Digital Life: Mona Lisa in Excel spreadsheet form

mona lisa in excel form.jpgA bit of nonsense that caught my eye over the weekend - the Mona Lisa in Excel spreadsheet form...

No, it has not been manually created, painstaking cell by painstaking cell - which is what Leonardo would have done, were he a data entry clerk using Microsoft software - but by a piece of software called ExcelArt.

Apparently, it can take most of your uimage files - bitmaps, jpegs, GIFs and PNGs - and convert for Excel. Thanks to Techeblog for this one.

Poll: Wireless Comms == Always On?

Netgear DG834G.jpg
It is always slightly disconcerting to find your viewpoint in a small minority, especially when it seems so logical and reasonable... But that's where I find myself over the handling of wireless Net access at home, following a rather random sample of the office.

Putting aside security issues (where I also seem to find myself in a minority with concern over unsecured access), when it comes to powering my Netgear wireless router, it is only turned on when needed and turned off at the end of the evening, if not before.* Is this strange?

So, the question is - do you ever power down your modem / router, or do you leave it permanently on?

An engineer in wonderland - BT Broadband annoyance

 

An Engineer in Wonderland has a new home. You can find this particular entry here. If you wish to leave a comment, please do that on the new blog.

 

Having resisted it for a long time, I have had broadband installed at home.

I thought long and hard about who would supply the service.

Any company with a bad reputation for service or reliability was straight off the list. 

Eventually I whittled it down to a shortlist:

How do you see the split of 8-, 16- and 32-bit business developing in the next 5 years?

You've made recent acquisitions in both touch technology and wireless IP. What are your expectations for these technologies?

An Engineer in Wonderland - Revealing touchscreen review

 

An Engineer in Wonderland has a new home. You can find this particular entry here. If you wish to leave a comment, please do that on the new blog.

 

Take a look the capacitive touch screen test on the website of development firm Moto.

iPhone comes out particularly well - its precision looks as good as a resistive touch screen.

Motorola's Droid does not fair so well.

And there are plenty of examples in between.

All the touch screens look pretty good for handling square touch buttons.

But some of them would be awful for sketching, and pretty bad for dragging and dropping.

An Engineer in Wonderland - Tsunami generator

 

An Engineer in Wonderland has a new home. You can find this particular entry here. If you wish to leave a comment, please do that on the new blog.

 

Tsunami generator.JPGI had assumed that almost everything was simulated in computers these days, but aparently not as the EPSRC (Engineering and Physical Sciences Research Council) has just paid for a wave simulator with real sloshing water.

It seems that a new facility is needed to simulate the dreadful 2004 Boxing Day tsunami.

Photo: Tsunami generator before being lowered into the water. Horizontal baffles stop sloshing inside the tank for a cleaner wave.

In depth - High-brightness LEDs

Check out an interesting feature article we have uploaded to the site, concerning High-brightness LED lifetimes - HB-LED lifetimes affected by weak links

The main points to note are:
  • Properly chosen capacitors can support the long life and reliability that SSL (solid-state-lighting) products require.
  • Heat is the main culprit in decreasing capacitor life.   
  • Aluminum electrolytic, ceramic, and film capacitors all have their place in HB-LED (high-brightness-light-emitting-diode)-driver designs.
The article begins:
