Lighting control for artists

Paul Rudman has been working with artists since 2015 to add meaningful lighting effects to their work. Designing and building multiple lighting systems has led to the creation of a generic lighting controller that can be used to add programmed lighting to any artwork. The Radiance™ series of lighting controllers range from matchbox-sized USB-powered devices…… Continue reading Lighting control for artists

The birthday present 3: Done!

The finished lit frame works well, with the backlight colour correctly matching the air pressure. However, the effect was not quite as expected. First, I was expecting the colour to vary a lot, which is not really what happened. Air pressure doesn’t just go up and down every day. In fact, some values only occur…… Continue reading The birthday present 3: Done!

“Paul Conneally” 6: Exhibition

The art works Paul Conneally and Bearing Witness were exhibited from 12th January 2017 to 8th February 2017 at the Adult Education Centre, 50-54 Belvoir St, Leicester. I had wondered if the overall light level would be correct for an exhibition gallery. In my house the Poet appeared rather bright, but in the exhibition it was clear that they needed…… Continue reading “Paul Conneally” 6: Exhibition

“Paul Conneally” 5: Software

The software for this one is quite simple. Five patterns (lighting effects) are predefined. The software displays a pattern for a few seconds (the exact time is randomised) and then selects a different random pattern and fades to that one. This just repeats indefinitely. For example, to create the effect of light coming from above, the…… Continue reading “Paul Conneally” 5: Software

“Paul Conneally” 3: Electronics

The electronics comprise an Arduino nano as the micro-controller and a circuit board containing five surface-mount MOSFETs, used to switch the LEDs in response to the Arduino outputs. The MOSFETs are designed to be surface mounted. In other words, they are very tiny and designed to be soldered by applying liquid solder to all the…… Continue reading “Paul Conneally” 3: Electronics

“Paul Conneally” 2: Power and cooling

Power I had a lucky break! I discovered that if you give the 3 Watt LEDs 9 Volts they take 150mA, which is 1.35 Watts. And, given the smaller frame and having one LED per side per face (10 LEDs in total), 1.35 Watts is more than bright enough. This is very convenient, because, unlike with…… Continue reading “Paul Conneally” 2: Power and cooling
