Large project box

6.0" long x 3.5" wide x 1.875"

PB-L project box 1    
Project box labels       Stick on labels are provided in strips to identify the components on the project box.  
Template for box lid       A paper template sized for the lid of the project box is provided in order to obtain the correct placement of holes for the components.  
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
Single-pole single-throw toggle switch SW1 SPST switch 1 On-off switch for power no polarity

Single-pole double-throw toggle switch

(may have blue or black base)

SW2 SPDT switch (blue)or SPDT switch (black) 2 Used to select between two circuit paths. This switch is distinguished from the SW1 above by the three terminals on the base. The two SPDT switches select between sound and photogate inputs for the delay unit and between short and long delay time ranges. The center terminal is common to the two circuit paths. no polarity

Used as variable resistors for control of sound (5k) and photogate (10k) sensitivity, for fine (100k) and coarse (1M) delay adjustment, and for variable timeout (100k)

no polarity; center terminal and on

Pointer knobs

 

PK knob 5 Used as pointers for potentiometer settings  
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 2 One of these is used as a receptacle for the microphone cord; the other is used as an input jack for triggers other than the on-board sound and photogate triggers. Examples include a contact trigger and a light-activated trigger.

When a plug is not inserted into the jack, terminals 2 and 3 are shorted internally. This connection opens when a plug is inserted. Terminals 2 and 3 are used to connect the sound trigger and photogate to the delay unit internally. Terminals 1 and 3 are used to connect an external trigger to the delay unit.

3.5mm stereo panel jack 35SJ 3.5mm stereo panel jack 1 This is used as a receptacle for the photogate cord. Terminals 1-3 connect to the sleeve, ring, and tip respectively of the corresponding stereo plug.

RCA panel jack

RCAJ RCA panel jack 4 These are used as output jacks to connect to a flash unit or camera. Terminal 1 is connected to ground. Terminal 2 is connected to the desired output (sound, photogate, instant or delayed timer output).
Red LED RLED red LED 3 Used for power on, photogate alignment indicator (LED1 on PCB), and triggering indicator (LED3 on PCB). The shorter leg is negative. This is also the leg nearest the flat on the lip of the case.
LED holder LED-M LED holder 3 Used to mount LEDs on the project box.

3.5mm mono connector (male)

35MP

3.5mm mono plug

2 This is the plug for the microphone cord and the external trigger input.

For the microphone, the sleeve is connected to ground and the tip to the microphone input.

For an external trigger, the sleeve is connected to ground and the tip to the positive output line of the trigger.

3.5mm stereo connector (male) 35SP 3.5mm stereo plug 2 This is the plug for the photogate cord. One is for the interrupter-style photogate and the other for the individual emitter and detector style. The tip is connected to +9 V, the ring to the photogate input, and the sleeve to a 470-ohm dropping resistor that then goes to ground on the breadboard.
