Robots to learn something from the fish eating bat

Posted on

An amazing application of a colony animals solution to a search for food could revolutionise the way robots communicate. Israeli researcher Yossi Yovel leads the team at Bat Lab for Neuro Ecology at Tel Aviv University. His research into communication has focussed specifically on the Mexican fish eating bat, native to California. The large range […]

UK electronics industry: the new frontier

Posted on

Recent feats of engineering, like the launch of the Philae landing craft which touched down on a comet last November, demonstrate that the UK has an important part to play in the global electronics industry. Production shops based in the UK have earned a strong reputation, making top quality components in technical and specialised industries. […]


What is PCB pooling?

Posted on

Order pooling can help small scale or specialised operations save money on their PCB and prototype costs by sharing fabrication panel space, tools and machine set-ups. The reasoning behind this cost saving is quite simple and can be best illustrated with an example: If Company A requires one 5×3.1 boards and Company B requires one […]


Hi5’s 2014 investment ends with black hole (machine!)

Posted on

2014 saw us bid a fond farewell to our venerable Resco Black Hole machine and welcome our new improved machine, manufactured by Lantronic of Holland. What is the Black Hole process? In order to make the holes in a printed circuit board conductive (prior to the copper plating stage), we need to apply a microscopically […]


Flexible PCBs move forward

Posted on

Printed circuit boards (PCBs) are the heart and heartbeat of all electronic devices.  Developed principally after WWII, we are all familiar with the exponential development in PCB technology in the following years, and the oft-quoted pub statistic that the electronics in the spaceship that first landed man on the moon are now found in most […]


8 tips for PCB designers

Posted on

In the 21st Century, electronic equipment can perform an incredible array of tasks, from automatically recording Antiques Roadshow… to automatically hovering round your feet as you watch it.  However, at the heart of any piece of electronic equipment is its circuit board… its neural wiring.  And if you get that wrong, you may find your […]


How to protect your PCB

Posted on

PCB design has come on a great deal In recent years and circuit boards can now be incredibly resilient (and in fact, as we have noted elsewhere on the site, even manufactured in bendable material).  Despite that, there is still one thing all designers need to bear in mind when it comes to their circuit […]


Energy Saving LEDs Win Nobel Prize

Posted on

Last week, the most prestigious award in the world of science was presented to three scientists for an invention that’s bringing light to even the darkest places in the world. On first impressions, the humble blue light emitting diodes (or LED for short) may not strike you as the most impressive of inventions. But the […]


What you need to know about RoHS

Posted on

Firstly, the basics.  RoHS stands for “Restriction of Hazardous Substances,” the culprits in question being such materials as mercury, lead, cadmium, hexavalent chromium, polybrominated diphenyl ether flame-retardants and polybrominated biphenyl. The notion behind RoHS is to reduce the use of these potentially toxic chemicals in electronic items. Initially aimed at consumer/household electronics, the net was […]
