Walkie talkie motion sensor?

Alright, so I'm sure this isn't one of those ideas that very many will get super excited about... but I was thinking it would be cool to take a walkie talkie and put a motion sensor or event a breakable laser beam on it. In detail, the idea would be while playing paintball or something similar, you could plant it somewhere... once someone went passed it, it would use the alert function on the walkie (I don't know what the proper name is for that button, but it's the one that makes the obnoxious noise when you press it).  This would allow everyone on your team to know when the other team had passed that point. So, how would I tackle a project like this?  As an electronics newbie am I in over my head, or is this something that I could handle with a little messing around?  Ideas? Thanks!

Cell phone as walkie talkie

Does anyone know whether it's possible to re-purpose old cell phones as walkie talkies? I have some "old" phones (1X Tri-mode - 1.9 GHz and 800 MHz CDMA and 800MHz AMPS), and I'd love to be able to use them for our ski club as a short range back channel for communications in addition to the radios we use when we host races. I'm assuming we'd need to get some sort of base station, not sure where or how. There are probably some laws we'd have to comply with, assuming that something like this is even possible (I'm in Canada). I'd consider activating & using them normally, but the cell coverage on our mountain is very weak and unreliable, hence this post. Any ideas on how to get something like this started? Or is it a non-starter?

Ski Helmet Walkie-Talkie Instructable Help

Hey, all! I'm new here at instructables. I'm majoring in Electronic Engineering Technology in college at the moment. Anyways, I was reading through the ( Build a Ski Helmet Walkie-Talkie; and I have a couple of questions. I posted on the topic, however, no-one has posted on it in quite a while, so I figure I'd post here. Basically, I want to use this instructable to make an Airsoft headset (more than likely 2-way). Here was my comment: "I know it's been a while since there was a comment, but I have a few questions. My friends and I play airsoft. I thought'd it'd be pretty neat if we bump-up the realism in the game with helmet (in my case a mask) to helmet communication. Now for the questions: 1. I may not be getting this, but how do you sync up the walkie talkie and the Xbox Live headset? I skimmed over your instructions, but have yet to try it. 2. Is it possible to have helmet-to-helmet communication? As in 1 Xbox headset to another Xbox headset, not to a radio. I would really only want just two headsets (for now, at least). I'm not really expecting this part to be possible with this current set-up, but any information you can give will be extremely helpful. I'm currently majoring in Electronic Engineering Technology, so I have a slight idea of what I'm doing. I thought that this would not only be quite helpful and efficient, but also great practice for the field I'm going into. Thank you for your time, Darryn" Any help on this project (and answering my questions) would be greatly appreciated! Darryn.

DIY Driveway Alert System Problem

I tried to make a driveway alert system, but it has a problem. I connected a walkie-talkie to a Radio Shack PIR Sensor using this reed relay. Essentially, when the PIR sensor detects motion, it outputs 5 V which triggers the reed relay and closes the contacts, which connects the two contacts on the walkie-talkie button, which sends a beep to the other walkie-talkie. Problem: It works as planned, except that after the motion stops and the reed relay disconnects the walkie-talkie button, it will inexplicably re-connect the walkie-talkie button after about a second, and will repeat this cycle of beeping every couple seconds indefinitely. The strange thing is that sometimes it will work just as it is supposed to, but other times it wont. Other details: The PIR sensor is powered by a 9 volt fed through a 5 V regulator so it gets steady voltage, while the walkie talkie is powered by the regular AAA batteries. I am a novice with electronics, so don't rule out that I may have made a simple mistake.

Radios emitting constant hum? Answered

I have a set of walkie-talkie radios that I keep stored in their charging base, the base is unplugged and the wire is coiled, there are no headsets attached to the radios, and they are always off, they are motorola 23-mile range radios, this information might be relevant, but here's where it gets weird. For two days one of them would emit a constant hum for about 2 minutes, then stop, then it would start again about 30 seconds later. The hum got slightly louder as you got closer, but seemed to be coming from everywhere, making it very hard to track down,  . Remember, there was no power to either radio, and the power switches were off. Does anyone know how on earth this might have occured?Because this might make a fun prank if I can figure out how it happened

Wireless Push to talk button for walkie talkie

Hi all. I would like to build a wireless push to talk switch for use with my comms set up used for airsoft. I would like to be able to put the switch/button onto my rifle (wirelessly) so I can keep hands on when communicating on the radio. Having to take my hand off the rifle to push the talk button is a pain. The only ones I can find online are commercial and quite expensive. What I hope to do is build a simple wireless switch and modify the current PTT swith to be operated by the wireles one. Can anybody advise me how to do this? Circuit diagrams or hints?

Two way intercom design for tele-operated robot

Hi,I'm working on building a tele-operated robot that will be able to send signals generated by moving your arms and mapping these to the robot arms. I'm looking to add an intercom system to the robot that would allow for the operator to speak into a microphone and come out a speaker on the robot and a microphone on the robot so send audio that someone speaking to the robot generates to the operator.I've currently been looking into VOX circuits and walkie talkies but all walkie talkies I have seen require both sides to use a headset. It would be fine for the operator of the robot to use a headset but it would be better for the speaker and microphone on the robot to be out loud. Does anyone have ideas about how this type of system could be implemented? Could I replace the PTT button on a walkie talkie with a voice activated switch kit available online?Thank you.

The switches are printed directly on the board I'm not sure how I would add external buttons to that. Also I'm not thrilled with the size and they have more features then I personally need.
