 | | GBC- Magnetic Ball Separator —Kevin McClure
|
| | | I just finished my new module, a magnetic ball seperator. There was a discussion a while back about building a module that could detect a single 'tracerball' in the ball flow. The red and blue basketballs were ruled out, because the light sensor (...) (17 years ago, 19-Jan-07, to lugnet.announce.moc)

| | | | | (...) Excellent! That looks like a really great addition to any GBC: for one thing, I've often wondered how long it takes to complete "one lap", and you really need a long average (as some modules recycle balls, etc.) I hope it's OK with you if I (...)

I think it's a magnetic "ball-separator" - not a "magnetic-ball" separator. :-) I have a bunch of steel ball-bearings in my Lego storage system - so they must be used in one set or another - I have no idea which ones though. There are also (...) (17 years ago, 19-Jan-07, to lugnet.robotics)

I was as lazy as you at the fore, thinking "why not mention which set in the initial post?", so I had to look it up myself. A shame that set seems to have been released for such (...)

Peeron has been loading slow for me as well, and with that darn (...) (17 years ago, 21-Jan-07, to lugnet.robotics, FTX)

You could increase the slope to help with this also. :-) If the ball is magnetic (...) (17 years ago, 20-Jan-07, to lugnet.robotics)
