This poor specimen is the mighty SSI2162 being strung up by its pins aloft two SSOP adapter breakouts, since the chip is too wide to fit across a single adapter.
As such, the inner pins on each adapter have to be wired to the outer pins, which I’ve done on the underside of the boards.
This would be the second homunculus of the sort I’ve created, after the first creature tore itself from its bindings when slight pressure was applied to the chip from above, as the frail SMT pads were the only things holding the two boards together.
In anticipation of this happening again, I created an adapter for the adapter using stripboard, which you can see beneath the accursed monstrosity.
The dumbassery may not be particularly my own fault due to the seeming unavailability of commercial adapters for this very specific chip package, yet it still stings all the same.
I finally caved and started my kosmo sized modular and case..
I decided multiplex or mdf wasnt good enough. So bought some actual, real wood! However after sawing my pieces I made the dumb mistake of not including the thickness of my planks.. so now my sidepanels are 3,6cm too short. So I’ll have to buy some more wood and redo it. Maybe I’ll remake them into a single row case or something..
I managed to solder a 24 pin 74LS154 chip socket upside down this week. Pin 1-24, 2-23 etc, couldn’t work out why my board wouldn’t work and realized pin 1 had the decoupling chip by it’s leg. I really couldn’t resolder everything to the right places, so my solution was to pop the chip out, bend all the legs through 180 Deg and insert the chip upside down. Worked a treat.
haha
I designed a PCB for a 4 voice MIDI2CV/GATE interface and forgot the CV output connectors…
