Madox designed the BitBltBlade, a WiFi controlled POV lightsaber designed to display images in conjunction with long exposure photography. The BitBltBlade uses the hackable TP-Link TL-WR703N router and Kean’s USB Expander board to wirelessly control a strip of RGB LEDs.
The concept of operation is that the user would use their smartphone which can upload photos (aka almost everything except an iPhone) to connect to the router’s access point and access a web interface. Using the web interface, the user can then select to upload a small picture or photo to the router which is then rescaled and converted into a format to be ‘displayed’. The user can then set options such as timing between columns which affects how fast the display updates.
