Smoothing boards Smile Smile The Tower of Power Mr. Purple Does this one have any dual use issues? OLS - UART sniffing OLS - UART sniffing Preparations for brain surgery Preparations for brain surgery Purple mockup of the new board The new board Find the error AAAARRRGGGHHHH !!! 14 days again ;-( Mostly assembled EPIC FAILRE An adapter saves the day Full blast Finally: PURPLE ! Is this the purple of purple? Leds are almost off And there was light. Old vs. New Not faked at all Depth of Field Depth of Field Old vs. New Openbench logic sniffer - pull-up/down wing - Rev… Done - two more to go :-( Openbench logic sniffer - pull-up/down wing - Rev… Old vs. New Openbench logic sniffer - pull-up/down wing - Rev… MBI5168 breakout board OLS pull-up/down wing OLS pull-up/down wing OLS pull-up/down wing MBI5168 breakout board Openbench logic sniffer - pull-down wing - Rev 0.1 MBI5168 breakout board Openbench logic sniffer - pull-down wing - Rev 0.1 More light for my 'workbench' Upcycling old prototypes ! Replacing a popped 7805 More light for my 'workbench' OLS pull-up/down wing Finished MBI5168 breakout board OLS pull-up/down wing It started to snow today... It started to snow today...
