Convert one output into another for 7 seg. display

(1/5) > >>

Spemo:
Hello everyone,
I'm trying to solve a problem.
In the past, I've build a few relay clocks, which used hundreds of diodes to convert the signal from the relays to a usable output for a seven segment display.

The problem is, these diodes take up a lot of space, and to be honest, all the wires to make it happen drive me mad. Also there is a problem with the connections, sometimes they can't be seperated electrically properly and that causes all kinds of problems with the counting circuit.

To explain the problem:

I have 10 outputs of the counter circuit, 0 to 9.
This has to be converted into 7 outputs, where several have to be on at the same time, to display a number.

I've attached a picture with the solution I used for it.


Is there a way to simplify this, maybe to use a single IC or something?

Thank you for your help

Literally any microcontroller with 10 input pins and a few output pins.
An 8 channel led driver IC can be used if the led digits are too big and need more much power than what micro can provide.

Arduino is cheap, plenty of tutorials around. once everything works on dev board you buy and use to code on, you can buy just the chip separately and program it.
Same for Microchip PIC micros - programmer is now 10-15$, chips can be less than 1$, editor and tutorials are free.

Note that pwlps' suggestion takes a BCD input, you have a decimal from your counter by the sound of it, you might find a decimal to 7-segment driver, but might also be easier to just put a decimal-to-BCD encoder in front of it (74HC147 etc), or change your counter to a BCD output.

Plus he would need a Decimal to BCD Encoder
