2014-10-25 (Sa) tDCS Unit

An Instructable was started. The simple formate of the pdf instruction manual should simplify the Instructable creation. The pdf was opened for reference and all the full resolution color corrected images were copied to a directory and renumbered to match the manual. Some images were swapped in the manual so an update was made but the link from the blog will always point to the updated version.

The ost expensive part on the tools list is the Helping Hands so a design was conceptualized to build a suitable replacement from inexpensive parts. This will become a new project.


To do:
  • Use a test subject to assemble unit
  • Revise manual
  • Create Instructable

2014-10-23 (Th) Left Index Finger m31 Biohacker Magnet Implant COMPLETED

Guess who passed out again. That's right. As you may have guessed by the title I had another magnet implanted into my left hand to further explore the magnet fields in my world. Some people have reported a better sensation of field shape when more than a single magnet is implanted. It makes sense (pun intended). Imagine trying to feel a bowling ball with a single finger. You can rub it over the surface and figure out roughly how big it is but if you put all your fingers on it at once you can instantly realize its size and shape. Maybe 14 magnets would allow a person to sense magnet fields the way we feel an apple but the law of diminishing returns would probably make it a very impractical list of procedures. Among other problems.

This magnet is significantly thinner than the silicone coated magnet and I requested that it be placed nearly vertical on the middle finger side of the index finger. Here it should avoid any jarring which may occur from being directly under the finger pad.

Now, on to the part where I pass out.

To prepare for this I ate plenty of food beforehand and for 30 minutes right before the procedure I chowed down on sugary foods. When I actually sat down for the procedure I was handed two glucose tablets and I ate them both. I should have been a rock, a slightly jittery rock.

My body jumped the gun this time and before the scalpel did any real cutting I had passed out in the chair and the artist caught me. I woke after having a quick fever dream I can't remember and I was covered in sweat. Keep in mind, nothing had actually happened yet.

Within a couple minutes my wits were fully restored and I indicated I was ready for the rest of the procedure. I felt just fine and this time I actually held a conversation while the artist did his work. While he was stitching me I felt my consciousness pulling back and my vision darkening. I said something and the artist sat next to me but I came back on my own.

The first time I had this done I fell over like a sack of potatoes on stilts and busted my face. When I got an NFC implant by the same artist I passed out after it was injected but I was sitting and there was no issue. This time I was seated again and I knew enough to mention I was getting light headed. The trend seems to be that I pass out earlier and we are better prepared. This may make me the only squeamish, catholic grinder.

A trip to the St Cloud parlor of Wingnut Tattoo & Body Piercing to meet with Shane who performed the procedure on 2014-04-13 (Su) into the left ring finger. The first magnet was a silicone coated magnet designed by Steve Haworth. The magnet used in this procedure was sold by Dangerous Things and features a titanium nitride coating.

2014-10-22 (W) tDCS Unit

Pictures were imported to the docx file but the file size quickly became too large and the computer began to slow down to the point of become useless. The file was broken into pieces to manage the size. To create a single useable document the images should be scaled before insertion into the document. This will also help when the document needs editing.

The Mouser parts were photographed as well as an image of the clamps over the edge of the table which is used several times in the manual. An animated image of all the pages was made for demonstration. It was made from the segmented pdf files.

2014-10-21 (Tu) tDCS Unit

Parts arrived from Mouser so everything was ready to assemble the first unit according to the instructions written previously. The instructions were followed and photos were taken, 84 total. Some steps were revised during the process. A list of steps to add and eliminate was made. Two steps should be eliminated and fours reps should be added from and to the manual. The photos were rotated and automatically adjusted for color. An animated image was created. The time stamps from the photos indicated it took two hours from the first photo to the last.

To do:
  • Add and eliminate steps
  • Take photo of Mouser parts
  • Replace placeholder images
  • Use test subject to assemble unit
  • Revise manual
  • Host workshop

2014-10-20 (M) tDCS Unit

The manual steps were numbered 1-66.

Some research was done into HDtDCS where the primary difference seems to be electrodes encircle a central electrode placed over the area of interest on the scalp. This is supposed to reduce the negative effects of treatment such as reduced ability in other brain functions due to proximity to the cathode electrode. More searching was done to make a custom shape electrode which completely encircles a small electrode. A material was found which is absorbent and does not require stitching at the edges. It was a car shammy made from a gamy material. Its absorbency makes it a top candidate for electrode material. The shammy became rigid when dry but is pliable when wet.

Car shammy held out to show rigidity

To do:

  • Take photos
  • Crop and touch up photos
  • Replace placeholder images
  • Use test subject to assemble unit
  • Revise manual
  • Host workshop

2014-10-18 (Sa) IoTHackDay

Today is a double post! On Saturday I attended IoTHackDay (Internet of Things Hack Day on FB). Most teams there consisted of two kinds of people, programmers and programmers who knew how to operate a bandsaw. Our team was a designer, an entrepreneur, a mechanically inclined person (also the tallest person in the room), the collaborator, and myself. In a sea of nerds we were the oddballs.

3/5 of the team

Our goal was to build a VR headset in 12 hours. A smart phone, my smartphone, was the core. The hard part was making a device which could hold the phone the correct distance from the user and lenses AND be small enough to fit in a pocket. Since my phone was one of the components the pictures are all courtesy of other team members. Thank you. I had a little experience making VR equipment because of the LEGO Virtual Reality Visor. While that is hardly high tech a stereoscopic viewer doesn't have to be.

We went through several iterations and ideas about how to finish this device ranging from a tapered sleeve idea based on collapsible drinking cups, to arrays of hinges, and an idea based on book binding techniques. In the end we arrived at a solution so simple we couldn't ignore it and used sheer nylon stretched over a frame and then the phone was pressed back into it to hold it snugly while giving it shape. Without the previous iterations we never could have arrived at the final design.

We got an experience unlike any other by the sheer diversity of our teammates. Our presentation was also among the most professional sounding and led by the entrepreneur who has an MBA.

2014-10-19 (Su) tDCS Unit

Sketches were made of each module and included 1/8" (3.5mm) sockets for connecting the battery enclosure unit via a male-male 3.5mm cord and the 3.5mm electrode wires.

The first unit was a simple monetary switch which cuts power when the user released the switch. This ensures the user will not forget the turn off the unit but was designed so the user can fall asleep without leaving the unit active. It may be possible to reviser she electrodes and "quiet the brain" so the user can sleep even he or she has a lot on his or her mind.

Switch module sketch

The milliammeter module allows the user to monitor amperage levels during use and could possibly help with placement and knowing when electrodes are conducting well. This module would work well in conjunction with the adjustable current module.

Milliammeter module sketch

The adjustable current module allows the user to lower the amperage from the 2mA of the stock unit down to 0.4mA. The 20K Ohm potentiometer would be accessible from the outside of the enclosure and have markings to show where each amperage setting is according to rotation. This module would work well in conjunction with the milliammeter module

Adjustable current module sketch

The timer module used an externally powered timer to shut off the unit after a preprogrammed amount of time. This is similar in purpose to the switch module but also allows the user to concentrate on other tasks without having to worry about when to shut off the tDCS power.

These devices can be used individually or attached in series with a 3.5mm male-male cord. They can be constructed from metal enclosures which provide another path for the phone sleeve conductor.
