Hi William, AJ, and all involved, Thanks for your feedback. I downloaded the beta but immediately faced a problem with the hub: (error message) A JavaScript error occurred in the main process Uncaught Exception: Error: Cannot find module 'openbc…

Hey guys, We will be joined by Jack coming all the way from Magdeburg and he asked if it were alright to meet at 7 or 7.30 pm instead of 8, because he will have to catch a train back by 10. So I will be at the bar at 7 pm, feel free to come earlier…

Thanks guys! So it shall be April 18 at the 3 Schwestern in Kreuzberg. Is everyone fine with 8 p.m.? Cheers, Derek

Hi Ulf et al., The place looks great! Unfortunately, I just realized that I messed up and can't make it this Wednesday. Would it be alright to postpone it one week? Otherwise, I'll be joining on our second gathering ;-) Cheers, Derek

Hi all, So, we have a small but exquisit group of 4 (with jeyem maybe five) participats by now - maybe my lady will be joining, too; after all, it's her who is trying to run polysomnography on Alpakas, not me. I'm merely the technician here. Judgin…

Oops, I completely overlooked your last message, @ulf2us. Sorry for not reading my emails properly. But great, sounds like we're actually gaining momentum :-) I set up a doodle, called Brains N' Beers (and yes, wine drinkers are welcome), to be fo…

It all brews down to beer..! Yes, it was very cool - but to give credit where credit is due, the problem-solving was basically accomplished by @wjcroft and Ulf and I were just dividing work... "So you hold the jumper cables really steadily to the co…

Hey @pushtheworld, thanks for the hint! Ulf and I actually got together last week and were able to aid one another to overcome our technical difficulties, so that almost makes us a tech group ;-) And I do recall Ulf visiting the neurotechx-website. …

Hi William, I am happy to report that it worked! I got the breadboard, cables, etc., soldered the header pins to the dongle, built the circuitry according to the instructions and was able to flash the RFduino firmware. And now i have a very beautif…

Hi William, Well, I could get the RFduino USB shield for some 30 bucks on the internet (2-3 weeks delivery) but unlike in the tutorial, it comes without capacitor, so there's not much of an advantage here. Alternatively, I can walk over to the near…
-
That's the tutorial that I had been using. But in the "UPLOADING DEVICE FIRMWARE TO CYTON BOARD" section it is presupposed that you have a lot of extra material (either a third party FTDI board and/or a breadboard, a capacitator and jumper cables) w…
-
If I unterstand you correctly, it is assumed that I already have all the cables that are necessary, i.e. that they were included in the shipment. Oh dear... I will have to go searching... :-) Thanks again!
-
But wait a minute... I still need the extra tools (serial connection cables) to directly connect my Cyton in order to flash the onboard RFduino... no?
-
Aha! I followed the instructions on the OpenBCI tutorial (your second link) and went straight from V1 to V3, skipping V2. Additionally, I flashed the board first and then the dongle and then couldn't flash the device. Unfortunately, I hadn't come ac…
-
Just one more question: I managed to downgrade back to HOST 1.x.x and now the dongle and Cyton reestablished communication (with all the artifacts motivating my original post). But the connection is fine for Arduino and programming the board itself…
-
Hi William, Your intuition seems to be correct. Even though I was pretty sure that my firmware update had also included the dongle, I was apparently mistaken - I found no trace of previously having downloaded the pertinent files for the dongle. So…

Hi William, Thanks for the rapid reply! That's weird, I can see the images in my thread. But I'll post links here: image one: no electrode connected https://www.dropbox.com/s/hmod1bpofzyi8t6/No_electrodes.png?dl=0 image two: electrodes connected…

Quite a coincidence... I just set up my own user account to submit a post about my technical problems and the first post I see is yours, being only minutes old. I'm Berlin-based and would never reject a nice chat that comes along with a beer. I have…
