I am a longtime fan and proponent of tDCS. There is plenty of evidence that this simple, safe, technology can be used to reduce or eliminate depression, treat chronic pain (including migraine headaches), enhance memory and learning, and more! If you are new to tDCS, take a look at the index of tDCS articles I’ve posted at https://speakwisdom.wordpress.com/tdcs/
If you are looking for a high quality tDCS device that also happens to be ideal for summer travel, you should consider “The Brain Stimulator Travel Model”. This is a well-built, basic, tDCS device that can deliver 1 or 2 mA with the flick of a switch and can stand-up to being repeatedly tossed into a suit-case or travel bag, jostled around, and still come out ready to go and deliver a reliable tDCS session. Depending on the configuration you buy, it can cost as little as $55 – or a bit more with high quality electrodes and other accessories.
The Brain Stimulator Travel Model also makes an excellent first tDCS device or a supplemental device if you already own something more sophisticated. It is built by JD Leadam and his team at Neurolectrics – real pioneers in the DIY tDCS marketplace.
(The packaging of the devices is simple, neat, and able to withstand travel related abuse.)
Neurolectics used a tried and true design built around a current regulator and a 9 volt battery. It’s simple, safe, and reliable – but because a 9 volt battery is used as its energy source, it is very important that sponge-electrodes be used and that they be well wetted with a saline solution in order to assure delivery of 1 or 2 mA (depending on switch setting).
I always prefer that a DIY tDCS device have some monitoring capability (digital or analog meter) to assure that the desired current level is being delivered. Neurolectrics chose not to take that path with this device – I assume to keep cost at a minimum and the package as small as possible. If you are a frequent tDCS user, I’d suggest changing the 9 volt battery every couple of months – and again – be sure to use well wetted sponge electrodes to help assure you receive the selected stimulation level.
(Neurolectrics places all significant components on a nicely manufactured PC board. This limits point-to-point wiring and makes for a more reliable device – important for a travel device.)
The Brain Stimulator Travel Model could not be easier to use! Simply wet the electrode sponges, place the electrodes as desired with a headband, flip the switch to 1 or 2 mA, and begin timing your tDCS session (20 to 25 minutes is typical.) When done, switch off the device, take off and stow the electrodes and you are done. If you really are traveling with the device, I suggest you remove the sponges from the electrode shells and place them in a small water-tight container. You should also wash them frequently with good soap and plenty of water to prevent anything undesirable from growing in them!
I’ve taken several trips (including through airports and airport security) with the The Brain Stimulator Travel Model and found it to be quite handy for personal use and for demonstrating tDCS as seminars. Don’t expect any flashing lights or fancy meter with this unit. It’s basic tDCS – and it works.
