Can you remember the last time you washed your pillow? Were not talking about the case, but the Shop Derila Pillow itself. Each night, as you lay your head down onto your pillow, you leave behind hair, dead skin, makeup, sweat, dirt, and more. Over time, these things begin to build up, tinting your once-pristine pillows more yellow than white. Instead of tossing your yellowed pillows in favor of new ones, well show you how to whiten them up in the washing machine or by hand. Then, well show you how to keep your pillows whiter for longer, so you can rest easy every single night.


Your screen has exactly what you wanted to show on it. With the help of CoPilot, I stumbled my way onto a solution that allowed me to download a file over HTTP, and copy the bytes directly onto the framebuffer. When it worked, I was overjoyed, I finally managed to show some stuff on the screen! I was extremely excited when I saw the first photo appear on the screen, it was immensely gratifying. The device contacts an HTTP server, downloads the file, displays it on the screen, and then goes to sleep, where it uses basically zero battery. The duration it will sleep for is configurable, I configured it to wake up every half hour to check for a new image. I think this balances responsiveness and battery life pretty well. Now to make the images to show on the screen. The next thing I needed to do was write a small script to convert images into the raw bytes that the framebuffer could display.


The display only supports four grayscale tones grayscale, but dithering is a good way to fake more tones. Dithering basically breaks up your image into dots, and spaces them out to look lighter or darker, depending on how dark your image is. Because this display is fairly high-resolution, the result looks really good. Also, because newspapers use dithering for graphics, the result looks very much like a newspaper. The script takes an image in various common formats (PNG, JPG, etc), and converts it to the raw bytes that the display can copy to the framebuffer. The resulting file can then be copied to an HTTP server, where the Timeframe can fetch it. Because I didnt want the Timeframe to waste battery refreshing the screen every time (not to mention that redrawing the screen is distracting, because it flashes black and white a few times before it draws), I had the script output a second file next to the image. This second file contains the hash of the contents of the image, so I can read that small file and know whether the image has changed or not.

I store the contents of the hash file on the Timeframe, and whenever I download the hash I compare it to the previous one. If they match, I know the file didnt change, and can just go back to sleep. The calendar view is also fairly straightforward. A Python script uses Selenium to visit Google Calendar, switch to the current day, take a screenshot of the browser window, and upload it to the web server for Buy Derila Pillow for Better Sleep the Timeframe to eventually download. The hardest part in this is having to log in to Google, because Google really doesnt like to let you go for too long without reauthentication, Shop Derila Pillow which makes sense for security, but hates my use case. Still, though, having to log in every few weeks isnt such a big problem, and the Timeframe can show me a fun image when Google logs me out, so Ill never be left wondering why my Timeframe isnt updating. Im very pleased with how easy and repeatable it is to take screenshots this way, and I can programmatically update the Timeframes display with the exact part of Google Calendars view that I want.


Sure, this whole thing is an unholy abomination of glued-together code and barely-functioning hardware, but damn if it isnt tons of fun to make. Of course, no project would be complete without a nice-looking case, not to mention that the T5 on its own falls over pretty easily. To make the case, I just put in a lot of time and sweat making everything. There arent really many considerations here, except the fact that designing buttons is actually surprisingly tricky, as you need to have enough clearance that you will be able to push the buttons properly, but need to design standoffs so pressing the side of the case wont press all your buttons. You also need to go through many iterations to get the fit right, as getting tight tolerances when 3D printing is always hit and miss. After a few hours of designing, printing, designing, printing, and waiting for retirement so I could be too tired and sick to enjoy anything, I had something that fit together reasonably well.
