I’ve been using this product for development of my interface. Here some things I’ve learnt about it

Making a velocity sensitive controller

The contact of this product works using conductive silicone. The conductive silicone has the property of changing the resistance when it is under pressure. I measured the range to be between 2 and 0.008 K.ohm. This was tested using the same pcb etch that is used in the original sparkfun board, but in a custom built board that is using tin plated contacts.

The 2 K.ohm resistance happens when just one side is slightly touching the contacts. The 0.008 K.ohms happens when the button is being pressed firmly, but within a normal range. Anyways I think that the relation between resistance and pressure slope will get weaker and weaker. According to my understading, lower resistance values will result in a larger voltage variation.

I have used this effect. In that use case, I was measuring each button behind a multiplexor, and I applied a pull-down resistor of 470 ohms in the common pin. I believe that any pull-down resistor between 1.8 and 400 ohms will result in a pressure sensitive matrix, assuming that the matrix output is collected by an analog pin, of course. I don’t recommend using this setup if you expect to use a digital pin, because slight pressures could result in button detection, leading to bounces and a poor overall interaction.

Importing sparkfun’s eagle pads to Kicad

Using a text editor it is possible to import sparkfun’s routes. This process will be explained at changing the layer of routes on kicad.

If the entity or entities of artificial intelligence were to become the sustainer of human life, and also our best friends, how will we, humans find the meaning of being within such a context? We need to provide the new species with the ability to provide humans with a meaningful existence as well.

Since very long ago, humans have either dreamt of having everything done without having to work, or different people at certain point have just taken care of optimizing very particular tasks, one after another. Either case, it seems to be part of the whole world culture that we move towards automatization of our work, replacing human labour by machine labour. The assumption is that it allows humans to partake in activities that make more sense, that are more important, and improve the quality of life for less work. There is a threshold on the progress of automatization of work: thinking, seems to be the ultimate leap where human work will be finally replaced. But once we make machines think like us, effective brain-androids (whose thoughts are shaped like ours) will only our work be replaced, or does it also compromise our identities, and the identity of a whole humanity? I will be writing some of what I have learned and thought in the last couple of years, while living in different places of the world and getting different influences.
