Who am I ?


Hello, I am Richard Hoogeveen and welcome on my site. I live in the Netherlands, Europe.

From childhood I have been busy with electronics.

I studied airplane electronics and technology at the Anthony Fokkerschool in The Hague. A highly regarded school that delivered well qualified people mainly to the aircraft industry.


I became a trainee at a company that just started to develop electronics for telecommunication purposes and for the measurement and protection of high voltage networks throughout the province South Holland of the Netherlands (grid). After a year as a trainee I was permanently accepted into a job. I followed many other technical courses and we were allowed to work with al kind of productions and development processes.


This could be CPLD/FPGA chip designs, pcb design, from digital and analogue simulation to operating pick and place machines for our own production line. We also developed our own system cabinets and performed many measurements on our systems for the desired approvals. The equipment has therefor proved to be very reliable. After about 10 years I decided to switch to IT. I still work in the IT, but never dropped my real profession and I have always continued working with these techniques.

Many of these techniques have now become affordable for the hobby and I have also embraced many new developments like IOT, Raspberry, Arduino but also techniques from the past like tubes and nixies tubes. I have the sometimes difficult feature that I want to master and use all my energy to get something done.

The products and projects you see are therefore the product of many hours of research, designing, testing and building. I like to think out of the box and I like to combine techniques that you will not always see on the market.

Have fun on the site and when you are curious, do not hesitate to contact me.

What started HMR-audio ?


It was the 1st of June 2017 when we got the call if we (Richard Hoogeveen and Johan R.) could come over to our friend Jan Mulder (also known as Dalojan in the audio community).

It became a very special day that changed our life.

That day, the three of us, were together for the first time in the many years we knew Jan. Jan decided that we should meet. Jan’s biggest fear was that all his audio ideas and designs would be lost. Jan was seriously ill and lay in a bed in his audio listening room. 

He talked for hours and made me promise to continue working on new ideas and use his designs and equipment and he said "if you can ever sell it, do it". Jan shouted why don’t you use HMR, the first letters of our surnames. This proposal was retained.

Jan Mulder died on Sunday morning the 4th of June 2017 while I was on my way to him. He was only 65.

We should have worked together much earlier when Jan was alive, but I did my best to put his and my ideas into some wonderful products and designs. As promised Jan and I still continue to work on new stuff !

Johan R. is more the person who advises in what it should look like. He invented the HMR logo. The first attempt was immediately good.

In memory of our friend Jan Mulder.
