Plotting Orbits – Part 1
Using the orbital equation it is possible to plot the orbits of planets, moons and other objects to a reasonable degree of precision, this however only works for visualising orbits that are relatively stable or at an instant in time. Accurate orbit data (ephemeris) can be obtained from NASA JPL Horizons system, in this case…

Measuring Amplifier AC Impedance
Knowing the impedance of an amplifier or any electronic circuit can be very useful, for lower frequency applications it’s desirable to have the source impedance be much lower than the load impedance to minimize voltage drop, in RF applications and where maximum power transfer is needed it’s better to match impedance to avoid reflections, the…

Fosi Audio DAC-Q4 Review
I’ve been having a problem with PC audio noise for quite some time, the front audio jack in particular was very susceptible to interference, primarily from my GPU, I decided to get an audio DAC to fix the problem, specifically I wanted one with an optical S/PDIF input since this provides complete electrical isolation which…
