elfy
elfy is an ambulatory wheelchair user who got (un)reasonably angry about a 599€ remote control and discovered that spite is an excellent motivator for reverse engineering: because understanding the device you depend on isn't just interesting, it should always be possible. Firmly believes that if your medical device has Google Play Billing integrated, something has gone horribly wrong.
Has now spent more time reverse engineering their wheelchair drive model than the manufacturer probably spent implementing the DRM.

A 595€ wheelchair remote that sends a handful of Bluetooth commands. A 99.99€ app feature that does exactly what the 595€ hardware does. A speed upgrade from 6 to 8.5 km/h locked behind a 99.99€ paywall - because apparently catching the bus is a premium feature.
Welcome to the wonderful world of DRM in assistive devices, where already expensive basic mobility costs extra and comes with in-app purchases! And because hackers gonna hack, this just could not be left alone.
