Very First Real Test
Finally, on Sunday June 12, 2011, the Tilto had its first street unexpectedlysurprisingly good, that after so much effort gave me lots of happiness.
This was only the first test of Tilto and there is still too much to improve, but the idea I thought over a year ago is now working.
Mounting the Beast
When the power drivers were tested ("almost" without producing magic smoke during the tests), I went to buy the hardware.
I worked a little in the workshop of my friend Nicolás and a little more in my apartment, and before long I built a simple structure and started the first Tilto's tests:
At this point I faced the most difficult problem: The electric motors (donated by my new friend Gustavo) are previously owned and a little worn, and have too much backlash in the gears of the gear boxes. This produces a dead zone where the system has no control and provokes strong shocks that destabilize the entire unit.
I spent an entire week thinking and testing mechanical solutions, until one morning I woke up with a simple software based solution.
It worked pretty well, and I finally mounted the Tilto beast!
Power Drivers
Happy with the performance of the "brain" I went to the design and construction of the motor driver modules.
The design is made from scratch, using components that could be available in my city (Buenos Aires , Argentina
The result were two switching circuits, in two homemade boards full of MOSFET power transistors, capable of handling nearly 10 times the current actually needed.
