Let's follow the instructions which is given below: Step-1: Take A Map Of Bangladesh with only division border ( Size: 6" x 8" ) and place it on the hard board of table calendar ( Size 6" x 9" ) with some glue and tapes. Step-2: The 1" of extension part of table calendar will be used for 8 switches of this. And the 8 switches will indicated 8 divisions ( Dhaka, Chittagong, Rajshahi, Khulna, Sylhet, Barisal, Rangpur & Mymensingh ) of Bangladesh. Make 8 holes in it and set 8 switches on it. N.B: But unfortunately, the 1" extension part is broken by me. That's why I am using a piece of plastic powder bottle for setting those switches. Sorry for that. Step-3: Take 8 (eight) 5mm LED's and 1KOhm resistors. The long leg of LED is positive (+) and it goes to 1KOhm Resistor. And resistors another portion goes to Red wires (+) which is positive (+). Finally, the another leg of LED's connect with Black Wires (-) which is negative (-). Step-4: Make 8 small holes on hard board of table calendar according to Bangladesh's Division Map. And place there 8 Red LED's into it with glue gun. Step-5: After setting all switches ( S1, S2, S3, S4, S5, S6, S7 & S8 ) on plastic portion then take 8 Pieces of small paper with the 8 names of Division Of Bangladesh and glue it in the bottom portion of those switches accordingly. N.B: Switches are setting on the plactic powder bottle portion instead of 1" extension part of calendar hard board. Step-6: LED's all Red wire (+) like L1, L2, L3, L4, L5, L6, L7 & L8 goes to all switches middle pin according the position of Division like Dhaka, Chittagong, Rajshahi, Khulna, Sylhet, Barisal, Rangpur & Mymensingh in the map location. Step-7: Connect all switches front/ first pin with same Red wire (+) and it goes to the mobile battery holder's Red wire (+). Step-8: Connect all black wires (-) of all LED's ( L1, L2, L3. L4, L5, L6, L7 & L8 ) together and it will be connected with mobile battery holder's black wires (-). Step-9: Now, set the hard board on the Styrofoam Case and tapes it together. Step-10: Now put some glue on Styrofoam Case at side and place here the charging port of mobile battery holder's and again glue it strictly. And you can charge it by any Charger with DC Male Connector. Suggestion: Now Play with others to guess them the position of Division Of Bangladesh. And make fun and learn with others by it. Enjoy...
