hi William, the cap was bought in 2017 June from China for $415 inc.10% student discount. Customer service was 5*s. It was shipped from China to the UK, arrived fast. I only started using it today. The quality of the unit is in my opinion is very…

of course, thanks! k

Many thanks William, looks cool - I'll PM Alex. k

Hello William, Quick update: Good news is that my friend Fredrik knows magic and fixed the board The rfduino module was broken. He found that the serial tx pin had no connection to the nRF51822 chip (broken via under the shield). Then he man…

Thanks William, Not yet. As you have mentioned/added them to this thread, I'll wait a bit and if they don't get reply here, I'll email. Best wishes, k

Hi William, My friend fixed the board, however when trying to upload new firmware to the Device, there is still the fail, fail, fail message. I don't recall dropping, damaging the board, but in case the RFD22301 is broken, is it possible to t…

Thanks William, Yes, I can see that the ADS1299 resolution and sample rate is higher than what the AnalogueRead page says for the Arduino, and probably there are other features as well. ... so much to learn k

Thanks for the tips!

Thanks William, I think I just really wanted to get it working... so I rushed into decisions I used point tip, 220V 60W on 200 Cel. I'll have to investigate what flux channel is, but I think the board might be beyond repair now: https://www.dro…

Soldering to the pads didn't work either and I think I have damaged the RESET pad a bit: https://www.dropbox.com/s/cri8mdr7ofympa2/pads2.JPG?dl=0 So, the plan now is to solder straight to the RFD22301. I guess I can connect ground from the FTDI Fri…

Thanks. I'll keep working...

Today I've tried the woodoo trick with both, dongle and FTDi Friend, updated the FTDI driver to most recent, changed all cables, changed USB for the FTDI friend, tried Safe Mode in OSX, but still not uploading it's usually this: Sketch uses 0 b…

Thanks AJ, by soldering to the pads, you mean these, right? https://www.dropbox.com/s/ruml7wb5zn8o55p/pads.jpg?dl=0

Thanks William, I'll try all of these voodoo things

Thanks. I've tried a few things, but no luck yet. Could you please check the video where I am trying to explain what I am doing - perhaps you can see the problem. Many thanks: https://www.dropbox.com/s/3ftpsiamwc43qyz/openbci2.mp4?dl=0

Hello All, I am troubleshooting, here a video: https://www.dropbox.com/sh/eaf86md9ydookr4/AADGuTQh1jhVXpfdOyNGgRAGa?dl=0 Could anyone give me some hints on what I am doing wrong? thanks, k P.s: Thanks William, I tried the OpenBCI app with the …

Hello, When trying to update the board I get this error message below. Could you help? Thanks, k Build options changed, rebuilding all Archiving built core (caching) in: /var/folders/65/7xb70t691n3_kq1m4h2npz240000gn/T/arduino_cache_277622/co…

I'd like to know this too.

Hello both, Thank you. I've tried several times, now I am considering soldering the pins to the board Just to clarify, this message below usually indicate that I am not holding the pins down properly? Sketch uses 0 bytes (0%) of program s…

Thank you, looks exciting! Krisztian

Thanks for the clarification. Maybe later you could sell it to people who already have purchased the main hardware? Just an idea. Many thank - yes, please keep me updated with your tutorial as well. // I have received an email today, that the …

This is true, I could use 7. Ideally I wanted to use more than 8 EEG + 1 ECG, hence the original Daisy question. The pulse I think is even better, perhaps is easier to set up as well. Just out of curiosity, why is it not possible to order the Dai…

Of course. Thanks. K

I have ordered a 32bit one a few days ago. Thanks for the suggestion (+link) - once I've got the hardware I'll try to hook them up with each other and probably get back to you for some 'magic dust' i.e. knowledge Many thanks, Krisztian

Thanks Biomurph. Is it possible to use another device, for instance and Arduino Uno instead of the Daisy Module for ECG with the 8 channel BCI kit? If it is possible, would I only need to change the given code in Processing? The plan would be…
