First thing I saw this morning when entering my workspace [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-2116b937-1d70-4751-8670-b8026ba12f44/6175.contentimage_5F00_930.png:16:16]:

[View:/resized-image/__size/620x302/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-2116b937-1d70-4751-8670-b8026ba12f44/0317.contentimage_5F00_184514.jpg:620:302]

In the mean time I also fixed a software error.

The line:

blog_counts = views * 100 + likes;

Showed the expected value (075006), although the multiplication was wrongly set at 100 in stead of 1000.

How can that be?

The answer is that javascript does automatically type conversions (https://www.w3schools.com/js/js_type_conversion.asp ). Both views and likes are string values. multiplication of views with 100 makes it a number, but likes still is a string, so what we get here is 7500 + "6", which makes blog_counts a string again "75006".

Solution is to convert likes to a number by multiplying it by 1:

blog_counts = views * 1000 + likes * 1;

Now blog_count will become the number 75000 + 6 = 75006, which is right.

Great post.

The web scraping lends itself to so much.

I'm worried about your Rain Volume in the last 3Hr.

Here in Fiordland they measure annual rainfall in metres, so I hope your figure isn't mm. [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-2116b937-1d70-4751-8670-b8026ba12f44/contentimage_5F00_3.png:16:16]

I agree, the vintage nixie tubes are just too cool.

Awesome post, this has got me thinking. I could do something similar using python-beautifulsoup, but looks like time is not on my side. Maybe, I will try this after the challenge. Thanks - Carmelito

Great post! I love always more the nixies [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-2116b937-1d70-4751-8670-b8026ba12f44/contentimage_5F00_1.png:16:16]

Take a look, what do you think to a hack to this '80s train station clock (don't ask me how I got it) with some more tech info with a set of nixies in the middle?

Perhaps the Edison could calculate pi and you could scroll it across the display?
