DIY Wearable Pi with Near-Eye Video Glasses
- enkiv2 12y agoAdafruit asked me to do a writeup of my (very similar) project several months ago. I'm glad that someone else did it instead -- this looks far more slick. The design is superior in at least five or six ways to mine: 1) there's going to be absolutely no fogging problem (mine was goggle-mounted, and fogging was a killer) 2) there's no problem attaching to prescription glasses 3) the thing looks like it's water-resistant, if not water-proof; mine has exposed boards, and would be quite difficult to seal 4) it doesn't look like there are any torque points on connectors, whereas my design required some re-soldering specifically to avoid some problems with torque 5) there's space and surface for mounting other hardware (for instance, a camera) Unfortunately: 1) it looks like it'll be tough to replace the battery after the whole thing is assembled (it's a lithium ion soft pack soldered onto the board) 2) I suspect there will be some balance problems: the HMD unit is somewhat heavy, and appears to be mounted on one side of a normal pair of glasses with no band or counterweight. The glasses might skew to the side or put pressure on the bridge of the nose, which limits the amount of time one can use this for. Now that I have access to a 3d printer, I may need to build one of these.
