Small wireless keyboard and mouse combo.Hardware that I could have done without, but used anyway Plasterboard Masonry Wall Hook - 5 Pack.Ramset Super Wallmate Toggle Anchor (Hollow Wall Anchors).x2 Pine Dressed Standard Grade 42X19MM 1.2M.SanDisk 32GB Ultra microSDHC UHS-I Memory Card.Micro USB cable (to power the unit from the monitor).3pc Heatsink Kit for Raspberry Pi 4 (I only used the 1 Heatsink for the CPU).fbi software could be launched from Terminal, so there was no need for an OS GUI.PiicoDev sensors were used as they offered a near plug and play usability.The monitor needed to support DDC/CI for brightness control over HDMI, provide power to the Raspberry Pi via USB (less cables up the wall), and having an ultrathin bezel made building a frame a lot easier.Using the existing VESA mounting brackets on the monitor to attach to the wall meant I did not have to engineer a frame that would have to support the monitor's weight.Mounting a dismantled laptop into a picture frame was a nightmare, having to access ports was another disaster, etc Previous attempts to build a digital picture frame from a laptop failed miserably.I come from a Windows OS background so my Linux expertise is minimal There were a number of lessons learnt in getting to the final project build. Wallpapers thanks to: L'Outlander - City On A Hill, provided by Lofi Girl Why I built it this way I have also included a section at the end of unsuccessful software choices if you are considering other options in this space. I have written the instructions in a modular way so that you only need to complete the parts you require, for example, the light sensor, touch sensor and frame are optional. Lastly, I expanded the project with a touch sensor to safely shutdown the Raspberry Pi and provide additional functionality. It also incorporated a light sensor that adjusted the brightness of the monitor depending on the brightness of the room. The project was built on a Raspberry Pi 3 Model A+. I concentrated on setting up the computer/software side first before building a wooden frame and mounting the monitor to the wall. It needed to be easy to build and operate smoothly. The idea behind this project was to build a large digital picture frame at a lower cost than the ones you could purchase.
