Zsolt Várady
managing director
|
|
Zsolt Várady's professional career started in 1997 when he was elected to join the university group developing the official website of the Budapest University of Technology and Economics and he started working part-time for the University IT Service Centre. Later on, he worked as a Macintosh operator and web designer, both as a full-time employee and as a freelancer.
In April 2002, Zsolt launched the website WiW.hu, one of the first portals at the time of the revival of community networks.
In September 2002, he became the managing director of Wiwnet Kft, but gave up the development of the WiW site two years after its launch and joined T-Online Hungary. At T-Online, he worked on community services and – following iWiW's acquisition by the company in 2006 – the development of the revived iWiW site.
Zsolt moved to Berlin in October 2006 and established Plexipi Prototyping GmbH on 30 November 2007.
Awards
- 2005: "e-Hungary Award", awarded by the Hungarian State
- 2007: "János Kemény Award", John von Neumann Computer Society

18. May 2010 Visited SENSOR+TEST 2010 fair in Nürnberg. 31. March 2010 Webalert development. Finished working model of the whole system. 23. August 2009 We finished the development of a time-synchronized, six-axle CNC driver for the
"Polyfilm modulator" project of bauhaus lab. 15. May 2009 The second version of Webalert's working model is ready. 16. February 2009 Butterfly Effect Generator launched in Berlin. 21. November 2008 Website updated. 17. October 2008 We have finished programming and the model of the “Web alert” device is now fully operational. Currently the device reports the number of new incoming emails to the mailbox specified. 10. October 2008 We have succeeded in what we had not even expected: the motion detector worked fine on the first try. 2. October 2008 The LAN module is operational and we have established connection between the two radio modules. Field tests indicate that the radio modules can communicate with each other up to a distance of approx. 50 metres outdoors and 2 floors in a staircase. 17. September 2008 The printed circuits of the LAN and the radio modules have now been completed. Smallest line width: 6 mm, smallest VIA diameter: 0.2 mm. 30. May 2008 The first product concept is ready based on experience gathered from the operating models of the subfunctions.
The next step is to specify the details of how the product is supposed to operate. 28. April 2008 The first working modell was completed. It was given serial number 0001. We are currently working with version 0.3. 25. March 2008 The desktop CNC machine was also delivered. The machines for etching printed circuit boards are due to arrive in 2-3 weeks. The first working modell may be completed soon. 1. March 2008 The company moved to
its final location. 30. November 2007 Incorporation |
