Have you tried OpenBCI? http://openbci.com/ http://openbci.com/ It's not standardized - so you'll have to make a headband yourself and choose some electrodes, but it gives you full access to all the signals. And don't worry about the 250/125Hz limitation, it can be quite easily hacked to write to SD with much better sampling rate.

Haven't heard of it. Looks quite promising. Price for the board doesn't seem to be too bad either given the ADC used. Definitely not something to sleep in, but could be an interesting time sink. Have you? And did you maybe do any nouroon like experiments with some other devices?

  Sadly, not many. I'm doing a lot of other things, being a front end developer full-time ;) I've played with OpenBCI and with some friends we tried to make it save signals with 1kHz sampling rate. No big-scale experiments so far. Two days ago I checked out Myo on a friend born without a hand, with some hopes to create a simple interface based on her "phantom limb" gestures (she has full forearm with normal enough muscles). Sadly, Myo doesn't allow access to raw EMG signal - and my idea is to create Myo-like open hardware electrode boards to connect with OpenBCI and get some serious signals. EDIT: Regarding OpenBCI - it's open hardware, you can make it yourself for ~under $100 if I'm right.

    I'm pretty sure OpenBCI has an EMG board, called MyoWave.

      Haven't heard about MyoWave. Do you mean the Ganglion Board?

        Found it! It's actually called MyoWare: http://shop.openbci.com/collections/frontpage/products/myoware-muscle-sensor?variant=29472011267 http://shop.openbci.com/collections/frontpage/products/myowa... It's a little 3-lead EMG sensor intended for use with arduinos and the like. It's not quite as nice as the Myo (it uses sticky electrodes), but it's a similar form factor and much cheaper.
