Missed the GM4s? Us too. It took much longer than we expected to get them through clearances this time, but they've finally made it to our doorsteps!
I created this choker as a project to demonstrate the new MicroNova APA102-2020 LED strips.

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!
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.

Alrighty, the week has already slid by and it's time for another update. We have one new product to show off - Practical Arduino by Jonathan Oxer and Hugh Blemings. It contains 13 projects packed into 16 chapters/420+ pages, covering a wide array of an Arduino's potential. It's a pretty comprehensive read. Perhaps the biggest […]
After we have survived recent natural disasters like floods and thunderstorms, mosquitoes are another disaster that needs elimination. I don’t like mosquitoes. They are evil vampires lurking in the dark. Flies on the other hand are jovial and rich in protein. Cats usually specialize in them. But cats don’t tackle mosquitoes very well.. . I […]
This may come as a bit of a shock to you, but the hands that package your orders actually belong to humans. Sure, we may be a robot company, but robo-hands just aren't quite up to spec for what we need to do. So for the moment we're staffed by a contingent of mortals, and […]
