Parts Guide for the Multi-Trigger Enclosure (MTE)

 

Below is a list of the parts provided in the Multi-Trigger Enclosure Kit. Click on the photos for larger images.

 

Name HiViz.com product code Photo Quantity Function Polarity and Connections

Large project box

6.0" long x 3.5" wide x 1.875"

PB-L 1    
Switches SW2 SPDT switch (red) 4 Used for on-off switch for power, input selection, delay range selection, and timeout selection. no polarity
Linear-taper potentiometers

LP1k

LP10k

LP100k

LP1M

4 Used as variable resistors for control of sound (1k) and photogate (10k) sensitivity and for fine (100k) and coarse (1M) delay adjustment no polarity; center terminal and on

Pointer knobs

 

PK 4 Used as pointers for potentiometer settings  
9-V battery holder 9BH 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
Pushbutton, momentary, normally open PBO 1 Used a test button for the delay unit no polarity
Panel jack for AC/DC adapter PJ 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 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 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.

3.5mm mono connector (male)

35MP

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 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.

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).

RCA connector, male

RCA-m

2 These are used as connectors on the cable from a flash unit or camera to plug into any of the four RCA panel jacks. The sleeve is connected to ground and the tip to the desired output.
Red LED RLED 3 Used for power on, photogate alignment indicator, and triggering indicators. While you can use the LEDs supplied with the MT-BB, extra ones are provided in case you've trimmed the legs of those LEDs too short for use on the project box. The shorter leg is negative. This is also the leg nearest the flat on the lip of the case.
LED holder LED-M 3 Used to mount LEDs on the project box.  
100-ohm resistor 100R color code brown-black-brown 1 This is provided as an extra resistor in case the one supplied with the Multi-Trigger needs to be replaced. no polarity
1-kilohm resistor 1kR color code brown-black-red 1 This is used as a dropping resistor for the power LED. no polarity
100-kilohm resistor 100kR color code brown-black-yellow 1 This is provided as an extra resistor in case the one supplied with the Multi-Trigger needs to be replaced. no polarity
0.047-μf capacitor 047C 1 This is used to divide time intervals by 10 for the delay range selector. no polarity
0.47-μf capacitor 0.47C 1 This is an extra capacitor that you may need if you trimmed the legs of the 0.47-μf capacitor that came with the MT-BB. The shorter leg is the negative side. This is also the side with the light blue stripe.
2-conductor cable 2CA-3 3' This is used in preparing the microphone cable.  
Heat-shrink tubing   heat-shrink tubing   Includes 2" of 3/32" dia tubing and 3" of 3/36" dia tubing for use in construction of microphone cable  
Hook up wire HW12 24" strands in 6 colors Ample wire is provided for all connections.  
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.
