Ugh! LEDs, Caps and Resistors... OH MY!

A project log for DDL4-CPU

A Modular 4-Bit CPU Design

Well, after a seriously hard week of debugging some new hardware at $DAYJOB, I was able to crack open a beer, and start assembling the Mega-One-8-One for the DDL4-CPU! I've populated all the capacitors, the current limiting resistors for the LEDs, and the LEDS. To make everything fit, I used 0603 resistors, caps and LEDs for the Mega-One-8-One. The caps and resistors aren't too much of an issue as they are not polarity/orientation sensitive, but the LEDs need to place with the correct Anode/Cathode alignment. I usually can do 0603 LEDs without an issue, as the bottom of the LED has some markers to indicate orientation for the Cathode. After placement, I use my multimeter on the diode setting to step through all the LEDs to make sure they are all placed with the correct orientation.... ugh this board has a LOT of components!
