Manual:

This is a detailed manual for assembling the BattleBit. If there are any questions feel free to ask Ibo or Jelle!

Soldering Dip-14 sockets

The sockets will be used to mount the logic gates of the vehicle.

Place the sockets as follow on the PCB. Make sure the notch of the socket is facing forwards

Solder two diagonal pins of the sockets (E.G. pin 1 and 8)

Check if the socket is laying flat on the PCB, so not like this: Solder all other pins:

Soldering the pin headers

Place all 13 headers

Flip the PCB upside down

Solder one pin per header

Check if all headers are perpendicular to the pcb

Like: And not like:

Solder all other pins

Soldering On/Off switch

Place on/off switch: Solder the pins on the board.

Soldering the 8 warm white LEDs

LEDs have a polarity. Make sure that the anode (positive, longest pin) and the cathode (negative, shortest pin) are correct!

Bend the legs of the LEDs. Bend 4 LEDs with the cathode on the right, and bend 4 LEDs the other way around with the anode on the left

Place the LEDs on the PCB as shown on the picture. Make sure the polarity is correct!

Solder 1 pin

Check if the LEDs are laying flat on the PCB
Solder the rest of the pins
Trim the legs of the soldered LEDs

before the next step you have to put a shrinking tube around the IR tracking LED. Shrink the tube with some heat of your soldering irong Cut it to length of the IR LED

The last step is to solder the two IR tracking LEDs. Unfortunately there aren't any pictures of this step. On the outer perimeter of the PCB look for "IR Tracking led. Just above or below that text there are two holes and one small black resistor with the numbers 2200 (220 ohm). Place the IR Led with the cathote (shortest leg) towards the resistor. Make sure the LED is flat on the pcb and solder in place.

Soldering the Light Dependant Resistors (LDRs / Photoresistor)

Bend the legs of the LDRs. LDRs don't have a polarity so it doesn't matter which way you bend them. Place the LDRs in de following way

Solder 1 of the legs
Check if the LDR is laying flat on the pcb
Solder the other legs

Wheels

Put the 50mm o-ring around the printed wheel

Wheel Base

Carefully remove all the 3d-print support material with the help of some needlenose pliers.

Place the 9 hex nuts in the corresponding holes of the wheel base:

Place the motors and attach them with 30mm bolts. Make sure the motor leads are facing outwards

Push the wheels on to the motor shafts

Push the 9v battery cable through the small hole. Make sure the red and black wire are as shown on the picture Bend the battery cable as shown in picture below.
