eSketch PRO

eSketch PRO is a powerful schematic capture and simulation application specifically designed for the ultra fast rendition and simulation of frequency-shaping analog circuits such as preamplifiers, amplifiers, active filters, passive filters, crossovers, equalizers and tone controls. eSketch is a specialized program for circuits containing capacitors, inductors, resistors and op amps. It does not provide transistors, diodes or other non-linear devices.

The programs simplicity of use and speed of execution provide an “electronic sketching” environment in which the effects of changes in layout, component values, component tolerances and op amp Gain Bandwidth can quickly be determined.

Schematica capture:

file merging
importing of (registered) Filter Wiz PRO files
rapid component (device) placement
fast editing of component values
op amp device database provides Gain BandWidth values for over 600 op amps
full circuit editing capabilities such as copy, cut and paste
annotation with text boxes and markers

Analog circuit simulation :

automatic indication of when circuit is ready to simulate
view two graphs simultaneously
two voltage probes - view both, either, or difference
save previous traces to view up to 13 voltages or currents at once
amplitude response (real, imaginary, dB, volts)
phase and group delay responses
input impedance
component current, impedance and power dissipation
Sensitivity of output voltage to changes in component values
transient response to impulse, step and “staircase” inputs
“ideal” and “real” op amp models
Monte Carlo analysis
Parameter Sweep analysis
pole-zero placement

Celestia

Celestia is the free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.

Unlike most planetarium software, Celestia doesn’t confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.

All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A ‘point-and-goto’ interface makes it simple to navigate through the universe to the object you want to visit.

Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that’s not enough, you can download dozens of easy to install add-ons with more objects.
