I have been using Raspberry Pis for a long time now. Used many of the commercially available cases. RPis can be run headless (without a display) or an HDMI/SPI display can be used. There are many cases that are available for the 5" displays, etc. But it would definitely be nice to have small display with maybe an LED and touch support. Say like the commonly available 16x2 char displays and a WS2812B led and a button. This led me to search for a similar thing on the Internet and finally to a ThingSurf. Found this: Design on Printables webiste for a Raspberry PI 4 with display . The Design is by user guytas on printables and already had all the things I needed. This was locally printed on a Creality Ender. The 16x2 display fit nicely. But as there was a need for an RGB did some "jugaad" and fitted an RGB Led below the button hole and a couple of capacitive sense buttons below the casing. Wrote a small program to showcase all of the features. The program shows...
Building the PlotClock by Joo from ThingiVerse with English Character support Plotters are fun things. One can move in a 2D space and do very interesting things. Been fascinated by plotters from a long time. Notable mentions like the Drawbot, AxiDraw, EggBot, etc. Always wanted to build a small inexpensive one which did not require too many components or a lot of domain knowledge. One of my favourite past-times is to ThingSurf ie check which open source designs are available and try to make them, either on Thingiverse or Printables, etc. Its a lot of fun and because these provide designs for real-world things, one can study and learn from them and also extend them to do other things. There is also a requirement of a device that will be a low-power notice board, like a limited power device that will just consume power for a short time, do some useful work, maybe display a message and go back to sleep. Things written on a sheet of paper remain visible for a long time. So it wo...
