Recurring artifact pattern on WiFi Shield + Cyton. Happens whether powering WiFi Shield with 6V AA battery pack or 3.7V LiPo. Happens regardless of sample rate (250, 500, 1000). Does not happen when u

Question 2) I've also been told that some of the issues with the WiFi Shield can be resolved by avoiding the 3.7V LiPo battery and instead using one, or even two, AA battery packs.

batteries (brand new) as well as i single cell LiPo battery. None of those seemed to make any difference. I have also tried it on 2 different PCs with the same results.

Diego, please try using TWO batteries, one each on Cyton mainboard and shield. This was mentioned in previous posts on this thread. Also suggest using AA cells vs. LiPo.

re: your power supply related artifacts: did you try the suggestion of Jason (alwayswearshats), to power BOTH Cyton and Shield from at least 6V power packs? This would reduce the power glitches becaus

Whoa. I just plugged in a fresh battery (LiPo) and for the first time ever, the 'OPENBCI BOARD' query returns 'Cyton'. Whereas previous attempts it returned 'none'. Alas, when I hit 'Start Session' I

Has this Wifi Shield EVER worked correctly for you? As a reference, people seem to have better luck using two batteries, and non-LiPo configurations (which generate higher voltage, 6V vs 3.7V).

Where are you getting the 9 to 12 hour figure for a 6600 mAh LiPo? Previously I mentioned:

@wjcroft Hi. Here's a link of a video about how potentially dangerous LiPo batteries are:-

I still recommend the plain LiPo cells from Adafruit. Simple, and you can use with the charger they sell.

Regarding the LiPo, I would not recommend using one with the Cyton+WiFi Shield as there is not enough voltage headroom. I still recommend using 4 AA batteries. It's a bit awkward but I superglued a 4x

No, the battery (AA pack or LiPo), is strictly DC only. Cannot generate any noise in your signal. In a typical Ultracortex setup, the LiPo cell is right next to and touching the back of the Cyton or G

Have you tried using a larger LiPo cell? It's best to run from batteries for both safety and power purity.

Thanks techsupport. I ordered the LiPo Battery. 

if this helps but the easy fix is getting this LiPo battery or making sure you have plenty of AA batteries and switching them out regularly.
