These addressable LEDs are extremely small, less than 1/4 the size of a standard 5050 LED.
This project was built using engineering sample standard MicroNova 99 LED / meter strips . The MicroNova strips we are selling have 198/meter - twice the density!
Reason for a Choker necklace:
Hats have been done, shoes have been done, pendants have been done.
This is something new for a Valentine’s dance costume, so I decided to go with a choker design. I also wanted something that was interactive, something that would add another layer of WOW to just lighting.
I used a Wemos D1 Mini development board along with a boost-converting battery shield for the Wemos D1.
The battery shield was a particularly good choice here because the MicroNova LEDs should be supplied a solid 5VDC. This board boosts the battery voltage to 5V, and then the Wemos D1 Mini bucks it down to 3V3 for it's own operation.
A mini SPDT Slide switch toggles the power from the battery shield to the D1. This allows charging the battery using the battery shield USB connector while not powering the D1.
Epoxy locks the switch and wires in place.
The battery used is a conveniently handy older 450mAh Lithium Polymer. Depending on the lighting mode, this battery can power the necklace for a couple of hours.
I used elastic thread to attach the LED strip and components to the necklace. A heavy duty needle was all that was needed to punch through the (imitation) leather belt. Because the thread was elastic and tied under tension, it held the MicroNova strip well in place.
When the choker powers up, it creates a WiFi Access Point called "HeartBurnChoker1".
Once I connected to this WiFi, I opened a browser and went to 192.168.4.1. The control interface is simple, but effective. The D1 Mini has more than ample power and speed to effectively drive these LEDs. The MicroNova features separate clock & data lines, so even relatively slow I/O (like Raspberry Pi) can still make it work.
As part of our on-going website upgrades/patches, it seems that fixing one thing tends to ...botch... other aspects of the website. Right now, our shopping cart isn't cooperating. Trust us, if there was an aspect of the website we don't want going down, it's our order forms! We're on it right now, but in the […]
Thinking of coming to the Western Canadian Robot Games this year? Although the games don't have any BEAM events this year, we're still planning on being there to meet up with our customers (and enter a few 'bots in competition!). As usual, we're planning at also having our free annual post-event BBQ, so if you'll […]
Solarbotics would like to announce two new distributors, one in Italy, and the other in Mexico (who says robots aren't cool world-wide?): Robot-Italy is now our dealer out of the ancient city of Rome. We hope to visit them there one day! Our other new distributor is Robodacta, out of Mexico City. Another nice, warm, […]
Word from up the pipe at the Los Alamos National Laboratories is that the 10th Annual BEAM workshop is slated to happen May 2-4, 2002 at the Betty Ehart Center in Los Alamos, New Mexico (same place as the 1999 workshop). Thanks to Joe Vigil (of LANL) who spearheaded the initiative after Paul Argo (the […]
