Hi Eddy,

If you have created your own pen may I ask which IR LED you are using?  I would suggest switching to a TSAL6400 if you haven't already, but you can also rough up the LED with a bit of sandpaper.  This will create a bit of a diffuser on the LED giving a wider light dispersion.

Hi Joe,

In March we actually released our 1.1 version of the Groove, I'm pretty sure this is the one you had received.  The biggest improvement from 1.0 to 1.1 was the casing.  Our earliest version used a urethane pour process which is designed for prototype development.  After our first round of feedback we agreed with everyone that the case needed an improvement, our 1.1 represented our shift from this manual pour process into an injection mold process.  Our 1.1 model is much stronger than our original 1.0 design.

In August we completed our re-tooling for our version 1.5 model.  Our 1.5 model has the following updates from our 1.1 model:

1.) The tact switch is different.  We altered both the placement and the switch being used to require less force.  Our latest switch should perform between 40 and 60 gmf.  The result of this was that both the tip, and the button should feel easier to depress.

2.) Our red button was a bit tough to press in our 1.1 model so we widened the casing to allow a more free movement requiring less effort.  We feel this combination along with the adjustment of the tact switch allows for much better performance for younger children.

3.) Circuit boards are now machined and pre-assembled.  This is giving us more control and consistency as we produce more and more units.

4.) Our battery holder has been updated.  We found in some cases the battery would pop out of the older holders.  The new ones hold a bit tighter than I would like, but I wanted to make sure it didn't fall out.

As a side tip I recommend using a Lithium battery when working your Groove.  The voltage stays between 1.2 and 1.4 pretty much the entire life of the battery.

We have been thinking about adding a few colors on our next run.  Any suggestions?  We were thinking black, but we can add more if there is interest.

Thank you guys for your great feedback and support.  This is the kind of thing that keeps us improving our products :).


-- please be kind to the developers uwe and boon jin put a lot of hours in to help support us :)..

"The Groove" has completed the pre-production work and is now being assembled.  We have started shipping orders with our earliest pre-orders first.  We want to thank all of you that pre-ordered this product.  All of you have been so patient and we sincerely appreciate it.  As you might imagine it has taken many hours of research and a bit more capital than expected to get to the end product but we're very pleased with the result.

Here are some pictures of pens being assembled.  We're ramping up production to handle larger volume.  We expect to be at 100% production by next week and are currently back ordered.  Please allow 3 to 4 weeks to process your order.  To our current waiting customers we sincerely apologize for the delay but we know you'll be happy we spent a bit more time to ensure its usability.

Better button - softer to the touch

But the best part of "The Groove" is that you merely have to press it against a hard smooth surface for it to turn on.  Look mom no button!

How hard do you have to press on the LED?

Do you have a triple beam lying around?  We actually pressed down on a digital postal scale to see how much force was required.  100 gm of force was enough to turn on the LED.

Hi Arsenal,

I might be able to help you with this.  Would you mind dropping me an email?  We can talk through what you would like to see and we can work together to build a great unit!  It really depends on how large you want the array.  Drop me a note and we can get started with this project :).  Once we finish the prototype I can then build a better form factor.  Functionality first, looks second! :).

Accessories / "The Spot", by IRPensOnline
« on: December 05, 2008, 07:48:24 PM »
IRPensOnline is proud to present, "The Spot".  "The Spot" is a wiimote attachment designed to allow easy use of existing tripods and mini tripods that use a 1/4" screw.  Screw "The Spot" onto a standard or mini tripod (1/4"-20 thread) and clip in your wiimote.

Nintendo designed those side grooves for future attachments.  We figured why not take advantage of it. If you look closely at the image to the left you will see where the two push outs slide into the side channels of the wiimote.  This attachment "hugs" the groove to allow you to take advantage of the pivot and height capabilities of a standard tripod.

Price: 14.95 + s/h
5.00 off to existing IRPensOnline customers (or with the bundle pack)
This is a pre-order item we are just about to finish up our first production run

We will ship internationally, please send me an email at [email protected] for details regarding international orders.  If you are interested in becoming a distributor I am looking for an organization or individual in Middle East, Australia, and Europe that can help with distribution.

We've completed our modifications for The GrooveTM 1.5 and have made a few updates.

1.) We have adjusted the casing to allow more movement of the red button.  The result is a lighter red button that is easier to press.
2.) We've switched to a better battery holder that wraps around the battery slightly holding it in place should you accidentally drop The GrooveTM.
3.) We have redesigned the board utilizing a better switch, as a result our tip also requires less force to operate.

One thing I thought worth mentioning is that the tip of "The GrooveTM" was designed for use on hard smooth surfaces that can withstand an LED being pressed and dragged against it.  We really hadn't considered it for LCD display applications as it could potentially scratch the surface of the screen.  Ideally "The GrooveTM" should be used on a whiteboard, a wall (painted perhaps), or a table.  If you are using it with an LCD display we would recommend picking up a piece of thin acrylic (1/8") to place over the front of your monitor.  This will give you a better hard surface to write against and will protect your screen.

Thank all of you that support the wiimote project each day.  Through your advice, counsel, and feedback, we are able to continually improve our products.  Please keep the feedback flowing!  Our goal at IRPensOnline is to build the ultimate ir pen, we've taken another baby step, but we'll need your help to take us further.


Cost: 29.95 + S/H will ship internationally (send an email for details)

I was thinking about something I thought might be fun.  Can we do an IR Pen-off?  We select a panel of judges within the whiteboard forum.  These judges would receive pens from several of us sellers so that an independent matrix can be created.  This single thread table would allow new members to select the option that most closely meets their needs.  We can call it the 2008 IR Pen Challenge.  I would recommend a panel of 5 judges.  Judges would get a huge influx of pens so we would have to be a bit strict on what constitutes a seller.  Pens left over could be redistributed to the entire community based on a lotto.  Proceeds could also go to the hardworking folks that are working on the software parts of this initiative.  I donate what I can, but there are many hours that are going into the software part of this. 

Thank you guys for all that you do!

I'm sure there are plenty of other things to consider, but I thought I would provide a list I would want to see if I was ordering a pen.  I'm biased of course, but I'd like to help us establish a market place of sorts for our online pens.  I think we're all proud of what we've done and it would be great to see a bit of friendly competition.


IR Pens / offers a Whiteboard marker trade-up!
« on: September 16, 2008, 04:39:53 PM »
Hi everyone,

I wanted to thank all of you that have purchased pens from our site.  We now have pens in 10 states and 4 countries!

I ran out of whiteboard marker casings :).  I initially thought 100 casings would be plenty, but quickly realized how many people are interested in this project.  For a limited time I am offering a trade-in plan for educators.

If you send me 30 dead whiteboard markers I will send you 1 completed IR Pen with the following specifications:

1.) Vishay TSAL6400
2.) 5mm momentary switch
3.) AAA battery holder
4.) AAA battery

This deal is limited to 2 IR Pens per school (60 donated whiteboard casings), and will expire once I reach my goal of 300 casings.  Please send an email to [email protected] for more details.

Hi Matt,

Your pen has the following configuration:

  • 401-1766-2-ND (switch)
    A23 Energizer (12V) - (battery)
    Vishay 6400 - (IR LED)
    120 ohm 2 watt (Resistor)

I am going to send you an updated pen using an Energizer AAA Lithium battery.  I spoke to the folks at Energizer and they feel this battery has a better curve at 100 ma (1.6 - 1.3 V).


Say Hi! / Hello from Rochester, NY!

Hi Everyone,

My name is Tino Agnitti and I am currently a Solutions Consultant with netsmartz, llc.  I am based out of Rochester, NY and have a BS in Management Information Systems from  I work with the e-learning group developing custom online courses and customized LMS solutions.

For those of you that want to order an IR pen, I put up a site

It is a pleasure to meet you all.  I'd like to take a few minutes to explain where your dollars go if you were to buy a pen from me.

I have completed the pcb and the first 3 IR Pen prototypes using an oscillating circuit (555 timer) and 2 buttons.  My design allows for an adjustment between 69ms on, 69 ms off, to 0/0 if you want.  I have included a potentiometer (variable resistor with a screw to adjust the frequency).  This is still in a proof of concept phase, but I have been able to fit everything inside the pen including the battery (pcb = 1.3 x 5 cm).  The hardware is complete and available for sale if any of you guys want to do some experimenting with a pulsing ir pen.  My hope was that initially this can be used for a right click detection.  After thinking about it more, and reading a bit more on others looking to implement this type of thing, I realized this concept could be taken further.

I am currently working to create a USB IR Receiver to be used in conjuction with the wiimote.  The idea would be to use these frequencies to "ID" the pens so that different colors can be used by users at the same time.  Smartboards currently only allow a single user to interact with the board.  They actually determine which color you are using by deduction; If blue, red, yellow are on the tray, you must be using the green pen.  My hope is that the IR receiver will help the application understand which pen is which and allow a more engaging activity.

In addition to this concept I am working to develop a portable rear projection display.  I am very excited to see that Boon Jin has been able to include multiple wiimote tracking in his current application.  As we approach multiple participants on the board we may introduce "blocking" as one person may block the camera view (even with multiple cameras).  Ultimately any multi-person, multi-touch display needs to use a rear projection technology to avoid this challenge.  I am currently working with a few materials to create a collapsible/portable rear projection display.

The proceeds from an IR pen purchase go towards additional research in the hardware we can use to make the classroom experience even more engaging.

Thanks, and I look forward to collaborating with you all!
