timeTable

I’m fed up with the transportation service of my city, it’s slow and it gives no clue about what bus to catch when you need to go somewhere.

I’m planning to do a web application to use with it and I’m developing a website in Django/Python to implement the timetable with a search for routes.

The final goal will be to put a “I’m here” button which would tell the nearest stop and tell you the next useful bus to catch.

After learning a bit of Python to work with the Tumblr API I’ve noticed that it’s a quite nice web oriented language to use, so I choose it in combination with the Django project and programming dynamic web pages it’s not as bad as I remembered from high school. 🙂

solarPower changes

Basically I’m switching to gEDA, another open source EDA tool, I’m much more used to it!

I have planned to use a small 8 pin Attiny85 microcontroller, wich I’m going to buy from mouser, with a sharp memory display or a normal lcd as interface. The sharp one has the advantage that it’s very low power and with a very good readibility, the other one it’s much more easier to interface, a typical 4/8 bits parallel LCD.

The attiny85 has just 8 pins, so I planned to use a 74HC595 shift register to interface the display with a 4 bit configuration and switch the charging of the battery off when needed.
