Software and LEDs

These are the beasty linux boxes that I have to develop for for a living, neato :-)

A whole whack of them all together.
These are some of the beasties I work with, they are much friendlier than the Linux boxes!

In case you are wondering, the LCD looking bits are actually OLEDs, and the glowing buttons are really multi-colored, the illumination uses PWM'd LEDs to produce a few basic variations on red and green.

Microcontroller hackingness stuffness

It's nothing great really, but since arriving in the UK, I've posted a little about resuming a hobby in electronics. One thing that has happened to electronics since I as in school is that CAD and digital electronics have become affordable areas to hack about in.

For instance, if you have a very fast micro-controller (which is a CPU with some peripherals), and I say fast, because micros are not fast, they are intentionally slow because they are not supposed to be used for applications that use lots of data. A CPU is different, it typically has minimal peripheral support and maximal memory bus support, and generally uses 100x more juice. OK, back onto topic - a fast enough micro can actually simulate lots of things you would have done in a basic analog circuit, but at a lower component-count. Enter Atmel AVR. I could have opted for PIC chips, but something in me always opts for the fresh or the underdog over going with the stale or the old leaders.

Here is where it starts.
3 AA batteries to run it, some optional transistors and you have a moving display.

Net Noobs

OK, so you go to a website that offers a callback service - and they ask you for a email address, why does anyone need my email address? I am just so confused by people's eagerness to offer you crapinstead of service sometimes. unfortunately for auto-glazing (not autoglass), they will be sending mails to I know it's cruel, but somebody in lapland needs to tell dumb internet citizens where to get off. After submitting a form and getting no response, I can only assume they are thinking it's a prank post. Seriously now?

How long is a M$ minute?

Once again the Desktop clean-up wizard appears, it seems to wake up every 2 months, and then has the cheek to say that a shortcut that I last used 4 months ago, has never been used.

It seems the M$ definition of 'never' is totally off the wall, and today I am disabling the silly program. I see it has been striped from Vista, I can only guess that the OS is either showing it's age or we are forgetting that how to go about making a system easier to use for beginners, yet powerful in the hands of the advanced user is actually not do-able without a "I am a noob" switch. Am I just blind to all things PC?

If you look under your desktop properties, there is a tickbox hidden away there. just clear it to stop the wizard.
