Electronic team working hard on the PCBs.

Electronic team working hard on the PCBs. Since our courses finished we are working full time on the ISAAC project.

I finished the Schematic design for digital part of the  Infra-Red circuit and now I am working on layout of the Power_Top.

Here is the Infra-Red schematic or IR_Top. It contains of different circuits; FPGA, memory, regulator, clock oscillator, reset and connectors.

In the next picture you can see the Power_Top layout. It is not done yet but I hope to finish it during this weekend.  This layout required more work in compare with a normal design. We had some changes of the connector’s placement and the board size.

 I had to start from the beginning for two times. The reason was loading error, when I tried to open the saved design. I learned to be patient with this tool and every time drawing became faster than before.Image

I think layout design is very similar to oil painting. As much as you are handy, your design will be beautiful. But I now this is the not! 🙂

When engineering and art meet

Some time ago we show you in here our work on the PCBs, and today, I want to bring it up again.

Past week the electronics team had been working in finishing most of the schematics and the layouts of all our units, mainly the RxSU. More in detail, I have been spending my time on the RMU PCB. I know that experts can complain and some improvements can be done, but I think that it is good enough for being my first one. It also may not look really nice, I’m not an artist! However, I like it, it’s my little baby. But by finishing it we are not done, a lot of work is still remaining, and tomorrow a new day will come, where we will be working on other PCBs and/or firmware while our friends in the mechanical team play with heavy machinery making holes, sanding or cutting metals.

Finally, after a long path working on ‘paper’ we are getting close to have the real stuff to play with. The real stuff that we aim to launch into the sky.

And as if a proud father I were, here is a photo of my baby.RMU PCB

Computer Simulation

Today, let me digress for a while with regards to the post. But as a matter of fact, what I want to present is a little related to ISAAC, as well as flight dynamics.So what I am going to talk about? Er, it is computer simulation.

As you might know, in order to study the science, and get to know the real world around us, we commonly need to do some experiments. When it comes to an experiment, you may well think of scientists in white coats working away in a laboratory. Well, in fact, computer simulation is also belong to one type of experiments, which sometimes is called “computer experiment”.

Here, a model is implemented on a computer leading to a dynamic demonstration. Further
interventions can then be programmed to explore how they affect the scenario. In some sense, this is clearly more about modelling than experimenting, because the control and intervention is performed on a representation, not the “real stuff” used in field or laboratory experiments. Anyway, to run an experiment on a computer is thus similar to experiment with a laboratory animal: both are used to experiment, in order to learn about a substantially different target.

In terms of the definition of an experiment, which is a controlled observation in which the observer manipulates the variables that are believed to influence the outcome, therefore, computer simulation is a kind of experiments.
