Puff & Chuff fixed 90%. It took days of worrying and thinking and testing and reading. Finally!!

For those interested, the problem from day one was over driving all the components. Realize I am on purpose taking Track AC power and driving all the stuff. At first it was the motor. I converted the Vintage Motor from its wire wound steel fields to 3D Printed Fields and super Magnets for power to pull the armature. We over heated a few reverse boards as we worked thru this process. Finally we got the right parts for reliable operation. This Puff and Chuff is actually a little more complicated. We have a new fan drive smoke that is a unique design that took me years to develop and refine. I have tried to get a pulse Puff of smoke and with the Royal Blue upgrade kits I wanted two puffs and chuffs per Rev. But the fan was over running the brake dwell time and it was just puffing smoke. I started to dig into this issue weeks ago but had no success. I bought books and talked teammates. Then I can to the conclusion we were over driving two key parts. The relay I used to switch from idle to Puff and chuff. And the motor used to drive the smoke fan. I had to use a rectifier and 2 Buck boards to get voltage controlled. Power flows from a 1950 Flyer transformer to the track, up the tender trucks to a pair of rectifiers to condition the power from AC to DC and Distribute Power (PDB) and then out to the various devices. One to the Smoke Controller, one to the Motor Controller (Reverse) Board (MCB) and one for P&C Controller. The MCB then sends forward or reverse power to the DC Motor Brushes. It can run DC Can motors, But I like converting the Flyer Vintage Open frame motor to DC with a Magnetic Field Assembly I created to mimic the 1950s DC Motor fields from AC Gilbert, only better. The power path to the Puff & Chuff Board (PCB) runs through two sources. To tell the PCB whether the engine is at idle with track power or rolling out under steam power. There is a relay in the PCB that is told we are idling use slow smoke fan speed, or we are rolling with motor power so switch to Puff & Brake operations. I use a rectifier to sense if the motor is powered or off. The challenge was I needed to know regardless of direction when the motor was powered. The MCB sends a DC power but will switch positive and negative to go forward and backward. The rectifier will take in DC and strip out only positive for one output and only negative for another output. This allows the rectifier to tell the relay to fire up in either forward or reverse, which produces Puffing smoke. The circuit was working but the relay was not reliable causing me to think the Puffer was at fault.I fixed this issue by adding a mini volt regulator to the output of the Rectifier. Now I had a power signal in either direction and could regulate the power lever so as not to overdrive the relay. I found the unregulated power was tracking with the track speed, faster more voltage and my relay was rated for 3 -5 volts. Uh Oh. Now that this was dealt with I had to rework the puffer circuit as well. I have two power sources for the puff motor, one if fan motor drive, the other is a motor brake. They operate off a mini limit switch. The switch is operating by a two lobe cam attached to the smoke gear in the engine chassis. The smoke gear is identical to the drive gear on the underside of the motor worm shaft. the smoke gear is located on top of the motor worm shaft. so for each revolution the switch is triggered twice. The switch has two modes, Normally closed and normally open, it also has a third pin for Signal power in. I feed that input pin the track live power from a Buck Boost (BB) board in the tender. For the transistor to operate properly they require 5VDC, so the BB is set to 5V out. The BB is feed track power after it is converted to DC by the PDB. Then with BB set at 5V out, it routes that 5V to the PCB at two input points. The main Input to the Transistor Logic flow and the input to the Puff & Brake limit switch. Power at the limit switch is routed through two transistors in two separate circuits to the Relay and out to the Smoke Fan Motor. One is to fan operation for smoke flow, the other is a fan motor braking function to stop smoke flow. To Mimic the pulse of chuffing steam and smoke of a steam engine. The other power route runs to a trim pot and is the Idle power for the relay to send out when there is track power on but No Motor power signaled. The provides a slow speed fan to simulate sitting at the station warming up the boiler waiting to depart. So there it is in all its glory, the Next Gen S Puff & Chuff Process. I include Chuff because the same cams will hold a small magnet to trigger the Chuff Sound board in synchronization with the Puff of smoke. Now you know the rest of the story. This small circuit is the Switching Logic controller in Hardware, digital components 3 and 5 volt powered circuits. One day we think this small but complex electronics assembly will yield to a software solution. With the newer microcontrollers ???
