Have you verified that you're getting 5v at the wheel encoder? |

Get your x wires shorted somewhere, and you'll get the jittery cursor I had above. Get the +5/gnd backwards, and you'll get nothing at all, except possibly a dead opto board. (although I've done it more than once, and never smoked one yet) re: your reluctance to pull the panel- Do you mean you'll have to pull it in order to hook up the mousehack permanently? Can you even hook it up on a temporary basis? That could help you track down the problem- if it works with the mousehack, then you know it's the wiring or the MiniPac. |

BUT, if the mouse hack works and we can't discover what the problem is, guess I'll be pulling off the whole thing *again!* :hissy: |

Well, I tried both opti boards, both from eBay, both from different sellers. Reflowed all the joints. Boards each getting 5v when hitting the ground and 5v pin AND 5v at the input pins for X1 and X2 when hitting either of those pins and the ground, with the optis both uncovered and covered - IIRC, from days gone by, there should be voltage differences when the optos are blocked and when clear (since that's how they work). I'm finding it hard to believe BOTH opto boards are shot :( I DID clean the inside of the opti sensor (the part where the wheel would go) - they were caked with crud. Just used napkin and spit, tho. Anyone know if any microfine scratches on those would render them useless? Perhaps I could remove the dark covering on them or are they needed to let the LEDs work corrrectly. This sucks it hard and long, Trebeck. :P |
