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 product code	Photo	Quantity	Function	Polarity and Connections
Large project box 6.0" long x 3.5" wide x 1.875"	PB-L		1
Single-pole single-throw toggle switch (base may be black or blue)	SW1	or	1	On-off switch for power	no polarity
Single-pole double-throw toggle switch (base may be black or blue)	SW2	or	3	Used to select between two circuit paths. For the MTE, the three SPDT switches select between sound and photogate inputs for the delay unit, between short and long timeouts, and between short and long delay time ranges. The center terminal is common to the two circuit paths.	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	or	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) (jacket may be gray or black)	35MP	or	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 (may have metallic, white, or red ring)	RCAJ	or or	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 (ring may be red or black)	RCA-m	or	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				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.
