Hi, another project idea (building it for my kid nephew), I was recently looking around and thought "screw it with walkie talkies", why not make him a home made set of German field phones.
My idea is just a hand set, a switch to switch say on and off, and maybe if it's too hard to have 2 open lines, just a switch to go back and forth between hand sets. I'm fine if it's battery powered (which I'm guessing it probably has to be), maybe 1000 yards transmission (the german ones run on D batteries and can go up to a mile) , any idea would be great, thanks!
awesome idea, any idea of what I'd need? I gather that I'd need a different kind of handset, any idea on how much these will cost? and do you know distance that will be covered with these?
This idea seems interesting if you can gather two old telephone sets. So the total cost will be less. I've found two articles for this simple set up and they says it'll work serveral miles apart. The second article provides external ringing facility as the inbuilt phone ringer needs 90V/20Hz accurate AC voltage. **broken link removed** **broken link removed**
