You already wasted your money on the attorney. Get rid of he or she immediately. Unless they can prove that the machine was improperly calibrated there's no reason for an attorney. There's virtually nothing that can be done. My suggestion to you is to take your lumps and plead no contest.
Sorry, but this isn’t true at all. A good attorney can make a huge difference with the outcome of the case. In my wife’s practice, she had good relationships with many members of the court staff (prosecutors, judges, etc), and she often got sentences reduced because of those positive relationships. That (plus knowledge of the law) is what you’re paying for.
Going into a situation like this with no legal counsel is the worst thing you can do. Saying “there’s virtually nothing that can be done” is simply wrong.
