A couple of new pieces

First off we have the lovely pink lady from many a Coco Poco Loco party:

wpid-20150915_114513.jpg This is in fact a very silly looking fiber glass model of a naked lady. It has a base with a normal bulb inside.

The outside is covered in small glass pieces and the inside is covered in jagged fiber glass that cut my arm up pretty badly

I was asked to work my magic and here it is:

I put a strip in the head, onto the bust, all the way up the spine and along the lower parts of the front facing legs. The whole thing uses about 68 LEDs from a WS2812b strip. I used a NodeMCU for this, just for shits and giggles and to see if i could get it to drive WS2812B strips. I used THIS modified NeoPixel driver with the NodeMCU module running at 160Mhz. Note you must use the UART driven library on Pin 4. Here is another example:

Next up is Jords Disco Shoulder Pads

I used a Arduino Nano for this along side a WS2812B LED Strip. The results is hillarious:

My best piece to date in my opinion:

NodeMCU – A super cheap and lightweight IOT device

Dear Intel, Thank you for wasting my time with your rubbish IOT devices. I can surely say that i wont touch the Galileo’s or the Edison again..or at least until they fix the software that cripples the Edison.

In comes the Node MCU which is a dev board for the ESP8266 Wifi Module.

For $15 AUD you get a 180Mhz device that has SPI, a ton of memory and built in and WIFI that boots and connects in under 5 seconds. Not only that, you can upload Arduino code just the same as any Arduino on board  which makes porting existing projects super easy!

I have been playing around with these with thanks to my new friend Rob. I was quickly and easiely able to port my LED software onto these and make it net connected..

 

The Orbitron

The main part of the Orb is complete. I have gently sealed in all the glass prisms and stretched Cotton/Lycra over the top part of the sphere:

I was able to crunch the code down to the Nano module. I’m left with just over 400 Bytes free. Here are 2 short demo patterns:

 

I still need to cut out a section of the sphere to store the Arduino Nano and then cut out a mounting hole for a staff.

Production Update – LED Orb

I Still don’t have a good name for this piece, however it is coming along nicely. I was able to get all the inside LEDs into the sphere and wire everything up:
