John M got the electronic Citgo sign working again! Just as before, it's not easy to see it unless the lights are dim.
	John P brought in a couple of new bandsaw blades, which was good because it was becoming difficult to tell which edge of the existing blade had the teeth on it. Then he cut a piece of webbing belt with the saw and got the new blade all fuzzy, but the fuzz should come off. One of the guide wheels beside the blade has jammed solid. A new part is needed.
	Bill started nailing down the roadbed in front of the paper mill above Berkmannville.

This shows Progress occurring across WIndsor St, in the former parking lot (much missed by car owners).

Quentin obtained a high-efficiency LED driver suitable for the 1 Watt LEDs we've used to illuminate Berkmannville, as in the April 25 report. It definitely works. (The unit is in the lower left of the picture.) It has a nominal output of 330mA, and the meter shows that it's delivering 327mA. Not bad. An economic issue needs to be addressed. This driver can control 6 LEDs and costs $4.00. A linear driver costs less than $1 if we hand-wire it, but it generates heat. Do we want to buy a lot of these drivers? Do we want to attempt to make our own?

	Recent operation of passenger equipment has demonstrated that Chez Kotok is located too close to the tracks. Rebecca and John M moved it. (Wait for what Mike is doing in the background.)
	John P installed a new lighting fixture to illuminate Berkmannville under the Second Level deck. It consists of 4 1 Watt LEDs on a metal bar.
	The picture really doesn't do justice to the brightness of these lamps.
	Here's a view with all other lights off.
	This picture shows the contrast between the lighted and unlighted areas. We have another 46 LEDs that we can install, but we may choose to keep the lighting dimmer over areas we'd prefer not to emphasize.
	Mike's project for the evening was to install a fourth block card inside the helix (it's the one at the lower left).

	David Lambeth sent a package from the "West Coast Shops".
	He painted the Preiser figures that John P purchased several years ago, and also made a prototype platform canopy with LED lighting underneath.
	Closeup of some of the figures.
	Rebecca did some more scenery.
	Both sides of the track.

	Andy's bridge over F-yard made some Progress.
	Second view of the same.
	John P cut road bed for the paper mill area on the 2nd level.

	The next phase of Level 2 construction required the production of sawdust, which took place out in the hallway in order to make cleanup easier. This is "experienced" plywood.
	After a multi-year lapse, Quentin (supervised by Mike) played with his lighting control box. The objective is to use it for room lighing.
	It produces an interesting waveform.
	This is the effect of a "cool white" LED rope light over Berkmannville.
	The cardboard mockup now sits on plywood.
	Mike and Quentin worked on the spotlights. They're wired through this box.
	New member Rebecca worked on scenery in Berkmannville. She seems to have a good eye for it. Mike's abilities as supervisor were called on yet again.

	We got the two steel supports set to the correct height and extension, and we put a large piece of cardboard across them as a mockup of the first level section of Level 2. This is where Bill is planning a paper mill. He laid out the proposed tracks on the cardboard.
	The predictable problem caused by the upper level (even if it's only made of cardboard) is that it shades the lower level pretty badly.
	David Lambeth's LED rope light helped, but we need more. A discussion of under-deck lighting took place.
	Mike mounted the next two Unistrut sections, in this case both on the same 2x4 post.
	Section 15, formerly made of foam-core board, was remade in plywood. Tracks have been drawn in to connect with the paper mill area.
	It's a large irregular shape, and cutting it made a lot of dust.

	Mike and his dad installed a second Unistrut-Dexion support for the upper level.
	John P mounted a fourth servo for controlling turnouts on Section 14. It's combined with an attachment point for threaded rod support.

	Mike worked on the new upper level structure (here seeming a little exhausted).
	Slotted angle girder at its final height, but maybe needing to be pushed out further.
	The mockup Section 15, with a new bracket in sturdy plywood in front of it.
	The second and third servos are now connected to turnouts in the helix Section 14 area. Because the throwbars are almost in line, the servos are mounted in a "one up one down" arrangement. Note that one long wire is routed through tubing to prevent buckling.
	Another view of the mounting of the servos.

	At long last, the batteries in the door lock died. A dismantling was necessary.
	Experienced operatives performed the task, and the reassembly. No leftover parts were found.
	The first servo has been connected to a turnout in the helix Section 14 area.

	Full moon over the biotech labs.
	We are experimenting with static grass, using a converted electric fly-swatter purchased for a grand 3 dollars, and a tea strainer.
	The strainer has had its handle shortened, and it's attached to a block of wood which can be locked into the fly-swatter.
	The first experimental grass patch.
	Is this stuff standing up?

Very little happened tonight. Here is Eliza's TV truck with a functional electronic package. You can see it in action at our Youtube page
