KC7783 PIR Detector Module (Assem and tested)
 
This is a fully assembled and tested miniature PIR module (KC7783 with KC778B IC) with only 3 connections: Power, Ground & Output. Rated for 4 - 12VDC input power. Uses RE200B PIR sensor. Output is an active high pulse of approx. 0.5 seconds and remains active as long as there is motion. Range up to 10 feet. PCB size: 35mm x 25mm(CPS76)

20 second voice recorder/playback module (A93010)
 
PLEASE NOTE: This module, part# A96010, is actually an A93010. It is virtually identical to the A96010 and it operates the same, but downloadable datasheets are available for each for comparison if necessary. The small size is because the IC is in Chip-on-board form. One button is pushed down to record the message through the on-board electret microphone; A LED turns on during this time. The other button just has to be momentarily pressed to replay the message. A second momentary press during playback will stop the playback. Sampling rate is 4K. All you have to add is the speaker (not included) and 5V DC power (not included). We also have an A96010-kit which in addition to the part# A96010 also includes a speaker and two cable connectors to connect the unit to a power supply (not included) and the speaker. The record/play time is determined by the 52K resistor. If you change it to 89K you will get 30 seconds but at a reduced sampling rate. Operating current 25mA. Standby current 10 uA. Size: 34 x 23 x 11 mm. The module comes supplied as you see it in the photo. 

OPTIONAL ITEMS (Not included):
2 x (BB089) connector cable to connect the voice recorder to a speaker and power source.
1 x (PB244) Speaker
1 x Battery holder that can hold either 4 x AAA or 4 x AA or 4 x C or 4 x D cells. See our battery holders.

Audio to light modulator kit
 
Description: A music-to-light modulator is a circuit which controls the intensity of one or more lights in response to an audio input. The kit is ideal to give the lights rhythm to any party or disco without much money. Very safe operation as it uses an opto-coupler as a coupling device between the audio and the mains controlling stages of the circuit. This is the assembled version of our CPS12.

Specifications:
Input trigger voltage: 2.3 - 2.5V (min)
Operating voltage: 110 or 250 VAC
Power handling: 220W @ 110V or 500W @ 250V
PCB size: 2.16" x 1.63" (To help in the decision to select an enclosure keep in mind that the heat sink used in the kit is about 1" tall.)

PLEASE NOTE: THIS KIT USES 120V MAINS ELECTRICITY AND SHOULD NOT BE ATTEMPTED BY ANYONE WITHOUT THE PROPER SKILL LEVEL. THIS SHOULD ALSO BE BUILT IN A SUITABLE PLASTIC ENCLOSURE.
