Is anyone still interested in updates on using disposable electrodes? I’ve posted about them a couple of times (#284; #161); this information is still valid, but I’ve progressed a bit in fine details of technique since then. I’m trying to see just how long I can get; so far I’m up to 18 days with a single set of 3 electrodes from a long-open pack of outdated disposable electrodes, and they’re not (quite) dead yet. Personally I’m happy with disposables, and not having to try to make or acquire headbands; and with this lifetime they’re not at all expensive. Possibly more people “out there” will persevere with Zeos if they know that they work with electrodes that are easily available and inexpensive (if they hear abut it). I don’t come here all that often, but if there’s interest I’ll write up some further details next time (electrode lifetime testing takes a long time). Techniques: Hypafix 5cm tape, Tensive gel (optional, for ~double life), and a moist finger (optional, for a few days longer life).
