I ordered in a batch of BC547's after trying unsuccessfully to build this project with a couple of other transistor's. They are cheap and very easy to get on Ebay now, so I figured why not use the ones that Big Clive can get to work, and they work GREAT! I have made a couple of those circuits now but never had any rabbit ears left over from long long ago when we needed them back when I lived in Minnesota in 1969. So instead I simply soldered on some lengths of lacquered copper wire recovered from old power supplies I tore down for just the copper and what ever components I thought I may one day want to use.
Should be fine. The main difference between the BC547 and BC548 is that the latter has a lower voltage rating at 30V. Not a problem for a 9V battery operated circuit.
Hey bigclive looks like your circuit is designed to pick up negative changes. If you changed the transistors out, could it pick up positive changes? (Friendly ghosts... hehehe)
Hey Doc. I have made 2 of your 9 volters , the first was in a plastic box just working well. made a second one and put it Inna cardboard gift box and have in works well, put the original in the same box set up and instead of working it's a dim glow from the he LEDs touch the antenna and the LEDs go off for a bit and relight and stay on.. Sir do you know what's going on?. Thanks for your Vidios and in advance for your help.. Bob H
@@bigclivedotcom The hot glue holding them down is the only difference and the proximity to the cardboard I could think of. Now I did make sure to make the first like yours with h the length of wire left as is. The next one I shortened down and I worked so I cut down the first to fit it in the box. I knew the sensitivity from the 3 volt one you made and your comments there. This is real interesting and perplexing at the same time as 2 damn near the same was a wonder. I hope your making something with your Chanel , I do enjoy it. And anything ghost hunting I'm pleased to see. Thanks I will try removing glue then something else might come to mind. Bob.

This'll be neat to tinker with!
A good sub for the BC54x/BC55x series in the US would be the 2N3904 (NPN) and 2N3906 (PNP). A 2N2222 would also work.

I like that circuit there a lot of things could be used in that circuit, very clever there Clive. You should be a go- jillionaire by now, Tom.
Hi can chance you could tell me how to do one with a buzzer as well. And a list off all the parts. Thanks love you videos
Hi Clive. Built using 3 cr2032.Mitch neater

It only works if I move away from the antenna, not towards it. Why is that?

Hi sorry just found this video and I lobe but what do you use for the antenna?
That's a scary Christmas card T_T

You have to be careful about leakage and resistivity of materials. These circuits are very sensitive.

Interesting.
creepy and funny
i guess you could say, hes Sherlock Ohms.
