Model Railroading Clinics

Clinic Presenter Chris Sgaraglino




Chris Sgaraglino found his modeling passion primarily in operations, and in the late 1990s, he built a large HO layout in a finished 4-car garage that modeled the Western Pacific Feather River Route. After an extensive time-out, he started a N Scale operations layout of the D&RGW's Marshall Pass route from Salida to Sargents.

As a visual editor and creator, Chris knows that audio is 80% of the experience of a movie. He wanted a more realistic feel of everyday life on the railroad, and what better way to do that than with audio? This quest led him to the world of Arduinos and the power within.



CLINIC - Make & Take, Arduino Speed Matching Speedometer $$$


Introduction:

This is an Intermediate Level clinic. In this clinic, we will build an Arduino Model Railroad Speedometer for Speed Matching that will take all the guesswork and headaches out of the old-fashioned "chase" method of speed matching.

Registration is Required for This Clinic:
  • The clinic is limited to 10 Hands-On Participants.
  • Silent Auditors are permitted.
  • The registration Make & Take fee is $32.
  • A Kit will be provided to the participants.
  • Participants must have a laptop with Arduino IDE installed and a UNO or Nano communicating via the IDE software and successfully running the Fade Sketch under Basic Examples.
  • The 2 hour clinic is scheduled for Saturday, August 26 in Tate 6 at 8:00AM.
  • Speed matching consists of DCC locomotives is vital to the health of your locomotives and a smooth operating layout. The objective is to get your locos to run at the same speed. Not just the consist pair, but all of them so you can consist any of them anytime with any loco in your fleet.

    What you'll learn
  • Build and program an Infrared Speedometer with an LCD readout.
  • Build your speedometer on a solderless breadboard.
  • Program a Sketch to read IR Sensors, set desired Scale, and calculate Scale speeds.
  • No previous electronics or programming knowledge is needed.
  • All electronics and programming principles will be taught from scratch.
  • This course includes:
  • 2 hours of hands-on instructions.
  • All the necessary components as a kit.
  • A Fritzing circuit diagram.
  • The finished Sketch.
  • Requirements:
  • A laptop (Mac or Windows).
  • Arduino IDE is already installed on your laptop.
  • Arduino UNO or Nano communicaEng with IDE soFware and successfully running the Fade Sketch under File > Examples > Basic > Fade.
  • If you don’t have the Arduino IDE on your laptop, attend Speed Muller's “Arduino Setup” before this clinic:
    Sunday August 20 @ 4pm
  • Optional Recommendations:
  • If you have never worked with Arduinos: Speed Muller's “Arduino for Beginners, Hands On”.
  • If you want to know more about Arduino software: Dr. John Bate “The Arduino SoFware” Clinic.
