Having explored the many possibilities of constructing, I believe I have created the very best infrared pens you can buy for classroom use. I have put these to the test with my students and the pens have passed with flying colors. I would invite anyone who would to visit my new web site http://penteractive.us and give a look. I hope to put up some videos this week of the pens in use. They are quite sturdy despite being plastic and battery replacement is very simple. Again, I welcome your comments...and orders.

A glance at the new pens.

simple = maybee

small batteries = expensive, non rechageable

no ship outside US = bleeeh - narrowminded yanks ;)


but they do looks tricky...

AG10's (batteries) are pretty cheap here in the US and really cheap from China and are actually simple to change. I put a few pens to the test with 6th grade students. The pens only showed weakening after about 2 weeks of regular use and were even dropped frequently. The button is in a perfect place and can be pressed by the forefinger or the thumb. The tricky part was building them but I found an easy workaround and...no soldering! I do use a little wire glue for one of the connections. It looks like it was made to be used as it is and not a modified dry erase marker or highlighter.

Sure it's not rechargeable but until a viable commercial alternative is available, I think these will be pretty decent. 

I just don't want to fool with the paperwork for posting internationally...sorry.

If anyone has visited my site recently you would have found out that I had run out of pens. Well I now have new stock and a brand new color - red. Thanks.

Hi John, I really like the sound of your pens and where you're coming from on this (and the price certainly is right) but I need to know a bit more about them before I make a purchase. Mainly, where is the button located? Is it near the index finger holding the pen, is it on the rear, or perhaps the tip (apply pressure to push button)? I would ask what sort of batteries it takes, but I gathered from your response that they're AG10s. You really should have a page on your http://penteractive.us/ site that breaks down all the technical specifications about your pen! You should include battery life, etc -- anything and everything is applicable (it'll only help sales if people are sure about what they'd be getting, of course).

You are very correct. :D In fact I believe I will do that right now. I'm not looking to get rich but getting a few sales would be nice. My primary purpose is to promote the whiteboard project - which my site should reflect as well. Thanks so very much. And for folks outside the US, I am going to try selling internationally. Oh boy... :-\

This pen looks nice and simple (and the price is definitely right!).  I just have a couple of questions due to the fact that I know very little about electronics.  Was wondering if you gurus could help?  I was wondering if the battery source leading to this led has enough "juice" to give it the optimal power we are looking for compared to the AAA or N batteries styles?  Has anyone done a comparison?  I was also wondering about how easy it is to change batteries and how often I would be changing these?  Any help would be much appreciated!

The "juice" issue is an issue. I do not have one of the other pens with which to compare. Changing batteries is a breeze as all you have to do is unscrew the top, take out the old batteries, and put in two new ones. A diagram is included with the pen when ordered. I'll put that on the site as well. I would imagine that a pen which utilizes a larger cell will last longer. So there is a trade off. These are incredibly easy to use and inexpensive versus purchasing a more expensive model with larger cell.

The "juice" issue is an issue.

Not really, you are using 3x 1.5 mini cell batteries, potenttially more of an over powering issue is anything. The cell size is small but with three should provide with a reasonable life span. Assuming you are using the correct resistor the current should be regulated extending battery life and most importantly extending IR-Led life.

The only issue I see is overuse of resources, the AG10 is not available as a rechargeable, and hence a large amount of waste, regardless of how cheap they are.

I actually only use 2 button cells. One is removed. Yes I'm sensitive to the fact that there will be more AG10 cells put in the trash. There are rechargeable button cells but I haven't checked on the availability and compatibility. The good part is that the technology that Johnny Lee created and BoonJin has improved upon is being tried out all around the world and people are looking for a ready-made solution to try it out. I'm filling that bill presently and I'm happy to be just a bit player.

Hello, I'm josh. I'm mainly a lurker, but decided to comment on these pens.

I tried my hand at making one of them, except via the USB power bus. Mine ended up with the IR emitting visible light :P I used the wrong resistor. After tearing up some packaging, I decided to buy from one of the guys here.

I ended up buying from Jmitchell. The shipping took a while because I had it certified so I could track it. Wrong move.. Mail took 7-9 days :P So razz on me.

I did receive them yesterday, and boy are they nice! The light totally blinds my camera on my phone, and can easily illuminate a halo in a dark room (think ir cam surveillance). He used one of those durable never-break-in-20 years surface mount buttons, with a little soft piece of plastic on top for easy writing.

I guess the battery non-recharging _might_ be an issue, but I've known no batteries that cannot be recharged. Recharging a chemical battery is as simple as providing a trickle charge and knowing how much power it holds vs how much you've put back. LiIons do the same thing. That's why they have a regulation circuit watching input and output. LiIons can also be shocked into working from "the grave".

As for the software, we have dialup, so getting the C# and DirectX libs for running johnny's apps were out of the question. Instead, what IS in consideration is a mixture of Linux with MPX, WiimoteWhiteboard and compiz. I can have multiple input devices controlling multiple mice and multiple keyboard inputs. This setup is just like Surface, but it works with all older apps, along with newer.

His pens are quality, and the Linux software kicks serious A.

All the best.

John I love the look of your pens and I think they will work great in a class room. I have also received a lot of response to the pens I have been selling. www.thetechguyusa.com/shop . I have been shipping internationally and could give you pointers on how to do so. Good job on your pen keep up the good work.

You are both producing an awesome input into taking the Wiimote IWB to the next stage. I am keen to get a forsale section running, with some fairly explicit controls to stop the bullsh** that forsale threads can produce.

Could you both comment in the http://www.wiimoteproject.com/comments-and-feedback/bst-section/msg5793/#new thread of how you as sellers see a forsale section operating within this forum.

Hopefully then we can come to some consencious and convince DICE to allow it.
