At first my project was going to be something very different to this idea, but it said that best ideas comes from the this that you do. I started to do rock climbing a year ago and it's a sport that I love and it. I though about many ways of create something that could reduce the risk in the mountain or to improve the training in a rock Gym.
I did not found a good idea but, during 3d scanning week and later during molding and casting week I experiment with the face of my trainer to create a personalize climb hold and suddenly I thought that it could be interesting to introduce a sensor in every one of them to recognize the times and movements of the climber. This is maybe too much for a final project and I would like to think more about the best way to do something like that so I would focus in a system to count the time to finish a climb path.
It will be a cheap version of the one that is going to be use in the olympics (this year it will be rock climbing for first time) but focused in start to collect data for regular climbing as part of a bigger system not a timer focus in speed race.
There is a professional system which is based on pressure (you can see at the beginning of the video) but I would like to do something that is inside the climb hold so timer starts when the climber touch it.
This project made in 2016 has many paralelism with mine. There is a screen and a capacitor sensor that it would be in mine too. On the other hand I will use 2 capacitor sensor situated in a difference distance one to start the timer and another to stop it.
For the additive and subtractive process it will be necessary:
For the electronics it will be necessary:
All the part can be found or fabricate in the Fab Lab. At this point I'm only worried about the bluetooth system and the batteries.
Everything will be made except the electronic components.
I will use the following processes
I will use the following processes
Well, I have to close this part but this can be a first darft
If everything is finished before the day D it is possible to make some extra improvements
Extra Extra assignment that I won't do: Connect the system to a cellular app.
Is it work? How sensible the capacitator sensor can be? would the poliuretane resin curate affects to the final result? Is it possible to use a bluetooth connection? How much the battery last? Do I need to use wires or think about a small solar panel? How could be improve? Could be connected to a mobile phone and recognize each path?
My idea is to install the system in my rock climb gym so my friends and other climbers could test it and give me new information to improve the result and see how useful can finally be. Maybe the electronics and the programming are not so ambitious but I don't have any background with this and for me it going to be a real challenge. I hope it will be my first step to a bigger and more complex system related with training for climbing training.
The week of machine design I changed my idea for the final project one more time and I had to think again about the Applications and implications of my final project. Which you can see now (16 of June of 2019) here.
Heliotropo is a kinetic structure tha transforms ambient light into movement an reflect. The Object has been designed to interact with another machines transforming the signals read by the sensors into a peaceful movement that becomes more agressive in the darkness. As the light goes out the machine starts to move faster and producing different effects with light.
For the future i would like to implement more motors and movements that will make the piece more complex and accurate too the real proporties of light as we percibe right now. For the moment I only used a phototransistor as light input device. I bought a
There are many references that I can think about, specially for the movement but I can the most direct and important ones are:
a kinetic clock, that rotares with similar structure to the one I have used
I like the idea of free form circuits were board and wire are replaced by rods that connects different elements creating a 3D shape. This way of creating circuit has two advantages for me, firstly it makes possible to hide wires without in plain view. Secondly you have less elements because structure components and electronic connections are the same and thirdly it creates a beautiful mix of elements.
In fabacademy it's mandatory to design and create a board by milling it so I can't use this method for all my circuit (it would be a crazy idea for the final project, anyway) But I want to use it somehow, maybe to connects two boards or to join elements that are far away from each other.
The idea of using structure and rods to create a beautiful circuit without using wires.
An artistic proyect were electronical components are used to create structures.
A lasar cutted piece of stainless steel that can be deformed, as an extra the deformation reflex light in many different directions
I think that I would design most of the system, starting by the structure and the mechanism and finishing with the board. I don't plan to buy anything finished so this is going to be a huge part of my job for the final project.
If I buy something It will be those elements that exist for the industrial manufacturing, such as screws and connections for wiring. I like the idea of use them for a different purpose that the one for what they have been made.
The base structure and the mechanism is made with acrylic 4-5mm (depends on the part), for the vertical structure I used copper rods, all is connected with binding screws. The mirror are made with a PVC mirror (metalon) that can be deformed using heat and Which I cutted with the vynil machine. The rest of the parts (connections between different materials or the stepper to the structure) are 3d printed.
I've bought the copper rods and the Metalon, which was very specific, the rest of the elements can be found at the lab. I will look for them on internet and in specialized hardware stores around Madrid that I know very well from other times and projects.
The total cost was around 110€, but it's that I had to spend more money in the previous prototypes also there are some parts that can't be buy individually. Here is the complete BOMDonwload from here
I thinlk that I will made all of the elements, I really want to be my final project to be particular and special in every way and component. Also, there is nothing so complex to justify in front of my evaluators that I bought it.
Many. Enough for me to want to improve the object, upgrade some solutions and try some alternatives.
I hope better results in the mechanics than in the electronics, but I hope to do a nice job in both of them. I would like to value the aesthetics and the details. I don't want to do something that works, I want to do something that works well and it's well finished. Not a "chapuza" a spanish way to say that you solve it but without taking care of details to do a good job.
