    Hi all, I have developed the electronic boards of the wrist computer for a friend and I decided to build my own bracelet. This is my very first project where I don't make only the electronic boards so I hope to get good results.
    First of all I had to recreate my circuits in 3d and was not easy because I had to measure each component with a caliper to get the right dimensions.
    That was a really important step because it lets me to model the external parts with good precision.
    I don't have experience with clay or other techniques so I opted to build it in 3d. It may sounds insane but I'm going to buy a 3d printer this week and give it a try.
    Updates coming soon

    First pictures, the source image:


    and my version:


    I will make electronics at first, 3d parts are still not definitive.
    You can suggest improvements if something is wrong or could be better

    I was considering the prusa hephestos, but I have seen the manufacturer BQ is going to sell a new version, the hephestos 2.
    I will take a decision when its price will be known to the customers.

    Last week I had problems with my laminator so I had to rebuild its control circuit board.
    Finally I am ready to begin.
    The picture below shows the boards without components.
    Next step: soldering - as soon as components will be delivered

    The circuit boards look pretty cool by themselves. Can't wait to see the finished project :)

    Added solder mask to the boards, to avoid copper oxidation

    Thank you all, I hope to begin soldering today.
    Unfortunately I am still waiting for the delivery of some components and I cannot start

    This video shows how my circuits work, I hope you like it.
    As you can see there are two power connectors but I used only a battery pack.
    When I will assemble the boards with the plastic parts if sound will be too low I can use a separate higher voltage battery for the onboard audio amplifier to get a louder sound

    That is absolutely amazing! Great work!

    Thank you, I'm very happy to see you like my works.
    I have begun the printing of the first part to see if I have a good alignment with the boards.

    After four hour I got a low resolution model and it was fine so I printed the definitive part.
    It takes about eleven hours!
    If you don't believe me, watch the display at the beginning, it says speed 80%, 50% completed, 5:53 time elapsed.

    If I did not know that Yautja were fictitious, I would think that you had some Yautja tech the you reverse engineered. They are fictitious are they ?

    Remember my friend, people think they are fictitious but also my grandmother's teeth are fictitious too. If she can eat...
    A word is enough to the wise ;)

    Thats some amazing piece of electrical work. I envy people who can do this, it takes me three attempts to put my phone battery in the correct way !
