Here comes the leg


The leg was the most difficult part to disassemble and it was really a tight fit. I thought they glued those two piece together as it was so tight that I actually tried to find screws on the leg. After convincing myself that this part is okay to be trashed or else I will have to glue the entire leg on my light-weight fancy Gunnar Optiks, I used a flat head screw driver to crack it open, suddenly a clip pop out. I was so happy that I didn’t have to break my little toy into pieces. The last clip was incredibly hard, as the clip was in the thickest area that I couldn’t bend the outer shell using my hand, and the wire did not have any protection as my flat head could cut them into pieces anytime. Eventually, I made 3 of my nails bleeding, and I got the leg assembly apart WITHOUT BREAKING THE CABLE (MOM I DID IT!). Only taping and soldering left. Oh wait…battery still on its way. It’s my first time seeing that package from mainland China arrived before package from Hong Kong.


When my demon hands strike my Myvu Solo

My Torx screwdriver set arrived in the mailbox today, it’s time for me to do some deadly surgeries to my Myvu Solo.

Instead of following the “break every plastic part into pieces” procedure as shown in David Renoir‘s photos. I did find a “correct” way of disassembling the Myvu Solo.


The screws circled in yellow were fairly easy to find. However, the genius engineers did not forget to give us some challenge of finding those two little guys circled red. The Myvu engineers designed two little pieces of plastic camouflage caps to prevent those little screws from being scratched by my Trox screwdriver.

At that point, my patient’s vital signs were still normal. But good things can’t just happen one after another, right? When I saw the glue that hold the little TFT screen to the lens, I thought Myvu was a very good company, and they must have used some industry-level strength glue. Therefore, I called my nurse to bring me the swiss knife. And that was a really really really bad decision. I somehow broke my left TFT as well as the left earphone wire. Image

Nothing looks bad from the outside, however, the little TFT won’t do anything but showing pure white back-lit when his brother does his job just fine. Fortunately, The two TFTs are interchangeable, and I detached the other TFT use my soft bare hand, and replaced left eye’s TFT using the right eye’s TFT, and it worked. By the way, when you see your little TFT only displaying pure while back-lit, don’t be panic at first, you will not be able to see anything unless you use that magnifier lens. If you still see pure white back-lit even with the lens attached, you can go ahead and panic like I did.

I might solder the earphone wires back since I have to solder the 2 LED pins to make it works with only one display anyway. But that’s not the thing I will do now, as I have the feeling that I will mess it up if I do it today.

Another step of my wearable computer project – Myvu Solo Plus video glasses


Inspired by Gregor Richards, I also wanted a monoscopic head-mounted display for my wearable computer, unfortunately, the company — Myvu no longer exists, and the fancier 480p Myvu Crystal is unreliable and pricey to get. Fortunately, the 240p Myvu Solo is reasonably cheap and pretty much as easy to modify as the Myvu Crystal according to David Renoir, though a little of soldering is now required.

The brain of my wearable computer project – MK802 II Android mini PC


Here comes the brain of my wearable computer project – MK 802 II mini android dongle.

It packs with Allwinner A10 1.0GHz Cortex-A8 CPU, 500Hz GPU, 1GB of RAM and 4G of on board storage, but still only requires 5V of power from a simple USB source. Smaller size plus better processing power make it much more suitable to work as a portable computer than the often used Raspberry Pi.
