Happy New Year - get things in perspective

scale of the universe.jpgHappy New Year everyone!

How about this for an impressive InfoGraphic to start the year? The only response is, Wow! View Scale of the Universe and journey from atom to solar system...

Thanks to Sue P. for flagging it, one to file under the Digital Life category.

It was developed by Cary Huang at htwins. Check it out! >>

An Engineer in Wonderland - DVMs from Santa's workshop

 

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.

 

LittleDVMpic.JPGI like to make at least one present for someone at Christmas.

This time it was little pocket DVMs for those gathered around the Christmas tree that maintain their own cars and motorbikes.

A little time consuming, but the result was three happy relatives.

Only Connect: 3M Twin Axial Cable

3M Twin Axial Cable 1.jpgWelcome to another post in the series by Nick Locke, of Nicab Ltd, who has over 15 years experience in the electronics manufacturing industry specialising in interconnection cable assembly.

For my fist blog of the year I thought I'd start with a new product innovation from 3M.  For those of you who are into high-speed data then this is for you!

The 3M Internal Twin Axial Ribbon Cable SL8800 Series is a new ultra low-profile, high-speed, high signal density cable. The products in the SL8800 Series are only the first of a new family of high-performance cables from 3M.

The information in the 3M tech specs state the SL8800 Cable Series is a longitudinally shielded cable construction and is made to exacting tolerances. The cable suffers little to no resonance or "suck out," where traditionally spiral wrapped twin axial cables exhibit an enormous loss of signal at a particular range of frequency.

Elektra Awards 2011 in photo form

Elektra Awards 2011 - winners Elektra Awards 2011 - attendees Just a quick post to flag we have updated the Photo Galleries index with Elektra Awards 2011 content.

The gallery of attendees went live last year but the gallery of winners has just gone live, as well. Look out for more pictures of the winners in the coming issue of the magazine, too.

Just in case you are curious, the official route maps for HS2 are on the Department for Transport website.

Turn's out that there is a lot of existing rail infrastructure in North London that I have never heard of.

Updated: The market capitalisation of the UK electronics industry

EW Shares Index screenshot.jpgUpdated 19/1/2012: Did I say £18bn? Make that £800bn! Thanks to Ciaran for pointing out the omission of CSR (!) and there is also e2v and BAE Systems to add to the mix. They make a big difference! Hopefully we have now reached a good set working set for the future.

Is the UK electronics sector an £18bn £800bn industry? That is, based on the market capitalisation of the major listed companies...

Playing around with Google Docs spreadsheets, dipping my toe into data journalism as it were, I've put together something that may prove useful over the coming months or years. We live in interesting times and I thought it would be worthwhile to try and create a sort of Electroincs Weekly Index based on the share value of publicly quoted UK electronics companies...

Only Connect: Quality of workmanship and value of UK Manufactured

Welcome to another post in the series by Nick Locke, of Nicab Ltd, who has over 15 years experience in the electronics manufacturing industry specialising in interconnection cable assembly.

Having recently completed another round of IPC Training I am furthermore reminded that we are really very good at what we do in the UK Electronics industry.

I am not saying this to "blow my own trumpet" but rather that we as a whole are very good.  What's more, talking to the trainer our standards of workmanship seem to be on a real high with more companies choosing to up-skill and focus on high-value mission critical product markets.

An Engineer in Wonderland - Op amp needed for a current source

 

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.

 

constant current 122.JPGI was pondering a simple way with a low drop-out voltage to power a grounded LED from a grounded supercapacitor. Something that would be tolerant of the LED being powered from elsewhere when the capacitor is empty.

The easiest option is to use a resistor, but this will mean brightness is dependent on capacitor voltage.

A complicated way, which could deliver maximum efficiency and maximum power extraction, is to implement a buck/boost converter.

Picture Gallery - Spy-in-the-sky circuit-board glider

circuit board glider 100.jpgI'm pleased to flag another new photo gallery, this time concerning a spy glider that uses circuit boards for wings... See Picture Gallery - Spy-in-the-sky circuit-board glider

The US Navy has tested a spy-in-the-sky glider 30cm across made from circuit boards. Its lack of a motor and small size make it nearly undetectable in flight, says the US Naval Research Laboratory...

Only Connect: On education in electronics

han yellock.jpgWelcome to another post in the series by Nick Locke, of Nicab Ltd, who has over 15 years experience in the electronics manufacturing industry specialising in interconnection cable assembly.

They say that if you always run your car on empty eventually it wall cause damage to the engine and cost you more in the long term, I believe it is the same for your mind.   

If we only invest in the minimum to get by we will mostly just get by.  However, if we constantly keep our minds topped up we will run in peak performance which leads to long term happiness, and isn't that what we all want?

It's not easy, it takes hard work and more effort but then anything worth having is always harder to gain.  If you work in a highly technical industry such as ours it is well worth taking the opportunity to improve your knowledge, and it is possible. After all, learning about something your are interested in is always easier.

An Engineer in Wonderland - How wings really lift

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.

The University said: 

It's one of the most tenacious myths in physics and it frustrates aerodynamicists the world over.

Only Connect: UL markings

Welcome to another post in the series by Nick Locke, of Nicab Ltd, who has over 15 years experience in the electronics manufacturing industry specialising in interconnection cable assembly.

In this week's blog post I am going to show you how easy it is to understand UL ratings on Cable.  

This is often an area of confusion as we have the BS Standard, CSA (Canadian Standards Association), and (Underwriters Laboratories) ratings - it's hard to know where to start or which standard to adopt.

For many the default standard of choice is the UL for cable & wire. The main reason for this is the international association of the standard. Pretty much everywhere in the world recognises the standard. What's more, the leading brands such as Belden & Alpha use UL ratings as standard.
