...in fact, when in regular use, the halogen lamps are just lit a little bit or not at all...

So no sensefull lighting stuff...

Fine. Correct.
I would call it a poor man's WAM module for a two liner


In fact I had two chips left over and currently there is no money in the budget for two additional Lane Brains.

So I thought about chipping the rails, but the chips aren't secured against a short on the motor side....

I tried to find a simple layout for an electronic fuse but things were too complicated to implementfor me, as I'm not much into electronics...

I came to the idea in putting a 12V / 20W halogen spot light between each chip and the track. If there is a short, this will limit current to about 2 Amps, so that should do.

This approach has several drawbacks (That's what I think, some guessing involved):
  • The more amps the motor draws, the more amps go through the spot light. So car should be slower than without. Especially acceleration will suffer.
  • Breaks will become softer.
  • I do not really know, if this kind of currency limitation is good enough.
  • Sure, there will be no warranty, as the chip never was intended to be used like this. So, if the chip is destroyed, this is my risk.
  • more?

However, I do not mind for home use and I take the risk.

What I'd like to ask: Does anybody know about electronic fuses that can be used to protect such a chip. Would be happy to put one in.

So does it work?

I tried chipping a lane at my local club track and cooked 2 chips. I connected it the same way only without any protection.

It works on my home track for two days now. Voltage is about 12 - 16 V.

During beta testing, it worked - without any protection - for more than a year until the chips were burnt.
