Collecting the pieces

It was finally time to collect everything so that everything would all come together as the final product.

Starting out we tried setting up all the six stipulates with LEDs to make sure everything worked smoothly and as it should. This was quite a challenge since the wirering for just one RGB LED strip needed 4 pins including the three colors connected to a transistor. Perhaps overly complicated but the only way we could get all of our LED strips to function as we wanted.

Making the lifting mechanism 2.1

After our components arrived, we were ready to build our scissor lift.

The first thing we needed to figure out was how to attach the metal parts on the plastic screws, that are the moving parts of the motors. We did this by making a two custom made steel rings with internal threads, that could be mounted to the plastic screws with bolts. The two rings were welded together to secure a stabil structure.

The scissor lift contains both self processed and standard component

Code and NodeRed

Our nodeRED flow. 

First of all we decided to add a personalization to the product which would further add a connectivity dimension for our project. This including an rfid scanner from which you can scan your mobile phone, and the device will remember your previous settings from last time the user worked out on the bench. This is made possible from nodeRed and furthermore we have create an ‘app’ that the user can control the device from. This would mean that the user can also adjust the setting directly from their phone (the app). This would take away unnecessary time to adjust settings and give more time for the user to actually work out.  Continue reading “Code and NodeRed”

Making the lifting mechanism part 2

As mentioned in the previous post, one of the supporting structures malfunctioned because of a crooked welding. This was a new obstacle we had to overcome, but luckily the team made a great discovery, when they were looking for motors!

This motor was taken from a trashed table with a build in lifting mechanism – could it be more perfect? Of course it could… If we wanted to use the motors, we would have to rethink the use of them, because of among others stability issues, that could only be solved using part from the table, we could not recover.

After a long discussion about different solutions and possibilities, we decided to go with the motors, but build a scissor lift structure to support the top and lift the bench.

Step plate prototyping

Yesterday we made the second prototype of the step plate.

On out last prototype we stated that the frame of the step plate was too wide, but since we also need LED light inside the frame we actually decided to keep the frame size and make a slot in the middle to the LED strip.

Therefore we started drawing the parts inorder to make a CAD model and explore both some colours.

Some of the parts turned out to be overkill when we made the prototype.

First feedback on the final project

After our presentation of our new concept last week we got one major critique which we needed to figure our way around. The issue was that our concept did not include any mechanic aspects.

The way we approached this, was by listing all the potentail mechanical movements we could incorporate into our idea. See list on picture below.

Smart Climate

Concept

The average person spends more than half of his day indoors. Therefore a good indoor climate is essential. Indoor climate affects health issues such as allergies, concentration problems and tiredness. A good and stable indoor climate gives an overall feeling of wellbeing.

To insure this we have developed a concept being a user interactive device that secures a stable and healthy indoor climate by responding to humidity, temperature and pollution inside and outside homes. The device is connected to a window that opens if needed in order to obtain a better indoor climate for general health.
