So my GBBoy colour arrived and i gotta say the build quality on the thing is pretty okay. It plays all my old gameboy games fine and screen is nice and bright, the resolution is a bit ehhhh but for the most part its a pretty good buy of $50 I took it apart and probed around a bit with a...

Well my pcb is done although i anticipate probably forgetting one or two things, i always do, off to jlcpcb and hopefully my other parts from china get here soon too.

Dude... I solder for a living, and have been doing so for like 10 years, i could not do that, that is art. I have never seen such well done rework.

Monitor is a 29inch ultrawidescreen which is so helpful for circuit design when you can have data sheet up...

Right you are Aurelio i just had another look at the LM239 datasheet and it seems it sinks the output to ground anyway, YAY less components. The real challenge looks like it is going to be making the part for the flex cable connector in eagle. Not my strong point.

update update update did a bit of research on how the switch joystick works and how i might make that into a digital on or off for the gameboy buttons the handy dandy COMPARATOR CIRCUIT don't mind the terrible schematic lm239 is just a quad op amp hooked up to the cheapest switching npn...

Hi Everybody I had been perusing the forum for a while and noticed a build comp. Having just finished off a fairly big electronics project i thought what the hey, I should give it ago. My idea isn't the biggest or most grandiose but i believe it will be fun, challenging and completable...
