As the Super-Chuffer has been installed, one issue has surfaced more than any other.  It seems folks have trouble with getting the headlight working.  The solution is pretty simple, but easily overlooked.  Since I was having another run of boards made, I also included a small change to make getting the headlight functioning easier.  You will no longer have to add a capacitor or resistor across the TMCC headlight output to use the Super-Chuffer LED headlight feature, that has been included on the Rev. 2 boards that will soon be shipping.  You can identify the new version by looking on the back of the board, it will be labeled Rev. 2 if it's the new board.

 

The installation instructions have also been updated to reflect some installation experience.  In particular, if you're using an incandescent cab light, I've modified the connection to power that from track power so you aren't loading the Super-Chuffer power supply excessively.

 

As always, the Super-Chuffer is available at Henning's Trains on-line store at the previous link.

 

I've attached a copy of the Rev. 2 Super-Chuffer instructions to this post.

 Thanks Marty, just an incremental improvement, but everything counts.

 

Alan, it's strictly for original TMCC or TMCC upgrades.  It would work in a Legacy locomotive, but most of them have many/all of the features anyway.  It's not for MTH, they already have synchronized smoke, smoke at idle, and they also do the dynamic braking of the fan like I do for better appearing chuffs.

 

Thanks John.  The headlight made me nuts (more nuts? ) for a couple of nights until I finally got it right.  This should help some future upgraders.

 

The Super Chuffer and a new fan driven smoke unit made my old Lionel puffer like a new engine.  Thanks for your creativity.

 

Looking forward to your creations to interface with the sensor track.

Ground Lights where applicable?

I'm trying to assemble any other ideas to see what could be provided at a reasonable cost.

yeah I think I purchased all of them at York.  How many people have had this issue?  I've only done one install and I'm on my second with no problems.  Is it a noise issue or loading problem causing the headlight problem.

Neither, the headlight problem is just the design of the R2LC headlight circuit.  The triac needs a load to fire, and the input circuit on the S-C (or an LED headlight) isn't enough to give reliable operation.  That's what the load resistor or capacitor is for.  The circuit on the R2LC was designed with incandescent bulbs in mind, so this topic never came up until LED lighting starting being used.  My input circuit mimics an LED headlight, and so suffered the same issue.  Since it wasn't that hard to fix it, I added the fix.  FWIW, the ERR TMCC products have the same fix for LED lighting, but the Cruise Commander Lite currently does not.  With the new S-C version, this ceases to be a consideration, the headlight should always work if connected.

 

There is one caveat with the headlight operation with older locomotives which showed up recently.  The old LCRU, LCRU2, and any R2LC version prior to C08 have a reversed light output polarity.  This is a problem for the Super-Chuffer, and the headlight doesn't function properly.  The fix would be to change the input circuit to accept either polarity, but that's a more significant change than adding the cap, so that didn't happen this time.  The work-around is to connect the headlight input directly to the track voltage.  This enables the headlight output, and the Rule-17 lighting functions.  The only thing you lose is the ability to control the headlight from the remote.

I don't know if it's possible within price constraints but a Mars light function would be useful, at least for those non-Lionel TMCC engines that don't have a good lighting board. A lot of past 3rd Rail diesels just have a blinking LED. Scott Mann's now using the Ngineering Mars light simulator board but this is a relatively recent improvement.

Thanks, Chuck

I have thought about this too but the FEF3 you mention is Legacy equipped, not TMCC, although it's an early version of Legacy. I looked at the control boards in mine and although they appear very similar to TMCC boards I could not figure out the pins and in any event it's clearly using a different code. Over to GRJ to say whether you could get the smoke function at idle using a Superchuffer board in this model.

The only issue I see is the chuff switch.  If this is the 6-11116 Legacy FEF, it has a standard chuff switch and the installation would be the same as for a TMCC locomotive.  From the user's manual, it uses incandescent bulbs, so you may want the Rule-17 LED headlight, and possibly the cab light control if it's not already handled by the Legacy electronics.

 

As far as the MARS light, I did consider that, and I even have a working  prototype MARS light model.  I just don't have an extra pin on the uP, and I'm not ready to spend the money to retool and use a higher pin count uP.  I'd also have to add a programming jack as any more pins would dictate I use a SMT part, so I wouldn't be able to program them before installation.  Of course, I'd also have to add more connector pins.

 

FWIW, I use the Ngineering MARS simulator when I need one, they're great.

Well, I for one would be in the market for a diesel board like this, at least to get the kind of smoke and ditch/cab light controls you mention, which is not present on many non-Lionel TMCC engines.

 

I don't know whether you could include on this some kind of DC output for the Ngineering Mars light simulator. I've ended up wiring mine to one of the motors - not an elegant solution but (a) the board needs a DC current supply and (b) I prefer the light to be off when the engine is not in motion.  

 

P.S. Thanks for the advice on the 6-11116 Legacy FEF3. The Rule 17 lighting and the cab light on this model are already controlled by the Legacy system and they work fine on mine. The lack of smoke at idle is the only real issue.

Since you just need smoke at idle, you can simply wire the track power to the Super-Chuffer on pins 1 & 2.  Wire the ungrounded side of the chuff switch to pin 5, the chuff input.  That will be in parallel to it's connection to the motherboard.  One side of the chuff switch is grounded, the other one is the actual chuff input to the R4LC.  Wire the smoke motor to pins 6 & 9, with pin 9 being the positive lead to the motor.  So, with five wires, you'll have the smoke at idle, should be pretty simple.  Obviously, you disconnect the smoke motor from the existing connection!

Directions much appreciated John. 

John, im still hoping for the diesel board as all my 3rd Rail Diesels don't have a good smoke output and the lighting sucks. Cab light, ground lights, reversing headlights would all be nice to have. right now theyre as the factory sent em and when I get into em Ill just pull a lot of the lighting and render it useless but itd be a nice option to make em the way theyre supposed to.

Well, the actual volume of smoke won't be affected as that requires modifications of the smoke unit, or at least some maintenance.  Similar to the Super-Chuffer, I control the behavior of the smoke unit, and for dumb units, I can alter the smoke volume for idle, but increasing the smoke is a different scenario. 

You certainly should have directional lighting, but the Rule-17 lighting and cab light control is something else.

GRJ,

In your Super Chuffer documentation "Figure 1: Board Connection Diagram" you show a 470 Ohm 1/2W resistor connected to Pin 3 / the R2LC Headlight output on one side and ground on the other side.  (Is this what's known as a pull down resistor?)

I read that you reworked the circuit design in Rev. 2 to eliminator the headlight resistor, so I was just making sure that this 470 Ohm Resistor was still needed.

Also, if I want to use an LED for the cab light, can I use pin 9 or pin 10 as +5VDC with a 100 ohm resistor?  Your documentation says using track power is better, so should I use a resistor / diode combo to drop the voltage from a pickup roller to power the LED?

Thanks!

Nope, no resistor needed.  I actually also found out that even with the older design, a .01uf cap works as well and doesn't present a constant load.  The resistor was to force the triac to fire if it didn't have a resistive load, turns out the cap does the job as well.  The current version of the Super-Chuffer board has the .01uf cap on-board.

I recommend using a 470 ohm resistor in series with the LED and connecting the positive side to track power.  The cab lighting output already has a diode in front of the FET switch, so all you need is the resistor in series with the LED and you're set.

Just an observation but if you have some sensor in this diesel board that automatically turns ground lights on and off at a certain maximum motor speed could that same circuit in there be able to do the same with the smoke unit? I am thinking along the lines of ALCo/BLW turbo lag here. Lots of smoke for low ALCo speed then switches to minimal smoke when motor obtains a revolution consistent with 50 mph or more.

This is a circuit that I did for the for use with the Super-Chuffer in a steamer that will drop the smoke volume when you stop.  If you wired the cab light ctrl shown to the Chuff-Generator Ground Light output, it would do the trick.  When the Chuff-Generator ground light output turned off, the two diode bridges on the left are shorted out and allow more power to the smoke resistor.

GRJ,

I'm progressing through a Super Chuffer upgrade of my N&W Class A (28052).  I'm ready to tie into the chuff switch, but I want to make sure I'm using "best practice".  Should I tie the Pin 5 chuff input into the wire that connects the chuff switch to the existing main board (the chuff switch would "Y" - one wire to the main board and one to the Super Chuffer)?  Or, should I use chuff repeater on the Super Chuffer to run back to the chuff input on the main board?  I'm using an ERR Cruise Commander "M" (I don't think it matters), but was wondering if the Railsounds needed a separate chuff signal.

Thank you!
