The Brain Stimulator is a product born out of frustration with the lack of Transcranial Direct Current Stimulation (tDCS) devices currently available. Being self-proclaimed “Biohackers,” when we first learned about Transcranial Direct Current Stimulation, we couldn’t wait to try it for ourselves. However, when we looked to purchase a pre-made device, we realized that we would either have to spend over $300 (infeasible on our college budget) or settle for a very basic model that had no ability to adjust current, let alone an On/Off switch. After dedicating an exhaustive number of hours to researching Transcranial Direct Current Stimulation, we realized that it was possible to build a device that would encompass everything that we wanted to see from a tDCS device, without breaking the bank.

So, we set out on a mission to create a new standard for the industry.

Our very first logo

After going through prototype after prototype, constantly revising and improving the circuitry, and testing every device to ensure that it performed up to our high standards, we finally landed on a design that we believed was ready for market. For the first few months we didn’t even have a name for our product. After trying several names that just didn’t fit, it hit us! All of our friends and family kept asking about “that brain stimulator thingy” we were working on, and so finally we decided to call our device, “The Brain Stimulator”. With our new name and a product that was starting to take off, we realized we had started something really amazing. We continued to examine the design and functionality of our products to determine where improvements could be made, and what possible future features could be implemented. Since the first device we brought to market back in 2013, we have changed the design and functionality of The Brain Stimulator more times than we can count. We are completely devoted to producing not only the best quality, but the best functioning tDCS devices available.

We want everyone to have access to this incredible, life changing technology. And it really is life changing! We pride ourselves on providing stellar customer service, and we want you to love our devices as much as we do. So if you are not happy with our products for whatever reason, let us know and we’ll take care of it. We also invite you to read some of our reviews and testimonials submitted by actual customers, to learn more about our products and our company.

The Brain Stimulator

We put a lot of work into The Brain Stimulator to make it the most reliable, straight-forward, and easy-to-use tDCS device available, all while maintaining an affordable price point for our customers. In an effort to help you get started with tDCS as quickly as possible, we packaged our flagship tDCS device into three different purchasing options:

Our Basic tDCS Kit includes The Brain Stimulator tDCS Device (showed below on the left), and a pair of Alligator Clip Adapters for connecting the device to home-made sponge electrodes. This “Basic” Kit is for those who are on a budget, but still want to try tDCS. Making sponge electrodes at home is fairly easy, and additional information can be found on our Choosing Electrodes page. If later on you decide that you want to upgrade to professional-grade electrodes, we offer adapters that allow you to use the device with all sorts of different electrodes.

If the Basic Kit feels a little too basic for your liking, we also packaged The Brain Stimulator into a more “advanced” kit combination, aptly named, The Brain Stimulator Advanced tDCS Kit! This upgraded kit comes with The Brain Stimulator tDCS Device, a comfy blue elastic Electrode-Positioning Headband, and gold-plated Banana Plug Adapters for connecting the device to Amrex Brand Sponge Electrodes. Amrex Sponge Electrodes are the most popular tDCS electrodes on the market, and are touted by many as being the best electrodes to use with tDCS. In addition to the headband and adapter cables, the Advanced tDCS Kit comes packaged with either 2×2″ or 3×3″ sized Amrex Sponge Electrodes. Curious as to the differences between the two electrode sizes? Ultimately it comes down to user preference, but you can read about different electrode sizes and so much more on our Frequently Asked Questions page.

After much demand from our customers, we finally decided to add one final kit into our line up, The Brain Stimulator Deluxe tDCS Kit. This is by far our most complete, all-inclusive tDCS kit, including almost every accessory we offer. Included with our Deluxe Kit is The Brain Stimulator tDCS Device, our comfy blue headband, gold-plated banana plug adapters, and 3×3″ Amrex Sponge Electrodes. We also included our other electrode-positioning headband, which features an adjustable strap, and is large enough to stretch over the electrodes, helping to wick away moisture and prevent dripping. Additionally we included one of our Duracell Procell 9-volt batteries so you can get started using your device as soon as it arrives. On top this, we added a Saline Solution squeeze bottle (with mixing instructions on the back), as well as a 10-pack of Amrex 3×3″ replacement sponge inserts, so that you’ll always have extra on hand when your original sponges need replacing (see our FAQ page for information on replacing sponges). With all of these accessories, how will you carry it all? We’ve got you covered. The final item included with the kit is a large, soft, drawstring pouch perfect for taking your device and accessories on the go. The Brain Stimulator Deluxe tDCS Kit has grown to become our best selling tDCS kit, and our customers say they absolutely love it!

Our newest addition to The Brain Stimulator family of products, is our tDCS Travel Model device. After nearly 7 months of Research and Development, on February 20th we proudly introduced The Brain Stimulator Travel Model to the public. The response has been overwhelmingly positive, and at a price point of just $55, this device has introduced tDCS to a whole new segment of individuals whom may have wanted to try tDCS in the past, but still found the cost to be infeasible for their budget.

The Brain Stimulator Travel Model
The smallest, most affordable tDCS device

Not only is The Brain Stimulator Travel Model one of the cheapest tDCS devices currently available, but it is actually the smallest, all-inclusive, current adjustable option currently on the market. Packing so much power into such a small enclosure was by no means an easy task. Measuring just 3.25 inches long and only 9/10ths of an inch thick, The Travel Model easily fits into even the smallest of pockets, finally providing for a tDCS option that can literally go anywhere with you.

Along with the ability to select between two different current output levels, The Travel Model is our first device to feature a detachable electrode cable for convenience, and maximum portability. In keeping with our original standards, The Travel Model’s electrode wiring features the same connector pins as The Brain Stimulator. Just like The Brain Stimulator, we have also packaged The Travel Model into both a Basic and Advanced Kits.
