Hong Kong trip postponed.


I was supposed to travel to Hong Kong on Saturday 11th October to attend HKTDC, but I had to pull out due to a foot injury. Now it looks as though that might have been a provident decision, given the current unrest in the area.  Continue reading

Ink-Jet printed PCBs anyone?

I read in Electronics Weekly this week that the boffins over at Georgia Tech, alongside people from Microsoft Research and Tokyo University have developed a method of ‘printing’ circuit boards using a standard off the shelf ink-jet printer.

They basically took an empty ink cartridge and filled with an electrically conductive ink made with ‘silver nano particles’. When you print the circuit onto paper, the tracks are electrically conductive.

The main issue really is that it’s pretty hard to actually mount components onto paper, so they have to be glued on with electrically conductive paste. This is OK for basic proof of concept stuff, but it looks like we are still a way off from having truly functional printed-at-home circuit boards.

You can read the press release at Georgia Tech’s website here.

Books for Electronics Engineers


Here’s a list of books I recommend for electronics engineers. If you have any further suggestions, post them in the comments and I’ll be happy to add them.

First, for a good grounding in electronics theory, circuit analysis, engineering maths for electronics and low level study, try this:
Introductory Circuit Analysis by Robert L. Boylestad. This text is often used in university undergraduate degree courses.

Next, if you are ever doing any analog audio electronics, you can’t go wrong with these books from Douglas Self:


For Microcontrollers and Arduino:

Or for details of the Cypress PSoC range of devices, try this:
