Quoc Le's Lectures on Deep Learning
Gaurav Trivedi has put together a landing page with all of Quoc Le’s recent lecture series and accompanying resources:
Dr. Quoc Le from the Google Brain project team (yes, the one that made headlines for creating a cat recognizer) presented a series of lectures at the Machine Learning Summer School (MLSS ’14) in Pittsburgh this week. This is my favorite lecture series from the event till now and I was glad to be able to attend them... (cont'd with all videos)
Effect of Robotic Driverless Vehicles on Auto Insurance Costs
The effects of RDVs is requiring the insurance industry to change its business dynamics whereby a greater portion of the liability will be moved from the car owner to the car manufacturer and infrastructure providers (federal and state).
Upcoming Tradeshow, Conference & Exhibition Summary - August, September & October
The end of Summer and beginning of Fall brings alot of great tradeshows for the Robotics and Advanced Manufacturing industry. The Chicago area is the place to be with several great shows scheduled. Here is a look at some of the key events for the next few months.
Parallella: $119 Parallel Computing Platform with 16-core Epiphany chip
Parallella Computer Specifications:
The Parallella platform is an open source, energy efficient, high performance, credit-card sized computer based on the Epiphany multicore chips developed by Adapteva. This affordable platform is designed for developing and implementing high performance, parallel processing applications developed to take advantage of the on-board Epiphany chip. The Epiphany 16 or 64 core chips consists of a scalable array of simple RISC processors programmable in C/C++ connected together with a fast on chip network within a single shared memory architecture...

Raspberry Pi Model B+
From Eben Upton, Raspberry Pi Founder:
This isn’t a “Raspberry Pi 2″, but rather the final evolution of the original Raspberry Pi. Today, I’m very pleased to be able to announce the immediate availability, at $35 – it’s still the same price, of what we’re calling the Raspberry Pi Model B+.
The Model B+ uses the same BCM2835 application processor as the Model B. It runs the same software, and still has 512MB RAM; but James and the team have made the following key improvements:
More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.
More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.
Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
Better audio. The audio circuit incorporates a dedicated low-noise power supply.
Neater form factor. We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes... (cont'd)
Where will the 3D Printing Industry Cluster?
Innovation networks tend to cluster around specific regions because all the necessary ingredients of finance, people, infrastructure & regulation tend to converge in one area by accident & design.
Intro to Shape Memory Alloy Actuation Using Flexinol
From Jie Qi's projects page:
Shape memory alloys (SMAs) are metals that change shape when heated up. They are wonderful actuators in that they are light, silent and can be "turned on" by simply running current through. The shape that they change to can also be set, though this process is a bit more tricky. Flexinol is a particular brand of nitinol, which is an SMA made of nickel and titanium, and is pre-set to contract about 10% of its original length when heated.
In my projects, I generally used the 0.006" to 0.01" diameter, High-Temp wires.
Since Flexinol draws a lot of current (about 300mA for the diameters I used), you need a strong power supply like a wall supply or a good lithium-ion battery. I've used from 3.7V up to 6V (any more and my Flexinol wires would start overheating). To turn the Flexinol on, I would simply short the ends of the wire to the power. For digital control, I used a standard MOSFET circuit which is a digital switch that can be turned on and off using a microcontroller... (cont'd)

Interview with e-NABLE Founder Jon Schull
By far, one of the most inspirational and impressive projects thats come from the 3D printing/DIY community has been the work were seeing on open-source assistive devices, and one online organization that is playing a major role in making this happen is e-NABLE, a group started by Dr. Jon Schull of Rochester Institute of Technology.
BugJuggler: Project to build 70ft tall robot that juggles cars
Project Overview:
BugJuggler will use a diesel engine to generate hydraulic pressure. An operator located in the robot’s head will be able to control its motions using a haptic feedback interface connected to high-speed servo valves. Hydraulic accumulators - essentially storage batteries for hydraulic fluid - will allow for the rapid movement required for the robot to juggle cars or other large, heavy objects.
The first stage of the BugJuggler project will be construction of a working 8ft tall single arm proof-of-principle juggler able to toss and catch a 250lb mass... (cont'd)
