This instructable is going to be
about building an electronic drumset(not a MIDI sampler.),using an Arduino UNO R3.,
similar to a V-DRUM.It is code named KIDU.
(Kompact Intelligent Drumming Unit).Some of the items used may be names differently in your locality.ill try to put as
many pictures as posible.
I saw many instructables based on arduino and MIDI outputs.i thought of
making a completely independent instrument(ie with out a laptop).
(unlike V DRUM);
* Very portable and easy to assemble.
(the whole structure fits in a guitar case :-))
* The user can decide which sound each
drum sounds like.One can even record
a sound and upload it into the device
and make that sound from a drum.
(sound quality-16 MHz,16 bit mono)
* You can use as much storage space for saving the sound files.,
depending on the size of the SD card you use.
So a lot of sound styles can be included.For the sake of simplicity .,i used
5 styles of sound.
* There is no base-drum. Instead the kick pedal
contains a trigger.,that simulates a base kick.
* Total cost just a fraction of what the original
V DRUM will cost.I made it under 6000 rupees(~ $107).
* There are no unnecessary buttons and knobs for selecting the drum styles.
I have programmed it in such a way that.,
The drums themselves acts as the buttons.in this example.,i have used the snare
drum to trigger the count,.and the tom1 drum as the select key.
* There is no LCD display to guide you through selecting the drum style and the tones.
but KIDU will narrate every step.,and what style you have selected.
For example.,When KIDU startsup.,it asks you to enter the style count
using the snare drum.Then you hit the snare drum with the drum stick
less than 5 times,to select a drumming style,numbered from 1-5.
General Advantages :
(unlike acoustic drums)
*KIDU can play a large number of percussion styles.,depending on the
sounds that you have saved in it.
*You can directly record the audio output.,on to any device that can
record an audio signal,with out any ambient noise.for an acustic drum
you may need a studio to record it ambient free.
*You can practice it with out disturbing anyone.,by simply connecting
a 3.3mm headphone jack into the output socket.
*You can individually adjust the sensitivity of each of the drums through
program or a control knob.FSOS(for the sake of simplicity)i have excluded
the pots.I control their sensitivity by adjusting the threshold value in the program
prior to upload.
Step 1: Stuff Needed
# Arduino UNO R3
# SD card shield
# USB cable
# 5 V adaptor
# Micro SD card
# Piezo electric transducer(aka piezo disk)
# ribbon wire
# single core shield wire.
# Hook-up Wire.
# Parallel PCB.
# 2 contact jumpers.
# 3.5mm audio jack (male n female)
# Resistors- 1M & 10K (around 10 each)
* HARDWARE STUFF
# PVC PIPE(3.5cm and desired thickness) - 3 meters
# PVC T-junctions
# Thermocoal(real thick).
# Rubber like material(honestly dont kno its fancy name.:)
any material which gives sum rigidity and bounce.i bounght it from a
footwear manufacturing place.they use it for making the shoes soul. )
# Rexin(this material will be the artificial membrane.i used a black cloth
like material.u can use anything to make it look cool.u can even use leather
.it wont affect the way your drum sounds.)
# sumthing that looks cool..,to put your circuitary in.(i used an old laptop
cooler-pad.lot f room inside n looks awesome.)
* TOOLS NEEDED
# Soldering equipments.
# Cutting plier
# Wire Stripper
# Sissors (heavy duty thing)
# Thermocol cutter
# Hack saw
# Measureing instrament.
# Fevicol SR & SH(indian manufacturer for glue used for working with
wood and footwear industry.u can use what ever is used
for the same in your country :P )
# Insulation tape.
# Ducttape or cello tape or masking tape.
# sand paper(of variying grain size for metals.)
# M-seal(a material that can be molded in to any size and sticks)
# Spray paint.(Your choise.i used black.)
* SOFTWARES NEEDED.
# Arduino programming environment.
# SOX (command line format converter)
# FL Studio.
* OTHER STUFF NEEDED.
# A PC to program the Arduino.
# An amplifier to Hear the sound.
