I am building a lasertag system from the ground up. Actual gameplay mechanics will be based on the Halo video game (shields that recharge, but only if you are not killed and have not taken damage for a certain period of time, "armor" that includes an lcd display to act as a shield gauge, as well as a piezo buzzer to act as a shield alarm, etc, etc). It is based off of the arduino uno. I already have the code written for it, broken into 3 pieces, each of which is executed on a separate atmega328: the "core" which controls the LCD display, the piezo, and other aesthetics along with storing the value associated with shield strength/health. Second, the "receiver" determines if the player has been hit, and tells the core when this happens. third, the "rifle" deals with shooting the laser, keeping track of the number of rounds in the magazine, and making some sort of gun noise.
(this is probably not the most elegant solution for this purpose, and if you want to make recommendations on the basic layout of how it works, im open for it, but this is not my major concern right now)
The major issue I face now is the sensor pads. I cannot figure out a reasonable way to detect a small dot of visible light somewhere on a large surface area. (I do want to use visible light, not infrared)
The "receiver" reads an analog signal from the sensor pads and converts it to a digital signal that corresponds to an interrupt in the core program.
>>This is important because it does not detect a signal, but a change in ambient light intensity relative to a calibrated value. It is not meant to receive a digital signal directly.
I have several different approaches, which I will outline in following posts. (too many characters)

Tis almost the season, what are you /diy/ing for Christmas?
My wife used to do archery, but done so in years. She's been looking at them online for months, so I'm making her one, made from PVC. Been experimenting with the materials for the past few days, it has surprising results. I'll show progress of one of the demo models, I'll be building hers once I got decent results from the demo model.

So, I have a 10" speaker element that I'm gonna build a box/enclosure for. Do you have anything to help me with regarding how big it should be, what materials to use, and how to do it? The element is 10.8 inches wide, and 4.3 inches deep/tall. I'll be using it my car, so it shouldn't be too big, and I'd like it to be as cheap as possible.

Hello /diy/, I need a little help.
The front door of my apartment has been warped quite badly and a lot of heat escapes through the gaps. Unfortunately, the landlady refused to replace it. With winter upon us, I really need a solution to prevent heat from escaping for obvious financial reasons.
-taking the door off is not an option
-I've already tried adhesive rubber strips - let's just say they didn't work
If you have a possible solution, please let me know. Thanks in advance.

Beer throwing fridge - Need help
3 more posts in this thread. [Missing image file: ]
At our school we have been set up to make a beer throwing fridge as a project. We have the most things in place, such as measuring sensor, remote control to activate the fridge etc. except the most important part… We want to use a spring to launch the beer, as it should be easier to control the distance that the fridge will shoot the beer, it is less compact and it will just look way nicer than a catapult (which all other groups make and the teachers give better grade for being creative, so we wanted to create something else).
This is the way we except the fridge: Beer loads into some kind of barrel --> The spring contract, to launch the beer according to the distance measured by our sensor --> User press button, fridge play sound --> The spring is released from the loading mechanism, so the beer is launched --> The spring is loaded back onto the loading mechanism, and done.
We can’t figure out how to make the loading mechanism. Any ideas? We are open for all suggestions, as long they are within our budget, and doesn’t require some heavy machinery to operate. :-)

Hey guys, Im considering modding a NERF Strongarm into something like the picture here, but to do it, I need to have some parts 3D Printed, does anyone have any experience with online 3D printing services? I was considering shapways, but I wanted to see if anyone here has used another service with good results.
Its for an insane post apoc LARP.
