 10K Ohm.
The WG amplitude is set to 80 mV, but you may try a 1 volt input to observe the clipping of the the output, since it exceeds the op-amp supply voltage of +/- 6 volts.
This experiment can also be done by running this Python Code. The output of the program follows;
import eyes17.eyes p = eyes17.eyes.open() from pylab import * p.set_sine(200) p.set_pv1(1.35) # will clip at 1.35 + diode drop t,v, tt,vv = p.capture2(500, 20) # captures A1 and A2 xlabel('Time(mS)') ylabel('Voltage(V)') plot([0,10], [0,0], 'black') ylim([-4,4]) plot(t,v,linewidth = 2, color = 'blue') plot(tt, vv, linewidth = 2, color = 'red') show()
The voltage across the diode is measured on A1. The anode of the diode is connected to PV1, through a 1k resistor. Voltage at PV1 is incremented in steps and at each point the voltage across the diode is measured. The current is calculated from i = (PV1-A1)/R. The diode used is 1N4148, silicon diode.

Download the ISO image , that is a modified version of Ubuntu 16.04. MSWindows users may download the program rufus and use that to make a USB pendrive bootable with this ISO image. After making the bootable pendrive, shut down the PC, insert the pendrive and select the boot device while starting again. For PCs having Windows 8 or later may have UEFI and secure boot enabled in the BIOS. You need to disable secure boot and choose Legacy mode instead of UEFI, from the BIOS settings. The keys to press to enter BIOS depends on the brand of the PC you have (for HP it is ESC key, for Lenovo Fn+F2 and Fn+F12 to select the boot device, more info HERE)
The software is available from the standard Debian software channels, and can be install by searching for ExpEYES from the software center.
Alternatively, you can get the deb from here, and install it using gdebi
sudo gdebi eyes17-3.8.0.deb
A standalone installer can be downloaded from here
The package includes the python interpreter, as well as all required modules and drivers.
