Hi Luke -- I want both your truck AND your Nixie Tube speedometer -- I'll trade you for my wife's two stupid dogs (LOL)

So, how's all that transfer coming along?  How much longer before all the APP content lands?

I'm doing my best, but I'm just one man (sob sob) ... take pity!

Why not an APP archive instead?

@Max "but I'm just one man (sob sob)... take pity!"

Instead of you manually re-entering the APP articles one at a time, it would be far faster, and considerably less Sisyphean, for your Vogon Overlords at UBM to make the ORIGINAL SITE available AS AN ARCHIVE, INCLUDING BOTH THE ORIGINAL ARTICLES AND THE USER COMMENTS.

-Brian

p.s.

Preferably along with Scope Junction and other user-content-driven websites that the UBM division of the Vogon Constructor Fleet has previously demolished.

p.p.s.

I would link to my original post on Programmable Planet stating essentially the same as above, but I can't BECAUSE THE BLOODY WEBSITE IS GONE.

As best I recall, my closing question went something like this:

When next you dine with those who "wear the UBM undergarments of authority", ask them this:

How long do they think technically savvy users will continue to generate content, for free, for a publisher who demolishes the resulting websites on short notice with no publicly accessible archive?

Are you calling me a sissy? :-)

I can tell you went to a good college that taught English how she is spoke :-)

Not much in the way of mandatory Greek literature at a school where the hockey team is called the Engineers :)

We learned FORTRAN and steam tables and climbed granite steps uphill to class both ways in the snow.

You were lucky! We used to dream of having granite steps...

Max,

 

Your neck isn't red enough to own this truck! If it was you would have offered your wife and two stupid dogs. 

 

Damn country is goin' ta hell.

Hey Luke,

Great project idea, however, I'd simply make use of a cheap Arduino (ebay) and the GPS module from Adafruit for $40.  Then drive BCD out of the Arduino pins to your Nixie tubes.  You'll only need 4 pins per tube for the BCD control.

Ah, but then I see you may *want* to do this in an FPGA, so good luck!

Cheers    -- Mike

What about accuracy?

Nice project.

How will the system behave when the GPS signals are noisy or inaccurate?

The resolution of such cheap GPS receivers are normally at 3 to 5m. Can it really identify a sharp corner especially when the signals are weak? If so what are the design techniques involved?

Why use FPGA instead of a cheap microcontroller?

I know some of these questions will be answered in your next part. But as always it is curiosity that drives us ahead.
