Building the FLipmouse

Currently, we have no detailed information how to build your FLipmouse.

If you have your construction kit, following hints are important to successfully assemble the PCB and the case. Having problems with the construction set? Please open a GitHub issue.

PCB (mainboard)

• Use the BOM (bill of material) to reference the part names on the PCB to the real parts
• Due to the stacking of some parts, please solder C2 (capacitor), AUX (5x2 pin header) and I2C (2x1 pin header) at the beginning. Otherwise it is not possible to solder these parts (their pins will be hidden under the Teensy)
• The last part should be SG1 (piezo buzzer), the buzzer is located over a few parts
• Solder all parts with the minimum distance to the PCB!
• The long push button is S2
• The Teensy is soldered on the BOTTOM
• After soldering the Teensy, please clip the pins on the TOP to the shortest possible length.It will be easier to solder U$2 (pressure sensor)
• The colored LEDs (LED1, LED2, LED3) have to be bent in a right angle. These LEDs should fit into the bottom case part.
• The IR LED (LED5) can be bent to 90 degrees. This depends on the direction, which the LED should point to.

PB (daughterboard)

1. Attach all 4 screws to the acrylic part. The screw head should be on the engraved side (4 circles are engraved, as markers for the FSR sensors)
2. The daughterboard should be on the opposite side. Try to put the PCB on the 4 screws. The 8 landing pads should be visible.
3. If it is possible to press the PCB and the acrylic part together, it's time to glue: remove the PCB, apply the rapid glue (just a little bit, the 4 screws SHOULD NOT be glued) and press the PCB/acrylic part together
4. Wait.... Until the glue is hardened
5. Try one FSR sensor: There is the possibility to put the FSR sensors in the wrong direction. Ensure, that the upper side of the FSR is visible on the acrylic part (the upper side is NOT black). Feed the contacts to the other side, using the similar cuts in the PCB and the acrylic part. The pins HAVE to be soldered directly on the opposite side. If the landing pads match the 2 pins, the sensor is positioned correctly. If the pins and the landing pads are 90 degrees turned, then turn the FSR sensor 180degrees.
6. Apply the 2side adhesive tape on the engraved circles.
7. Put all 4 FSR sensors to the adhesive tape. Careful: the tape is very sticky, try to put the round sensor part in the middle of the engraved circuit.
8. Feed all 4 sensor terminals through the PCB/acrylic cuts to the PCB side.
9. Solder the 8 pins to the corresponding landing pads. ATTENTION: the terminal lugs of the FSR sensors are made of plastic. It is not wise to heat them with the solder iron... Use tweezers to move the pins to the corresponding landing pads.
10. Last step: Solder the female connector (5x1) to the PCB. It won't be possible to solder it as close as possible. This is caused by the acrylic on the other side. The connector must be soldered on the TOP side.

To ensure a high durability of the adhesive tape, mount as soon as possible the corresponding acrylic plate with the rubber pads (see following section).

Case

If it is available, the best solution is a glue dedicated for acrylic glass (e.g.: Evonik Acrifix). Please build the sensor carrier module in one step. There is enough time afterwards to make a break!
