...And this is the crux of "Systems Engineering"

Total cost of a system (including rework and repair) over its life is determined by the choices you make at the very beginning of the design.

 

The idea is to very carefully consider the design choices before going forward, understand the requirements, ensure all these things are really what you want to have, and then take *very* careful aim at your foot before pulling the trigger.

 

(I'm a systems engineer these days)

Max, I think at least 10 very tighly packed equipment housing that I have produced over the years have suffered from a very drastic gotcha.

How to get the magic inducing agent in the box.

I seem never to learn but I build the electronics to fit the box and test with a bench power supply and then find I have forgotten to allow any space to mount a power supply in the box or even leave enough space for a power connector to the box.

It seems to be the ultimate peril for Crusty

Looking forward to the completion of this project and I know that the first test song, the "Beta Song", will be Xanadu.  "A million lights [apropos] are dancing and there you are, a shooting star".  :)

I love the 'ye olde' cabinet look!

Do you have any plans for the LED colours? A more mellow colour palette would fit well with the brass finishing but I'm not that good with colour combinations to make suggestions :P

Max,

that's a brilliant story - positively Shakespearean in fact (as in a Comedy of Errors). And I can feel myself and a lot of others who read this wincing at the familiarity of it...

But the end result looks spectacular and I can't wait to see the fruits of your labours after Christmas - go and have a pint or two of mead and let us know the results!

 

Cheers,

Paul.

In terms of making mistakes, I've been known to say that I have the Midas touch - everything I touch turns into a muffler.

What about getting the router out again and routing 1/16" of material such that each channel is surrounded by a 1/16" deep channel? Then you could use the threaded thingamabobs instead of glue.

It's just one more service I offer LOL

Max. all you have done here is proved two fundamental laws:

1. Anything that can do wrong, will go wrong (Sod's law or Murphy's law)

2. The first 90% of a job takes 90% of the time.  The last 10% of the job takes the OTHER 90% of the time (This one does not have a name, though I'd be pleased to call it Ashton's law....I just call it the 90% principle)

Aside from anything else, it's always pleasing to note that I am not the only one affected by these laws.... :-)
