WORK WITH VYNIL CUTTER
I worked on the vynili cutter to make the traces that will short the different parts of the animals.

The corners are smooth out to simplify the cut, the machine set-up was speed 1mm/sec and force from 80 up to 120.

WORK WITH LASER CUTTER
The debugging process forced me to use also the laser cutter and actually I'm glad it happened. I found out that the oak wood filters the blue light, I didn't have chance to see it fron the inside of the central body. To fix this lack I decided to cut a grid in correspondence to the led.

To properly allign the laser to the shape of the wood I followed the steps:
- put the wood in the laser cut and make the autofocus
- remove the wood from the laser
- place a sucrificial panel
- made the focusing by hand, in this way I could note how much the z calibration changed. In my case 15,7mm
- engrave the body profile on the sucrificial layer
- move the laser back to the z calibration for the wood
- place the wood centered in the engraved profile
- and send the job.

I used for the sucrificial layer: power 100, speed 5, 750 ppi and for the oak wood: power 100, speed 10, ppi 750.

ASSEMBLY and DEBUGGING
I had to add some magnets and sand the led board corners.

CODE
The code can be much more improved, I had 1day and half to write it. As soon as I will fix it I will also aupdate it.
The explanation of the functions and the code are the comments in the code.

MISSING

- I couldn't make any molded and casted parts. It was part of my programm to change different materials.

- In the code I have to implement the sound to ricognise the different animals. I'm not going to add it now. I will do it in the next prototype when I will implement SD card-read.

INVENTION, INTELLECTUAL PROPERTY AND INCOME
The actual prototype needs several improvements so, first of all, I would try to create the possibility for myself to work ahead with the project. To do that I'd search support through crowdfunding, I'd search someone interested in my idea and who could invests on it. I think that for this porpouse equity crowdfunding sistem of Symbid is the good choise.

"Symbid is about investing safely in new, promising, fast-growing businesses. Before a company is traded on the stock market, anyone can acquire an equity interest and profit by having the foresight to anticipate the company's growth.
[...]
How does it work? For each business that acquires new investors via Symbid, Symbid sets up an investors' cooperative.
[...]
The investors all become members in this investors' cooperative and it is the cooperative which is ultimately the shareholder in the business. Complicated? Not at all. Is there any increased risk due to the indirect ownership and control? Absolutely not. Of course, the universal entrepreneurial risk still remains, as in all equity investment: if a business cannot fulfill its obligations, it goes bankrupt and the investors lose their invested money."

It would permit the financial conditions not to sell the product but to develop it and reach the goal to have a product that can be qualified and read to turn in a business. In the meanwhile I would also look for someone with commercial and marketing expirience that could manage that part of big project.
