One of our beta testers is the well known Technic builder Sariel from Poland. He has literally written the book on Technic, having just released his second edition of The Unofficial LEGO® Technic Builder’s Guide. He has very meticulously tested the PFx Brick and provided us with a great deal of valuable feedback. Furthermore, he has generously taken the time to compile this showcase video shown above (and on his YouTube channel).
This video systematically covers aspects of the PFx Brick physical design, capabilities, the PFx software app, and lighting effects. He shows the brick operating by itself as well as inside two Stars Wars spaceships! The feedback we have received from Sariel and our other beta testers has been immensely useful. In fact, we have already incorporated some of their suggestions already.
This testing process is a necessary part of getting a product ready for market. It has to be real-world "road tested" to ensure reliability and to make sure we've captured the key features demanded by builders. Our confidence in the PFx Brick has been consistently rewarded with durable, consistent, and reliable operation--all thanks to continuous testing within a variety of LEGO models!
As a continuation from Part 1, the video shown below discusses how the PFx Brick can be configured to exploit features specifically beneficial to LEGO® trains.
The discussion is split in to four main topics:
- Remote control setup
- Motor configuration and operation
- Lighting setup
- Sound effects
The remote control setup discusses how a typical handheld remote can be configured into logical groups of functionality. It also shows how remote control actions can be assigned completely freely and how functionally dense a remote control can be configured. The motor configuration topic is the lengthiest since it covers almost every aspect of advanced motor control in the PFx Brick including speed control modes, speed steps, dual motor operation, speed curves, acceleration, and much more. Sophisticated and automated lighting behaviours such as directional headlights, flashing ditch lights, and adjustable brightness are discussed as well as loading and configuring sound effects.
The video includes a great deal of helpful illustrations to help explain more complex topics, especially those related to motor control. After completing two videos on this topic, it became clear to me that even more videos could be produced since some areas of functionality could benefit from deeper examination. This applies especially to the topic of sound effects.
- Syncronized control of two motors each with a dedicated motor driver channel.
- Adjustable speed curves to suit locomotive type.
- Adjustable limits on both minimum and maximum speed.
- Simulation of momemtum with programmable acceleration and deceleration rates.
- Smart directional headlights.
- Special light effects such as flashing ditch lights, MARS/Gyralite beacons, flickering fire boxes, dimming, and much more.
- On command sound effects for bells, whistles, horns, prime movers, chuffing, brake squeel, couplers, compressors, machinery, crossing gates, and much more.
The video shown below is the first of a two part series which discusses the installation aspects of fitting a PFx Brick to a typical LEGO® train. In this video, we modify the locomotive that is part of the City freight train set #7939. However, the techniques and methods shown are equally applicable to virtually any LEGO® train. The challenges a builder will face are the usual factors such as space and clearance for items such as wiring, motors, battery boxes, etc.
- Bi-directional head and tail lights consisting of a pair of 3 mm LEDs at each end.
- Two Power Functions™ train motor bogies each connected to a dedicated motor channel.
- M Speaker brick for sound effects.
- Rechargeable battery box with top-mounted access to power switch and recharge port.
- Side access doors to allow easy connection of a USB cable to the PFx Brick for programming and configuration.
