Members present: Mike H, Rika L, Crystal V, Kristina K, Victor, Karen
Tasks Completed:
- tested Box-O-Mice... threw out bad mice.
- Found encoder and added wires to mouse. The Black and Yellow wires on the mouse are giving signals. The other wire leads are not connected right but should be the game signal wires (if we didn't burn out that encoder)
- Inventor brackets added.
Tasks In Progress:
- Continue on making mouse work. Since we now know what encoder leads to connect to we can start making final mouse decisions.
- Place battery box on robot in inventor.
Tasks to Complete:
- Measure wire for placement in inventor.
- More mouse fun.
Mentor notes on Mice from Karen:
Last night, Rika, Michael, Kristina, Victor and myself did some mice investigations.
It was a slow start due to an epic search for a good oscilloscope probe, but we prevailed and were able to wire up one white dell ps 2 mouse. The good probe is labeled 'good'. Said mouse turned out to be a dude ('doh).
We then wired up another supposively working dell ps2 mouse - after our earlier epic fail. Since we were suddenly very serious about seeing some kind of success, we decided to leave the ps2 connector on the mouse, and hook it directly to the old win98 pc.
- The first detector wired - dud ('doh) the mouse did not register any horizontal movement. (This may be due to excessive man- handling by mentors and students)
- The second detector wired - Success! We saw vertical movement and two channels of slightly phase varying pulses, similar to what we have on the one working mouse
- This mouse is now on one of the electrical shelves. The good phases are on the yellow and black wires. The orange wire is +5
- We should be able to carefully wire up another mouse in the same manner and see good data for both the X & Y axis.
- We cut the PS2 connector off of the first mouse sacrificed for the cause. The resulting mouse cable has very nice higher gauge wire. This wire is very good for soldering to the through-hole legs on the back of the mouse board.
- The remaining mice have been categorized as 'good' or 'untested' and are in a box in the pink cabinet. We should be able to modify one of the 'good' mice to create a useable back-up.
- As mouse manipulation has proved a little tricky - I would recommend having 3-5 spares ready to go. It may take a while to modify mice, and I don't think this is something we want to do under pressure.
