Today I finished up the installation and filmed and recorded everything.  I started by connecting the copper wire and thread to the speakers, which I had already set up and ready to hang. After that, I got ready to attach the battery and Arduino to the ceiling. Initially, I was going to attach them to…

Now that I’m done testing, I have to do a lot of things quickly to actually set up and play. First of all, this time I had to shorten the sequence I made before because the battery problem limited the playing time, insulate it to prevent unnecessary noise and short circuit, and organise the installation…

Today I received a nickel-metal hydride battery and put it to the test. I’ve had a lot of failures in this project, but this was the batteries’ things that gave me the most frustration. I needed to understand voltage and current, and I had to pay a lot of attention to the total capacity of…

The previous 9V batteries were carbon-zinc batteries, and due to their insufficient output, they didn’t function properly. The batteries I purchased this time are alkaline batteries, which provide better output than carbon-zinc batteries. Thankfully, they work well. The output is sufficient to make the speakers strike the metal plates effectively, and the sound is loud…

Today, while waiting for the ordered alkaline batteries to arrive, I plan to design a sequence and layout for a realistic play. First, I worked on the sequence and layout while waiting for the batteries. I started by thinking about the placement of the speakers. The space where I plan to exhibit is my living…

I finally got all the steel plates drilled, and now I’m going to combine all the parts, including the speakers and the steel plates, to see if the 12 speakers will work with the cord I wove.  Firstly I joined the speakers and all the steel plates together, unfortunately I was a bit short of…

Today I did a quick test and talked about my work with Milo at the Uni.  Firstly, I tried to adjust different variables to get different sounds out of the steel plate, but so far I haven’t found anything that works except the thickness of the plate. I had previously thought that the distance between…

Today I received a 9v battery, and I’m going to drill holes in 2mm and 3mm steel plates to test the battery and compare the sound. The first time I connected the 9v battery to the speaker through the relay module, I had the same problem as last time; no power to the speaker, only…

I got a mini screwdriver to connect the audio amplifier to the speakers, an electric drill to drill through the steel plate, and a relay module to send external power to the speakers. I’m going to experiment with these three things. I couldn’t use the LM386 before because I didn’t have the right screwdriver to…

Today I’m going to do an experiment with the arrival of steel plates, a large speaker, and jumper wires for an audio amplifier.  I purchased 10cm x 10cm sheets of steel in thicknesses of 0.8mm, 2mm and 3mm, with the intention of using the thickness of the sheets to create different sounds. The original plan…
