    I’ve started looking into the idea of changing the transistor in the RX stage of the car’s pcb with one that has a higher beta value (thanks b007a). We’ll see what happens.

    One other thing I have noticed is that the straighter the car’s antenna (ie: nice and perpendicular to the ground) the better the distance achievable.

    Yeah, there’s a few things on the tool that I don’t know what they do.

    I know the following functions:

    1) Shell removal via front hook.
    2) Heatsink removal via indented tab.
    3) Motor pinon removal via slide.

    Mut, this is the exact same problem I have, I’m still trying to find a solution. We’re not all as precise at Micro_amps! :p

    lol, and you had to edit that one!

    I’m a Network Administrator at a major manufacturing company.

    I did an EE degree at Monash but so far the only real application has been these cars, and that’s incredibly sad……

    trash, what do they need to run? V? I? What’s their impedance? Do you have any datasheets?

    One thing I found was that when I dremeled down the front wheel wells to add space for my full size wheels the light started coming out of the plastic there. I recoated the edge of the wheel wells and all is fine now.

    Dave, i think the DIP switches are the same thing you are referring to. You might be able to stack two in the same area but I dunno.

    Most of it is to do with the paint I use, a thick black gloss paint applied liberaly….

    The circuit is pretty much this:
    dcdcconv.jpg

    There’s also a 330Ohm resistor in series with the LED’s. The LED’s are wired in parallel.

    The dcdc convertor is from http://www.onsemi.com . It’s the NCP1402 model, 5V version. I got the pcb design in CircuitMaker 2000 format. I’ll post it tonight.

    Parts List:

    Cin=10uF
    Cout=47uF
    Diode=schottky type (Low Vf)
    L1=47uH
    U1=NCP1402 (5V)

    great job ph2t. What exactly does it do again? How do you switch the lights on and off? I’m confused. Sounds good though.

    It turns the battery off, removes it from the circuit. Like a normal on/off switch. Since my lights/kitt lights are connected straight to the car’s PCB, it turns them off as well.

    Yeah, you can’t get them in single form, from the “research” I’ve done anyway.

    The resistance of the wire is fine. It’s gauge is ?? (I’ll find out tonight), I got it from Jaycar, there’s no problem with using it.

    Sounds good fellas. Prez has a good point about “normalising” the mods somehow.

    Maybe include general requirments, eg:

    Soldering required
    Cutting/grinding required
    paints required

    and then skill level

    Expert
    Advances
    Intermediate
    Beginner

    and so on….

    Then check the seating of the magnet in the steering assembly, the glue that is used from the factory is quite weak and the magnet can come loose after a while.

    Also, have you stuffed around with the steering assembly? I noticed that when I put the magnet back in the steering was crap! I had put the magnet in the wrong way. So try removing the magnet and flipping it over and put the assembly back to together. This is how I found that out!

    Strange, you have a dual cell yet the steering won’t turn. Are you sure the steering is actually OK? How heavy/large are your wheels?
