Light system options?
Maybe i just couldn't find it but, i didn't see a light kit thread...
i am overhauling another Wedico loader for someone and he would like a light kit installed so that it has brake lights and back up lights. We tried the rc4wd/smart light kit and the headlights turn off when you back up and the tail lights go out when you forward...i.e. not good.. Any ideas for a nice light system? |
Re: Light system options?
I had emailed r/c lites once and they told me that they could configure one of their kits for a semi,so I would think that they could configure one for the loader. Sorry I done have a link but hope the info helps

Re: Light system options?
Check CTI modules. AFV carries them.

Re: Light system options?
Ihave some experience wit the cti devices as they are in my excavator(lights) and in one of my trucks(controlling lights and relay for a pump motor).
They can have up to four outputs, each toggled on/off by a single channel. Cheers, AP |

Re: Light system options?
Looking at all of these lighting systems i am surprised at how hard it is to find these options.
1)Headlights stay on 2)Taillights dim and bright when brake applied and turn off when reversing. 3) reverse light that comes on when backing up i will call rc-lights and see if this unit does what we need for a loader: http://www.rc-lights.com/products/RCL5053.html |
Re: Light system options?
I changed the original wedico electronic to servonaut.
S20 with rear and brake lights in conjunction with a ml4 do the job now :-) Br, Tom |
Re: Light system options?
Have a look at the HeyOk lighting controllers that RC4WD are now selling.
http://store.rc4wd.com/Brake-Reverse...er_p_3131.html This particular one has several outputs, you can have an always on for headlights, a switched output for driving lights that comes on with forward throttle, the tail lights are dim while driving and are always bright for brake lights with the throttle in the neutral position, and with reverse throttle the reverse lights come on. You could always just ditch the switched front output and you have always on headlights and tails, with switched brake and reverse. They've recently started selling their products and they have a few different options for lighting modules. |

Re: Light system options?
Hi,
I used this one on one of my builds (sorry.. the page is in German..). It's tiny, but works great: brake/reverse-switch They have a new model that includes a beeper now.. Beeper thingie Here's the vid of it in my Jero: http://i948.photobucket.com/albums/a...Test_final.jpg (I used the reverse module in combination with this module here: turn signals and lights ..this one switches turn signals and lights). Cheers Pip |

For the stick movements: do you refer to the valve movements ? Br, Tom |

i like to have all of the engine rev anytime work is done so, if i have enough mixes available i mix everything to command the sound. i just overhauled this machine for someone and all i need to do is figure out which light system we are going with so that i can clean up the wiring. http://www.youtube.com/watch?v=4fX5O2wond4 |
Re: Light system options?
For the loader I recommend Servonaut S20 and ML4, in addittion to the SMX. Several guys use thet combo here in Norway and it will give you all the functions you're mentioning.

Here is a vid of a full scale 996G, turn up your speakers and notice how much it throttles up just turning: https://www.youtube.com/watch?v=XtlYjiBTukw and this how i set up an RC 996G: https://www.youtube.com/watch?v=cmTSjSnnCAY Much more realistic than just having the drive run the sound IMHO. |
Re: Light system options?
Nathan, i just watched more front end loader videos and i see what you mean about going to idle when you change directions... so, you would only mix the sound to the drive? What if you run the lift or turn when you are not moving, would the engine speed up on a full scale machine?
|
Re: Light system options?
Scott, yes, I would suggest you mix the sound unit in with the drive motor ESC throttle channel, and not with the hydraulic valve channels. The 1:1 wheel loaders have a foot throttle and a good operator will lift off the throttle completely, and wait until the machine is at a complete, or near stop before changing directions. It might be misleading to think the operator is on the throttle to speed up the hydraulic pump for lifting or steering, when in fact that is simply the torque converter slipping, while the engine RPMs come back up. Depending on what gear the operator is in, there might be more, or less lag, from the point when you hear the engine rev and to the point that translates into the wheels turning.
The hydraulic pumps still put out good flow at idle, so the bucket will lift and the loader will steer just fine (although a bit slower at that point), when the operator is off the throttle, but when you watch a wheel loader at work, there really isn't much time that the engine isn't running at a higher speed, except for when the machine comes to a complete stop. At that point, the loss of bucket cycle speed is minimal, especially considering the operator will be back on the throttle very soon. When dumping a full bucket at stop (bucket already raised up), not a lot of flow is needed to tip the weight. Bucket 'dig in', is usually done under power, as the operator is pushing pretty hard into the pile, with the engine RPMs up, even if the wheels aren't spinning. The torque converter may be slipping at that point, especially in the higher gears. Efficient operators will already have the bucket raised by the time they get to the truck, while the machine is backing away from the pile, changing directions, and then approaching the truck; engine running at elevated throttle through that process. So I've not known any operators to rev the engine while cycling the bucket with the machine at a stop, unless they are lifting something so heavy that the hydraulic pump can't put out enough pressure or flow to raise the weight. I know this is long winded, and I apologize, but long story short, I would not tie the hydraulic valve channels into the sound unit for this reason. :D |

My RC Excavator ( Bruder Cat conversion, no hydraulics) is powered by a 3S Lipo battery plugged directly into the Receiver with an inline uBEC to protect it. No motors. Everything is powered by servos, including the tracks. Thanks, Rodney |

So...how about an excavator? How would you mix the sound? i have never operated a modern excavator. |
Re: Light system options?
Scott, excavators generally operate with the throttle set to the optimum rated engine speed for the best hydraulic performance. Since everything on an excavator is hydraulically driven, including the tracks and swing motor, there really isn't any need for the engine to idle down, unless the operator wants to run it slower for more precise operations that don't require a lot of hydraulic force and speed, like laying pipe or something similar.
The way that I would mix the sound on a model would be with the pump motor channel, or on a separate channel with a toggle switch or knob, so the engine speed could be controlled by the operator. Simply put, if the pump is running, the engine sound should be at an elevated RPM. This could get a little tricky if you are one of the guys who likes to mix the pump speed with the valves and stick movement, throttling back the pump motor to conserve power when you aren't using the hydraulic functions. If the sound unit is mixed to the pump motor, then the engine RPMs would fall off when the hydraulic sticks are in neutral, which may not be as realistic. Having the sound mixed to a separate channel would allow the operator to have direct control over the engine RPM, and yet the pump can go idle when the sticks are at neutral (in example when you swing the base but don't need to position the boom, stick, or bucket) and the machine will still sound right. Likewise, when using the tracks and traveling. |

Re: Light system options?
You could try using a three position switch for the mixing the sound:
Pos1 - sound off Pos2 - pump speed drives sound channel Pos3 - knob drives sound channel Cheers, AP |
Re: Light system options?
You can do all that with the BEIER sound system. does the lights as well and sequences for servo's or sound and light etc.

Re: Light system options?
Has anyone experimented with an Arduino to control lighting? It does require direct programming, but there are tons of tutorials and source codes available.

i have used the 9turbo system on a few trucks now (but, using servonaut for the sound) Rebuilt Wedico rig http://www.youtube.com/watch?v=CYuJazIlx08 Trailer and rig http://www.youtube.com/watch?v=aSrcxJBN8uU i don't use the sound system because it has a separate idle and acceleration file so, it sounds wrong to me but, it is worth it for the light control to me and people i have built machines for. What is cool is there are two auxiliary light outputs and only one extra channel is required to run it. i will try more sound and light kits soon. |
Re: Light system options?
how good is the 9turbo sound unit sound wise for engine and horn thanks.
