New tiny parts

In the never ending quest to find a Voltage level shifter, to drive addressable LEDs, I found myself looking at these http://www.ti.com/lit/ds/symlink/sn74lvc2t45.pdf . These ICs can do 3.3V to 5V translation for 2 pins at a whooping 420Mbit and they cost $80c (USD) . So I ordered 5 from TI….

Yep… that’s damn small. Not sure how I’m going to use those… I have no Surface Mount skills or equipment..Should have read the damn data sheet properly. Anyway, I’m glad there are 5, I will try my damn best to solder those pins to some larger pins and if i break any ill have a few extra to play with. If they work, ill be able to eliminate the Driver Pixel that i use in most of my application, most importantly ill be able to properly test higher data rates for the APA102 and the SK9822 pixel.

Next on the list are these $4 single cell Power Banks:

These use a single 18650 to produce 5V at a maximum of 1A… With one more nice feature. They don’t have a power button. They activate simply when a load is detected. I’m using this as a test bed, and in a very non recommended way, I’m sure. I have the Output ports of all 4 into 1 Female USB port and was successfully able to power one of my latest creations:

 

Lots of hexagons

I have been hard at work on this new piece, for which i have not yet come up with a name..

It is constructed with 20 Hexagonal pieces. Each laser cut out of clear perspex. Behind each is a grid of APA102 LEDs all controlled by an ESP8266

MOFO 2016 – Electric Light Yoga & Faux Mo

This year, I was chosen to work with a talented costume designer Sabrina Evans, to create 10 LED covered suits for MOFO 2016 the summer arts festival held by MONA in Hobart Tasmania. The results were amazing

One of the suits was used in an awesome arty yoga session, also held at MONA, called Electric Light Yoga. Above is one the shots. Here is the suit from behind…

Noodles of cabling! The rest of the suits were used by actors at the Faux Mo nightclub event on Saturday. They roamed around the huge art filled space, created by Jamin Kluss for MOFO. The make shift nightclub was built inside 12 Murray Street, Hobart. The ex government building is to be demolished shortly and was well utilized.

But nothing is without complications. The box containing the battery modules for all the suits was shipped down to Hobart using Fastaway couriers(don’t use them). They advised a 3 day shipping schedule, its been 6 days and the box hasn’t arrived yet. I had to repurchase all the battery modules in Hobart at an exorbitant price

Here they are charging the night before the main event, at our Airbnb that we rented in Battery Point, Hobart(no pun intended).

A new project for MOFO 2016

I have been commissioned to create 10 LED suits for Faux Mo as part of MOFO the Summer Arts festival in Hobart, Tasmania. The webbing of the suits was built by Sabrina Evans, an awesome costume designer form Hobart. The webbing is made of nylon and clips on to the person.

Not yet sure what will be done with all 10 suits, but here are a few demo shots of them in action on my model:

Some mad disco patterns

A few other samples:

Each suit is powered by a 20,000mAh 5V Battery module. The Strips are APA102 and controlled by a NodeMCU/ESP8266 Micro Controller.
