-==== 1Bit-FullAdder ====
-The 1Bit-FullAdder sums 3 (//A//,//B//,//C//) inputs and outputs a //sum// bit and a //carry// bit.
-{{ :projekte:logicfulladder_rev1.png?500 |}}
-Therefore 8 relays are used. I know I can build it from 6. But for didactic reason I decided to use 8. For details see the schematic.

-==== 4Bit-Controlled-Inverter ====
-The 4Bit-Controlled-Inverter board is able to invert 4 bits. The board is enabled by the Enable-Inverter-Switch on the //ControlPanel//. It also indicates the input bits and the output bits by LEDs.

+The PCBs for the 4Bit Register and the Logo did arrive. I assembled them successfully. I'm now waiting for the new Relays HK19F for the final test of the registers. In the Logo-PCB there was a little mistake but I succeed fixing it by scraping away two traces.
