Pinging AstroSlot..................

Greetings- I've PM'd you a couple of times and sent you an email via SCI's email system, so I don't really know if you've received it. In any case please contact me in regards to your DIY box, I have a question or two. Thanks very much, Paul

RE: Box

One question

And let me qualify that I am no electronics guy, nut I have built a few drivers stations/control boxes., SO . . .

My question regards the use of Potentiometers! In the past I have seen people argue that these don't work (Although I don't recall the reasoning, it made sense at the time)?
http://www.slotcarillustrated.com/po...ivers+stations Post #2 is an example.

That's why most circuits I have seen use a Diode selector setup or and Integrated circuit set up!?

I like how you've intergrated all the lanes into one box; for my purposes I am working on one circuit for each station with it's own transformer to avoid previously mentioned problems with power lane spikes, etc.

The use of Potensiometers depends on the amperge you put through it.
For standard motors in 1:43 you might gt away with it. But for hot motors you might draw too much cur4ent and will wear them out quickly.

Comparr a regulat pot. with the var. resistor in your throttle.

YMMV.

Do we have any reccomended power rating of these components for 1:32 scale?

For high current applications you could substitute rheostats for potentiometers, those are wound on a ceramic core and have a copper/carbon wiper, so they can handle more power. If you want individual variable voltage for each lane cheap voltage regulator modules are available.
