Website Redesign!

  Posted July 19th, 2010 | No Comments »

Well well… look who has finally decided to move his blog design out of the dark ages!  I’ve spent the last month or two working on this new blog design – I really hope you like it!  It takes advantage of a whole bunch of new wordpress blogging features like nested comments, better tag support, and widgets.  For all you newcomers, here’s a shot of what jeremyblum.com used to look like:

RIP Previous Blog Layout (2007-2010)

Compare that…to this!

The Shiny New Website Design!

If you have any comments on the new design, please feel free to let me know what you think!

Let’s get Digital…or Analog!?

  Posted June 20th, 2010 | No Comments »

Pardon the stupid title for this post.  It’s simply what popped into my head.  Anyways…I’ve got a new episode of techbits!  It’s been several months since the last episode, but hopefully my recent electronics projects have kept you entertained in the meanwhile.  This time, I’m talking about analog and digital signals – Both of which are inescapable in computers and all other electronic devices.  Enjoy!

SudoGlove – Hardware Control Using Hand Gestures

  Posted May 9th, 2010 | 2 Comments »

Complete System

Update 5/19/10 – I have uploaded the final report, code, schematics, laser-cutting files, and sound effects!  Read on to download them.

Introducing the SudoGlove Control System!  This is my final project for INFO4320 at Cornell Engineering.  It was developed by me and three other students: Joe Ballerini, Tiffany Ng, and Alex Garcia.  You get geek points if you can figure out why we decided to call it the SudoGlove.  Here’s a hint

SudoGlove aims to bridge the gap between the user and traditional physical hardware devices. Given the high learning curve in understanding how to use foreign technologies, we hope to break away from conventional control mechanisms and explore an intuitive way to control these devices. SudoGlove provides a tangible interface that relies on hand gestures to wirelessly control any device or software. By removing the distance between the user and traditional hardware devices, our goal is for SudoGlove to feel more like an extension of the body as opposed to an external machine.

As an investigation into this idea, the goal of this project is to capture simple hand gestures from the SudoGlove and use that input to wirelessly control a modified RC car. Controlled variables include speed, steering, forward/reverse, headlights, siren lights, siren sounds, and a horn using a combination of flex, force, vibration, and gyroscopic sensors.

News: SudoGlove has been featured on Hack-a-Day!

Read on for a demonstration video, photo gallery, additional information, and downloadable content!

3D-Printed Glowing Puzzle

  Posted May 4th, 2010 | No Comments »

3D Puzzle Design

Ahh yes, the joys of college – awesome people, parties, concerts, quadrangles (they are important!), problem sets, final exams, and of course, awesome prototyping equipment.  Take for example the objet 3D-Printer.  We use one in Cornell’s Computational Synthesis Lab (CCSL), where I am employed as an undergraduate researcher.  But the information sciences department also has a 3-D Printer in their Human-Computer Interface (HCI) Lab.  The Prototyping and Physical Computing Class I’m enrolled in this semester tasked us with designing a 3D puzzle to be printed on one of these machines, so that’s what you’ll see in the video after the break (and the CAD picture above).  This is my third and final design project for this class.  Check out my first two here, and here, and stay tuned for my group’s final project! You can view all my mini projects for this class on my secondary youtube channel.  The source code, schematics, and STL/CAD designs are available after the break as well!

Arduino-Powered Jack-in-the-Box Toy

  Posted April 3rd, 2010 | 3 Comments »

Remember the last design project I posted?  Well this second one is for the same Physical Computing class, but is totally different.  This time, the assignment was to create a Jack-in-the-Box toy.   To make mine unique I added password protection and an alarm system to the box.  Check out the video below to see what I’m talking about.  As always, I’m making the source code and schematics available below via a creative commons license, so grab it after the break!

I have also made some other mini projects for this class. I’m posting videos of all assignments for this class on a separate youtube channel here: http://www.youtube.com/jeremyeblum.

Update: Hack-A-Day Featured this project on their blog!
