Large project box

6.0" long x 3.5" wide x 1.875"

PB-L project box 1    
Label  

lid label

1

Printed label for the lid including 2 laminating sheets for front and back

 
Drilling template   drilling template 1 A paper template is provided in order to obtain the correct placement of holes for the components.  

1/4" dia wooden dowels

or

plastic tubing

 

wooden dowels

or

 

poly tube

4 in

The 1/4" dowels or tubing may be used to help position the label on the lid for gluing.

(If your kit has tubing, you may need to cut it into 4 sections.)

 
9-V battery holder 9BH laydown battery holder 1 9-V battery clips in to this laydown container. The supplied hook and loop strips are used to stick the holder down to the inside of the project box. red wire is positive; black is negative
SW1-3 SPDT

SPDT switch (red)

3 SW1 provides power, SW2 selects between photogate and microphone input, and SW3 selects between two delay ranges. With the switch in the position shown in the photo, terminals 1 and 2 are connected. In the opposite position, terminals 2 and 3 are connected.
Pushbutton, momentary, normally open PBO pushbutton switch 1 Used a test button for the delay unit no polarity
Panel jack for AC/DC adapter PJ AC/DC jack 1 Receptacle for 9-V AC/DC adapter as an alternate power source When the AC/DC adapter is not plugged into the jack, terminals 1 and 2 are shorted internally. This connection opens when the adapter is plugged in. Because of this feature, terminals 2 and 3 are used to supply power from the adapter, while terminals 1 and 2 are used to supply power from the battery. Terminal 2 is shared by the two power sources and is connected to ground.
3.5mm mono panel jack 35MJ
3.5mm mono panel jack mono jack gray
cream gray
5 Three of these are used for outputs and two for inputs.

When a plug is not inserted into the jack, terminals 2 and 3 are shorted internally. This connection opens when a plug is inserted. (There are both cream colored and gray versions, but they have the same function.)

3.5mm stereo panel jack 35SJ 3.5mm stereo panel jack 3 One of these is used as a receptacle for the photogate cord and the other two are used for the camera output jacks. Terminals 1-3 connect to the sleeve, ring, and tip respectively of the corresponding stereo plug.
BNC jack BNC 3.5mm stereo panel jack 1 provides the pulse waveform output to a scope The tab on the side is grounded; the center pin is for the output signal.
