Vivid 2018 LED IoT Apparel !

Hello! 

Continuing with the tradition of creating something beautiful and covered in LED lights, this year we have something special!

Previously, we had the LED Jacket with Tearschu, and the LED Dress with Naifel. Taking inspiration from these, and solving a lot of the problems I faced with them, I bring the latest iteration of light up fun.

This year, I have taken a pair of high heel boots, and an umbrella from Daiso, added plenty of pretty lights, and of course, this year marks the first year the entire project is connected to the internet.

 

 

The project was built using mostly the same core components for each item. 

The shoes each have:

  • Lithium Ion Battery (1000mAh)
  • LiIon Charge / Boost circuit MP2636 
  • WeMos D1 Mini
  • A random switch for power
  • A strip of WS2812 LEDs

The umbrella is similar, except instead of the MP2636 boost circuit and 3.7v Lithium battery, I used a 3s LiPo battery, and a 5v step down regulator capable of high current.

 

The physical build was pretty straight forward, hook up everything how you please, battery to boost/charge, from there to the WeMos / LEDs, and then route the wires how you please. For LED placement on the shoes, I went with up along the front as I feel this will look the best having the light cover the most area, and for the umbrella I ran the lights down the spokes of the umbrella.

Unfortunately with my design you cant really CLOSE the umbrella anymore but as this is just for Vivid I am not too fussed 🙂 

To attach the LEDs to the umbrella I initially tried to use hot glue, but it was actually melting through the umbrella, and the parts that didn’t, did not hold very well, so I ended up using clear packing tape, as it does not seem to get in the way of anything and is barely noticeable! 

The LEDs here are hooked up in parallel with each other, so each spoke on the umbrella will be the same.

Once it is all made up physically, we can move on to the code.

I was looking into using the McLighting project for control of these, as it has both an internal web interface as well as support for things like MQTT, but I could not get it to work reliably, and it didn’t support running in AP mode, only client mode, which was a big turn off for me.

So what I ended up using was the JSON LED code from BRUH Automation, because I use this for other things at home and it works pretty reliably.

One thing to note here, for my LEDs I had to add the following two lines of code, BEFORE including the libraries, to prevent flickering of the strip. (not sure why this works?)

#define FASTLED_INTERRUPT_RETRY_COUNT 0
#define FASTLED_ALLOW_INTERRUPTS 0

 

(at the verryy top of the sketch)

 

Now my initial plan included taking a small portable router, and a Raspberry Pi 3 out with me to vivid, running a local MQTT server on a local network, with the Pi running Home Assistant (Hass.IO) all locally so I could connect to it to control things. However I ran into many problems attempting to do this, I am not sure if its because I don’t know how to properly setup static IP’s in resin, or just because it hates me, but I kept not being able to connect or it wouldn’t respond to my commands, it just wasn’t working great.

 

One day though, my good friend Mark came over and we needed a project to work on, so what we set up was a private mosquitto MQTT broker, that requires authentication, running in Docker on a Ubuntu Server 18.04 LTS install!

What this meant,  was I now had a secure way of connecting a remote node to my Home Assistant running back home.

 

I went right ahead and adjusted the code on the three items for the new server, forwarded the ports in my router, added the config to my production Home Assistant server, and hey presto, was I glad to see, everything JUST WORKED.

 

I made a view in Home Assistant and threw all the entities into it, and here’s how that looks:

So as you can see, we can control both shoes together, each individually, the umbrella on its own, or everything as a group!

We also can change the animation speed of the various effects.

I will be heading out to vivid to shoot a small video and some photos with this, with my good friend Tsugumi modelling it for me, on the 9th of June 2018 from about 6PM onward, Not sure if I will be at Circular Quay or Darling Harbor yet, keep your eye on my Instagram to find out! 😉

RGB LED Jacket ft. Tearschu

Last year, Tearschu and I worked together to bring the LED Dress to life, and that was a huge success!

 

This year, I worked with Tearschu to create another RGB item of clothing!

 

Tearschu designed and made a jacket with a clear PVC material, and we incorporated a strip of 144 WS2812b RGB LEDs into it, this was a challenge, as the power draw was too much for the 3-5A 5v power regulator we used last year.

 

We needed a much beefier 50W power supply! However thanks to some help from Reddit user /u/krhacken we were finally able to get brightness control working mere days before the shoot!

 

This allowed us to dim the lights for scenes where they were too bright, and for when we were just walking around between locations to conserve power!

 

We were able to go the entire 3-4 hour shoot with a single Turnigy NanoTech 1.6Ah 3S LiPo!

 

Im really happy with how the photos turned out and I can’t wait to make something for next year!

 

Make sure you ‘like’ the photos on Facebook!

LED Dress was a success!

Hey all!

Just a quick update to let you know the LED Dress was an awesome success!
It looked better than I imagined!

Once again I want to express a huge thanks to Tearschu for making the dress perfectly, and Naifel for modelling it so beautifully! (Thanks Tim for helping too!)
It’s an amazing feeling having an idea and making it become a reality!

Heres some sneak peeks before I get around to editing the photos:

LED Skirt mark 1

I decided that this year for Vivid Sydney, I will do something I have wanted to do for a long time.

I am going to create an LED skirt.

I got the inspiration from SexyCyborg with her LED skirts over here:

My DIY Underlit LED (Hikaru) Skirt

I’m going a slightly different approach though.

Rather than just skirt-underlighting I am commissioning Tearschu to make a frilly skirt similar to this dress here

Edit: found some similar to the look im going for!
http://www.instructables.com/id/LED-Skirt/

Dress I made for my Senior Prom, hope you guys like it!

I am going to be embedding some strips of WS2812B addressable LEDs into the skirt, hopefully it’s going to give a nice washed colour effect into the whole skirt!

I will post progress pictures as I go with the build.

Parts list:

LEDs: http://www.ebay.com.au/itm/162068083230
Arduino Nano: http://www.ebay.com.au/itm/182093493024
Power UBEC: http://www.ebay.com.au/itm/271700451532
B
attery: Turnigy NanoTech 3s LiPo

 

Power source:

I am going to use a hobby UBEC that can do 5v at 3-5 amps 🙂
I have linked it above under the parts list. It will be connected to a 3s LiPo battery for powering both the arduino and the LED strip.

The LED strip can draw up to 3.5 amps at 5v at full brightness, this will only really happen if all the LEDs are lit, and white. but to be safe I am investigating power sources that can handle this.

I may end up just using a USB battery bank with its 2.1 amp output.
I am pretty sure thats all ill need.

Nevertheless I have a reddit post in /r/askelectronics over here where I am asking if there’s a better solution!

Some other projects that I may find useful to refer to:

Prototyping!

I rigged up a little 3 pixel test strip to get the code worked out, ideally I want to have a push switch that can change between colour patterns / modes.

I’m looking around to see if this has been done before because I’m terrible at code \o/

I did some testing with a 16 pixel ring to get a better idea of the colour mixing.
I really love the colours that come out of these things, they’re so vivid and will mixed!
I’m getting super excited for this to happen!

Update:

The electronics are ready!
I have completed it all and the power supply works and i’ve charged up the batteries!
Check out these pictures:

Update: 
The code is ready!
I have uploaded it to GitHub here: https://github.com/CountParadox/NeoDress/
It’s made from a number of places and things mashed together, it has a few modes, and is fully configurable of course.
Tactile switch on digital pin 2, leds on pin 6, set for 60 leds at the moment.
has an off state, a rainbow chase, and a number of solid colours because they’re nice!

And here’s a video of the strip!

TBS Discovery Pro Restoration

Hello!

So this post is going to be basis for a number of updates, essentially I picked up a TBS Discovery Pro quadcopter off ebay for $200 in pretty crummy condition, and im in the process of restoring it to its former glory.

This post is where I will be posting my progress on this, as well as to reddit but eh, this is my turf.

So just for backlog:

Here’s the eBay item page:

http://www.ebay.com.au/itm/231843059723

Here’s two threads on me trying to identify damaged / broken off components:

So I am restoring this quadcopter….

Can I just take a moment to vouch for how incredible isopropyl is at cleaning these boards? just look at the photos and see for yourself.

Here’s the auction win screenshot:

Finally, here is the album of the photos of my initial disassembly / the damage.

View post on imgur.com

The hardest thing for me is going to be replacing the I2C port on the Pixhawk…

I really don’t know if I can do it, and im worried I’ll mess it up even more..

 

If you’re great at tiny soldering please hit me up if you can help!

The SD card, I WAS able to pull flight logs and data from it, but I won’t post it here because it probably reveals the location of the previous owner’s home..

From the electronics I have tested, it appears to work, and the telemetry is a 433Mhz 3DR system. (I confirmed later by removing the heat shrink.

The gimbal motors need replacing, and the main motors need new bearings, the I2c port needs replacing, and the receiver needs its antenna to be fixed or replaced. The top board MIGHT not work, I cant test until the gimbal is repaired. but that would be around $220 to replace im told.

Once these are done, I am confident it will fly once more! (oh and two props are fecked)

Ill also need a new telemetry module, as having one isn’t very helpful 😉

The USB port on the Pixhawk was pretty crusty and unreliable, but ordered this and connected it up and we’re back in business!

As I mentioned at the start, Ill update here when I have more to post!

Updated Photograhy Site

Hello!

I have finally fixed this blog so that its back!

I have also finally updated the slideshow and description on my photography site: http://paradox.photography/

 

I was having a heap of issues with the DNS, but my good friend Tyler Adler from http://adlerhost.com/ is helping me out with DNS and web hosting.

 

Now, a challenge I faced with the slideshow was that I wanted to showcase some of my portrait oriented photos, but the slideshow only allowed for landscape orientation. I didn’t want to let this stop me though to I chose my favorite three photos in portrait and fit them together in photoshop, over the top of one of the landscape photos.

I was experimenting with some other photos too, but I think these worked best.

 

I will have to change the dimensions of the image though as its cropping it on the actual page.

Yay for photos! \o/
