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:
White Night 2016 in Melbourne may not have been as huge as in previous years, but I sure had a blast. I walked around the Melbourne CBD and surrounds for about 7 hours and got my photo taken by A LOT of people! Everyone I ran into seemed to enjoy themselves and really liked the Wow Suit. Here are a few pics from the evening
I had a friend shoot some really good video of the suit, but until I get my hands on it, here is some from my Instagram:
Notice how the Official White Night Instagram account tells me to apply for an art grant next year, even though they sent me a Generic “NO THANKYOU” when I applied for this years event.
Its s nice little device. No bullshit set up. Easy to use Linux…WiFi was a bit difficult but that is because of Linux. Setting up the standard stuff like FTP, Apache etc.. easy! Getting NodeJS to work with MRAA…..oh lord.
//Get the latest version of node from the node web site
tar -xzf node-v0.10.28-linux-arm-pi.tar.gz
//set the mraa path manualy if https fails
sudo npm config set registry http://registry.npmjs.org/
sudo npm install mraa
//wait a long time....
