Timer relay module circuit

I'm using this timer module :

[login to view URL]

But the product has problems and error, it can start without trigger, the decimal can jump unpredictable, etc.

So I decided to make my own timer relay module circuit.

It should have:

- Input Voltage DC 12V

- Use the same relay as the above product

- Memory Safe (the more the better)

- Time Delay Setting : 0 to 999.9 seconds

- Prefer 3 setting button. Start - Up - Down (other button configuration is ok too).

- 2 mode :

- Mode 1: Press Switch -> Relay ON (as set as the set value)

Note: Value that is safe is the time for the relay to be ON)

- Mode 2: Press Switch -> Relay ON - OFF - ON ~ repeat

Note: Three setting values: Relay ON time, Relay OFF time and how many times it should repeat.

WHAT TO CONSIDER:

- The circuit should be reliable, durable and heavy-duty use.

- Use only easy to find parts.

- The price of the above module is just $2 - $3. So, the circuit should be economical (doesn't meant that it should be $2-3 too). A little more expensive is ok, but not too much.
