Measure Wire Length

Make sure to leave extra slack for the connections that are on the outer side of the circle. 

Strip Wires

Prepare the wire for tinning by stripping a small amount at first. We'll tin the ends so the strands don't come apart.

Tin Wires

Use solder to tin the tips of the stripped wire. 

Extend wire strip

We'll need to fit two wires together into the LED through holes to chain them together. With the tips tinned, strip a bit more of the wire off, this way we'll have enough bare wire to twist together.

Twist Two Wires

Align up two wires and use one to twist along the other.

Flatten Twist

Use a pair of flat pliers to smush the wires together. Resolder the twisted wires to connect the two threads together.

Solder NeoPixels

With the wires twisted, solder the six NeoPixels into a chain.

Solder Gemma

Use a third hand tool to hold Gemma and the NeoPixel 24x ring. Positon both so that they have a short distance to each soldering point.

Solder NeoPixel 24x Ring

Tin the NeoPixel 24x ring and then solder connects to Gemma.

Check Circuit

Test power your circuit to make sure no cold solder points are present. 

Attach Plate Ring Clips

Align up uniRing1Clip.stl to the rectangular holes on uniPlate.stl. The clips should fit tightly in place.

Test Position Circuit

Test wiring layout with a small amount of mounting putty or tack to position the circuit on to the uniPlate.stl part.

Mount Gemma

Snap Gemma into the grooves. You can use tack putty to secure the circuit into place. Rotate the NeoPixel 24x ring and mount to uniPlate.stl part.

Attach NeoPixels

Mounting putty / tack works great here as well. Apply a small amount to secure each Pixel around uniPlate.stl.

Assemble Gear Ring

Use uniGearClip2.stl to attach uniGear.stl to uniRing.stl

NeoPixel 16x Ring

Slip the NeoPixel 16x ring through uniGear.stl part.

Mount NeoPixel 16x Ring

Snap the NeoPixel 16x Ring to the mount. Make sure to position the wires close to the rest of the circuit.

Attach Top and Bottom Circuit

Snap together uniRing.stl to uniRingClip.stl part. Alternatively, we can use three pieces of 30 gauge wire to secure both halves together.

Tighten Parts

Use a pair of pliers to assist you while you fasten the 30awg wire to the printed parts.

Final Unibeam

Now you have an Iron Man-inspired repulsion weapon! This build can be mounted to your chest, on a wall or even propped up on a stand for your desk.
