    Edd, are you talking about making the small boxes sort of like the ones Ken made with the pushbutton on the side. I really want the kids to push the button with their fingertips or palm because in the competition they have to leave their hands on the table until time to push the button. I want...

    Do you think I could use a 1" high box or would that be too close to the button prongs? Looking at price and size the 3" X 2" X 1.1" or the 4" X 3" X 1.6" are within size range. The 4 X 3 is bigger than I need but I do like 1.6".

    These are the buttons I bought from Radio Shack months ago when I first started thinking about making a system. So either I need a box to fit the buttons or get new buttons.

    ChosunOne, I was practicing my limited electrical skills today with the parts you sent. The buzzers are great. I think the push buttons I bought will work fine. I wired the a button to trigger a buzzer and LED. I know it is simple to do but was fun to see it work. I still need to get small...

    I have not given up on this. I have been sick for the last week and state testing in school is keeping me busy. These last few weeks of school are insanity busy.

    Time passes quickly for me too but I think it is more of memory loss. LOL Why did you connect the handheld boxes into another box then to the main controller? Why not just connect them to the main box? Is the red handheld button your reset and lock out buttons. I don't know if I like the...

    Ken, That's a cool system. What size boxes did you use? Do you have a photo of the inside of the main box? Is that speaker wire?

    Bonjour I have studied and found more questions than answers. I emailed our local community college electronic department and while the person was very nice and offered their students could make it project next spring, that does not help me now. She also said it may end up costing me a couple...

    wow, I have a lot of learning to do to understand what you nice people are talking about. I have been watching videos on reading schematics and how to transfer all that to a breadboard. I would like to have the buttons and lights in project boxes and enough wire (7 feet or so) from the reset...

    I was thinking of going to our community college to look for "electronic nerd students" and I do say that with affection. I am a tree hugger at heart. It would be easier, but that would take the fun/ frustration out of doing it myself. What is the power source for your design?

    I am a teacher and science bowl coach for an elementary school. It was my first year as coach and found out the students really need to practice the mechanics of the game. We need an 8 playerlock-out buzzer system. The systems we could buy are too expensive and I do love making things...
