A basic LCD clock in a Gameboy case

It's been a long time since I wanted to make a Gameboy shaped alarm clock,
So long, that Nintendo did release an official Gameboy clock, and so so long that it ran out of stock!
Ikea does a nice cheap clock, the Klockis, it is a clock with a inclinometer: depending on how you flip it it has a different functionality (clock, timer, alarm, thermometer). Its screen is a bit smaller than the Gameboy's but it looked like it could work.
I already had a few Klokis laying around, so I ordered a Gameboy aftermarket case and started the project.
I managed to assemble the console and the clock together. The result is ok, it could have been better but I followed the advice on "How to finish your weekend projects in a weekend", I decided to call it a day and switch to another project.
What was appealing about this project was I could use to commonly available items that roughly fit together. I think it would require much more work to have a more polished result, for example finding a slightly bigger LCD clock that fit better in the Gameboy would be nice but I think I would end up ordering a lot of useless LCD clocks before finding the right one. I also thought about using Xiaomi LCD thermometer since their firmware is updatable, but it seems smaller and it is not designed to display time.
I might do a second version in the future, with a flash cartridge on a real Gameboy. Powering a gameboy 24/24 just to act as a clock would be a bit overkill energy wise, but it is the perfect excuse to do some GB development ;-)

I hope this project will inspire you, don't hesitate if you have any questions!

  • 1 × DMG gameboy case
  • 1 × Ikea Klockis
  • 2 × tactile switch buttons
  • 1 × prototype board

    Step 1

    First, drill holes in the prototype PCB , cut the part so that it fits.
    Then, solder the buttons on the top and the cables on the back.
    Drill the PCB case so that there is room for the cables. Retrospectively it would probably have been better to solder the cables on the top, I wouldn't have had to slaughter the case so much, but it works
    I soldered buttons for the cross, even I didn't use them in the end.

    Step 2

    With a Dremel or a similar tool saw the sides of the clock.
    Drill holes in what remains of the frame of the clock so that you can screw it later to the front of the Gameboy case.

    Step 3

    Now we need to solder some cables on the clock.
    Unsolder the battery holders, and keep them for later, then solder some jumper cables to power the clock.
    Then solder cables on the button pads, I tried to remove the "vernish" on the PCB but it didn't work very well, for one of the button,I ended up following the lines and soldering on the other side of the clock.

Thanks Mike.

Yes, I just ordered a empty case, I suppose the Gameboy is still popular and a lot of people are refurbishing old consoles with new cases so it is easy to find them on ebay or Ali-express.

It's also why I didn't do this little hack earlier, I didn't know it could do it without scarifying a real gameboy.

Oh that's interesting, you didn't gut a Game Boy but just ordered an empty case? Was this one someone else removed the guts from or is it new for replacing damaged cases?

Clock is a nice look. I think the sideways orientation of the Game Boy actually makes it look a lot more interesting.
