I am writing a short update on the project as there was no movement on a content but on a administrative level: I applied for a research fund (consisting of 10k €) and made it to the final round. Unfortunately I got declined so I again have to look for some more money to realize a empirical study about the device. mmmmh, could crowd funding work?
The good thing is: a lot of theoretical work is now already done due to the application and I still can use it for my MA thesis..
I will keep you updated!

The Hackaday Prize winners are out! And Unfolding Space won an honorable mention for "Best Concept".
Once more I can express my admiration for the high level of quality and elaboration of the finalists' projects. I am super happy and I really feel "honored" (haha) to be among this year's winners.
I definitely know where to spend money on and I am very happy to have this opportunity and privilege to continue to work on something that exciting and demanding at the same time.
Thank for your support and also thanks to Supplyframe and the other Sponsors to make this happen.

I invested some time to make my files, schematics and instructions clearer. You can see the updated picture all over the page. Comment, if you spotted a mistake! This is my new general schematic (would you call it the same? Don't know if it is the right term...)

An finally there is my submission video for the Hackaday Prize 2019.
As always: feedback is very welcome!

In another night shift I uploaded some Instructions. Certainly this won't be the last word, things are changing all the time and I am still about to figure out the best way to build the prototype...
But eh, now I have some fancy visualizations and you maybe can understand a little better what I did here ;-) Have fun with it!

Hey folks, it took me some effort but finally I uploaded my code on Github! :-)
All the amateurish coding skills I have I taught myself. I am getting better, but what I just start to learn, is how to structure code and how to document it in a way, that others – maybe contributors – can understand it properly and fast... This upload may be a starting point, but I also know, that there is a lot more to do.
Hope you can find your way through!

Another short Log on the busy way of reviewing and documenting all my work. (Next Log will be about the code, promised)
I wish to have just one cable and therefore one plug to connect between computing unit and glove. But as I need 8 wires (2 for power consumption for the motors, 2 for i2c and another 4 for USB 2.0 fro the ToF camera) it was difficult to find a standard with a handy, small plug and socket... Therefore I just used a HDMI micro cable – Neat idea isn't it? Nope!. It seemed to work in the beginning and I could successfully connect the camera and drive the motors.
After some time the trouble began: the camera disconnected randomly and finally wasn't connectable at all. A friend of me now told me the (possible) reason for that: Even on this short distance of 40cm the HDMI cable might cause problems as it doesn't have USB specs and therefore a different impedance. I would never had thought of this, but after some research of course it makes sense.
That means: For the development I am currently connecting the camera via an extra USB cable (meeeh), but I am looking for an alternative cable...

Over the summer it became quite silent around me and the project. Now – with a little bit more time – I'd like to recap my last steps. Starting with the casing:
As I noted in my previous casing post, I had problems with the first case and the velcro fastener. It couldn't fasten the computing unit tight enough, was difficult to apply without help and it couldn't fulfill the demands for comfort to be a everyday-worn gadget. Therefore I repeated the process, I did research and in the end I came up with the following solution:
As a basis I used a15$ detachable phone armband. It comes with a solid band with velcro fastener and a click-attachment. I designed the case so that it can receive the plastic connector, as you can see here:
This new design totally fulfilled my expectations and is a good basis for upcoming experiments with blindfolded and blind subjects. Furthermore the size cannot be significantly reduced further as the main part is still the battery which already has minium dimensions for the 10000mAh it stores...
I am currently working hard to provide further plans, details and code in the next days. Stay tuned and thanks for your support!

this will be a short log, as I am a bit busy and as I'm working hard on the preparation for the Hackaday Price Finals 2019 which I have been nominated for. In the final round there are 20 amazing projects – all of them have huuuge potential and some of them are indeed very advanced and technically complex. Therefore I feel very honoured to be nominated with a more interaction-, design- and concept-focused project.
Last but not least I wrote an application for a research assignment together with my university. If this will work, I could dive deeper into the research and hopefully speed up the process..
These are the reasons why I am currently producing video footage for the documentation like this interview here ;-)
There is still a lot to do, but there will be news very soon. Thanks for your support!

Short update on my progress:
To make everything smaller and more mobile, I designed a new case with a ultra slim 10000mah powerbank from TNTOR. As I didn't need the USB and Ethernet sockets I slimed down my Raspi as you can see on the pictures. The new casing is now already quite neat and slim but the elastic band with velcro fastening didn't work out as expected. It is a little bit too limp and has too less adjustability to different arm. I might have to come up with a different solution here.
