Yeah the one I tried was the newer guy with the brighter screen, to which I was unsuccessful. The cap on the audio line is generally a good thing, its a safety buffer, unlike some other models it doesn't filter anything audible- that I've found, then again I never messed around with that model- then again the old gameboy sound comparison site also doesn't show degradation- aka highpass filtering.

there is a cap on the audio ground that just protects against drop out on heavy bass, but for example in the DMG the two caps on the headphone jack board are there to turn the signal from digital to analog to drive headphones, where as for recording you want a line level supply which is what i was trying to get from the SP. the source i got was before the amplifier and volume control meaning the volume did nothing to the audio output. the point i found had higher gain, was DC (from what i can tell) and generally didn't have any amplifier hum in it.

oh you just added a output jack so you dont need the adapter. got it. edit: thats a odd place for a jack being that holding it would be awkward. I take it there was no room on the back side?

from what i could find that was the only place the jack could go without causing problems to the mounts, it could fit at the back but something would have to go. but the socket is ok if you just have it sitting and playing but maybe not so good if you want to hold it

hi all,

this is a DMG front board with the screen swapped out for a gameboy pocket screen, it has also been backlit with a white backlit and the poleriser has been reversed for high contrast biverting.

sound the alarm! you're going to have uncomfortably high contrast, you will have so much contrast your gameboy will be like, sllooooowww dowwwnnn and you will be like fuck you and smash it on the floor and ask me to make you a new one.



this is for sale at £70 (GBP) posted world wide,

for extra cash i will provide a biverted motherboard or anything really that you might want. let me know: ralph (dot) nex (at) gmail (dot) com

thanks!

(more gameboy stuff on the way, midiboys and arduinoboys let me know if you want dibs before hand)

Well, not BatchPCB for the motherboard, but something similar (probably 33each) unless I end up making a bunch of them at once. If I did a real order like that then I could choose the mask and silk colors. As far as inverting it goes, I'm not too sure about that. It would be a bit tricky and I'm not sure if the fab house would like that very much, but I'll look into it.

fair enough, white would be perfect if it could be done, especially for the new project, tho anything other than green would look awesome in a transparent case.

its still awesome! would it be easy to invert the screen print to make this PCB white?

the PCB fabhouse will do that.  you don't assign colors in CAD design.  you tell your fab house what you want...  say, green soldermask with white print, or white soldermask with black print

but i assume this will be going via BatchPCB which from what i understand only does green PCBs, so i am wondering if there is a way to cheat by having the whole pcb screen printed white to get a white PCB.

When I had originally started this project, I had only meant for these to be bought by those who had not the time, skill, or money to do it themselves.  I love making things myself and I bet 90% of the people on this board share the same passion for making things.  It was never my intention to make people feel that the only way to get an ArduinoBoy was through me.  I suppose I just did too good of a job.  I'm thinking that 68 ArduinoBoys brought into this world by my hand is more than enough, and I consider it highly unlikely that I will ever build one to sell again.  Experiment, maybe, but not sell on such a massive scale as before.  Of course, that leaves me with a little over 75 left over printed circuit boards I really don't need.  Good thing they make great coasters. big_smile

you have PCBs left??

well thats perfect! sell those to people who want to make their own, do like a simple guide and provide just the PCB, i bet that would sell well and get people into making stuff

Blue? I don't see any blue screen cover.

from the first picture.

the lighting is just bad in that pic though.  all the pics are of the same looking unit.

unless i'm missing something...

yea they are all the same unit, the top pic has a longer shutter time to get the backlight, the others are using a flash

hi all, i am just posting this gameboy here to try and save the ebay fees!

i have a yellow midi gameboy, comes with pre pot pro sound, and a yellow biverted back light, also comes with a brand new screen cover with the film still on it.

this is a very clean example of a DMG, which is getting harder to find now (i should know i check ebay every day!)

i am looking for £200 for this, postage is free to anywhere in the world.

reply here or email me if you are interested smile [email protected]

thanks everyone!
