Assembly

Tool

• Screwdriver
• Tap cutter Mx
• Cutter knife

For mounting on street lamps or the tubes of street signs, we need an intermediate piece between the box and the post. Use the M3 tap to cut an internal thread in each of the four holes in the adapter plate from the laser cutter

Now take the 4 M3x14mm cylinder head screws, insert them through the recesses at the corners of the housing (from the inside to the outside) and screw them to the adapter plate.

• First insert the Velcro tape into the middle opening with the soft side facing upwards and guide it towards the cut-out
.
• Then place the base plate in the housing with the loose Velcro ends facing upwards and screw tight with M3x5mm screws. The orientation of the plate within the housing does not matter.

Attach battery to base plate with Velcro fastener.

Carefully insert the radar module into the 3D print holder so that the 4 pins protrude through the gap in the holder and the 6 pins on the opposite side protrude through the large opening. The module should be firmly inserted into the 3D printed part at the end.

• When attaching the Teensy&Audoshield to the pins of the radar module, you just have to make sure that the holes for the screws in the audio shield match those of the 3D print holder.
• Then you can connect the 6-pin connector first and then
• Plug in the 4-pin connector so that the cable is soldered to the second pin (as seen from the jack connection).
• Then attach the audio shield to the bracket with 3 M3x5mm screws.

• Now you can screw the feet from the laser cutter to the 3D print holder using one M3x5mm screw each. Do not screw them on too tightly so that you can still move the module.
• The longer of the two long edges points towards the wide end of the 3D print holder, while the overhang on the short edge points away from the radar module.

The feet are only in the base plate for the photo. You do not need the base plate here, it can remain screwed into the housing.

The slot for the MicroSD card is now located between the Teensy and the Audioshield. The micro SD card must be carefully pushed into the Audioshield slot with the contacts facing downwards as far as they will go.

Now insert the button cell into the button cell holder. The positive pole of the button cell must point towards the cover. Make sure that the switch on the housing of the button cell holder is set to "ON" and only switch it to "Off" if you have to change the button cell anyway.

Insert the radar unit next to the battery in the slots provided. The slot for the MicroSD card faces away from the battery. The radar unit is held in place by the screwed-on cover, so you can easily access the MicroSD card at any time.

Insert the rubber seal into the groove once all the way around and cut off the excess with a cutter knife.
