A document on how the Divergence Meter came to be!
*Drum Rolls* *Cheers* YES it’s finally complete :’) THE DIVERGENCE METER IS COMPLETE !!! It took me a long time, it took me a lot of effort, it also caused me a lot of headaches but hey its complete!!!! Really awesome indeed, though I still have to tweak it a bit in the software, somehow release 0.1.0a of the software uses up a whopping 6KB out of 8KB of program space, I really hope to optimize the code and make the world line rolling much more visually accurate, otherwise it’s really awesome to look at especially at night 😀 the way nixie tubes display numbers gives that really special retro feeling yet it gives a futuristic feeling at the same time.
Now for some power consumption reports, well so far I’ve only had the thing on batteries with the longest duration of 2 hours but according to my estimations, measurements and fooling around(writing it down makes it science ;D ), I’ve found that it should run for around 4 hours on the lowest brightness settings and 11 hours on the highest. One thing I did though design in an “adaptive brightness” feature into the thing. Basically it uses an LDR (Light Dependent Resistor) and the device measures the environments brightness, when it’s dark it turns the display darker to save power and when it’s bright it turns up the display to make it easier to see.
All the circuit boards are finally assembled!!! And I only can say THEY WORK!!! 😀 Though of course there are some parts of the design which make me think about my design skills :/ well pictures first!
