Final Year Studio - Development - Multiple Stepper Control



While both the on screen part of my project and installation space is all setup I have simply ran out of time on the development for my analogue display board. Above shows each stepper motor animating, one after another and moving to a random position as each Datamotive starts to arrive. Controlled by my time function in the Processing code, the whole screen starts to animate when its arrival time falls to 60 seconds or under. Controlled by a total of 6 breadboards, 2 Arduino boards and 48 relay switches I managed to wire up all the motors that would be used to show the text of the domain address.

Each stepper motor is controlled by a group of Arduino output pins and 4 general relay switches that fire each stepper motor's 4 individual relay switches and each motor simply requires the turn on and off of their ground to animate. In theory the next step would be to build in some kind of reset mechanism so that the stepper motor can keep track of its own angle. This could then be used in conjunction with knowing the step count of each character to show specific letters and numbers. Also the stepper motors that control the arrival time would have to be wired up to a separate breadboard and programmed with a slightly slower delay for a slower more accurate animation that would countdown properly.

Final Year Studio - Development - Exhibition Environment

With the end of my project looming I decided to visit the space that will be used for the end of year exhibition. After consulting with Jen it became apparent that the 'ideal' design for my installation would have to be slightly comprised to fit in with the space. I have decided to create the illusion of a train station as best I can my using a PC situated on a desk along with my analogue public display board. The space will be also enhanced by using a clock, arrival time board and station sign, as well as speakers for ambient sounding. Once setup I will then evaluate whether or not the space can cater for a bench, but this I must stress will be decided upon nearer to the time.

Final Year Studio - Development - Multiple Stepper Output



After getting one stepper motor to work the next step wire up multiple stepper motors. This involved using four control relay switches, plus four motor relay switches and one ground relay switch for each motor. The motors were alternatively driven and were animated by simply turning their ground connection 'on' and 'off.' This resulted in a very complicated circuit, that in theory when adapted will allow me to directly control each motor and dictate which letter will be shown.

Final Year Studio - Development - Review #4

Another good review and I felt that I am getting to narrow down my project very well. All the theory, research and development seems to be coming together. My only problem is that it is looking like I will not finish my analogue screen on time due to the problems I have had previously with the servo motors. Regardless of this I have constructed the actual housing for the screen and it was a useful tool when explaining my idea, as well as in the conclusion of my Special Study which compliments all the trials and tribulations of developing a analogue mechanical public display screen.

The aim now is to finish the main digital bit of the project, and analogue screen if I get time, as well as experimenting with different digital visual aesthetics, just to understand the alternatives of offer.

Final Year Studio - Development - Initial Stepper Motor Test



After a while struggling with servo motors it has been decided to swap and change my design so that I can use stepper motors instead. Initial tests have proven very encouraging and show that the stepper motors are both smooth and reliable due to lack of physically moving parts inside. Due to the fact that the main area of development for my project is on the digital monitor, it is now looking as though I will not be able to finish the analogue style public display screen in time for the end of the year. This will not stop me trying in my spare time and constructing the housing for the screen, because all the trials and tribulations of development make up the body of my Special Study. So it will be useful to have the screen constructed and a stepper motor working for my conclusion where I can talk about possible implementation.

Final Year Studio - Development - Arrival/Departure Time Board Design


arrival board, originally uploaded by Jimbo (Alan James Wellock).

Using the above images taken from Bradford Interchange's train station as inspiration I will create an arrival timetable board for my Datamotive idea. Displaying search terms that represent key words that I have come across during the development of my idea, it will show the arrival times of each Datamotive, dependent on the finalised formula for optimum screen representation. This will work as an extra stimulus for widening the associative bandwidth of the installation environment as well as a 'witty' hint for users to find out more about my project.

Final Year Studio - Development - Review #3

Just a quick report on review #3 of my studio project, Datamotives. I felt it went really well and I think I have concentrated what I was presenting more, resulting in less time spent explaining the idea and more time spent showing the various experiments I have done and first person research. The only thing to do now is make sure my elevator pitch isn't misunderstood and continue making my project!!!

Final Year Studio - Development - Servo SUPER DISASTER!!!



Above is the final experiment I did to try and solve the 'wobbly' servo problem. In the end incrementing the servo arm, changing to Oasis foam for the screen and programming the servo by not using the code library still did not solve the problem. A possible factor is that the small servos simply don't react well to being controlled from a computer, chipping all the gears inside them. A possible solution is use a stepper motor instead that has only one gear and is animated using magnets, resulting in very little wear and tear inside the motor itself, hopefully eradicating any kind of developing wobble. The only problem with a stepper motor is that it cannot keep track of what angle it is at, this then means I would have to use some kind of marker such as a light resister and laser to tell the stepper to reset its angle to 0 for further instructions.

Final Year Studio - Research - Domain Name Facts

As my digital screen development for my idea progresses it is becoming apparent that I will have to decide the number of characters going to be shown on my public display mechanical screen. Although according to the Length Distribution graph located on the link below states that most domain names (2006) are 11 characters long (not including the suffix (.com etc.)), I decided to go with a 10 character long screen (including suffix) so that I can then save two servo or stepper motors for the time of arrival of each URL. In the long run this will not effect the installation, because one of the main points of using two different mediums is to highlight the limitations of each, in this case the limit of not being able to vary in display depending on character length.

Final Year Studio - Research - Grand Central Stands Still



While researching the theme of train stations and time I came across the above video created by improveverywhere.com, which involved 200 'Improv Everywhere Agents' standing still at Grand Central Station, New York. Train users are baffled and amused as it takes a while for each user to notice that some people are not moving in conjunction with the overall crowd.

Final Year Studio - Development - Relay Switch


relay 400, originally uploaded by Jimbo (Alan James Wellock).





Above is what I hope will be the component that will solve my servo wobbling problem. The image is of a relay switch that only powers the servo motor when the servo arm isn't at the angle it is supposed to be at. This then means that if the servo arm starts wobbling it stops, the instant it hits the correct angle. This in conjunction with slowly incrementing the angle of the arm and creating the screen out of Oasis foam, often used in flower arranging, has seemed to have also solved the problem and at the moment a single servo motor is working fine. Hopefully it will be a simple step to add more servo motors onto the single relay switch so it can turn all of them off as soon as they all reach their specific angles. Fingers crossed!

Final Year Studio - Development - Large Servo Test





With the small servos struggling to cope with the momentum and weight of the acrylic screens I thought it may be a good idea to test the torque on some large servo motors. As you can see above they operate in exactly the same way as the smaller ones but without attaching anything to them they already felt slightly loose in inside. So to finally test to see if they would work with out wobbling I attached a screen to the servo arm and tested a single servo unit. Unfortunately the weight was still too much, and still vibrating occured.

In testing this though I came up with a possible solution. My theory is that if I can get a light enough semi-circle screen to attach to the servo arm and use a two way switch to turn the servo motor off once it arrives at its specified angle, I may be able to salvage a workable screen. Possible materials to experiment with for the servo screen could by polystyrene or the 'Oasis' blocks used by florists in flower arranging. Both highly durable very light materials that wouldn't put too much strain on the servo motor and its arm.

Final Year Studio - Research - Flip-dot Display System

I also emailed First buses to ask what they do with their flip-dot display screens once they replace them with LED equivalents. Unfortunately I did not get any response from them and I am still waiting.

Final Year Studio - Research - Split-Flap Display


screen email, originally uploaded by Jimbo (Alan James Wellock).

Although at the moment I am using servos motors to design my analogue screen, I am still trying to source a split-flap display to understand their availability. As I mentioned below Thomson & Craighead's Beacon project uses this display system so I emailed them, asking where they got theirs from. Unfortunately it was bespoke and made by Solaris themselves at great expense, it is also important to note that Thomson says the technology is now discontinued.
