Use an IR Blaster to trigger Picture and Picture

Jim in NJ sent us this IR blaster idea: Jim has several IP cameras throughout his house and a linux DVR machine near his TV. The linux machine is configured to montior the IP cameras using linux motion software. When motion is detected he configured the PC to output the desired camera full screen and send an IR command to the TV to display the PC video input in PiP. This same idea can be extended to other applications like baby monitors using sound detection as the input instead of motion. The system could also be implemented with insteon instead of a dedicated PC. Thanks Jim!

Scientific Atlanata Exploer 940 (SA E940) IR Extender

Brent in Mississauga, Canada e-mailed me about obtaining an IR extender for his SA Explorer 940 set top box. The E940 uses the same pinouts as the standard Motorola Style IR Extender, but it uses a 56KHz IR Receiver instead of a standard 38KHz. We swapped out the IR head for Brent and shipped him a sample. Today, Brent reported he is successfully controlling his Scientific Atlanta STB behind closed doors with the help of our extender!
We're glad to here we were able to get Brent a solution for only $13 plus shipping and would be happy to share the solution with others as well. Just e-mail us if have an E940 box in need of an IR extender and we can swap out the head of our standard product for you as well.

Albert's FTDI IR Receiver/Transmitter

We found Albert Huitsing's page on how to make a homebrew IR receiver and transmitter using an FTDI MM232R prototype module and thought we had to give it a try ourselves.  We were thinking this little module would be the perfect thing to interface our motorola style IR receivers and Tivo Style IR Transmitters to the USB port.  To do this, all we would need to do is modify Albert's design to include the necessary 1/8" (3.5mm) jacks.

We decided to run this test by making a small board.  This way, we figured we could make up a couple for only a bit more money and share the results with others. The board is pictures above with our 1/8" plug IR receiver cables  plugged into it and it works great (notice the improved styling on the IR Receiver head as well).

Albert also has a patch on his website to allow for transmitting, but we haven't tried that yet.  We did put an option to install another 1/8" jack on the back side for connection to our tivo style ir blaster.  We'll post here when we get around to testing transmitters.

 We did notice a couple items when testing the receiver so far that should be noted:
(1) In the lirc daemons/hw_ftdi.c we had to change the sample rate from 16 to 32.  It seems our FTDI chips sample at double the rate as the ones Albert tested.  We didn't see a spec in the datasheet showing the correct sample rate.  We also had to compensate for the doubling of sample rate by halving the baud rate from 4800 to 2400.

(2) On computers with only a USB 1.1 port, mode2 worked, but irw did not.  On all computers we tested with USB 2.0 ports both mode2 and irw worked as expected.

Upgraded Motorola Style IR Receiver

If you bought a Motorola Style IR Receiver from us in the past month you may have noticed an improvement to our design.  We modified the housing and strain relief to make the product look even better.  Here's one of the new designed receivers stuck to a plasma tv.  Of course the old style still works great too.  Some people even prefer the old style with the slightly smaller head.

For the foreseable future we'll be shipping this new style casing unless you note in your order you would like the older style.  We hope you continue to enjoy using the "IR REMOTE INPUT" jacks on your motorola boxes!

Build your own cheap multi function camera controller

I just found this instructable article by Josh on how to build your own cheap multi functional camera controller.  The basic idea is to use an SLR camera with an infrared (IR) controlled shutter along with a microcontroller.  Josh wrote some software for the microcontroller to choose shutter trigger options via a simple push button menu and then fire off the camera at the appropriate time. 

The infrared output is via an IR led.  Personally, I would have used one of our tivo style ir blasters with 1/8" plug.

This also got me thinking of a great use for our RS232 IR Blaster and RS232 IR receiver.  Using lirc or winlirc and a PC the same exact controller can be built to control your camera.  Yes, you'll need to have the PC near the camera, but this may not be a problem for some of the shots Josh had intended to take with this rig.  I also thing a PC based design can be made much faster and cheaper assuming the PC is already available.

Remember: If you make a unique setup like this using our parts and send us the details you can qualify for our food for your thoughts promotion.

Extra IR Stuff - Leap Frog LF-IRX-RX

We somehow end up with many extra IR components sitting around our shop. These are one off items that are taking up space and we have to get rid of them. We could put them up on e-bay, but the e-bay and paypal fees are so much it's not even worth it. I decided I'll start posting the stuff here to to avoid those fees (essentially saving the buyer money) and keep this stuff out of our local landfill.

Today I have an extra Leap Frog add-on receiver for the LF-IRX system Model LF-IRX-RX. I don't think they make this thing anymore, but if you have the original system you can expand it with this extra receiver.

In the box:
(1) IR Receiver
(1) AC adapter
(1) IR Blaster (I don't even know why this is in there, but hey it would cost you an extra $6 to get one of these on the main page of this site)

$15 shipped with payment via google checkout. E-mail to make a deal.

Keypad Linc as Access Control Keypad

I would like to use an 8 button insteon keypad linc as the keypad for an access control system.

The Idea
You enter a 4 letter code on the keypad and the correct code sends an unlock signal to a door strike

The Implementation Plan
First, the supplies I'll need:

This is the easiest way I can think of to accomplish this. I'm open for suggestions on how to improve the system before I test it out.

First, I'll set each button to send a different X10 Unit OFF Code. There are several reasons I am choosing X10 for this. I won't have to link the keypad with the PLC modem, I can use an ocelot controller if so desired, the keypad linc won't be waiting for an ack, and the keypad linc LEDs will remain off during the button pushes.

On the controller end, I can simply look for the correct sequence of X10 codes. If I get an incorrect sequence or a timeout I'll go back to the start of my script. If the correct sequence is entered I can send the code to the I/O linc device controlling the door contact. The keypad itself can be linked to the I/O contact controller such that the on/off led on the keypad indicates the status of the lock.

This system can be improved such that each user has their own code and entry is logged.

Access time restrictions can also be easily added.

With 7 buttons and 4 letter codes we have a 1:2401 chance of someone guessing the code. A timeout between incorrect codes can be added to the script to decrease the chances of guessing.

Automatic Christmas Train

Eric Sorensen has some info on controlling an IR based train set. To do the job, he made his own IR Blaster and receiver and used his sound card to capture the waveform.

This sounds like a great project to re-create with the IR Blasters and receivers sold here! It would certainly take a lot less time to setup with lirc.

Individually control up to 2,048 Infrared Targets

We have had several customers ask us how to control a large number of identical infrared targets. The most common application seems to be set top box developers who want to test hundreds of boxes all closely stacked in the same room. We have also seen demand for this type of system in hotel/bar applications with a large number of TV decoder boxes feeding a single media server.

The solution we typically recommend for these applications is the ocelot controller coupled with 16 zone IR expansion modules. Once connected, each ir blaster can be individually controlled by sending a command using the CPUXA protocol via rs232 from a PC.

More details on these items can be found on our special order page. Please contact mike at irblaster dot info with your specific needs and we can put together a great package deal for you.

foobar2000 on a laptop

Jeremy in NY wrote me to say he was using the cabled RS232 ir receiver on his windows XP desktop to control foobar2000. Foobar has a winlirc client plugin that makes this possible and he was enjoying the setup, but wanted to also have it work on laptop. As is the case with most laptopsl these days, his did not have a serial port. The solution: a 16C550 compatable PCMCIA uart card from dealextreme for just $17.25 with free shipping. Jeremy is now able to enjoy foobar on both of his machines!

Using WinLIRC with SnapStream Beyond TV

I found this interesting thread over on the SnapStream forums on using winlirc ir blasters with Snap Stream Beyond TV. Remember, I recommend the windows version of the ir blaster if you want the best compatibility with winlirc. Here is a direct shopping cart button for the windows version of the $12 RS232 IR blaster.

Add to Cart

To summarize the procedure, Snap Steam Beyond TV can call an external channel change script by adding the a key to the registry. For example, this registry code causes SnapStream to call c:\winlirc\channel.cmd with an argument of the channel number on every channel change.

[HKEY_LOCAL_MACHINE\SOFTWARE\snapstream media\EXETunerPlugin]

This same post on the SnapStream forum also has some info on using winlirc and IREX for an ir receiver. The IR Receivers from work well on both windows and linux so you can use them with this method.

Why Insteon over X10?

X10, Insteon, UPP, and ZigBee can all perform similar lighting control tasks. prefers insteon for several reasons outlined in the insteon product comparison application note. In summary, here is what the note has to say:

INSTEON: Moderately priced, highly reliable Dual-mesh RF & Powerline technology
UPB: Expensive single-band technology
X10: Inexpensive but lacks the robustness, flexibility and reliability required by home-control applications
ZigBee & Z-Wave: Single-band (RF-only) wireless networks that require a network controller

Here's a youtube video of some MythTV/Lighting control integration:

Insteon IR Receiver

The new Insteon IR Receiver will be available starting mid February to link your insteon devices to a universal ir remote control. You could also use it to link your pc to your insteon devices using one of our ir blasters instead of using an insteon usb or serial bridge.

The MSRP of this device is $100. As always, I can give much better insteon pricing on bundles so feel free to e-mail me a list of insteon equipment to get a price quote.

Also of note, if you don't mind running your insteon devices in X10 compatibility mode the X10 IR-543 is available today for $30 and is in stock and ready to ship. I have used the IR-543 on several projects to allow control of insteon lighting from the logictech harmony series of remote controls. Just e-mail me to order an IR-543. US shipping is still just $3.95/order.

HD Mediabox IR Receiver

I was contacted a few weeks ago by Jeff in California about my Hauppage PVR-250 replacement IR Receiver cable. Apparently, some folks on the pixel magic forums for the HD Media box MB100 and MB200 figured out that the IR Receiver input on the back of their HD Media boxes was the same as that of the Hauppauge PVR-250 cable. Only problem is the PVR-250 cable is a 3/32" plug and the HD media cable is a 1/8" plug. Adapters to convert are generally available at Radio Shack for this type of thing, but I had my wire shop build up something for Jeff pretty quickly to try out the theory and save some adapters. Jeff informed me the solution worked great so I'll be offering these cables for sale to the general public for the same price as the PVR-250 version ($10 + shipping). I'll add a cart button soon. In the mean time, you can just e-mail me at mike at irblaster dot info to order.

IR Blaster, IR Receiver, and Lighting control in one device

Application note: Using the applied digital ocelot as an ir blaster, receiver, and lighting control instrument all in one simple unit.

The ocelot can be programmed to convert serial port commands to IR commands and X10 lighting control commands. Furthermore, the ocelot can be programmed to transfer received ir commands to serial commands.

Also, since the ocelot uses standard RS232 signalling it can be connected to the PC using a usb to serial adapter.

I will be adding sample code to help setup this system shortly.

The ocelot is available on the Special Order page for $199 and typically ships in less than 1 week. Custom programming is also available.

LIRC on a Router

Yesterday I purchased a Buffalo WHR-G54S for a new little project. I wanted to run LIRC on it and add an IR Blaster and receiver. I started with the blaster part and it was suprisingly easy to get it up and running thanks to the help of some posts on the openwrt forums.
Here is a rundown of the basic procedure and I'll fill in some more details in the near future.
Step 1: Get openwrt to run on the router. The openwrt wiki has the information you need on how to do this. The steps I followed where under the "TFTP Method." Specifically, I used the tftp command on my windows laptop as it happened to be nearby the router.
Step 2: Open up the router and install an IR Blaster. You can see mine temporarily soldered onto the debug led in the picture. More details on this will be coming soon as this was the most tricky part of this operation. Of course, once I perfect all of this I will be happy to sell already modified routers.
Step 3: Install LIRC on the router. Some other openwrt users have posted lost of information in the forum on how to do this and have even packaged up the files you need. I used the package by esteevens. It only configures a transmitter, but it was a good start. Installing it on the router is easy. Just telnet into the router and enter:

# ipkg install

libgcc also needs to be updated:

# ipkg update
# ipkg install libgcc

Copy your LIRC config file to /etc/lircd.conf and then Start LIRC:

insmod lirc_dev.o
insmod lirc_serial.o
lircd --device=/dev/lirc/0

Now you are ready to start transmitting. Next I need to work on getting a receiver to work and rsh so that the router can communicate ir commands with another machine on your netowrk.
