Combining different metals in a single electrode is not a good idea. The usual reduction/oxidation cycle used to transfer current from the electrode to the skin doesn't work well when there are dissimilar metals, resulting in rapid corrosion.

Yes. I don't know why I said console, I meant teleplot. Ok, I got it working now and I see all the waveform in teleplot. I did a quick real life test with the same trodes and placement but so far I am not getting the right calibration (TBH neither on DIY box is perfect ). BTW I read many times the ...

No there isn't. Should add it, since creating a shortcut with a path to the config file is much more elegant than copy-pasting the executable, the current behavior is to always load the config file from the current working directory.

Thanks for the feedback on the funscript conversion. It took me a while but I added a checkbox to the funscript conversion dialog to enable/disable the random direction changes. It's easy to change the mouse wheel step increment. I like the way it works now because I use the arrow keys and pgup/pgdn...

The FOC-Stim cannot play audio files, it can only play funscripts with Restim. It is possible to implement (some form of) audio playback, but don't expect this soon. The main advantage of the FOC is current control. Meaning that minor changes in skin contact, skin moisture, body positioning no longe...

Yes. I don't know why I said console, I meant teleplot.

I finished building a FOC-Stim yesterday, and I'm really impressed. Thanks to Diglet for sharing this creation and the excellent Restim app with the community! As others have mentioned, it feels much smoother than traditional stereo stim, is a fraction of the size and cost, and is nearly silent (un...

I finally got around to a second attempt with everything soldered properly. The R_neutral/left/right stay at 15, even when I play a signal. I'm not sure what you mean by shorting the outputs. Just connect the leads? The pot is set to 1. Yes, connect all the leads together (at low volume), the R_ va...

Good catch, I just fixed it.

The center output on the board is the neutral/common, and the one closest to the onboard potentiometer is the right.

I finally finished assembling my box. Every step has been completed to the best of my knowledge, but I can't for the life of me, connect it to Restim. I see a message in teleplot saying 'V-BUS too low: 4.74', and after plugging in the 12V, I get 'V_BUS online. V_BUS 12.16 status: 3'. In the FOC-Sti...

Thanks for the feedback. I've been seeing more people hitting the current limits, I think I made the limits a bit too low for some electrode placement and/or bad boards. I increased the current limit margin from 0.2A to 0.3A, reduced the minimum resistance from 0.8 to 0.7, and also expanded vbus an...

Hi, just started to work on this, I got the firmware built and updated. It looks like it connects restim but the LEDs do nothing Is there a way to check if the board is working without connecting coils, transformers, 12v power supply etc? Not really, the software doesn't do much without connecting ...

I haven't seen this before. Can you send me the funscript files so I can investigate?

I have been told that low frequencies are not good or unsafe for DIY stereostim, I dont know if this is accurate. I did notice that LOTS of this channels stuff is in that range. If you ask the internet, they're like "what? tens units have low frequencies. Whats the big deal?" I'm new enou...
