Bộ chuyển đổi Binary–Decimal (10-bit) – Binary-Decimal Converter

This is a simple binary-decimal converter, with 10 bits.
Print the body and 10 copies of the plate, later using a metal or plastic rod to serve as a pivot/axis so the plates can cover the numbers (powers of 2: 1, 2, 4, 8, etc.) on the bottom half.

To convert from binary to decimal:

Build the binary number on the top part, lifting the plates when you need a 1 and lowering them when you need a 0. Always align the number to the right, following the logic of a calculator.
Sum all the powers of 2 the are uncovered by plates to get the decimal number.

Example: Convert 101110 to decimal.

1. Build the number, aligning to the right. The top part will read: 0000101110 (check images).
2. The covered powers of 2 will be: 512, 256, 128, 64, 16 and 1.
3. The uncovered powers: 32, 8, 4 and 2.
4. Adding up this numbers we have: 32+8+4+2 = 46

To convert from decimal to binary:

Factorate the decimal number in powers of 2, and uncover these numbers, which will lead to 1s on the top part. For each decimal number, there is only one combination of powers of 2 that sum up to it. Cover the powers you don't need, which will lead to 0s. Read the binary number above.

Example: Convert 733 to binary.

1. Factorate 733 to powers of 2, which will lead to the following sum: 512+128+64+16+8+4+1.
2. Note that the powers 256, 32 and 2 are not used, so they should remain covered.
3. The resulting binary number reads: 1011011101 (check images).
