EMC testing

Does my product need a CE-mark?

Probably. By applying the CE-mark to a product, the manufacturer or importer indicates that the product meets all applicable EU regulations—mainly on end-user health and safety, but also on energy and material efficiency.

Many categories of products require CE-marking before they can be placed on the market: These include medical devices, electrical and electronic equipment, machinery, toys, pressure equipment and many others. They specifically exclude food, pharmaceuticals and chemicals. The European Commission (EC) has published the “blue guide”, which offers excellent if very wordy guidance.

If it finds you eat too fast it will vibrate and flash to urge you to take it slow.

Easy prototyping with mbed

Since I attended an introductory workshop a few months ago I have used the mbed module and online IDE/compiler to whip up a number of prototypes.

I’ve been very impressed with how easy it has been to create a working system in very little time. The mbed module is based on the NXP LPC1768 chip (ARM Cortex-M3 32-bit processor) and has plenty of processing power for most applications I can see coming my way.
