Sorry for the big gaps in the project log. There is just too little time to document everything while working.

So since the last post, there has been a second revision of my PCB. I changed some small things and added LEDs and a MEMS (gyroscope, accelerometer and magnetometer – to be able to turn of all motors when glove is not in regular position). It all worked out quite well, and just in time for the trial I had all 4 prototypes (2 sizes, one spare glove each) ready. You can have a look at the photos for details for now. Of course, I will upload material, blueprints and code as soon as I had time to put everything in order, probably in February when the thesis is finished.

So after finishing the prototypes I was able to successfully conduct the study in August and September without any technical problems or other issues. I also attached some pictures from the study – thanks for the photos to Kjell Wistoff.

Right now I am doing the transcription and analysis of the data gathered. In the next few months, I will write my master's thesis and submit it at the end of January. The thesis will be open access and therefore be uploaded as well. A paper on the study is also planned to be published. More on this as soon as there is solid news.

So far for now...
