This may not apply to the MR circuit, but I have found that many of the commercial lighting, voltage regulator circuits do not pass enough AC bias current to...
Steve Once propulsion power is applied, the detectors work properly even without the added resistor. With DCC having a constant voltage on the rail about 14V ,...
... Hi Earl, Thanks for this very useful post. What do the X and Y values represent in the chart? I can understand the wavelength range but the graph is more...
Getting back to the original point of this thread, I believe I've found the correct part numbers for the Tomar LEDs. They are Avago HLMP-6300,6400, and 6500....
... understand ... wavelength. ... I moved the color chart to a folder "Signal Colors" and have added a couple of other charts that more clearly explain the...
I wrote an article about building signals which appeared in the July 2006 Model Railroader. I also used 3mm leds from Digikey for more than 100 signals I have...
Hi all, I've just ordered my first kits from Don, and I'm looking for some soldering advice before I get them and get started. I've assembled over 20 Fast...
I use a WELLER 35 Watt iron for all my card assembly. I use a fine point conical tip to ensure heating is on the pad and part. It is true that the DCCOD style...
If anyone is interested, I have posted some photo's of my Color Position Light signals and dwarfs. They are in the photo section under "Grafton Div CPL'S" ...
Mike: For #3, I use the hard rubber washers for faucets. Works very well. A store like Ace Hardware has them non-prepackaged where you can go buy them in...
35 watts is a little much. I use a 20 watt. NEVER use seperate flux. USE ONLY electronic tv radio solder with a rosin core (meaning it is hollow and has the...
Having read further on Michaels letter. I use radio shack 60 -40 solder and no flux what so ever. I have heard nothing but bad things about flux and electronic...
G'day Michael To answer some of your questions: 1) I do my soldering using an Adjustable Temperature Soldering Iron (use between 300-400c, I use 350c)- mine...
One last thing about soldering flux. My Dad was an old time "radio" man and built his own short wave receivers. He always used soldering flux, so naturally,...
Hello Michael, The iron is okay as long as you wipe the tip occasionally with a damp sponge to keep it from getting too hot when working with smaller pads. ...
Michael I use a soldering station which allows me to adjust the heat. For example soldering the nuts on boards I turn the heat up. Soldering LEDs for...
Michael: Do heed the advice on added flux when soldering, any ROSIN core solder for ELECTRONICS will have enough flux to do the job. You may need some ...
Thanks to everyone for all the great advice. I think I'll be in good shape when I get started. One additional question - in soldering my Fast Tracks switches...
... I've lurked on this forum for a while now and will insert my first comments. 1) The solder I use is one designed for circuitboard repair. It is about 1mm...

Michael, back when I was building FastTrack Turnouts they advised me to use Acid Flux, as building the Turnouts IS NOT Electronic type work, but more ...
... The solder I got from them was coreless - it was very thin solid solder with no flux of any kind in it. They recommend acid flux - which is OK in this...
I just walked away from the bench to check the e-mail and ran into this topic, so I'll add my two cents worth. The advice is generally good, especially for the...
Group: This is going to look like a flame... T'ain't! To all those worrying about soldering, Wayne raised an odd specific example with steel. I'm not going to...
... This t'ain't a flame either... I've composed and trashed two or three replys to this thread because I just didn't want to start a nasty discussion(?) like...
I'm working on the software for a signal system at a club. The hardware people finally have all the boards in and I am able to do some testing, which is...
Paul: Absolutely try the terminator with a run that long...or that many boards. We've found it can make a big difference. For the noise, if you aren't already...
Hi Paul Details are needed. Running what software Qbasic, Quckbasic Visual Basic, JMRI Real Basic under Windows or Dos. Did the boards pass the serial...
