Lithophane childrens Alarm clock

thingiverse

My daughter had a alarm clock switching between two pictures. The electronics and interface were crapy (had to adjust the clock every week or so), so I decided to build my own. I decided to go with two curved lithophanes which I can replace when she is bored of the unicorns. The rest of the case I designed around the lithophanes. You can use the case either as designed or upside down. I ended up flipping it because that turned out better in the room and the screws were no longer visable (that is with the screen on the left top). You can also mirror the designs to fit your needs.With an ESP8266, a 1,3 inch OLED display, some transistors and some bright leds, this was pretty easy to setup. https://www.amazon.nl/AZDelivery-SSD1306-compatibel-Raspberry-Inclusief/dp/B01L9GC470/ref=sr_1_2_sspa?__mk_nl_NL=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=28091A4X45M5P&keywords=azdelivery+1.4+inch+oled+ssh1106&qid=1705146822&sprefix=azdelivery+1+3+inch+oled+ssh1106%2Caps%2C192&sr=8-2-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1&smid=A1X7QLRQH87QA3 The lithophanes are created at https://3dp.rocks/lithophane/ The settings are shown in the pictures. When creating the lithophanes, make sure that the uploaded images are the sames size on both width and height, otherwise they will not fit in the alarm clock.My original design did not fit the display properly, I changed the design to fix that. I did not print the updated design yet. The print fits on a Ender 3, for that you have to print it diagonal.
