This is the base design for my new hand-held controller. Along with a new case and display, I’m going to refactor the software to provide a cleaner interface into the clients (locomotives). Right now my ‘phase A’ handheld knows a little too much about the clients, I want a more disconnected sort of protocol. Anyhow, I’ve gotten everything to fit but the graphic interface required some new hardware so that has not been tested (other than a basic smoke test). I’ll need to write the code for that and then port parts of the old handheld code into it. The keyboard, knob and Xbee interface should not have to change much, I just need a calibration step on the kbd and store that into eeprom. I’m going to have a usb interface into this so I can write a tool on the PC to setup the function keys and display.
My new building. Everything is cut from sheet styrene on my Probotix X90. I do love this machine and working with styrene. It cuts like butter and you only have to run the router at about 7600 rpm so it’s pretty quiet.
Anyhow, this is a tower sort of depot near the south end of my bridge. It’s on stilts, With all the windows I’m going to have to make a decent interior, frosting the windows is not really an option I don’t think. Work in Progress as is everything.
Need a few more switches, so rather than make them like the last, on foam boards, I decided I should make a jig so I can (in theory) make them a bit easier. So far so good, this one came out pretty well but it had one small high spot I had to grind out. Still needs the point control bar, whatever that’s called and a waterproof servo for a throw. Took me about 3 days off and on to make this one. Now for some more epoxy, stain and seal. Good thing I don’t care about track power 🙂
Here are a couple of people I’m working on for the porch of my shotgun house. The originals were 3D printed, then I made molds from those. These are resin cast from those. Casting resin seems to be an art form unto itself, it’s difficult to get a perfect cast. Bubbles in various places produce voids, frequently in the face and feet. These came out pretty well though. Just need to clean them up a bit more and do some painting.
Here is my ‘shotgun house’. So called because you could shoot a shotgun through the front door and out the back without hitting anything. These were very common in the early 20th century, easy to build, standard lumber sizes, reasonably cheap. Often used in ‘company towns’.
Anyhow, this is my take on one. The sides are cast resin, I made two masters using (many) strips of .060 styrene to get the siding effect. Those were used to make two rubber molds, one with the brick base and one without.
For the house, I poured three of the brick base and one without, then cut them out on my band saw. The windows and door openings were cut on my X90 3D router, (cured resin cuts very much like styrene it seems, sweet). The floor and roof are just straight cut styrene sheet ‘score and snap’. The window and door inserts are also cast from resin. Everything is painted with rustoleum flats- brown, white and for the roof, black. I have it wired with white LEDs inside and on the porch but don’t have 12v out in the garden yet. Soon.
Phil, from Belgium, bought this fellow from my Shapeways shop and painted him up real nice. He was good enough to share a couple of pictures. Really great job of weathering on his locos too, they look sharp, I wish I could do that.
Latest Project. I picked up this passenger/baggage car along with the caboose at the ECSLTS train show last month. This one was $30. Good deal. Finally got to work on it some. I’ve disassembled and painted all the parts, pulled out the bulbs and put in white LEDs. A few 3D peoples will populate the seats. I also got the nice shiny truck from ECLSTS. Scale is good. Looks like it has a load of zombies…
Some pics of the final buildout of my train depot. Cut from .060 styrene on my Probitix X90. Finished up with Rustoleum flat cammo colors from rattle cans. This should fare much better out in the elements than my wooden structures, plus styrene is way way easier to work with than wood.
I use Inkscape to draw the plans, then the free version of CamBam to make the G code cutting paths. The X90 uses a Dewalt dwp611 palm router driven by a super PID speed controller. All cuts are made with preciseBits 1/32 inch 2 flute endmills.
Latest incarnation of the Phone Throttle Contraption. The phone communicates with the Xbee Controller via bluetooth, a custom app runs on the phone. This is based on previous experiments with an android tablet, you can read about that here- Android, Bluetooth and Xbee
I’m trying to emulate a generic sort of DCC throttle ‘feel’ with this. I have all of the base code written and tested, it’s just a matter of pulling all the parts together. Slowly I’m getting everything working.
I picked up a cheap Aristocraft U25B in Chessie paint the other day and have been taking it apart so I can rebuild it. The idea is to get from the toy like unit I have into at least a semi-scaled sort of model. The photo above is the closest prototype image I’ve found to what is depicted with this Aristocraft rendition. So I’m stripping it down to the base parts with the idea to install my control system, batteries and sound. And of course, a bit of paint and detail work- it is a bit cheezy with the cast color parts. Yuck. So anyhow, I’m getting there. Below is an image of the original model. More in a later post.
