A retro steam drive calculator that can be calculated anywhere with fire and water

In order to prevent the occurrence of the situation that the battery runs out and the calculator can not be used at the critical time, should we make a calculator that does not use batteries in the first place? And it was madeSteam driven electronic calculator. It is a dish that it can be calculated anywhere with water and fire even if the battery civilization collapses with the retro appearance and the magnitude of the force and the driving sound that can not be thought of as a modern one.

I want to calculate using a calculator ... When it is important to think that it is important that the calculator's battery runs out and it does not become usable.


"It is this kind of time!" Was placed on the table, a steam-powered electronic calculator that does not use batteries.


Because it is the size and weight you must lift with both hands, with a handle securely.


Power section.


An old-fashioned voltmeter that I can not imagine just being made.


Han numerals on the button.


The body of the main body is decorated with goldsmiths.


A portable, function-oriented calculator can not have a presence and impact.


When using it will give a fire with the Chuck man.

The engine began to move with an intensely making sound like blowrollroloro ......


The meter was referring to "no" ...


Bun is tremendously swayed by "possible".


Push "ON" button.


"0" is displayed on the screen, and it starts up properly.


Calculation could be done without problem. Calculation is possible with fire and water, and it is safe even if the battery civilization collapses.


Calculation is also easy.

Using the contents, remodeled to a retro voltage meter.


A hundred equal large calculator ... ...


Disassemble and remove the battery and solar cell.


For the decorative parts I used a gorgeous metal fitting for a Buddhist altar.


The way to make it is from the following. First of all, we create a framework.


Combine each part.


Like this.


Replace the battery checker with a voltmeter.


Old design which I can not imagine as a modern one.


Next take out the button from the calculator.


Painted in gold.


Print out new notation.


Then you can paste it on the button OK.


We will also paint the body.


Make a rusty red body.


It also colors the plate on which the power section is placed.
