Narrative #13 3/21/03
I worked on the applied piece. Palance gave me the new stamp and helped me with the circuitry the makes the output from the receivers readable. Early in the week
I could see just what the finished product would act like because I realized that I could hardwire the drive motors on. I saw it move forward, backward, and turn.
The trick will be to make this all happen by remote.
Aside from this I bought three more relays, two for the winch motor and one for the electro-magnet. I wired those into the breadboard. Also. My dad worked on a part to attach the winch motor to the spool and then the deck.
Wednesday I stayed after school with Palance and we got the “fried” stamp board working again, it was only a capacitor. Now there is a complete working BASIC stamp. The next step it took was checking the receivers again, confirming my suspicions that they were both fried. In finding this out for sure I took a trip down to Radio Shack and bought two mini r/c cars, which I found out that the Radio Shack brand are called “Zip Zaps.”
I stayed after school Thursday and worked with Palance to get the receiver signals to something that the stamp can read. We got that working although it was
through working with inverse logic, but that really doesn’t matter.
Friday I wired one of these with the ribbon cable that was attached to the old receiver. I got that receiver working and controlling the forward/back motion of the robot. Not the left/right, but that shouldn’t be too far off.
