Binary to Decimal Converter using relays.
000000000(0) to 111111111(511)

This circuit can convert an 9bit binary number to a decimal number.
Set the binary value with the switch at the bottom, and press the push-switch in the 7-segment of the second digit to start the conversion process.
In fact, this circuit can convert up to 10th, but it has been detuned due to lack of space.

This is incredible. How where you able to keep track of all the connections? Also, you managed to keep the running speeds up. Absolutely amazing.

By the way, does this use the Double-Dabble algorithm (aka shift add three algorithm)?

I see that this is called the Double-Dabble algorithm. I looked it up and found a similar process. The sequential circuit used in this circuit allows bit shift and BCD correction to be performed simultaneously. If you recognize each latch, counter, etc. in block units, the wiring method for each is the same, so it is not difficult to figure out the connection positions. However, only the 7-segment decoder is complicated, so I wired it while checking the circuit diagram. Tap the connection point and it will be indicated in yellow, so you can check it.

The reason I asked is because I also created some binary to decimal converters (4 bit https://everycircuit.com/circuit/6548980953251840 12 bit https://everycircuit.com/circuit/6083732712456192 ). Are you using a modified double-dabble approach?

Yes, I am using my own a modified double-dabble approach. Your circuits are also great👍

Thanks. I still can't get over how you managed to pack three 7-segment decoders in there, along with clock and state machine circuitry! Fantastic.
