I hope there is enough room to cram in a 50 hz notch filter in that amazing box of electronics to suppress all those nasty radiated noise artifacts from that mains lamp near his head! |

Is this the only thing that is weird about their device? I can't see anything that makes any sense... |

No, no no... |

I'm back! Again? Uhhh..
The most simple and cheap thing to do, is to make a PCSpeaker device, as Petr suggested. I assembled it and is super easy to do - took me 30 min. |
|
Wow, this seems very easy to make, but dont you need any oscilator to controll the waves? And how do you controll the current intensity? At step 3: Do you need to get the signal from the speaker or the board? How do you connect the cables to the low voltage end (without soldering)? Does every power adapter works? And can i use this cable (of an non-functional cheap tens device): |

As I understand, the oscilations come from the MP3 or the smartphone thanks to an audio file you can make with soundforge for exemple. |

Right now completed another test F3-F4 location 40HZ sinus current about 0,15mA (only fast test of it before sleep so value can oscilate during the sleep) |
|
I guess some form of initial ramping could be achieved by the actual recorded volume of the mp3 file used, providing the signal to noise ratio and overall quality is high, and there is no transient noise or clicks present in the recording itself. |
|
Good testing of wavefrom on osciloscope and current on metter is higly recomended you at least need measure current.Its possible use device without current mesuring but in this cas you dount have any data about used stimulation. |

If a 9v battery shorted out it could cause a fire. |
|
To 9V battery make a fire is possible but very uprobable it must shortcircut by some thin wire very close to battery ,shortcircut somewhere in amplyfiler is also possible but risk of fire is there much lower. |

I hope it is just mistype or that it's because that every member of the team not have a knowdedge on all areas but write wron mout important thing about technology |

As Kaan has already pointed out, no oscilator is needed. That's the whole point and the good thing about Petr's design: this clever setup, converts any simple audio signal (from a phone or mp3) to an electrical stimulation signal! So, all you need, is a free program like audacity, to make a 40hz sine wave audio file (if need help on this, just say) that will be converted to stimulation by the device! You can also experiment with other audio signals - eg square waves, saw-like waves and such, and also add fade-in, fade-out to the audio, that will be converted to stimulation! |

Thank you for your help |
|
Also do not do test every day leave one day pause this is beoause is stimulation couse change of sleep architecture is good have one day to recover it .Is there also chance tahat in night without stimulation can have different dream recall an LD count than normal. |
|
Yes, I know. I just had some experience with the app, and it seemed that it did a good job for me. Nevertheless, these last nights it let me down... Some of the triggering happened while I was wide awake.... |

Problematic is far more compex nobody counts with interpersonal differences for instance this can make to 100% diff in current in corex level.Size od electrode also change current in brain. few others : current path in brain , ongoing activyty , shunting effects , lenght of stimulation . This is only basic ones thre are many more. |

Today test |

Two more nights with stimulation. |

A friend of mine and I are working on reproducing the results that jeffg and Dr. Voss had. We are building an Arduino device that will output 2mA at 40hz. But after reading this thread I am a bit worried that 2mA might be too high. It even seems like 0,25mA would be too high after reading about SearcherTMR's research. Is that the case? |
