Some product images & MCU system updates

[railflyermodel]

Evan Kayahara built this undec Kato unit using a bunch of our parts. The roof was reworked with our DP 6600 Sinclair Antenna which are photo-etched multi-layer products.

SD9043MAC using our DP 6205 Pillow Blocks and DP 6216 0.015" OD Solder.

This replicates the traction motor conduit.

Here you can see two of our DP 6203 Salem Filters, the smaller one seen to the right is also included in this kit.

They are slide injection molded with photo-etched brackets. They are also cored for wire.

Also seen is the DP 6207 Under-frame Bell on the left.

More traction motor cables.

This front view shows our pin lifters and ditch lights. DP 6304 is accurate for this locomotive. Also note the SMD402 LED's mounted in the DP 6631 Ditch Light. The SMD402's are small enough to fit in our scale ditch light housings.

The warm white LED's lit up. We have Warm White, Neutral White, Signal Green, and Red, both wired and not wired. The SMD402's work and have just a 0.5 MM X 1.0 MM footprint. The White LED's are 3.0V, the Green 2.1V, and Red 1.9V.

Our MCU System is slowly trickling in. Here is the first production run of Truck PCB's.

This side of the Truck PCB would face the bottom of the cab floor. Included are all of the resistors for the LED lighting.

Solder pads for the full prototypical locomotive lighting are the squares seen around the outside edge of the PCB. 4 circuit headers for the traction motors are seen here to enable quick removal or plug and play of our traction motors.

There are 23 solder pads per Truck PCB for a total of 46 per locomotive. We also include programming for multiple light effects and all circuits are optimised for SMD402 LED's.

This effectively makes our MCU system 46 AUX output.

The Sound MCU layout is done, its gone into fabrication and assembly. We use a 32 bit ARM7 processor for motor control, 4 Gb for flash which gives better than CD quality sound.

The Non-Sound MCU is almost done Assembly, the firmware is almost ready for DCC testing so we can show a running drive soon. This is also equipped for Battery/Wireless operation with no track based signals.

This image shows our DP 6190 GP Jack Pads, this was one of our first injection molded products.

Here are some more images of Stan's build, the thread for his build got locked before I could post them.

awesome work on everything. What will that flat cable plug into?

 

[railflyermodel]

The Motor Control Unit (MCU) system uses a modular approach.

What you see is the Truck PCB. This is the connection point for the traction motors/wipers and LED lighting for one half the locomotive.

The ribbon connection will go back into the hood and connect with the MCU PCB. The MCU PCB has connections for a rear and forward Truck PCB. This is what makes the system contain 46 AUX outputs for LED lighting.

The other part of the system is the Motor PCB which connects to the MCU PCB.

This is where the battery IC's, voltage regulation, and motor control circuits are contained.

To change the system between Sound and Non-Sound, we just change out the MCU PCB.

With the ribbon's we are able to reuse this electrical system for all of our planned locomotives. With some creative work, in a non-battery locomotive, you can open the hood sides and place a prime mover, keeping a fully functional locomotive.

Thanks,
