This circuit periodically powers up a Camcorder, instructs it to record either 1 or 10 seconds of video, then powers it down again. Programmable for delays of 10 minutes to 24 hours. Requires a camera with a Control L (LANC) port and a power control pin. Handy for those Science Fair projects, or for security serveillance.

Ever want to use a stereo VCR to record only audio, but found that it needed some video before it would record anything? This handy circuit provides a blank raster that is perfect for these applications. Can also produce a test pattern of four gray-scale bars. Output is fully interlaced, standard 60Hz field/30Hz frame rate.

Trigger your still (film or digital) camera from various sources including lightning (using an AM radio), a light beam, an alarm circuit or a momentary switch. A single pushbutton is used for power on/off as well as mode switching, keeping the interface simple.

Control L or LANC is a standard interface for controlling audio and video devices. It is similar in some ways to RS232, but not enough to allow direct connection to your computer. By using the ELM624, the peculiarities of the interface are translated for you, allowing direct control and monitoring of your favourite A/V machines.
Be sure to visit Eric Cairon's web site for some great construction plans and software for use with this chip. This link goes directly to the English version of the site.

One of the messiest parts of getting started with stepper motors is creating the up/ down counters to drive the motor phases. This chip does all of that work for you, so that all you have to supply is a direction and a step input. The ELM310 provides dual modes of operation, easily switching between half-stepping and full-stepping modes, while also providing very high speed bidirectional operation.
(PDIP $7.00 CDN, SOIC $8.00 CDN)

This IC is similar to the ELM310, but only supports the single phase full-stepping mode of operation. This is useful if you only plan to use one mode.
(PDIP $7.00 CDN, SOIC $8.00 CDN)

This IC is like to the ELM310 as well, but only supports the half-stepping mode of operation. Again, this is useful if you only plan to use the one mode.
(PDIP $7.00 CDN, SOIC $8.00 CDN)

This chip is almost the same as the ELM311, operating only in the full-step mode, but it always energizes two phases at a time in order to produce more motor torque.

   The following devices are for use with vehicles that have an OBD or On Board Diagnostics port. This port is required on any 1996 or newer North American vehicle, and is used to obtain 'trouble code' information, as well as other things. For a copy of the related standards, be sure to visit the SAE web site. There are several other web sites, but the OBDII.com site (sponsored by B&B Electronics) has proven to be quite informative.

This device allows you to talk to your OBD (On Board Diagnostics) equipped vehicle using a standard RS232 serial connection. It transparently converts between a 41.6KHz J1850 PWM data stream (typically used in Ford Motor Company vehicles) and standard ASCII characters. The user need only issue the desired commands - the data formatting, error checking, bus arbitration etc. is all handled by the ELM320. Allows experimenters to inexpensively create their own 'scan tool'.

Similar to the ELM320, the ELM322 allows you to talk to your OBD equipped vehicle using a standard RS232 serial connection. It transparently converts between a 10.4KHz J1850 VPW data stream (typically used in General Motors Corporation vehicles) and standard ASCII characters. The user need only issue the desired commands - the data formatting, error checking, bus arbitration etc. is all handled by the ELM322. Allows experimenters to inexpensively create their own 'scan tool'.

Basically a resistance comparator, this device monitors the resistance of a standard (inexpensive) NTC thermistor, compares it to a reference, and provides a control output depending on the relative values. Proportional hysteresis is provided to reduce hunting.

This IC is used to relay the position of a garage door to a remotely located red/green LED. A simple two wire connection is all that is needed. With the addition of a couple transistors, these same two wires can also be used to control an output for operating an electric garage door opener. This one is handy for late at night when you're not sure if you closed the door or not.

An easy way to interface to light dependent resistors, or photocells. One external resistor sets the threshold point, and internal circuitry provides line frequency filtering, hysteresis, and delay on pickup and dropout of 1 msec to 10 minutes.

Use an inexpensive television remote control to control up to three separate devices. Handy if you just want to start up your shop vacuum, or turn off the lamp next to the television. This IC can't drive power line level outputs directly, but with suitable relays or triacs it will provide all the control you are likely to need.
(PDIP $7.50 CDN, SOIC $8.50 CDN)

Very similar to the ELM331, this IC switches to standby mode between temperature measurements, to reduce power consumption. This is convenient for designs that may be required to operate on a backup battery supply for extended periods of time.
(PDIP $7.00 CDN, SOIC $8.00 CDN)

Small control applications often only require a few port pins for outputs and feedback. This 8 pin circuit is perfect for these projects. It is controlled using a PC's serial port with standard 'AT' type commands, allows reconfiguration 'on the fly', and requires only a few external components for support.
(PDIP $8.50 CDN, SOIC $9.50 CDN)

All the basics for a home security system, in one 8 pin package. This integrated circuit provides delayed and immediate operation as well as automatic alarm reset after five minutes. Both pulsing and steady outputs are provided for driving a variety of alarm devices. Buy many and create a multizone system!

A single pushbutton press initiates either an eight or a fourteen hour timing cycle for charging Nickel Cadmium batteries. If desired, the period can also be programmed in one hour increments. Requires a full-wave rectified 60Hz signal for timing.

Reduce circuit board clutter when trying to obtain those very long time delays. The ELM381 provides 1 hour to 1 week periods using a 60Hz clock input. Digitally select one of four desired periods, apply a line frequency signal to the Schmitt clock input, and use the high current outputs to drive your circuit.
(PDIP $7.00 CDN, SOIC $8.00 CDN)

Reduce circuit board clutter when trying to obtain those very long time delays. The ELM382 provides 1 hour to 1 week periods using a 50Hz clock input. Digitally select one of four desired periods, apply a line frequency signal to the Schmitt clock input, and use the high current outputs to drive your circuit.
(PDIP $7.00 CDN, SOIC $8.00 CDN)

This integrated circuit uses no external timing components to generate signals with periods from 0.1 seconds to 10 minutes. Timing is digitally selected via four input pins, and complementary output signals are provided. It doesn't have as much output drive as a 555, but sure is much easier to use.
