[Doesn’t blow up! but still untested on an amiga or in a DB25 shell] If you order a set of these, please consider buying me a coffee and supporting open source creators Should fit inside a standard DB25 shell (compared to a 3D model. not actually tested for fit yet) deets: Github project

[UNTESTED] Should fit inside a standard DB25 shell/housing [NO IT WON’T use This one] deets: Github project

tested to work but there is an improved version here … Intermediate board to allow a drop-in replacement of an improved RGB video encoder chip CXA1165 in typical applications such as megadrive/genesis, Amiga A600/A1200 models. the 16K needs to be a 1% tolerance (or accurately tested) resistor and Y/C connections are broken out for S-Video mods to be attached (extra 75R + 220uF RC components needed in line with each)

If you order a set of these, please consider buying me a coffee Indicator LED board for testing activity on a gameboy (or GBA) cartridge socket. LED’s are 0603 size and resistor arrays are 4x 0603

If you order a set of these, please consider buying me a coffee This is a SMD component spin of Simon.Plata’s design on Atari age forums. the thread with all the design info is here http://atariage.com/forums/topic/271678-simple-diy-composite-video-mod/ this spin uses 2x SOT-23 for the transistors and replaces the board previously made at https://oshpark.com/shared_projects/BsstvIeq Q1 and Q2 can be MMBT3904/3906 as per Simon’s original design but I have BC850/859 on hand so I’ll be trying those out as they are nominally similar so the silkscreen just indicates where the NPN and PNP variants go but in theory any similar general purpose transistor pair should work. C1 is optional and does not appear on the original design but some people have found it beneficial to put a cap on. check the linked thread for details
