Cyber security flaws can kill

Internet of Things is going to affect more and more our everyday life. All kinds of devices have got or are getting network connectivity. It seems that the IoE is inevitable. We must expect a rapidly growing number of devices to be rendered “smart” and thence to become interconnected. Internet of Everything’ (IoE) – the

Fluorescent lamp fire danger

A fluorescent lamp or a fluorescent tube is a low pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. A fluorescent lamps are widely used because they convert electrical energy into useful light much more efficiently than incandescent lamps (The luminous efficacy can exceed 100 lumens per watt). They are widely used in

Electrical safety

Yesterday I passed SFS6002 electrical safety course and got SFS 6002 käytännössä book. SFS 6002 electrical safety training is for all electrical work in Finland engaged in compulsory education, which must be renewed every five years. Now I know somewhat more than before on electrical safety related to electrical installations. SFS6002 is a Finnish standard

Electronics lab electrical power

Here are some tips how to arrange electrical power distribution on a small electrical lab (for example home lab). Grounded power outlet: The power that comes to your electrical lab should be grounded for your safety. Most everyone has 3-prong electrical outlets in their homes, with the third prong being called the “ground.” Extension cords

Event Safety Guides

Safety is important when arranging events. And there are a lot of things to consider to make the event safe for everybody (I know from experience from several event I have been working with). Control Geek blog writes about US Event Safety Alliance Document in Public Review. The Event Safety Alliance is a group of

Fused multimeter probes

This is my second product test on Free Product Road Testing program by Farnell. This time the tested product is fused test leads for multimeter (Farnell Number: 428-4276). Why Fused Leads? You might ask why test leads need be fused. Trust me there are situations where this is a really good idea. Maintenance of electrical

Multimeter safety

Safety must always remain priority number one when doing measurements with multimeters. Working safely, while making electrical measurements, is not rocket science. It’s a simple combination of careful planning, safe practices and using the right tools in the right way. The more voltage and current is present in the circuit, more careful you have to

Controlling dangerous things safely

Fire When Ready – A Pyro-Electric Safety Primer is a great document on issues around controlling dangerous things electrically. The document tells the techniques used on pyro/fireworks electrical control. Quite similar practices are used in other control applications where potentially dangerous things are controlled using electrical circuits or electronics.
