Rave Radio


Rave Radio was 20 jaar geleden een radioshow met daarin tijdloze house van toen. Rave Radio is nu een radioshow in dezelfde stijl, gepresenteerd door Elger Jonker en Ruud van der Klugt. Rave Radio staat bekend om goede housemuziek met een twist naar de nieuwste stijlen en stromingen binnen het genre.

Ruud en Elger hebben honderden tapes ontvangen en gedigitaliseerd met een high end Nakamichi LX-3 speler en zetten dit online om zou de parels van de rave muziek te behouden: onvindbare, supervette, underground tracks die het daglicht niet konden verdragen.

A tribute website to the highest quality underground warez series: even with hundreds of thousands of copies sold in 8 years, it still was bound to be forgotten, untill the original domain name “twilight-cd.com” was freed from a domain squatter.

The site contains overview of all released issues, high resolution artwork, research and disections of the Twilight software. Many people contributed by donating their Twilight cd’s, dvd’s, links, media and stories. For example: Did you know the Belgium anti-fraud team got their own box filled with Twilights every month?

With: Elger Jonker, Tjeerd, Dirk-Jan and many contributions by readers and mainstream media.




Flippo’s are the Dutch version of Pogs / Tazo’s. It was the most succesful marketing campaign targeted at kids ever in the Netherlands. With popularity only between 1995 and 1997 the collection and all of it’s information and stories has faded out of collective memory.

Flippos.info has the goal to provide anything and everything about the Flippo. The site is based on my research, including conversations with various stakeholders and the biggest [insane] collectors.

With: Elger Jonker and information from many sources

Greenpoint – CT2 mobile communication technology


Greenpoint was a mobile communication technology prior to GSM. It was aimed at consumers and business to have cordless phones on the go: a revolutionary concept at the time. You could only receive a message someone wanted to reach you, you had to call them back near a basestation; a “greenpoint”.

Sjors and I started this site because we received a stash of Greenpoint phones at Hack42. We tried to get them to work and found there was no documentation left on the internet, so we fixed that. Currently Hack42 has the only working greenpoint consumer base-station in the Netherlands: of course we want to have a real base-station but it’s hard to find.
