Pahom, thanks for your reply and encouragement. The Contraption seems to work as is but I just need to find out if the ToTeM receiver will work better (actually some sort of hybrid). Honestly that computer generated stripboard looks like near impossible for my eyesight and somewhat shaky soldering technique. I lost count of how many jumpers on that board, nearly 70, so times two that is a lot of soldering right there. I'd never get it working because the strip board peels apart when doing repairs, at least at my skill level. I wish somebody had a PCB to sell, but for now this project is just experimentation so I don't care how pretty it doesn't look.

Good evening zakari. On the printed circuit board, you need to bring the power minus to the first leg of the timer 555 (U 7) according to the scheme.

Yeah, sorry I missed it. I'll add a jumper .it's a thin conductor.

Hi if you know, the Instructable of the two coil in front of totem and the coil in ferrite is the same 870 mH ? THANKS

The inductance of the RX coil is 870uH (not 870mH).
The inductance of the TX coil should be around 916uH.

I want to know about the people who built the TOTEM, if it detect a spark of a battery 1.5V and at what distance ?

it's not just a question of sensitivity , i removed the comparator , it's a fast pulse extender and display !

TOTeM is capable of detecting the spark from a 1.5V battery several meters away (not just 1.5 meters). Also, an old style CRT television can be detected from 6 meters.

did you detect the battery spark several meters away with or without the transmitter or stimulator ?

At first my Totem does not detect the spark, and when I change the comparator and the audio, I have succeeded !

Spark detection does not require the transmitter to be operational. You can detect it in passive mode.

Hi my friend qiaozhi what's the best frequency for totem and what are the best changes to this machine and what is the loop making?

Default Heathkit sensitivity

Dear Qiaozhi
Do you think that Heathkit's sensitivity is comparable with the circuit receiver that you have made for the totem pd? I would like to build the heathkit with the omega coil system but by using your circuit. The only doubt i have is the fact that heathkit has a regenerative feedback and i am not sure if the opamp solution can reach heathkit's sensitivity. What is your opinion?


Thanks
Jeg

The Heathkit GD348 detector is very old and not very sensitive, even with its 10" coil.

It is also important that you understand TOTeM is an experimental PD designed to investigate the claims of LRL proponents, and that there is no accepted scientific theory to back up any claims for this type of device. It's main purpose is to give you an opportunity to explore the pseudo-scientific world of LRLs, and make up your own mind on the matter.

Thank you my friend! I am also a sceptical experimenter as i have built a ton of LRL's the last 10 years. But i always wanted to put a finger on Alonso's pd, and your circuit looks perfect for that. Simple and reliable.



Thanks
Jeg



ps. I am looking forward for the Arduino nano totem version.

this project is a complement to the alonso pd circuit, i think it could work in the old days, needs testing..someone post the results in the group!
