Assemble

Prep Resistor

Use flat pliers to bend the resistor legs to fit them into the perma-proto breadboard through holes.

 

LED layout


Refer to the circuit diagram to arrange the LEDs and resistors in place. 

Tac parts in place

We'll need to filp the perma-proto board upside down to solder the LEDs and resistors. Use small pieces of tack to hold the parts in place while soldering.

 

Solder LEDs

Carfully double check that each part is flush against the perma-proto and begin soldering each leg.

 

Cut LED legs

Grip the legs with flat pliers and then cut each off with flush cutters.

Tin, strip and solder wires

 

Measure and cut the wires for power and ground, then strip and tin the them to easily solder to the through holes on the perma-proto. 

Cut Trace 

To prevent ground from bypassing the resistor, we'll need to cut a trace on the row to separate the ground from the LED from the ground to the wire.

 

Solder external power and ground wires

Lay the PowerBoost and Perma-Proto board on the bottom part of the brush box and measure the wire length needed for the power and ground rails on the Perma-Proto. 

 

Connect rails


Run power and ground to both sides of the Perma-Proto board by soldering each rail together.

 

 

Check connects

Inspect each through hole from any bridging. You can use a solder sucker if any connections are bridged.

 

Solder PowerBoost

Tin the 5V and G pads on the PowerBoost and connect the + and - wires on the Perma-Proto.

 

Solder Fan

Connect the + and - pads on the PowerBoost to the red and black wires on the fan.

 

 

Tap standoffs

Create threads for the standoffs by creafully fastening the screws before mounting the boards. Make sure to drive the screws in as straight as possible while fastening. 

 

Mount boards 

Use M3 x .5 x 6m screws to mount the Perma-Proto board to the bottom standoffs.

 

 

Mount fan


Use #6-32 x 3/4 inch or M3 x .5 x 20MM screws with nuts to attach the fan to the grill section of the box.

Add screws from the outside of the box and add the nuts to the inside of the box to mount the fan.

 

Battery

To make the cleaner portable, we can add a 2500mAh lipo battery to the inside wall of the box with double stick foam tape. 

Attach bottom

Align the mid part of the box so the port opening and USB port on the PowerBoost match.  Snap the mid part of the box into the lid part on the bottom section of the box. You can slide the mid section in at an angle if the tolerences are tight. 

 

Plug in USB 

Connect the micro USB cable through the port opening and connect it to the PowerBoost.

Attach the USB on/off switch to the other end of the micro USB cable and test to power by plugging it into the wall or battery power bank.

 

Attach Top

Snap the top part of the box the rest of the box, slide it in at angle if the tolerences are too tight.

Success! You're ready to dry your brushes!
