DIY: triple fixing a proto board
three sets of patches. 2 resistor networks needed their values halved so I paralleled an identical (47 ohms) one across the existing one. that's one patch.
another patch is to have pullups for the TI branded port expander chips. that's the 2nd set of yellow r-networks (the ones to the far left in the photo).
the 3rd patch is where I had to use a too-small r-network on top (not seen, would be far right set of SIP pins) but I didn't bend the leads over to get the 'power dc' led wires. some small solder bridges across adjacent pins fixed that one.
the board is now ready for operation in the real word (lol).
