Way small computing.

Posted in Hardware at 12:22 pm by Tessa

Today, our Gumstix arrived. This is a very very small computer which weighs only 9 grams. We are going to use it on board to drive the motors and maybe later even to do all the processing and make Zeppy really autonomous! Our first challenge with the Gumstix was to activate the Bluetooth, so that we could access our small computer. Some wires had to be soldered to the little machine, which was very exciting, fortunately the third time they were on the right pins! Now that we could access the Gumstix, we could try to drive some motors with them, but unfortunately it was impossible to do this directly with the Gumstix, which we had expected. The outputs could not provide our motors with enough power, therefore we have to insert motor drivers into the circuit.
