About us

Numerous ideas from several people have contributed to the development of the HSRvote. You can find out how it all came about under History. Today, we are constantly developing the system further.

History

It started with an idea from two assistants who built a buzzer from an eval kit for entertainment at a family party. The participant had an electronic circuit with two batteries and three buttons in his hand. This basic functionality was later expanded to four response options, just as the HSRvote is built today. The only difference was that it had to be lighter, much lighter ...!

To avoid having to constantly change batteries, the aim was to reduce power consumption. Two initiative students on the electrical engineering programme then developed the MuChoi eco without a battery, which simply had to be shaken long enough.

The HSRvote also had to fit comfortably in the hand. This gave rise to the HSRvote classic generation. A materials engineering student designed a suitable housing and produced a prototype using a 3D printer. An injection moulding tool was then made to produce a small series of 2000 units on HSR's own injection moulding machine. HSRvote classic lasts for several years on one button cell and weighs a fraction of the original device.

The current generation, HSRvote battery free, is an innovative version that works entirely without a battery. Four commercially available piezo discs are used as buttons. The energy required for the transmission process can be obtained entirely from the mechanical work of pressing a button.
