 The base station is designed to run 24/7 on 5V and to be connected to a PC, so you may prefer a stabilized 5V power supply, and not running on batteries. Any USB power supply will do well, and many mobile phone chargers are working at 5V. The base station is designed to run 24/7 on 5V and to be connected to a PC, so you may prefer a stabilized 5V power supply, and not running on batteries.

   * **USB-to-serial connector:** Either solder a 90 degree pin header here or some wires, which makes it easier to place the USB-to-serial PCB in a houseing. If using a pin header, make sure the shorter part is inserted into the SHC PCB.

-  * **ATMega:** Before inserting it, you may want to check the voltage levels when switching the power on. Pin7 should have VCC (3,3V) against pin8 (ground). If you have different voltages: don't panic, nothing is broken, nothing is fried. Search your error. To insert the ATMega, bend the pins at 90 degreed by placing the ATMega on the table and bending it carefully. Then insert it into the IC holder. Be sure that you are not charged with electricity (ESD!) when touching the IC pins. +  * **ATMega:** Before inserting it, you may want to check the voltage levels when switching the power on.

-  * **RFM12B:** You should also check the voltages first before soldering the module. At the place for the radio module the pad beside the antenna and at the opposite side the third pad should read about 3.3 V.

-describe it...+This is an example how to integrate the electronics into a nice housing. 
 +Here a black plastic housing was used ([[http://www.conrad.de/ce/de/product/520985|Conrad, 2.15EUR]]). 
 +The left figure shows the planned arrangement of parts: The smarthomatic base-station pcb, the FTDI FT232RL based serial USB adapter and the LEDs. 
 +The housing contains 4 pins inside for screw mounting, but it was on the wrong place, so it was removed with a drill and a chisel. On the side wall the marks for the USB-port and the LEDs are visible.  
 +The third figure shows the final assembly, the second LED was omitted. 
 +All parts were fixed with hot glue.
