WEEK 18:Applications and implications

The aim of this week was to propose our final project and share the answers about all the questions below that showing how long am I , And its function and cost

At first I have a different Idea about my final project about making a "signal jammer" untill my input and output week through that weeks I got different Idea of making a "Digital Drum" so this week I am going to plan the final project and document units that covered.

1.What will it do?

Digital Drum consist of electronic or digital sound modules which can produce synthesized sound.Here I decided to upgrade it into more atractive by making the drum like 3 rows and 3 columns in each columns where we make a touch the beat will produce and each columns are with LED lights that produce light in each touch will make every touch more attractive with the sound

I planned make that possible through by touch sensor to give both the output light and sound

2.Who's done what beforehand?

I have seen a lots of project on the web and I got an idea about it then I searched the notes of the beat In first it seems very difficult but I think the below project can help me from that


In this he is using "pizoelectric" here I can use sensor insted of that and also will get some beat notes from here can upgrade all into my project model,even though I couldn't see more ideas about my project it seems very unique

3. What will you design?

. I want design a box with 3*3 rows and colums it consist with 2D and 3D designing

. Also want to design a PCB board by taking the maximum out pins

I want these designs more importantly, In going with my project If I want to intagrate anything I will go with that designs also

4. What materials and components will be used?

. Touch sensor/pizo

. Speaker and Amplifier

. microcontoller,capacitor,Resistor

. 12 mm plywood sheet and Acrylic sheet

. 18 LEDs (8mm)

. Connecting wires

5.Where will come from?

Most of the parts of my project are from fab inventory execpt LEDs ,So I want to by it from local shop or online .Then I decide to make Amplifier and capacitive touch sensor myself with help my instructor.

other body parts can make through shopbot and my board can make in the lab easly ,all the components are there for the making of my board in fab inventory

6.How much will they cost?

Most of the things that I am using self made and from fab inventory so I take the cost of the components that I want to make my parts

ATmega board around 4.5 USD

LEDs 8mm around 1 USD

plywood sheet and acrylic sheet 5.5 USD

also including the other expences as 8/9 usd at maximum my total will aproximately equal to around 20 usd

7.What parts and systems will be made?

. Body of my Digital Drum made by 12mm plywood

. upper portion with trasparent acrylic sheet

. Electronic board by pcb milling

. vinyl stickers

. capacitive touch and Amplifer is making by myself

. Embedded programming

.3D printing

Almost all the parts can make in the lab for my final project

8.What processes will be used?

. CNC cutting on shopbot by opening the design file as.dxf in vcarve

. laser cut the acrylic sheet by opening the design file as.dxf in Trotec laser cutter

. Drawing the desing in eagle and milling in the Roland module

. vinyl stickers in vinyl cutter through the .png file exported from inkscape

. capacitive touch and Amplifer is making with tha available components in the lab

. Embedded programming using ARDUINO

.3D printer

9.What questions need to be answered?

I am not sure that here How will the sound comes out through the speaker?(the sound is like drum beat)
Wanted to check the strength of the capacitive touch weather it is detecting or not
If the capacitive touch is not applicable then I want go forward with pizoelectric, at that time I want to find the beat strength in each stress
The programming code with beat notes seems some difficult so may be I need some help in there

10.How will it be evaluated?

It will be evaluated by the progress in my work in each stage of final project ,I have implimented the application of all machine in our lab as a perfect way also it can be evaluated through funtionality of my final product
