01 Walworth Road in London Deploys ePaper Smart Signs to Display Booking Information for Loading Bays
Walworth Road is a commercial street in London, consisting of independent cafes, restaurants, bars, small shops, supermarkets, major retailers, nail salons, and local businesses. As part of the Walworth Road curbside management project, businesses and retailers will be able to book the use of loading bays on this busy commercial street in South London. Double-sided ePaper-based smart signs will display booking information for each loading bay.
The project, initiated jointly by Grid Smarter Cities and Southwark Council, will commence in late February 2024, aiming to improve access for delivery drivers on Walworth Road to existing allocated loading bays and prevent unauthorized loading activities in these spaces. Additionally, the project aims to reduce congestion during peak hours on the commercial street and alleviate parking pressures when delivering to local businesses and restaurants.
02 DIY Keepsake Box with Raspberry Pi Zero W and ePaper Display
Software engineer Mike Buss customized a keepsake box for his three-year-old son using a Raspberry Pi Zero W and an ePaper that can be used as a digital photo frame. Apart from storing keepsakes, the keepsake box made by Mike Buss can unlock images of special significance through fingerprint recognition and display them on the ePaper display embedded in the box lid.
Mike Buss used a custom iPhone application to upload images to the Raspberry Pi Zero W and optimized the image display using the Floyd-Steinberg algorithm, employing dithering to achieve subtle shades of black, white, and red.
