Put all the signs on.
In beautiful polished brass.
Looks really cool now.

With the signs a bit off the wood, there is a nice shadow...

They fit...
All of them.
It is still very big.
But then again.
If you decide to make the first real time analogue planetarium.
You better expect it to be big.

Now I need a new house.
A sort of castle.

Marcel Z.

The signs.
In brass.
I made the program...

Then Marcel laughed at me.

After a minor correction they were ready to be cut out.

With a 5.2Kw MONSTER of a laser...
Kind of cool (well hot actually) though.
All of them on a heap after a first polish...
They look absolutely great.
Funny how the date of the exhibition approaches faster and faster.
Time was supposed to be linear, something I wrote in another part of the blog.
Not so, it seems...
Must be because I make clocks.....

La Nuit de la Science

The Planetarium will be exhibited during the Nuit de la Science in Geneva.
The pendulum clock too!!

Just a couple of days.
For all of you to see it.
For real.
The stand is ready.

The box too....

You can not really overlook it.
It is still very very big...

The box...
Way too big..
I drew it.
Size 1 to 1.
Stuck it on the wall.
Way, way too big...
So, I scaled it down as much as possible.
The meters are really BIG.
But, it looks much better like this.
Slimmer and smoother too.
Made the signs smaller too.
They were just huge.
Going to cut them out of brass.
With the box in oak.
And with a bit of luck you'll all be able to see it soon.

The planets.

Where are they?
What time is it for the Jovians?
See at a glance where our planets are.

Where in their orbit around the sun....
Where they are in their own day...
Can be done I think.
Made some sketches years ago.

Pluto is concidered a planet, I never did!

OOOOF, back to 8 planets.

Still need 20!! meters.
Then finally found them.
All 20 of them, all the same.
All in bakelite, exactly what's needed.

They are the indicators.
Drew it all up in a cad system...
Top row: our own time system,
days devided in hours
hours devided in minutes
minutes devided in seconds..
Then per planet:
the planetary day, also called sidereal day
And its sidereal year...
That needs some serious slow counting...
146 Earth's years for one on Neptune...
I'll never even see the needle move!
