According to Instructables/reddit user quicksilv3rflash…
This device can be used for any kind of human electrical stimulation, such as tDCS, tACS, tRNS, or tVNS. Its hardware, when properly constructed and tested, limits output current such that -2.1mA < output_current < +2.1mA , based on the 2mA safety limit recommended in these published guidelines.
Lew Lim, the founder and CEO of VieLight is seen explaining the device in the video.
The technology is called transcranial and intranasal photobiomodulation (PBM). Initial, small-scale results, are promising.
Five people, with mild to moderate Alzheimer’s, used the headsets every day for 12 weeks. The headset frame, with four different LED cluster-heads and an LED that clips to the inside of the nostril, was turned on for 15 minutes a day.
After the three months, neuroscientists noticed some patients, who were not able to speak in full sentences, could now put sentences together. Patients also experienced improved sleep and reduced wandering.
Each day for two weeks, Bennett would don a headband equipped with moistened sponges and attached to what she called a “big cellphone”—a tDCS stimulator. When she was ready to start the session, a clinician would give her a four-digit code to enter on a keypad, and the current would surge through the wires and into her brain.
Robin at Caputron sends word of their new ‘exclusively from Caputron’ ActivaDose 29V 2mA max Iontophoresis device. My one caveat with the ActivaDose had been the potential for user error in choosing a 4mA setting (rather than the 1 or 2mA setting traditionally used in tDCS research). This new device removes that possibility. This is the device you could confidently show your Mom how to use. The new version maintains the ActivaDose FDA approval for iontophoresis. This new version becomes the device I can recommend in all confidence, also because Caputron stands behind all the products they offer.

Badran, who used two different mindfulness scales and mood rating scales on 15 participants in a double-blind study, found that feelings of calmness increased almost 2.5 times in the group receiving active tDCS-paired meditation compared to the placebo. Individuals receiving the sham stimulation had just a 5 percent increase in calmness rating.
Update 2/2/17. Focus just announced functional Near-InfraRed Spectroscopy (fNIRS) capabilities for their EEG Dev kit!
This was announced a few days ago and to be honest, I wasn’t sure what to make of it… a battery-looking EEG thing. Certainly I’m not a ‘Dev’ and so I left it to those who are to parse the details, still… Ah, yes, further details arrived today via email I’m happy to share with you (below). I do get the feeling this will make EEG devs excited.
Update 1/19/17 The focus site now has a photo of their new dry EEG electrode.
Thanks for all your feedback and questions about the focus EEG. A common question has been what exactly is included (see below) and is it everything required (yes).
Included in EEG Dev Kit
foc.us EEG 24-bit 8-channel EEG with tES & Wi-Fi
8 active dry electrodes for EEG, plus bias & reference electrodes
2 active bio-potential electrodes for ECG, EOG, EMG or EKG
2 wet tES electrodes for tDCS, tACS, tPCS or tRNS
10-20 placement cap
Mains power adapter for recharging
Raw data access
Next week we will provide more details on the software and SDK for EEG processing.
P.S. The first 100 66 are available at only $999 $499 – half price!
What I’m excited about is the Focus EEG headset, but a recent tweet exchange indicates we’re a good year away from release.
In South Korea, Ybrain is betting that these benefits and its slick consumer-friendly design will speed adoption of its device. “It’s designed for home use,” says Ybrain CEO Lee, “so physician can electronically prescribe the device and patients can bring it to their homes.”
Do not use the “Oreo Cookie” approach where you soak your sponge in your saline solution and squeeze it to remove the extra. Because it over saturates, it’s dripping, it’s very “subjective” and hard to reproduce. Get a syringe and put 8mL of saline solution on your sponge and make sure to also get the corners. Do that prior to insert the electrode in between the 2 layers. If it’s dripping wet, that’s bad (you’re doing it wrong!). You should not have to use a tower on the patient’s neck.

Analysing these high-standard studies revealed that tDCS seems to reliably improve the symptoms of depression, addiction and craving, and fibromyalgia. It also uncovered that the technique does not work for tinnitus, and that the evidence for using tDCS for stroke rehabilitation was not as strong as many had thought.
