Started some research on slack in the channel #subdermal-wire. There is a lot of information there already, mostly manuals from Medtronic's series of deep-brain stimulation devices. They use silver core mp35n wire and medical silicone or fluoropolymer under polyurethane in various places. The connectors are stainless steal…

This is very cool, I also saw the clip with the full length on Tim's facebook and Im wondering what the flexibility is like when moving the arm? Weird feelings, stretching, tearing etc?

I put a bandage around my ring finger, which made it so annoying to use that I just didn't. I didn't work a job involving a variety of manual movements but it should be fine. I would plan a couple days off (4 sounds good) just to get used to it in case.

Hey @Cassox, is there some info on that transdermal muscle stimulation project somewhere? I am aware of your USB thing but don't think I saw that. @Jupiter power wires for a small electronics project can be very small, I don't really think that would be much of an issue. They should be able run on the inside of various…

I'd definetely throw in like 30-50 euros. I'm native german so I could help out if something like translations are ever needed dealing with the companies here.

Another guess would be that the MRI's field is cycled at such a high frequency (in the tens of MHz if I got that correctly from light googling) that the oscillation cannot be felt, but I'm not sure if you could still pick that up with your nerves.

About the subdermal plate thing: I've seen lots of comments here on magnet sizes etc stating that larger, flat things embedded under skin sound like a good idea for a while, but actually don't work because you completely isolate the tissue on top and blood circulation etc. will not properly function. Of course the physical…

it works for me if I switch the editor into plain-text mode (last icon on the lower toolbar) before entering the text field (otherwise i can't type a single character). this is caused by the editor javascript, i assume it's presenting a fake textarea or input and removing it when it gets focus, which makes my keyboard…

There were lots of new chipsets in the lasz few years for IoT projects that often feature integrsted BLE or WiFi. For example I know the ESP8266: https://de.m.wikipedia.org/wiki/ESP8266 You can see how tiny it is on the development boards alfeady. There are other microcontrollers that are smaller than this but don't have…
-
I would suggest unless absolutely needed not to add any other microcontrollers to what is already present in the base circuitry. A Qi-kit should probably work without, and a battery indicated should be buildable with basic passive components. If you want to replace the circuitry, there's lots of integrated solutions that…

Just google 'Android RAT', there is a couple.There's simpler payloads (just googled and there's 'android/meterpreter/reverse_tcp' for example) but if you don't know meterpreter then a RAT (Remote Administration Tool) is probably what you want.
-
Pretty sure I would pay 300+ too.I have been thinking about this sort of thing for a while too, but I don't really have the qualifications to actually design something (though I am getting there ever so slowly). For me, BLE connectivity, some sort of well designed power supply and a few readable LEDs would be all that is…

added my info and made the first line sticky so it's easier to fill in information

https://www.youtube.com/watch?v=ktzL6yKCfN0 made a little video showing some things - not sure whether I can embed it here?

On my lenovo ideapad the lid sensor is above the keyboard, I was actively looking for it with a stronger fridge magnet when I found it; now I can trigger it with my finger too but I have to hit the right spot pretty closely to make the display go black.I wrote a little something to execute custom actions when I trigger the…
-
There probably is a way to get something running on windows, but I don't know the architecture there and it could very well be that the software would need to be a driver to access the information there. I am using evdev, which as I just found out is completely linux specific, meaning mac os isn't possible either. I will…

Well, other people were talking about how multiple magnets can kind of give you a "Stereo sense" (3d). Also there can't be just one nerve line per Hand, if there is then how can I feel with each finger?
-
@ThomasEgi well obviously running just the electrode is more energy efficient, but I'm saying LEDs don't eat too much power to last a day (which would be fine with me). Anyway, instead of arguing about the output for a few more pages (it's not like we are going to change opinions, I want a smartwatch, you want a…
-
If you read my last post again, you will find that I talk about exactly those notifications :P so yes, entirely possible and planned. And also yes, the shocks are given via electrodes, he's talking about the same thing. I think we could/should just have LEDs and electrical stimulation. Also @ThomasEgi I doubt that Morse…
-
@ThomasEgi The bluetooth part is pretty easy. About LEDs and Electrodes: we can certainly have both. most LEDs drain 20mA in one color if lit at full current and full PWM signal time.If you have the clock on for 5s and light minute, second and hour each in one elementary color at full PWM cycle then that would be…
-
@ansamech that depends mostly on the battery, but the rest is much smaller than the circadia, and that is also what I am going for. I won't even think about implanting this as long as it looks as monstrous as the Circadia does, this project has some aesthetic value.
-
That idea has been discussed in other threads a lot IIRC and is probably going to work to some extent. There is a watch with this principle out called "Durr" but I don't know how good it actually works. Multiple electrodes in a ring (or any other formation) might be a little hard to tell apart, but I'd like to hear @glims…
-
@ThomasEgi We're talking Bluetooth Low Energy here, it has 3 sleepmodes between 270 uA and 0.5 uA (1uA is the lowest you can go to wake up with internal clock). Also, like I said above, the LED current can be minimized by using the gyroscopes in a relatively simple manner. I am currently looking into the MPU-6050 Gyroscope…
-
According to my current plan there will be 12 RGB (Multi-color) LEDs in a circle that work more or less like your everyday-analog watch but that can also show other things (blink in different colors for notifications, rotate colors to just look fancy etc.) For showing the time every LED would represent 5 minutes, an hour…

(Continued because text is too long) Components I have found or am searching so far:* BLE112 or BLE113 bluetooth module for OTA updates * optionally a second microcontroller (ATMegaXXX) [BLE113 above if not] * PCF8563 RTC (Real-Time Clock), Date- and Timekeeper + Alarm and Timer (might be reduced to just a RTC w/ input…

This is completely ridiculous, there are a lot of different reasons, but alone the magnet force <-> weight ratio is far worse than 1:1: If you want to stick to the wall you need to have a friction force (a lot) bigger than your weight. If you were to climb with your bare hands on a sticky steel surface, you could get a…
-
In theory it would be possible (the BLE113 is supposed to run off a coin cell battery alone) but as soon as you add anything interesting to the circuit (LED, vibration motor) you are going to drain waaaay too much power (even if you manage to find a usable energy source in the first place)
-
So, after a few days of research I believe I have found the closest-to-perfect bluetooth module for this sort of use. The BlueGiga BLE113 (Datasheet) basically has most everything you could wish for. It's ~16x10x2mm, which is notably larger than the other modules above, but is still a very small size (and actually easier…

Well, I meant flexible enough to withstand for example the slight curvature of the arm and allow for some shock absorption instead of breaking a thin PCB. And for casing, if you basically dip your design into slightly flexible silicone, wouldn't that work?
