    I haven't recently found any self-construction plans for a chess timepiece.
    The rules are simple
    1) Possibility to set at the beginning of the game the reflection time variable from 5 minutes to an hour
    2) Visual and progressive signaling of the last 5 minutes
    3) dual display indicating both elapsed times
    4) possibility to increase the maximum total time of an entity to be established with each move
    5) convenient button that interrupts the flow of time of a player and starts that of the opponent
    6) flash mode in which you give a maximum game time to climb.

    It could be a new project to be done together.

    It would be relatively simple
    A MAX7219 to manage the dual display for hours and minutes for a total 4 figures.
    There is still the possibility of piloting two other displays for the service indications or the seconds and others 8 + 8 led to make the visual indication of the last 5 minutes.
    Virtually everything revolves around that’ then integrated or an encoder or some button is used for the settings and the electronic part is practically finished

    I decided to carry out this project during my free time.
    The components are all in some drawer that are just waiting to be used.
    The main problem is knowing how this special timer should work.
    I thought it was enough to set a maximum playing time equal for both players.
    Two stroke, one for each player, they decrease during their turn.
    But after doing the program I realized that it's not what Amilcare wrote.
    By not playing chess I would like to know how it should be and what it should display.
    For the prototype I used an LCD display, but I have the version with 8 display a 7 segments and the max7219. I just have to mount the displays on the breadboard.
    Health Marcello

    Here the official chess regulation article 6 pag 10 and following while on page 19 the timing for the various game modes is explained in detail

    I read the pdf and found that what I did is a watch that can simulate the mechanical ones of 50 Years ago.
    Today, something else is needed.
    There are many types of counts and some I have not completely understood.
    I have doubts about the Fischer method which adds a bonus to every move. Let's assume the bonus is 20 seconds, if they are not used the new bonus is added to the new time obtained with the bonus ?. I try to explain myself with an example. The time at the end of the move is 30 seconds and then becomes 30+20 = 50 seconds. The next move is done solo 10 seconds. the new time is 40+20 = 60 or 30+20 so again 50?.(question 1)
    Another thing is the extra time that is sometimes decided.
    I have seen races that have a time 90 minutes – 40 moves + 30 minutes extra . If they are not exceeded 40 moves the game ends later 90 minutes?(question 2).
    I hope someone can help me get rid of these doubts.
    Health for all .

    For the second question, you only get the bonus if you exceed a certain number of moves
    For the first question, the times obtained by the bonus add up for the single move. If you don't use it, you lose them, it is an aid in case the game gets complicated and you have to think about the move following your action.
    Usually it is never used, the big ones expect at least a dozen consecutive moves of the’ opponent.
    Every move you make has already been planned and there is no need to think about the single move.
    If you happen to know someone who does chess competitions you will find that he has an extreme ability to predict what others will do with extreme speed.
    In practice they are trained in reasoning a 360 degrees with respect to whatever happens to him, analyze pros and cons of all possible consequences of every possible move e, it does it very quickly.
