GrindDC Meatup: Thursday Bio-hacking

  • May 9, 2013 · 7:00 PM

An informal meeting of people interested in bio-hacking, diy-bio,
implantable technologies or other form of 'meat hacking'.

 

Highlights this week:
  • 6:30p; A visit from a representative from Trimech. Trimech is a local company that resells SolidWorks and provides Education and Consulting services. We reached out to them for no-cost/low-cost educational licensing for Solidworks. The rep wants to have a look around and see what we're up to and how they might be able to help.
  • 7:30p; Nathanial, from Imagnus Biomedical is coming by for a visit to discuss collaboration on a medical device. He's interested in working with us to develop a product.

    I will bring my EEG server thingie and will conduct an experiment on chewing grapes and looking at the EEG. I've observed some serious microphone effect, and am looking for test subjects to replicate the experiment

    Exciting stuff Shawn!

    So things I've been working on:

    1. Data visualization. A side project of mine has been learning the javascript D3 library, and potentially as a project for the Neurosky hackathon I'm going to try and make some cool graphs out of the eeg data. If anyone has good suggestions for biosignals to visualize, let me know.

    2. Northpaw system: Not much progress to report, a little work done on it over the weekend. I've got proof of concept working using an led to light up when compass is at particular position, now we just need to hook up motors.

    On my todo list for tonight:

    1. Finish soldering tcds.

    2. Get some prelim plan in place for microcontroller interface for tcds.

    3. Finish pomodoro app (unrelated to biohacking, but still, got to get it done)

      Ooh, I've read the Pomodoro Technique e-book. What sort of app is it, Android (fingers crossed)?

      Nice! Yah its kind of a task list + pomodoro mashup. I really want to incorporate a todo list feature so I can 'bill' pomodoro cycles to a tag and then look at stats over time/my estimates. Haven't been able to find a good existing one, so figured I'd take a crack at it. I'm using phonegap to make it available to multiple platforms/web, so android's on there!

    Things I've been working on this week: 1. A digital compass implant/toy: https://github.com/nocko/northstar . It has a three axis accelerometer and magnetometer, a microcontroller and an LED. The idea is that you could gesture/shake it to wake it up (programmable pin interrupt from magnetometer or accelerometer) and it'd light up when it was pointed north. The primary goal of the project is a sub-$5 development board for the accelero/magnetometer and to learn avr-libc to break my dependence on the Arduino platform. The software needs heavy work. I am currently implementing TWI/I2C via the ATtiny45's USI . Then I'll work on a library for interacting with the sensor.

    2. Rev. B of the HELEDD (Pittsburgh implant) is complete (https://code.google.com/p/heledd/source/browse/#svn%2Ftags%2Frev-b%2Fhardware). The PCBs arrive today or tomorrow. Sharad and I will likely schedule a build in the next week or so. This version has the hall-effect sensor, and improved charging circuit/power supply.

      Oh, and the Rev. B board ought to be programmable via Bluetooth.
