Spectrograph of the broadcast radio spectrum imaged with an RFSPACE NetSDR software defined radio. The radio digitizes the whole 0-35 MHz spectrum, tunes to the 0-1.8 Khz band and performs a 65536 point FFT. The resulting resolution is 31 Hz per pixel. Each pixel is colored using a palette based on their signal strengt...

The 3 GHz CAMRa is the largest fully steerable meteorological radar in the world. The large antenna of the 3 GHz weather radar gives it an extremely narrow beam, only 0.25 degrees wide, resulting in an increased resolution (at 100km from the dish, the resolution of an 0.25 degree beam is 0.4km). It has dual-polarisatio...

Shot from Tour Montparnasse with the Eiffel Towercentered. Other famous locations such as the Arc or the Sacre Coeur are visible in the distance as well. The clouds that day were a little troublesome, which was unfortunate for the lighting (and transistions between photos) in the shot.
