Is it possible to create music with brain waves? It's a work in progress.
You can find all of my links here : http://delicious.com/tkarches/search/EEG
An incomplete summary :
Mindwave Mobile (Neurosky)
- Retails for $99 (Brainwave Starter Kit)
- Works with Mac, Windows, iOS, Android
- A number of iOS apps (search iTunes store with "neurosky") - most cost $$$
- Brainwave Visualizer (Mac, WIndows) shows all brain frequency bands - almost too much data
- Neurofeedback software
- Developed by the military to help soldiers
- Runs on Android devices
- Most input devices supported are based on Neurosky headsets
MindFlex and MindFlex Duel - Toys by Mattel that use the Neurosky electronics. Only uses Attention parameter. Headsets can be modified for full EEG output. These are available relatively cheaply on eBay and Amazon (around $50)
Muse - no product has shipped as far as I can tell - currently taking pre-orders
Melon - another EEG headband, shipping Summer 2014
Bitalino - not for EEG, but is a set of physiological sensors for EMG, EDA, ECG along with a light sensor, an accelerometer and an LED. Can be split up into individual modules. Cost is $150 Euro.

While the internet is a great resource for finding music, being in a record store provides a much better experience for serendipity. I really miss record stores. I used to stop at the old Record Exchange at least twice per week. I loved their $1 bin. You can take a chance on a $1 CD like you would never would for a $15 CD. Some I bought because I liked the cover.
I need to make the effort to go down to Schoolkids records once/week and buy something there at least once/month, or pretty soon it won't be there.

I investigated the differences in coverage, and AT&T's 3G coverage is slightly better than T-Mobile's. Interestingly, T-Mobile's Edge (2G) coverage was slightly better than AT&T.
Having done this, There are other carriers (MVNOs) that will let you "bring your own phone", so your options are not limited to T-Mobile. Understand that these MVNO carriers use the infrastructure of AT&T and T-Mobile, so your coverage will not get any better than it would be with either of those carriers
I have some observations and suggestions for those that may want to consider changing carriers :
- If you are planning to use unlocked phones, make sure you can get them unlocked. AT&T policy is that they will unlock iPhones that are out of contract with no outstanding charges (including ETF fees)
- Carefully calculate your ETF liability. Payback is much longer if you have a substantial amount of contract remaining.
- As contracts on your phones expire, get them unlocked, then test with a non-AT&T SIM to confirm the unlock
- If you wish to keep your existing numbers, initiate the change process at the destination carrier. If you cancel service for your existing phone lines, the numbers will go back into the pool of available numbers
- As for timing, I would switch less than a week before your billing date. This will minimize the time you will have to wait to close out your old account. If you will need to pay ETF fees, the unlock process may be delayed until the final bill was paid. I mistakenly switched a few days AFTER my billing date, and had the potential of having that third phone unusable for 3 weeks. Fortunately, AT&T was cooperative and performed the unlock once I called them to explain the situation. I did have to call them twice, but everything was very cordial.
So far so good. The only thing I miss so far is being able to forward emails to SMS. Setting this up in GMail involves typing in a confirmation code to verify that the destination address is valid. Unfortunately, T-Mobile's gateway cuts off the message after 160 characters and the confirmation code does not make it through.

Once installed :
- Run Tweak and click the "Janitor" button
- Click the checkbox next to "Old Kernel" under "System"
- Click the "Old Kernel" checkbox on the right, then the "Clean" button at the bottom right.
If you want to keep some of the old kernels, click the arrow next to "Old Kernel" checkbox, and they will be listed individually. You can then choose which to delete and which to keep.
