Finger Model?

Now all I need is someone to be my "finger model".... oh wait I know someone!
Finger Power
Dave's Dev Lab • 05/19/2018 at 00:27 • 0 comments

After carefully disassembling the "finger light", I created a mechanical replacement for the LED. The cheap "finger light" used the cathode of the LED as part of the mechanical switch to turn on power to the LED. So a mechanical replacement was required. After soldering it together, I checked to make sure it was working and reassembled the "finger light"....
Soldering a Nail

No not that kind of nail! A fake acrylic finger nail! after taking my bits and pieces home, I experimented with gluing a red LED to back of some of the nails. It work amazingly well and after applying power, the nail was very brightly lit. Now some engineering questions started happening. If someone glues one of these to their finger, they can't exactly take a shower with the battery attached, so i needed to come up with a connector that was small, robust and above all... pretty! what i came up with is the small the connector commonly used on wifi and bluetooth modules called a U.FL connector. It had golden contacts (pretty!), it was small and easy to use....
Getting the Finger
Dave's Dev Lab • 05/19/2018 at 00:13 • 0 comments

On a non-specific Saturday a few months back, I was with my wife grocery shopping at our local Walmart and terrible bored.... and like any good nerd i attempted to entertain myself with fun engineering challenges. One on of the isles there were some interested "rings" hanging on an advertisement pole:
For the wonderful price of $2.99USD, I got three "finger lights". So, here we were walking around Walmart doing our shopping with me thinking about what to do with these "finger lights". As it happened, we passed the cosmetics isle and I spied the fake fingernail kits and they reminded of diffused LEDs and bingo... LED illuminated fake nails!
to be continued!

Hi! Have you done more on this project? Would love to see it continue...

Are you sure? yes | no

i've done a few more experiments with customizing a bracelet with a power source, and tested some ultra high efficiency LEDs, but overall it was more of a "weekend hack". amazingly enough, i think i've gotten more interest this hack than any of my other "serious" projects....

Are you sure? yes | no

Ha you never know what people will like. I want to see the bracelet!

Are you sure? yes | no

i'm super swamped at $DAYJOB this week, i'll see about trying to post a log entry next week!

Are you sure? yes | no

Neat! This will make an interesting entry for the Human Computer Interface that starts in July: https://hackaday.io/prize/details#four

You can certainly enter the Hackaday prize now and then add the project to the HCI Challenge when it begins.

Are you sure? yes | no

hehe, it was more of a saturday afternoon fun hack, so i probably won't do much more with it... thanks though!

Are you sure? yes | no

Well, I think it's great. The UFL connector especially gives it cyberpunk feel. And I there's a lot of potential for Human Computer Interface experimentation here.

Also, you know those color-selecting fingernails in that movie The Fifth Element? This is kind of like that if you have an LED of different colors. I wonder if there's a way to using a super-small microcontroller and power line signalling to get color LED but not need any more wires than you already have?

Are you sure? yes | no

indeed i do recall the fingernails in The Fifth Element. That was one of my early thoughts on the project as well as this scene from Total Recall linked below. I was thinking of adding something like a attiny into the design to do blinkenlights effects as well as RGBW coloring. The real key to this is making it "fashionable". I've been thinking some type of rings that could hold coin cell would be interesting to use and might apply to other projects...
