Connectors get used in pretty much every environment on the planet. Off the planet, too, when you think about it. There are still some connectors on the moon, and I think Voyager probably
Having attended several technology shows at the beginning of the year, it’s clear to me that multicore is finally really happening, and it’s happening fast.
RS’ free of charge IDf-to-Collada converter allows EDA tools to connect with the popular Google SketchUp 3D Modelling package. Ever had a design that did not quite fit the mould? You have laid out t
An electronics or embedded engineer should not limit themselves to writing firmware. Having thorough knowledge on hardware empowers the designer to understand what is happening and take the right path
Many of us sit and complain about how well products work, point out there issues and bad point but few spend time doing something about it. In this review I look at just such a product, designed by en
As I wrote this blog Raspberry Pi exploded on the scene taking everyone by surprise with the sheer volume of people wanting to buy it. Many readers will have to wait a while to get their hands on one so why not use the time to investigate rather more interesting projects than just writing games? How about giving a humanoid walking robot some Artificial Intelligence…
Will USB 3.0 ring the death knell for slower serial interfaces?USB 3.0 has arrived; at over 10 times faster than USB 2.0 it promises to provide quicker file transfer between enabled devices, feeding c
There has been a lot of buzz and stories going around about the first micro to have FRAM (Ferroelectric memory). FRAM has been talk about it not only here on DesignSpark but on element14 and was comme
The Raspberry Pi has been a cause of such excitement that individuals, open source projects and companies alike have been developing complementary hardware and software.
From the release of the first PC by IBM back in 1981, engineers have found more and more creative ways of using this system architecture. True, many things have changed over the years, but execu
I was very excited some time back when I got my hand on the new DE2 Development and Education Board from Terasic. Following my review of the DE0-nano back in July last year I have been playing with lo
A major highlight of a week of activity at the Sci-Fi London festival was the Horizon Spectrum event at the BFI Southbank celebrating 30 years of the Sinclair Spectrum 'home' computer. I attended the
While in the previous post we describe the main idea of the HD Audio together with the DAC selection and the first considerations, now it is time to move to the actual design. We are going to use the
So, connectivity... Where would we be without it? Well, obviously some place else. But as luck would have it, we are able to communicate and we can communicate with our ICs. In fact we're having loa
An Internet connection would be a valuable addition to many projects, but often designers are put off by the complexities involved. The ‘NetWorker’, which consists of a small printed circuit board
As the title suggests, this post is all about the creation of a multipurpose display board, powered by an mbed. The display board has exposes many of the GPIO functions of mbed and so can be used for
Following the Part 1 and 2, it is time for the last hardware oriented post of this blog series. Future blog posts will follow covering the software aspects of the project with some libraries and refer
The RS Embedded Development Platform offers an alternative path to the engineering prototype stage of a project allowing quick and easy changes of processor at the time of initial design or for upgrad
So last week if you have been following me on Twitter you will have seen I attended the National Electronics Week (aka NEW). So what did I see and who did I meet? Was it worth the 3 hour drive and
In the post this morning I received the latest product newsletter from connector manufacturer Molex. In amongst a plethora of new designs I found an announcement about the latest FPC connector.F
The Raspberry Pi (aka Raspi) was released back at the end of February but here we are weeks later with no real hardware. We engineers are only interested in the guts of this product.
In Part III, we discussed about how electro-surgery is performed. However, role of microcontrollers in electro-surgery was not mentioned which we shall complete here. Microcontrollers are used in ESUs
Sometimes you can get excited about a Dev Kit before you even switch it on, but can the Leaflabs Maple Board live up to my exportation's or will this just be another STM32 fail? So this last few weeks
Introduction The requirement was to add a digital readout to an otherwise manually bend roller machine so that we could accurately monitor the amount of material fed into the machine. Th
There was a time when deciding which microprocessor to use for a new project was pretty easy: there weren’t that many to choose from. Who remembers the Intel 8080, Motorola 6800 or the CBM 6502? The

A few weeks back I a received the mbed dev kit from RS (Part No.703-9238), but it was only today that I got a gap in my work schedule to play with it.
Open source techniques are being employed in the development and provision of access to an increasingly diverse range of technologies. In this article we’ll take a look at two comprehensive open sou
This post is not about Raspberry Pi. Sorry about that; I thought I'd take a break from all that heady stuff about HD graphics and ARM processors to look at a similar sized and priced beginners' computer board, but located towards the Arduino end of the processor power spectrum. It comes as a kit of parts and you have to solder it together yourself.
Unmanned aerial vehicle (UAV) technology is becoming increasingly affordable, and when combined with low cost wireless sensor networks and computer vision opens up exciting possibilities for use in di
I’ve noticed an interesting trend recently. Forgive my lack of awareness if this has all been said before, but here it is: microcontroller chip manufacturers are making/supporting some very cheap development kits nowadays.
Like my colleague at RS, I had a chance to play with one of the first Raspberry Pi boards in the UK. My remit was to see how easy it is for someone unfamiliar with Linux to get a system working.
I was fortunate enough to receive a Raspberry Pi board for review (Thanks, DesignSpark!) a couple of days ago and I have been playing with it pretty much non-stop ever since. (More photos availab

Last month Nat Morris built a Twitter-controlled feeder for his dog, Toby. In the first five days of this being online it was being used by a group consisting of friends and family. But after national
LED LowdownLED is nowadays considered to be a mainstream lighting technology. Hugh King of Thorn Lighting on everything you ever wanted to know about LED but were afraid to ask.
Texas Instruments have recently launched a new range of ARM-core microcontrollers called Hercules. They contain redundant circuits to detect and deal with faults when used in safety-critical applications. Specifically, two Cortex R4F cores run a common program in lockstep and a comparator unit makes sure they produce the same outputs.
In a previous eTech article we discussed how the high level power architecture in complex multi-rail power systems can have a strong influence on product energy use. This article builds on the initial
