Daily Life

I will be showing two videos where I find that though these installations are simple, they somehow manage to interest me and let my daily life be more exciting if we had that.

This person rigged up a camera to with Pure Data to detect motion and control servos to rotate heads attached to the front window mannequins. Now they watch back at people pass by on the sidewalk.
I always thought it will be interesting to see non living thing looking back at me and I like the idea as even though it is just a simple installation, it will catch people’s attention and at least have a second glimpse of the clothes. This idea can also work for many other things like the lion statues that some places have. It is nice as they are suddenly “alive” and i like to observe how people probably the kids will interact with it.

Audiovisual on ‘Esteles’ (Led Tails), an interactive installation that visualizes pedestrians paths/actions in a public space by proposing a reflection on the interaction between people and public space.

14 infrared sensors detect people passing by, codifying the information into a wall with 80 handmade led’s lights, embedded in resin. All control is done by installing a Peggy2.1 motherboard programmed with Arduino.

‘Esteles’ won the 1st prize in Public Project 2008 and has been produced by artAtTheLab at Anne Frank square, in the Gracia district, Barcelona.

Audiovisual realized by Enric Recoder, Teresa Duran, Sakari Laurila & Xavi Satorra in 2009

My thought for this is it will be cool to see these kind of lights rather then those streetlamp and how I hated the colour. I know even though this may cause more money but what about ion? This installation can be placed in mrt and at least people will not be bored on the way home.


Bjcem 2009

This video that I found, they actually have sort of like a exhibition on arduino. Among all, these are the four that the person filming like most.

The first one to me is quite normal and expected but I like the way it can still have the continuous movement of the artwork. It makes it very elegant and expensive.
The second one is the one I like most. Even though it is simple usage of arduino, I would never think that cooking can actually “creates” my own world etc. I like this concept because everyone’s dish will taste different even when given the same ingredients and the person manage to convert that into something visual and interesting.
Third one would be the spray which I guess everyone will know and the last one is just something usually with the mouse being the light. However, I really like the idea of the light as the whole concept just flow with the light have such dreamy and “in the space” feel.

High Speed Photos


As I am super lousy at taking shutter related photos, I went to see if arduino can helps and the above pictures are what I found from a website that uses the arduino to take high speed photos but too bad not a video. It uses a laser sensor and a sound sensor. Taken from the site,

Laser Sensor

This first sensor uses a cheap laser pointer and a photo resister to detect the laser’s light. The software is setup to trigger the flash when the laser beam is broken. The software also turns off the laser so it doesn’t show up in your photograph. Think of it as an electronic trip wire. This is great for catching moving objects. Add a small delay between the detection and triggering of the flash and you can catch cool things like a light bulb that is is smashing into the ground.

Since I didn’t have an extra laser pointer sitting around I bought this cheap laser card module. It’s very low power so I can run it off a digital output on the Arduino board. Originally I powered the laser directly from Arduino’s +3 volt output, but I found that it was better to run it off a digital pin so that the laser could be turned on/off. Since this laser runs on 3 volts and Arduino outputs 5 volts I used a voltage divider in my circuit to get the needed voltage. To sense the laser I used another voltage divider circuit with a photoresistor. An analog input on the Arduino was used to detect the if the laser was hitting the photoresistor or not.

Sound Sensor

This sensor detects noise. It’s very useful for detecting things like a drop of water splashing, or anything that makes noise. There are lots of places on the web that discuss how to build your own microphone and amplifying circuits. A karioki machine or any other device that has a microphone input and an output line should work. You can pick up a low quality amp and microphone pretty cheaply on ebay or in a retail store. Sometimes you can get them really cheap at a garage sale.

The signal you get from an amplifier is going to be an electrical AC wave representation of the sound going into the microphone. This often means something like a 5 volt 8 kHz wave. The only thing I did was to add a diode to protect the analog input I was using on my Arduino board from the negative portion of this wave. Here are some pictures from my oscilloscope of the wave being generated by the amp. The first one is the full wave of my voice (I was singing “Twinkle Twinkle Little Star”), and the second picture is what it looks like with a diode.

I like the idea that it can help us take the specific moment I want without using multiple shoots at once. Besides that, it also helps me to save lot of time as it is a “one shoot confirm can” way. With an arduino, I can not only get only high speed ones but also slow shutter etc. 

I try to look for a video in youtube and below is the closest one I can find that is related even though it doesn’t use an arduino. As I mention before, with an arduino, it can be program and used in even more ways.


I find this very fascinating as most of the projects I see that have a mouth including mine is just fixed. The arduino projects that I have seen so far, the mouth is just there as a cover for the speaker and stuff to be played. However, this particular project does have a purpose for putting the mouth there and I find it rather important. Not only that, the things used for the mouth is very simple and straight forward. I once thought of doing a upper and lower lips for my project but don’t know how and actually all I need is a servo.


I am quite sure that those who are browsing my blog will know what an arduino is so I will not go and paste the definition from wiki.

The Arduino platform lies somewhere between Technic Lego and the low level geek world of circuit building. It consists of two parts; the hardware and the software, and with these you can build almost anything, from a simple flashing light to a box of tricks that sends you a Twitter message when your houseplants get thirsty.

Our home computers are great at communicating with other computers and (sometimes) with us, but they have no idea what is going on in the world around them. Arduino, on the other hand, is made to be hooked up to sensors which feed it physical information. These can be as simple as pressing a button, or as complex as using ultrasound to detect distance, or in the above example, monitoring the current flowing between two nails in soil: when the soil gets dry, the current drops and the Arduino carries out instructions: In this case it talks to a Zigbee internet-connected radio and posts a Twitter message, but you could just as easily have it talk to a robot which would water the plant for you. So the Arduino is essentially a simple computer with eyes and ears.

Why is it so popular? Because the hardware is cheap, it’s easy to program and there is a huge web community, which means that beginners can find help and download myriad programs for the board. It can basically do every command that you have program into and it is very user friendly. It can match up with a couple of softwares like flash, MAX/MSP etc.


I like the idea of using something safe like water to create objects. If music is added, this will be what I call a musical fountain. Musical fountain that uses laser instead is very dumb. It is amazing how people can programme it so precisely. It is a interesting and new way to show an advertisement. I think it is interactive too as if you hate the ad, all you need to do is to stand under it and spoil the whole ad. There can even be a voice asking you to get lost and stuff if you interrupt the ad
