Makerfaire

Whiskeydrome

This was our second visit to Makerfaire. Just like last year the event is overwhelming, exciting, and fun, all at the same time, and everyone takes home different impressions and new ideas.

One can spend most of the day walking the booths in the big Expo Hall alone. Notable booths and things we liked the most:

Building a foam rocket. Pascal enjoyed building and launching a rocket made of foam pipe, duct tape and foam sheets.

In the South Lot were plenty of odd contraptions (partially) made of bicycle parts, that where plenty of fun to ride.

The WhiskeyDrome guys were back. Roland, Pascal, and myself watched for quite a while. They even ride hands-free! Awesome.

The Crucible Village. They showed a truck that had 8 remote-controlled fire blowers installed on the bed. Gas. Fire. Heat. What else can you ask for?

Levitating Fountain

The Expo Hall. Many small and medium vendors and organizations. Electronics, Arduino in particular, was almost everywhere. I looked specifically for booths that did not show how to do something with Arduino boards (or did it in a way that wasn't immediately obvious). Gluemotor looked like an interesting project. I loved the "Levitating Fountain", which uses PWM and stroboscopes to manipulate a stream of water so that you see droplets falling down, and up!

Pascal was fascinated by the mechanical pinball machines of the Pacific Pinball Museum.

After a quick lunch (and waiting a long time in line to get to the order window), we explored the "dark hall", which featured a demonstration of Intel's Computer Controlled Orchestra . I saw part of the performance when we got into the hall. When they got ready for the next one, I got the kids, and brought Pascal to the front of the crowd surrounding the installation. He watched the whole thing almost motionless. Afterwards, he said: "That was so cool. Unbelievably cool."

Operating and modifying MATE's Underwater Robots kept Pascal busy for a long time, just like delving into playing with Bloxes a few feet away.

Gon KiRin is a kinetic dragon sculpture that spews fire, and you can climb on it, in it, even lounge on couches. When we walked along one side, one of the guys winked Pascal and Tatjana over and told them to press The Button. ... Pascal pressed it first and out spew a 10 ft flame from the dragons mouth! Pascal's face lit up, and he pressed The Button again. And again. So much fun.

As was building your very own toolbox from sheet metal at the booth right next to the Coke and Mentos stage.

We spent most of the day at the Faire, and everyone had a great time.

"Des koennen sie alles senden was ich gesagt hab"

Ich mag den Seehofer ja nicht so unbedingt, aber das hier ist klasse:

Hiding the semaphor machine

I'm using old-style Maerklin semaphores for my signals. The masts are attached to a dual-coil switch machine which is quite bulky. In station areas I managed to hide them between the tracks and lowered them into the roadbed.

However, Emsingen's entry signal A is out in the middle of the forest, and I do need the machinery to be accessible for servicing. In this case ended up fitting a sheet of styrene over the space, brace it with some wood, and cover the ends with stone sheet.

Placing the cover at the signal showed that I didn't get the cutout for the mast quite right and had to enlarge the hole. I'll put a telephone cabin in front of the hole, so that it's not quite as obvious. Yes, this is actually one of the triple-coil semaphors, so the cover needed to be quite big.

Test fitting.

Update 2012/05/13:

Cover painted and topped with a thin layer of fine sand.

I painted the base and topped it with a thin layer of fine sand. Looks much better than the stark white of styrene.
The telephone box looks way out of scale. I wonder if this was a N-scale kit...

Making the road narrower

Narrower access road.

Well, this didn't quite come out the way I wanted.

Looking at the access road today, it feels like I'm building a German Autobahn through the Black Forest, or at least a major two lane highway. I contemplating ripping out the access road and starting over, but before I did that I traced a narrower one lane road on the existing shoulder and used a hobby knife to cut through the Scuptamold-tape-cardboard contraption along the edge of that narrow road. Next I simply cut off a few millimeters of material, straightened out the edge, and voila ... this looked much more like what I had in mind.

The first photo shows the new road after I made the cut and re-arranged the slope. The former edge of the road is half-way down the embankment now. The second photo shows the situation after patching up the cut with Scuptamold.

Embankment patched up.

Steinlebruecke

While in Zurich my Dad gave me a great idea what to do about the access road to Steinlehof after it crossed Steinlebruecke. The elevation change between the forest in the background and the Steinle area on the other side of the tracks is  almost 2 inches, which would have resulted in a very step, odd-looking bridge.

Building up a shoulder along the hill for the Steinlehof access road

Instead, I built up a shoulder along the hill, which raises the access road to almost the same height as the forest. Since this doesn't have to support any weight, this is made from cardboard with some styrofoam bits underneath and covered in masking tape and Scuptamold.

When I filled in gaps around Steinlehof the last time, I left the building in place while the Scuptamold dried, which basically glued it in place. I didn't install lights, nor painted the building yet. Ooops.

Looking south on the dark side of Steinlehof. This view is only possible from camera

I managed to do touchups and paint the roof and most walls with the building in place. This took care of most of the plastic sheen and visible glue spots that bothered me. I will cut a hole from inside the hill to place some light inside the living area of Steinlehof.

Time to start thinking about a design for Steinlebruecke.

Dolderbahn

The Dolderbahn is a cog wheel railway going from Zurich-Romerhof to Dolder Bergstation. While there's not much interesting up there for tourists (unless you're into super-expensive hotels), the view is quite nice. Here's a shot of the snow covered Alps taken from Dolder Bergstation.

Creating a Quick and Dirty Operating Scheme

"A"-Town on the right, "D"-Town between the two potted plants

This week I visited Balazs' layout and we made quite some progress on adding industry tracks, sidings, and conceptualizing how running an operating session on his new layout would work. This tabletop layout does support fully automated running, too, so the objective was to add enough operational opportunities to keep a few operators busy and entertained when running the layout in manual mode.

During automated operation, the layout is treated as a mostly double-tracked loop, with two single track choke points and one large interlocking that allows trains to run return loops, or take short-cuts.

Industry tracks are labeled with sheets of paper in "D"-Town

For manual operation, I modified the concept and think of the layout as a single track mainline with sidings. The sidings give operators switching an industry track space to hold cars being switched, as well as a logical hiding place to not block main line traffic.
For each industry track I defined what kind of car type the track would accept. I chose a distribution of car types that roughly matches the fleet Balaszs has. Due to space constraints, most "industries" are single or double track spurs, mostly off sidings. There is one large industry with a more complex track arrangement.

To create a feeling of location, I gave each industry a name, as well as town names (well, the town names are not exactly imaginative: A, B, C, D, E, and F arranged roughly clockwise along the loop of track). Once that was worked out I placed sheets of paper near the tracks indicating location, industry, and what kind of cars the track would accept.

A small, stub-ended classification yard existed already. We added a dedicated track to be used as yard lead to disentangle the lead from the single A/D track.

Industry tracks of "C"-Town and "E"-Town

Now that we had industry locations and respective tracks, it was time to define trains. There are almost 30 car spots, maximum train length is about 8 cars, and multiple operators are expected to work the railroad. There will be local freights, through freights, as well as extensive passenger operation.

I broke up the local freight operations into 3 trains. One would run from the Yard to towns A and B, one would cover towns C, E, and F, and finally there would be a dedicated run to switch the large industry in D.

To extend the length of the runs, and make the job of a dispatcher a bit more interesting, the local freights need to go all the way around the layout between switching two towns. All trains are turns, so the engineers need to pay attention to trailing and facing point turnouts in the industries to switch, and in the worst case run around their train on a siding as needed. For each train I wrote station/loop order on a sheet of paper, so that the operators know what's expected of them.

Car routing works by type of car. If a track asks for a box car, any box car the train brought along from the yard will do. The engineer is expected to keep track which cars he picked up at an industry on the way and make sure to bring them back to the yard. However, even if a car or two slips through, it doesn't really matter that much.

This operating scheme was developed over the course of about an hour, and we ran a session with all 3 local trains, plus classification in the yard the same evening. There's certainly room for improvement and fine-tuning. However, for something that was made up on the fly, I was pleased to see that it worked well enough to give a feel for how switching on the layout could work, as well as quickly identify areas both on the layout and operationally that need further refinement before investing a large amount of preparation time.

Plus, we certainly had fun, both building out industries and track arrangements, as well as operating ... In the end, this is a hobby. Enjoying what you do is the only thing that matters.

Going for 600 kWh

Now that the sun is finally shining regularly, our PV solar system is busy producing electricity.

In December we topped out at about 10 kWh each day pretty consistently (it was mostly sunny, but cool), for a total of 290 kWh.

In March the total was 430 kWh with a very uneven distribution over the month. Some days saw production up to 20 kWh, some days barely broke 5 kWh.

This month we're already at 390 kWh hitting almost 25 kWh most days, and a third of the month still in front of us. If the weather holds up we could be topping 600 kWh in April.

Last year we produced 600 kWh per month from May to September, and while high energy production in the summer offset the costs of winter usage generating a net negative dollar amount, we didn't get a refund at true up time because we were not a net producer in terms of kWh. Oh well ...

Our inverter reports usage data to Solarcity's SolarGuard monitoring service. The highest grossing month was July 2008 when we produced almost 700 kWh in one month. Our PV system is composed of 22 180W DC panels for a rated peak AC capacity of 3.2kW.

Steinlehof foundation

Steinlehof is a typical Black Forest farm house. Since the ground has a bit of a slope here, I needed to build up the ground for the house. A nice overview shot of this area is in the posting about building Hochwald.
This patch is for rough leveling of the house. Next up is a bit fine-tuning, patching holes and sharp edges followed by painting and texturing the hill, as well as building part of the access road. I still need a design for a simple wooden bridge across the tracks in the background, and will probably end up scratch-building the bridge from styrene and stripwood.

Last weekend I spent some time to ballast more track. This time the approach to Hochwaldtunnel. Right now, the ballast looks too clean and uniform. I will add more trees and bushes later, along with more weeds to get the effect of overgrown vegetation around the tracks that I see on many photos of the Schwarzwaldbahn. 

Eventually, there will be a small Schrebergarten in the foregound , roughly in the area of where the cup and chisel are located. 

More car spots in Talheim

Talheim had a fairly modest amount of car spots, mostly around the Werner & Soehne machine factory, the loading track at Kopper Furniture, and a couple team track spots. Both Werner and Kopper had a simple track arrangement with one turnout. Well, that's changing ...

It all started with admitting that the freight shed I built over the Christmas break just doesn't work very well in Emsingen. It's too small for the traffic, and amount of goods it would be supposed to store. I started looking for another location I could put it at. I needed a spot with a track, road access, and a purpose.

Thus the freight shed became an agricultural supply. The only available spot on the layout was at the end of the Kopper Furniture shelf.

I had a location and a purpose for the building, now I needed the tracks to get there. The simple track arrangement on the shelf became a bit more involved.

Experimental track arrangement around Kopper Furniture

Kopper Furniture continues to be a large operation and will be represented as a modern half-relief building against the backdrop. There will be 3 numbered doors to spot cars at.

The track next to the shed extends all the way into the corner of the room (after I took the photo I also extended the shelf into the corner). The track next to it is a team track, and doubles as access to the sawmill track in the back.

Finally, the stub track branching off the curve towards the wall will get a small loco shed for the resident switching engine in Talheim (maybe a Koef?)

All of this adds a bunch more freight car spots, and it opens up the possibility to originate a switching job out of Talheim, even exchange cars in Emsingen and return. I really need to get more locomotives operational now.

Closing the gap

Odd-shaped hardboard piece to close "the gap"

When I originally built the Talheim station base board, I didn't intend to create the operator pit in the middle of the layout. The area was supposed to become a lake and the Welzbach ("Welz creek"), which gives the Welztal it's name, would provide power to a small watermill. Well, ... that didn't quite work out as planned and when I installed fascia inside the pit, there was a three inch gap between the end of the creek modeled into the station base board and the fascia.

First test-fitting of left-over Hydrocal rocks

Several months ago I built up the hill next to Tiersteintunnel and covered it with masking tape. A few weeks ago, I cut a piece of hardboard to fit the gap, and glued it in place. Last week I started laying out some left-over Hydrocal rocks, and finally today I plastered everything in place (well, actually I used Scuptamold for the last step). Now it's on to add some paint to the rocks and creek bottom.

Hydrocal rocks fit in and set in place with Scuptamold. 

The photo above also shows a close-up of the ballast I added last week.

Finally, an overview shot of the tunnel entrance to staging. I closed the gap in the base board along the tracks, placed some support columns, and added the retaining wall next to the background. The retaining wall is salvaged from my Dad's dismanteled layout, and still needs to get painted. There's a connector for track power for the Emsingen yard tracks, which will be hidden under the boiler house of Werner & Soehne later.

Breakfast

Ballast

Before ...

... and After.

Ballasting is not exactly one of my favorite tasks on the railroad. However, I find it gets your mind off things, and just like placing bushes and shrubs, has somewhat meditative properties.

Yep. That's one evening spent on about 3 feet of track.

Some minor progress

This weekend I continued to work on the bridge:

I added some Scuptamold rocks around the abutments, painted the bridge, and blended colors into the surrounding scenery. I feel like I have a bit too much gray on the layout at the moment and will need to balance that with a lot more green...

Since I'm about to close up the area around the tunnel portals to staging, I had to ballast the second track while I still can get there somewhat easily. I obviously didn't do such a great job on the first track in the front two years ago, since the ballast is coming loose along the embankment. 

"Bridge" installed

Tonight I glued the railing to the bridge. The railing is anchored in small holes I drilled into the stripwood that runs across the top. One hole went into my finger, but that's another story. Next I taped the bridge to the sub-roadbed and the track, applied a generous amount Scuptamold to build up the surrounding rock, and cement the bridge in place permanently. Next up: Painting the whole thing.

It's somewhat hard to see in the photo, but looks like the glue I used to stick the styrene sheet to the foam ate into the foam, and formed indents on the outside. Oh well, it's an old bridge...

Solar Tornado

And for a change from my usual subjects, this is quite impressive...

Hanging "bridge"

Covering up another planning mistake...

When I built Talheim station I built a road underpass into the station board off layout. That worked and looked great until I started building the curve leading up to Emsingen. It had its widest point exactly where it met the portal of the road underpass. Whoops!

As I built up the basic scenery I modeled a rock "cave" at that point, the road runs under the railroad, and for the longest time I had a cardboard cut-out indicating where the bridge would go.

As the scenery is moving closer to that section of track, it's time to fix that.

Building the bridge wall

First test fit

 I used a 20 year old Faller plastic "build your own tunnel portal" strip, and a Heki foam wall sheet, eyeballed the length of the strip and cut a mostly balanced opening into the foam sheet. Then fitted the strip into the arch. There's a piece of styrene backing the foam for added stability. I used push pins on my work bench to hold the pieces together while the glue dries

I should have cut the sides of the foam sheet an angle instead of vertically to ease the transition into the surrounding terrain. The rather harsh edge I have now will need to be fixed and hidden away with Scuptamold, bushes, and ground cover at a later time.

The Grassinator

I had this on my to-do list for a long time now...

The Grassinator

Static grass is pretty darn cool, but I lacked the tool to apply static grass on the layout. I picked up a Noch static grass shaker bottle, and it kind of works. However, the grass would not really stand on ends, but rather be a jumbled mess.

Last summer I bought an electric fly swatter. These are nifty little devices that typically look like a small tennis racket. They generate a high voltage load which zaps insects when you hit them with the metal screen in the paddle. Using that, today I finally built ... The Grassinator.

Construction is extremely simple: Disassemble the fly swatter, remove paddle, cut cables to the paddle, hot glue a metal sieve in place of paddle, connect one cable to sieve, connect other cable to an alligator clamp. Done.

To apply static grass, drive a nail into the scenery, generously apply scenery glue or matte medium, add some static grass into sieve, clip alligator clamp to nail, turn on Grassinator, gently shake the Grassinator while holding it closely above the ground, and the static grass fibers will fall through the sieve. Static electricity between the wet glue and the sieve will make them stand on their ends (well, mostly, this Grasinator is not super strong).

Here's what the result looks like, with the glue still wet. I'm using a base of fine ground foam before applying the static grass to give a bit more body. 

Approach to Hochwaldtunnel with static grass hills

No modelling this weekend ...

... but the tax return is done. Yay.

I'm starting to see a pattern on my "taxes are done" posts. It seems, I'm mostly doing my taxes a few weeks before the deadline. Unless I'm really motivated.

There's always a First Time ...

This week it was:

Since we got to Heavenly too late for the morning lessons, I toyed around on a hill for a couple hours before lunch under supervision of Dave, and then spent the afternoon with the Heavenly ski instructor.

Since there were only four people in the group to start with, and two of them gave up halfway through the lesson, and the third one had to leave early, and the instructor met an instructor friend, who joined us for the last hour or so, I got private coaching from two instructors for the second half of the lesson. That was very nice, and more than made up for the slow pace of the first 90 minutes.

For those of you familiar with Heavenly:
I spent most of my time in the beginner's area near the tubing hill, and at the end took the Big Easy Chair Lift to Easy Street a few times until the lift closed.
