While DCC is primarily meant to power and communicate with the trains on the tracks, there are circumstances where having some auxiliary power available would be nice without having to run an extra set of wires. Maybe powering a remote turnout, an IR sensor, some animation or building lighting, or a fast clock secondary display?
We have been using the gEDA suite of schematic capture and PCB tools for a while now. Over that time, we have created a library of parts that have been successfully used in various designs. These symbols and footprints are now available via GitHub.
The ARD-LTC2499 was designed from the beginning with the intent to get as close to perfect accuracy as one could with an out-of-the-box Arduino Shield, while still keeping the cost affordable for mere mortals like us. We chose one of the best 16-channel ADCs on the market and matched it up with a high-performance voltage reference. To see what the accuracy really was, I borrowed Nathan’s 34401A meter and put them both to the test.
Have you ever been in the middle of an operating session and disaster strikes? A train derails, shorting out the DCC system, taking with it a power district, or even the entire layout. The problem is eventually fixed, but in the 5 minutes it took to restore things to the way they were, your fast clock kept ticking away. With a 3:1 ratio, all trains are now suddenly 15 minutes late.
Wouldn’t it be nice to simply press a button on the fast clock to pause time, then with a single press, restart the time right where it left off?
One of the most interesting electronic parts to come on the market lately is Berrett Hill’s Touch Toggles. They’re little electronic switches that operate by the proximity of your finger. There’s no mechanical movement, so you can put them behind acrylic control panel faceplates and other such and still operate them just by touching the surface. Unlike a mechanical switch, they never wear out, and they come with built-in indicator lights. Continue reading
The pantry in our new house had very little lighting. My wife wanted some form of light in there, but the pantry wasn’t wired for anything. So, instead of embarking on a traditional wiring project, I decided to try something new.
While we try to keep the online stock status for products up-to-date, sometimes we sell out of assembled and tested product. But have no fear, in the vast majority of cases, we can still make and ship your order within a few days.
Iowa Scaled Engineering products were recently mentioned in one of the Model Railroader Video Plus episodes, featuring Tony Koester’s Nickel Plate Road.
In this video (subscribers only) you’ll see our CKT-IRSENSE and ACC-RELAY1 products used in an automatic interchange. Each time a cut of cars is picked up, a new cut of cars is automatically pushed forward. For those wanting more details, Tony has written an article about automated interchanges that we understand should appear in an upcoming issue of Model Railroader.
