It is a project of a clock based on an old lamp wi-18. Housing was made of empty chocolate boxes.
Boards were made in thermal transfer method, protected by rosin dissolved in methylated spirit. The only problem that may occur during the construction are so called „ghosts” on the display, but you can find right load on the Internet so you can easily deal with that.
The clock was made in two versions: lying and hanging. The first one was painted from the inside with three layers of spray paint and covered with lacquer few times. The second version is without paint.
Glow, RTC and Atmega power are on xx7805, except that for the glow you have to give two diodes in the series (on the scheme it is only one diode, but when you use two of them, voltage drop is larger and there are no „ghosts” on the display).
