This project develops a precise method to measure battery pack longevity when powering electroluminescent (EL) panels of varying sizes. A photodiode connected to an analog input monitors panel brightness, while a custom-built timer tracks the duration of illumination. The system features buttons for pausing, starting, and resetting the clock, which measures hours, minutes, and seconds of battery life. This setup enables accurate assessment of how different EL panel surface areas affect battery performance, providing crucial data for optimizing power management in EL applications. The research was specifically conducted to gather data for the Crowd Supply Tinko project. The EL panels used are VynEL, which are iron-on and water-resistant. The combination of VynEL panels and Tinko technology facilitates easy and seamless integration into wearable designs. https://www.crowdsupply.com/daedal-technologies-llc/tinko-hush (btw, I need subscribers!)

I wanted to repurpose my Arlo Doorbell camera for use in my apartment. While searching for mounting solutions, I noticed other apartments using clamp-like adapters for Ring and similar cameras. However, my search for Arlo-specific clamps came up empty.
Undeterred, I purchased a compatible clamp and designed a custom adapter plate. This solution allowed us to mount the camera without drilling into the metal door or damaging the hardboard siding. The new setup has significantly improved our sense of security and enables us to monitor our package deliveries effectively. I designed the adapter plate using Fusion360 and incorporated M3x4x5 knurled nut threaded inserts for a secure fit. www.thingiverse.com/thing:6781776 Giotto, a talented Florentine artist, was considered the first genius of the Italian Renaissance. In the early 14th century, Pope Benedict XI sent a courtier to assess Giotto's skills for a potential Vatican commission. When asked for a sample, Giotto simply drew a perfect freehand circle in red paint, saying, "Here's your drawing." The courtier, feeling mocked, demanded another, but Giotto insisted it was "enough, and more than enough." Despite his doubts, the courtier presented the circle to the Pope along with other artists' elaborate designs. Upon learning how Giotto had drawn the circle unaided, the Pope and his advisers recognized Giotto's superior talent, setting him apart from other painters of the era.
