Woo Hoo E-controller traction control now works

Really cool idea.....but I'm afraid it would be like my 1:1, where the first thing
I do is disable the T/C before putting on my seatbelt.

Just say'n.....

Reactions not quite what they used to be, Rick?

[dr fabio]

They never were :lol: Ive alays relied on better engineered cars, but everyone seems to have caught up and passed me in that aspect as well. Hence the e-controller with T/C.

your own design Rick?

what would I need to make one?

Sorry DM not for general consumption at this stage. Taking it to market is a real consideration at this stage. You could make a JayGee version, its a lot simpler, with no electronic circuits in the design, and the design is on the web. A lot of guys in our club use it.

The T/C circuit design is mine as is the power FET control circuit. I dont use a blast replay like most of the other controllers on the market. The power FET has a lot lower on resistance compared to a relay. 7milli ohms compared to 20-30 milli ohms.

I have looked at the controller on slot forum a number of times with the crazy idea that I have a go at making one

thing is I have a feeling I would end up with a heap of little electronic parts a busted old parma controller and a hole in my wallet

Personally I still like the JayGee more than the JCS. I think its a really easy build.

Look at this link for details of a JayGee build.

I haven't been on the forum in awhile and this is all new to me, and also very interesting. My main pet peeve with slot car racing (that I've been doing for many decades) is the cars are too fast. Unrealistically too fast. Seems odd to me to want cars that are visually to scale, with realistic features and decals, and then race them at hundreds of scale miles per hour when their real 1:1 counterparts race at a fraction of that speed. Having slot cars accelerate at realistic rates, like the way digital model railroad trains do, would make the hobby much more fun for me. I know racers crave speed, and always want more, but speed is relative and competitiveness matters more to me. Doubling lap times while still putting a premium on driver ability would be a welcome change for me. Imagine slot car races with close racing and finishes like full sized car. No one would watch 1:1 scale racing if the margin of victory was measured in laps.

So, can these controllers be used to do this? To have a car take a few seconds to reach top speed at the start of a race or after a pit stop? Also, think about rolling starts (like almost all forms of American racing) and restarts with cars at reasonable speeds and acceleration rates. Or, do any of you folks have any ideas about other ways to have slot cars accelerate and race at realistic speeds?

I had not considered this as an option but yes it could be done. I would have to rejig the T/C values but its possible. You could set the voltage ramp rate and the voltage set point very low.
