This time I used selfadhesive paper to create the reinforcing stripes for the side walls. Less work, less mess and no sanding& cleaning after airbrushing required.
I decided to install the windows AFTER completing and painting the base module. For installation from outside I attached a piece of Tamiya tape as “holder”.
After removing the center part from the working base. Ready for airbrushing with dark grey. Center part ready for airbrushing off white. Result: after glueing both airbrushed parts together absolutely clean margin between dark grey and off white.
A few days ago I thought that I would have to abandon the project because I produced a great mess while covering the core with 4 thin cardboard sheets.
1st step of the rescue - operation: I airbrushed more than 10 cubic centimeter 1000 Mr Color leveler.
The CR 2032 is not able to supply the sheduled current of 10 mA. So I had to modified the circuit. Two large capacitors will be now the source for the two short pulses.
At the same time the most complicated and important tasks in this project. At the first attempt I tried to build the lantern house of 16 sole trapezoid shaped clear sheets: I gave up🙁. At the second attempt I constructed the lantern house of one bended piece of clear material. That worked🙂.
