If anyone read my thread about inverting a coin switch signal, you'll know that I've been trying to get an AE2411 dbv to work with a model H Skeeball.
The coin switch has a +5 wire and a Ground wire. When the switch closes, the +5 is pulled low to zero and the game starts and releases the balls.
Anyway, after a bunch of testing today, I discovered that when a dollar is put in, the dbv is only pulling the +5 down to around +3.2. Skeeball recommended putting a high value cap across the two wires to try to hold it low longer, but that doesn't help it get lower.
So - how do I get it lower? Could I put a resistor in series with the +5 line to drop it to +2.5 so that the dbv will drop it down closer to zero? I also don't know the current (nor the way to look for it) in order to calculate what resistor value/wattage to use.
Anyone have any bright ideas that are simple and possible in 2 days using Fry's or Radio Shack parts?
