Interactive Devices Final Project: Obsoleting Instruments Process 1.
After the Initial concept, I’ve 3D modeled the Laser mount and Photoresistor mount.
all the 5V Laser Diode pushed into the 3D printed Laser mount
Laser mount with 5V Laser Diode
After painstakingly solder every + & – wire on a PCB board cut into half
Its really bright if I used 5V, 3V Supply is what I actually need
Hot Glued into the top of the mount to prevent wire breakage
And after the Laser mount was done and working great, I went ahead to print the Photo Resistor mount.

It is designed to hold the photo resistor and allow the connector of each Photoresistor to be protruded out so that I could solder the circuit with the pull down resistor right on the module to remove the need for having a breadboard in the Telephone as the space will be limited in it, and i guess this will be the more efficient way of doing thing while making sure all connections are secured.
Placing each Photo Resistor into the PR mount
It somewhat look like centipede.
the Laser mount and the PR Mount.
Soldered 10K resistor to every Photo resistor to make a pull down resistor circuit.
After it’s done, I tried to connect them together
my draft and study of piano keys
And the Laser shoot into the PR mount just like I hope it to work
after everything was soldered using telephone wires
The soldering took some time to complete but luckily for me, I only need to do it once, or so I thought… (some part broke when I bring this to school so I did re-solder it again.)
Version 1 of the connector, it doesnt stay in the Arduino Mega as it is loose.
Version 2 – all soldered on a straight jumper pins
After I brought it to school, a few connections broke so I did Version 3
Version 3 looks and work great. I HOPE THIS IS THE LAST TIME I SOLDER THIS!!!
I also purchased an old Landline Telephone on Carousell, I must say that Carousell is a wonderful thing.
The Carousell page
and I bought it. Its so similar to the one in my previous post!!
And I opened it up to check how much space there is and what parts could be savaged.
In the end, the only part that could be reused is the phone’s body, the speaker/handle/hearing thing, the buttons and the telephone wire.
Meanwhile, I started to write the code on Arduino for the Laser and Photoresistor.
