 The Duomatic itself. Stop. (Collaborate and listen.) You just bought one of these fancy Lemke ballast tampers, and you are considering converting it to DCC. You can read a little German, maybe, or at least you can work from photos; or you found another guide on the web. It doesn’t look so hard. Don’t believe everything you read. 
My family’s Christmas, er, New Year’s layout, Shogatsu, has been retired for the year. We haul it out of the basement for only a couple months each year, around New Year’s, to work on it and display it. This year’s time is up. We made some small progress on it, especially in forestation and village construction. New concrete retaining walls were built, and our village received a bath-house, a liquor store, a long string of merchant stalls for the New Year’s festival, and a portable shrine being hauled down the main street. It also received a new bit of rolling stock, a Tomytec モ1030. Before we packed it up last weekend, I made a video of it, below. 
Test-type in Cylon training school. A couple of nights ago, I hooked my custom LED Driver up to an Arduino running some custom software, and 16 LEDs. And, who’d have thunk it: Worked on the first try! So many things could have gone wrong between the circuit design, the hand-soldering (jumpers, burn-outs), and [...] 
LED Driver prototype 1, fully populated. Having recevied my PCBs, all that remained was to assemble the parts onto one and test it. Assembly took a couple of hours, but that’s because I was being careful at each step. I can now say that I am pretty comfortable soldering SMD components; having a [...]  オロネ25-901 (with body-mount TN coupler) and オハネ25-100 (with truck-mount TN coupler) Not every Tomix or Micro Ace train accepts the fancy-pants body-mount TN couplers. Sometimes you have to make do with compromises. Which is what Tomix’s truck-mount TN couplers are: A compromise. They work, but they’re not nearly as cool, and don’t look quite as good. And they’re harder to install. But, in the end, I think they are still worthwhile to bother with. Here’s how to install them. 
The boards I received in the mail, about two inches long by one-and-a-half wide. I built a prototype. Then I designed a PCB. This weekend I received a set of my very first custom-designed circuit boards. It’s quite a thrill to hold an item manufactured to your own specifications. Best of all, I [...] Just an update on this project. I managed three more cars in one evening, for a total of four out of seven. It’s tedious going, but I’ve got the hang of it now. What’s slowing me down is cleaning the trucks: They’re filthy! Spent the evening with a bowl of rubbing alcohol and a [...]  Kato 10-173 651系 'Super Hitachi' So, you have just purchaed Kato 10-173 651系 (651-series) “Super Hitachi”, and want to know how to convert it to DCC. I’ve just begun this process myself; here is part one (of many!) of my report. The 651系 is factory-fitted with interior lighting, a nice touch. But, being bulbs, those lights have to go. For one, they draw a ton of current—55mA/bulb @ 9 bulbs = almost half an ampere!—which limits the number of trains that my Digitrax Zephyr can drive simultaneously from two to one. For another, bulbs get hot when powered by AC, and DCC is AC. Some people have reported that Kato’s bulb-based interior lights cause meltdowns when run on DCC. I don’t have a link, because I think this claim is largely apocryphal, but Kato nevertheless cautions against using their bulb kits with DCC. Or at least they did until they discontinued those sets. Anyway, Kato’s LED interior lighting kits aren’t compatible with the 651系. You’ll see why below. This means we’re going to have to improvise something new if we want to run out 651系 on DCC.  It lives! Tomix EF81 with working DCC provided by a TCS CN-GP. [Update 7 July 2010: The decoder failed by February. TCS advised that the CN-GP is a very delicate decoder; consequently, I cannot recommend this installation method. Currently looking for a new method of installation. Watch for future posts.] Read Part 1. It’s done. Well, almost. [Update 10 Jan 2010: Yep, it's done.] Anyway, it works, and that’s what counts. Here then I recount the two hours I spent last night making it work, and the year of effort that culminated in those two glorious hours. (Yes, it takes me about one year to install one decoder. No, I’m not that slow: it’s just a function of how much free time I have, and how I choose to spend it.) Without any kind of warning device, the local commuter train is likely to strike village traffic! Shōgatsu has a road, or part of one. The as-of-yet unnamed village (suggestions, anyone?) needs a road connection to the outside world—trains run on only a very irregular schedule and often bypass the station. Building the road [...] |
