Assembly instructions for the IR-Blue Kit.
First please verify the quantities in your kit and make sure you have everything. If not then please email firstname.lastname@example.org and we will take care of it.
You will need a good quality soldering iron, solder, a pair of side cutters and a phillips screwdriver.
Place the three resistors like this. They can face either way.
Bend the leads slightly outward underneath the board so they stay in place when you flip the board to solder them.
Solder the leads of the resistors and then clip the extra lead with the side cutters.
Place the two 10uf Capacitors like this. They can face either way.
Solder and clip the leads.
Place, solder and clip the lead of the three 1uf Capacitors.
The 22pf Capacitors hole layout on the board was too large for the capacitors we sent so you will have to bend the leads to fit.
Place, solder and clip the two 22pf Capacitors.
Place, solder and clip the 16Mhz xtal.
Bend the middle lead of the Voltage Regulator back towards the rounded side like this.
Place, solder and clip the 2.6V Voltage Regulator.
Bend the Diode like this.
Place the Diode like this and make SURE the stripe is facing the same direction as below.
Place the Switch like this.
If you have trouble holding the switch in place while you solder it you can hold it in place with your soldering iron like this then make sure it is still in the right position before soldering the other leads.
Warning! This is a very important and expensive part of the kit. Do not heat the leads for longer than a few seconds or you may damage the sensor.
Also be careful not to use too much solder on the sensor leads since they are thin and more than a little solder can wick to the other side of the board and create a solder bridge on the sensor. You can place a thin strip of Kapton tape or other heat resistant thin material on the bottom of the sensor to insulate it from excess solder wicking to the sensor.
Note: The more recent kits have a little strip of Kapton tape included in the kit. It is the yellowish piece on the back of the restickable pads. Place it on the front of the PCB over the sensor holes then poke the sensor leads through the tape to leave the tape as a solder barrier.
Place the MLX90620 Sensor in the board with the bottom tab facing the edge like the silkscreen shows.
When you solder the first lead of the sensor in place, make sure it is still flush with the board on the other side and not tilted. Solder the rest of the leads and then clip them.
Bend the black wire like this.
Place the bent end through the hole in the single negative battery contact then bend into a U shape like this.
Continue bending the lead down like this.
Solder the wire to the battery contact.
Make sure the solder has flowed onto the battery contact like this.
Do the same for the red wire and the single Positive Battery Contact.
Place the wires in the board like this.
Solder the wires and clip them.
If the other battery contacts do not stay in the case when you place them then give it a slight bend like this.
Place the battery contacts like this.
Push them all the way down into the slots at the bottom.
Place the battery contacts on the wires in the case like this.
Push them about half way down the slots like this.
Make sure the wires aren't pinched in the screw standoffs when you slide the board into the case.
Screw in one screw most of the way then screw in another to make sure the board is lined up right. Do not over tighten the screws.
There are 7 screws and we only use 3 for the PCB like this. The screws are all the same size.
Place 4 AAA batteries like this.
Place the back on and screw it on with the 4 screws. Do not over tighten.
The kit comes with 4 removable, washable sticky pads to help attach the IR-Blue to your phone, phone case or tablet. If they start to get dirty wash them with water only and when dry they should stick well again. DO NOT RELY ON THE STICKY PADS TO HOLD ONTO YOUR DEVICE. They are there to help it keep the same position as you hold it. You may want to get a case for your phone that you can attach the IR-Blue securely to then just slide your phone into and out of that.
Place with the phone offset from the camera and use the alignment function in the app to adjust for the offset.
There was a problem with the initial run of cases in that the ON and OFF indicators did not show up. Sorry about that, when the switch is closer to the sensor it is off.
