Good to hear from you Gerri.
Thanks for the feedback Johann!
No you would not be able to change the CD-ROM firmware, you will need to add a custom microcontroller to add the functionality you need.
Yes, the stair lighting kit can work with dry contact devices such as motion sensors and under carpet pressure sensors. Please see page 35 of the manual for details.
You will need two additional resistors which can be found here http://alan-parekh.vstore.ca/components-resistors-c-12_13.html
The beam needs to be mounted on opposite sides of the stairwell to work properly.
If you are looking for a system with more features please have a look at the Reactive Lighting system.
The IR Jammer is a device that overwhelms an IR detector so that normal commands can not be received.
Glad you liked it! Thanks for the promotion to your friends.
Yes it looked great. It was just featured on Hacked Gadgets though and was not made by me.
I would recommend a PICKit 2 or 3.
You can see on this page how the PCB connections are made.
This project shows you the step by step process of using one to power an LED.
This sounds like a project on Hacked Gadgets. Most of those project are just featured there. Please check for a link within the article for more info.
Sorry, that project was done long ago and unfortunately I don't have the code for it.
There are long range ones but I am not sure about 100 meters.
Great! Let me know how it works out.
