Robin is the founder of Caputron which is a distributor of tDCS and other TES devices. Here he demonstrates the Activadose II tDCS device. For reasons mentioned elsewhere on the blog, this is the device I recommend (this is an FDA approved – for Iontophoresis – device. I’d suggest the 2mA model with the 3×3 sponge set – this is closest to what most research studies use). Caputron provides DIYtDCS readers a generous discount (I also earn a referral fee) when you use discount code ‘diytdcs’ at checkout (for any product offered by Caputron). I interviewed Robin back in 2015 when he was first getting started. Check out that post here.
