Leo has devised an innovative solution for the council of Alkmaar to measure air quality and noise pollution in the city. By utilising acrylic, he has constructed lamp post modules that also include a GPS system. As a result, they can pinpoint the exact location of noise disturbances, such as those coming from pubs or heavy traffic. This clever system helps address resident complaints more effectively and improves the overall liveability of the city.
The project
Leo has developed units comprised of various sensors: a particulate matter sensor, air pressure, temperature, humidity, and lux sensors to measure the air quality. A microphone measures the noise, and an antenna transmits the data via the ‘Lora system’. The modules were largely inspired by noise disturbances in residential areas and during events. With a custom-made bending tool, Leo could accurately mould the acrylic to shield the antenna and microphone from rain.
Leo: “With my modest bending tool, I can bend acrylic very precisely which works perfectly for this project.”Step-by-step guide to create this yourself
steps
-
Assemble
Put together a bending tool by screwing two metal plates together with 8mm bolts.
-
Bend
Use this tool to accurately bend the acrylic into the desired shape.
-
Trim
Trim the angled edges with a Stranley knife and saw the corners with a hacksaw.
-
Drill
Carefully drill holes with 2 mm and 4 mm drill bits for extra precision.
Materials and tools used
Leo’s tips for others
“It’s better to experiment with a large sheet of acrylic first, so you can be sure you’re satisfied with the shape before finalising it.”
