LittleBits 'Bread-bit' to Prototype Your Own Bit!

Introduction: LittleBits 'Bread-bit' to Prototype Your Own Bit!

In this instructable, we will make a custom bread bit to allow prototyping of your own LittleBits modules.

Warning! make sure you never feed more than 5volts DC into a LittleBit module or bad things might happen. This is true of both the signal (orange) and VCC (red) connections.

Step 1: Ingredients

You will need the following:

  • Wire cutters/strippers
  • Soldering Iron and solder
  • 1 x LittleBits Wire module
  • 1 x each of Red, Orange and White breadboard jumper wires
  • 1x piece of white card or plastic 50mm long and 35mm wide
  • scissors
  • double-sided adhesive tape
  • about 8cm of small-guage heat-shrink tubing

Step 2: Cut the Wires in Half

Take the LittleBits Wire and cut it in half (buying some of the following from Sparkfun would let you avoid cutting your precious Wire Bit )

Cut each of the jumper wires in half too.

Step 3: Strip the Wires

VERY CAREFULLY, strip the ends of all the wires.

Step 4: Add Heat-shrink Sleeve and Twist the Wires Together

Cut a short piece of heat-shrink and slip it onto each of the jumper wire sections then twist each jumper to its matching colour on the wire bit (half).

Step 5: Solder the Wires Together

Carefully solder each of the twisted pairs together then trim them with the wire cutters.

Step 6: Bend the Wires and Slip the Heat-shrink Over the Joint

Bend the soldered wires along the length of each jumper wire.

Slip the heat-shrink over the joint, making sure it is covered.

Step 7: Shrink the Heat-shrink

Using a hair-dryer (or a cigarette lighter), shrink the heatshrink until the joints are held tight.

Step 8: Cut Out the Base

Take some card or plastic and cut it to 50mm x 30mm.

Cut a notch about 6mm wide and 8mm deep to accommodate the connectors.

When I get a chance, I'll re-do this with a nice piece of acrylic or other plastic.

Step 9: Attach the Two Halves of the Wire Bit

Using double-sided tape, stick the bit connectors onto the card.

You might need to build it up a bit with tape so the connectors do not protrude too much.

Step 10: Tidy Up the Wires

Flip it over and cut grooves to feed the wires through to the top side side of the base.

Step 11: Attach the Breadboard

Stick the breadboard onto the base and you are ready to go!

  • white = ground
  • red = vcc (+ve power supply)
  • orange = signal

Once again, don't feed more than 5v into a LittleBit or it might be damaged.

There are many possible variations of course. It might be more flexible to leave the wire bit parts un-attached.
