Ahh... excellent! Though my Grandmother would be chasing those workers down with a broom for their light washes and heavy wipes...

Hi Volker
looks like it needs a feminine touch love the soap dispencer.

Hauk's post of a picture was a real treat and inspiration to go ahead.

To bring that to light:






















Some daylight shots to follow by chance to show lampshade installation and real and fake wiring. I needed to finish that before detailing all the remaining wiring starting from the electrical board.

Cheers,
Volker

Fantastic! Are the scale lamps the only source of light?

Having worked in a machine shop while in college it looks great, however the floor under the sink is too clean and there needs to be the towel the lazy worker threw on the floor under it.  Have you risen to the challenge of nailing the smells down yet?

Not bad. -- Russ

Hauk,

yes, they are. All warm white 3,3V max. 25mA leds with printed bulbs glued to them. I use constant current sources instead of resistors because for a long time I wasn't sure which voltage I would use in the end. The ccs work from 4V up to 24V DC, depending on how many leds you connect in series. There's a 2 gauge standard in german of 24 V, but the ccs get a bit hot with that and I think I'll end up with some 15 or 16 V.

Cheers,
Volker

Lampshades are 3D printed parts. I didn't want to have any visible power supply, that doesn't match the prototype's appearance. So the lampshades needed to have the same cable run.




It was a bit tricky to pull the 0.15 mm enameled copper wire through the lateral 0.6 mm holes, but a sewing needle worked fine. All led's are replacable via the Bi-Pin sockets, which are soldered to the wires and then pressed into the lampshade hulls. Printed bulbs are glued to the leds.










The first and last lamp of one row has a supply cable.




The following ones are connected via tubes; it is 0.6 mm brass tube with enameled copper wire inside.




I was lacking an eighth lampshade and so decided to have another, rather simple one at the boiler area. I was so euphoric about that solution that I forgot to make that removable. There would only one cable be necessary at the prototype and so the hook serves as second pole for power supply.







All lamps are mounted with those hooked hangers, that are fixed to the roof beams with a plate and two screw imitations. Note the enameled copper wire running from the fixture along the beam's edge to the shrink tubing insulated cable connection.




Roof, wall and floor of the building need to stay separate, so power supply leeds via pins from floor to wall and then via a screw/brass nut combination to the ridge pole, where the constant current resources are installed.








Cheers,
Volker

See how simple and easy that was? Anyone could have done it. -- ssuR

[Ray Dunakin]

It looks amazing, and your wiring and lights are fantastic!

[Hauk]

Great tutorial for making lamps.
As I need 14 similiar lamps for my own project, this was just what the doctor ordered.

[SandiaPaul]

Outstanding...

[Bill Gill]

Terrific light fixtures and great way to disguise the wiring!

[Sami]

Wonderful job !

[Hydrostat]

Thanks, Russ, Ray, Hauk, Paul, bill and Sami.

I started work at the traveling trolley:










Paper strips prevent rope to slid off the roller flanges during construction. They are going to be removed when crane is finally mounted with strong tnesion on the ropes to have them running straight.











More details and coloring of the guide rail to come. 

Cheers,
Volker
