I’ve always wanted to try TDCS, AFAIK the only way currently for recreational use is to DIY the setup. This freaks me out, fiddling with and possibly bricking your brain is not like hacking an e-ink store label or Philips toothbrush.

I think the best way for brain hacking (other than drugs) may be Altman’s Brain Machine, which works by modulated light pulses, Adafruit used to sell kits but it should be easy to build one yourself: https://www.adafruit.com/product/287, https://makezine.com/article/home/build-a-brain-machine-wit/
