+===== Lessons Learned =====
+  * Make the LED indicators from Cupper!!! Green soldermask is really transparent!
+  * Use blue or white soldermask with blue LEDs
+  * Make the signal connections on the front of the adder. This assists the understanding better.
+  * Use the mounting screws for power supply.
 ===== Status =====
+==== 09.Nov 2021 ====
+Finally added the transparent plexi backboard, the diodes and also oiled the wood. The project is finally finished.

+==== 23.Oct 2021 ====
+The sky blue version is ugly, so I bought a new one in transparent. This looks nice. Also I finally found time to put some oil on the wood. This also looks nice. The project is finished now and I am happy with it. Will upload images later.
+==== 03.Oct 2021 ====
+Finally I just ordered the plexi backboard in sky blue. I hope it looks nice.
 ==== 11.May 2020 ====
-Finished the 4 Bit Relay Adder. But will add the backboard later.

 I know I can build an AND gate from one relay. But in this preproject I build it from two. It is easy to explain how it works this way.

 == OR ==
 The OR gate is very simple. As High is 5V and Low is floating we can just connect the wires to get the or logic.
