If you are especially sensitive to the relative brightness between the colors, you might want to tweek the resistor values even more. The voltage requirements...

Hi all I have been talking to Dave about this problem of reversing the voltage on 12 DCCOD detectors. Applied 12+ to the Ground terminal and Ground to the 12+...
Jay, It is possible that the caps could be damaged but mostly the active components are the ones that get toasted. The LEDS and diodes should not be affected...

Change the IC and test the card, if it does not show any burn marks and it works you are good to go, else, if the LED shows the detector is working but you get...

All good advice so far. I did something similar (plugged one in upside down, always try to work where you can SEE what you're doing <VBG>)and found that...
Dear Andrew, The purpose of the control and indication plate is to identify to the train dispatcher the operating status of the effect code line. Because the...
Jay, Glad to try and help you out. All the others that have responded are also
correct in the items that could be bad on your detector boards. Just some last...
ECO Works in Wyoming, MI; and Automation In Action in Kent City, MI sold kits and built up boards a few years ago, but seem to have folded their tents. I keep...

Dear Sir, I cannot seem to find the video in question among my archives. I will take another video with my camera sometime tomorrow evening. As my camera is ...
As you all will recall I applied 12+ on the common and common on the 12+ terminals of a DCCOD motherboard containing 12 DCCODs. I have done some testing and...
You are welcome Jay. Glad only one detector board went bad. Happy model railroading to you also, Dave Thayer ... From: CMRI_Users@yahoogroups.com Date:...
Jay: It's not tough to test the logic output of a DCCOD. It's a ground. You can either test with an ohm meter to the ground (if it has a setting to sound a...
I have a question regarding the construction of the control panels outlined in Bruce Chubb's books. I've been having difficulty in locating a print shop that...
Walt, I'm planning to use matte finish photo paper printed on my Epson color printer for my panels. Using a simple 2D CAD program I have created the panel as...
Walt: I did something similar to what Chuck suggested below (print on "standard paper"), except I covered the panel with a sheet of .083" plexiglass (from Home...
Hi Walt, I'll get to the core of your problem. What we do in our Club is fairly simple. We Make full size printout copies of what we want on plain paper. We...
Hello Walt, You will have to find a print shop/graphic arts shop that still outputs film. These days they are fewer and fewer as you have noted. However, the...

Dear All I made silk screen panels a few years ago, This a my be costly. I used auto Cad to draw all drawing to scale. Then I had the drawings printed at full...
I'd like to thank all who responded with some great ideas for control panels. I may visit a sign shop now to see if they can create a black negative on clear...
having worked in the signage trade myself, I can suggest that self-adhesive vynal lettering & graphics (computer-cut) would be the way to go for you. Here's a...
