On her blog, Lepht Anonym describes herself as "a faceless, genderless British biohacker. It lacks both gods and money and likes people, science, and practical transhumanism." Anonym practices, sometimes referred to as grinding - a subculture of biohacking - DIY surgery to insert electronic hardware under the skin.
The "Grindfest", according to cyborg Rich Lee, “is the kind of event where you can really put things in perspective.” As per Anonym, the event involves watching interesting films, putting together biohacking experiments, and discussing their results.
It comprised a facility for USB storage and a WiFi antenna - users could connect to it via their phone or PC, wherein they could download and upload files. "...It was immediately clear this might make an interesting subdermal device," Anonym wrote on her blog.
Over the next few days, the experimental device was readied to be inserted under human skin - extraneous components were taken out, the battery was replaced with a wireless charging coil, the USB storage was soldered down, and the box was coated with many layers of resin-type stuff to bio proof the device.
