Microview necklace

In my last couple of microview blogs I posed the idea of making a removable circuit – meaning something to put a microview into which you can then take it out without requiring desoldering, and more importantly, without cutting off the microview pins.

I posed this question to twitter, and here were some suggestions:

The current winner is the final one by Grahame, mostly because I already had a dip socket with 14 inputs I wasn’t using.

I snapped this in half and cut off the unnecessary pins, and bent back the ones I did need:

I then got my soldering iron and stripper (whitwoo), cut off the ends of my heart rate sensor: I measured these so that it makes a circuit necklace similar to the necklace I made for york Raspberry Jam by placing the Microview in the center of my chest and pulling the wires to where they needed to be.

I then soldered these on, Data and ground to one header, power to the other and tried my necklace on again:

I look so impressed…

After some fiddling and getting it off my neck again I put some sugru I had from EMF camp on the headers to make it smoother and more finished, and some on the sensor itself to make the connection stronger:

Next steps after this are to put in a battery: I currently have one LiPo with me from my metawear kit I could repurpose: not sure where the best place to put this in is, possibly round the back of my neck again.

I also want to make the positioning of the microview more stable.

Ooh and for those who didn’t check my twitter: I’ve also released the code for this project on github.
