Need Help: How to Make a Two-Way Radio/Push to Talk Integrated System

[delenn]

Hi
I am a student doing a toy design project.
I have to find a way to build a radio circuit for my toy, a walkie-talkie helmet.
I basically have no electronics experience whatsoever, so I hope that I can get some help with this.
(I can solder, I have worked with resistors, transmitters, etc., but I have no clue how to make something from scratch)
(Previously, I took two old walkie-talkies, gutted them, and glued them on to my helmet for functionality purposes. Now, we must make a full prototype, so it has to look nice and work well.)
How would you go about creating a two-way radio system with little experience and a tight budget?
Thank you very much.

In one post you mentioned 3 times that you have no experience and no clue how to make this project.

Most of the things in this world cannot be done, if have no clue how to do them.

Wow. Well, because I simply cannot refrain from responding:
1. Yes, I would say I am inexperienced within the world of electronics, but that really has nothing to do with the premise of my post. I was asking people what they would do if they had to build a radio system, which would help me pinpoint a starting point in my project.
2. If people were to not try new and unknown things, there would be no point to living, because life would not progress. Its something called "LEARNING", I'm sorry if it is too advanced of a topic for you... That might be the stupidest comment I have heard in a while. Congratulations.
3. Thank you for wasting my life and your life by replying in the most unhelpful way. So much for asking for help in an area I have yet to learn. (I'm more mechanically inclined anyway)


Thank you so much, Oh wise "Advanced" member! <----sarcasm, just to make sure you understand


Rant Over.

If anyone else would like to give me advice about my radio project, I will greatly appreciate it!
I am much kinder to people who are actually helpful! :grin: <3

Hello!

If it's made with a plain toy-like walkie talkie (which is basically one way), then it will be difficult to make it
two-way. Now if you can do some mechanical trick to your helmet to switch "manually", then it could work.
For example, if it's a bicycle helmet, then you can easily replace the speaker by 2 earphones, then replace
the switch by a cable and a switch on the handle. In this case, you need almost no electronics knowledge.
Otherwise, I can't imagine a smarter solution.

Dora.

I think vfone was right. You mentioned that you have no experience in this topic and low budget, and he gave the correct answer: under these conditions you can't build your own radio from scratch in a few weeks, by asking some questions here. It's not trivial even for most EEs whp learned about electronics at the university for a few years. If you know the topic, it will take a few weeks minimum to build such a solution. More likely: a few months. And you will need some RF measurement equipment to do it right.

So how about giving up the "froms cratch" requirement and use partially pre-assembled transceiver kit solutions from amateur radio? The aren't applicable because of wrong frequency range (don't operare in the free unlicenses bands). So not a solution either.

So how about the radio modules we can buy? NIce for data, but usually not applicable for plain audio.

What's left? You could get a set of unlicenses handsets (PMR or so) and use their electronics. That's something you can do easily in a couple of days.

First, thanks Volker for clarification of my point of view.

Most of the "Advanced Members" on this forum got their title helping other posters, and I can assure you that most of the time is about helping inexperienced people.

If you ever think that I will argue with your sarcastic point of view, you are totally wrong.

each country has its own laws about transmitter frequencies, I dont see how to help without knowing where you are ?
