Here are some more recent images and videos of the circuit Ed has put together for my piece. I’m very excited to install it in the doorway. Fingers crossed it goes smoothly! There have been a few technical hitches (see video at the bottom).
As Ed will tell you, its been a mission to get the circuit working properly. Through his extensive experience in electronics he’s managed to get it working, whilst correcting an online Instructable! Success all round. I’m incredibly appreciative for his help with this. From my experiments last year with sensors and LEDs, to using an LED screen, to Ed’s Halogen circuit.
The circuit will allow for my main concept across these experiments to come to life. The reaction of an artwork to its audience.
Originally, the plan was to make a piece on Perspex with electrical tape. In recent weeks, I’ve realised that this can be done in a much better way. I’m now getting an acetate print the size of the doorway. This will be placed in between a white scrim in the doorway and the halogen lights. As the viewer approaches the door, the door will illuminate, revealing an abstract impression of internet connections. This aims to replicate the way that we trigger our devices to access information on the internet.
As you can see from the photos below, there have been a few different prototypes.

Disaster: Exploding Resistors on the first Circuit Design.
I met with Ed before the Low Res. We discussed how to organise the electronics for the final show. I’m still set on including a circuit that uses an Ultrasonic sensor to reveal an element of the work as the audience approaches, but the idea has simplified slightly. Instead of using LEDs, the plan is now to use Halogen bulbs as they’re brighter and can be dimmed nicely. I’m upgrading to a stronger Ultrasonic Sensor that will be embedded in the piece.
Ed attempted the circuit etching last week in the Studio, but we had some problems with the UV lamp. He’s going to attempt it again in his own time as I’m away until the beginning of April. I’ve bought and tested the scrim that these lights will be behind. I aim to create the shadow play with large perspex sheets, duct and electrical tape. The image created in the shadows will reflect a similar aesthetic to the architectural, linear images I’ve been working with. (See below). The sensor will be embedded into the doorframe of the final work. (More details on this to follow).
I will publish a post of the working circuit when I can to capture each component of the final work separately.
Arduino / LEDs Test:
1. LED A to B when sensor is activated.
2. LEDs brighten as distance sensor is activated.
3. Reflective Background, LED shines through Prototype cutout.
4. Blocking projection light and successful back projection.
