Help Hackaday Buy Our Own 3D Printer UPDATED!

beggars

UPDATE: We’re getting a LulzBot thanks to [Jeff Moe].

ALL DONATIONS ARE BEING REFUNDED. YOU WILL STILL RECEIVE YOUR STICKERS.

We’ve held out for far too long. Hackaday now needs a 3D printer.   We get emails all the time asking why we don’t have a donate button. Well, we’re kind of stubborn and would rather just do with what we have. Unfortunately this hasn’t gotten us very far in the 3d printer department.

We have a few projects in mind that could really utilize a 3d printer, namely building custom game controllers for children with special physical needs.

If you have any interest in helping us get a 3D printer for Hackaday, read on. Otherwise, carry on with your day.

Telepresence Upgrade With A Minimum Of Effort

telepresence-upgrade-with-very-simple-parts

This telepresence upgrade lets an employee take part in the office from more than four thousand kilometers away. It’s an upgrade of their previous setup which used a laptop on a rotating platform to add a bit of control to the video conferencing experience. But all that original version could do was swivel, this one lets you drive your virtual self around for fifteen hours between battery charges.

The real work is in the base of the robot, as the audio and video are handled by a tablet independently from the locomotion. The team spent about four hundred bucks to throw the thing together. It starts with a hunk of plywood. Two 3A motors were mated with lawnmower wheels for the front of the bot. Dragging under the back of the base are a couple of casters that make it possible to turn without skidding. A motor shield and a WiFi shield for the Arduino make it possible to control the thing over the Internet. They even added some functionality on the client side to use a PlayStation 3 controller. Check out the completed machine in the clip after the break.

Announcing: Hackaday Videos And Behind The Scenes Mailing List

hadfilm2

We’re starting a few new things at hackaday. As always, our goal is to share awesome hacks from as diverse a crowd as possible. We’ve played with video a bit before, but now we’re really going to start having some fun with it.

Our first exploration into this area was the hacked portal gun. People enjoyed looking at it, and those seeking more in depth technical knowledge came to the site to get it. Instead of focusing the video on the technology or the build itself, we used it as an interesting way to get the attention of people with relevant interests. This video proved to us that our idea was solid.

We have now stepped up our production in terms of quality and quantity.  We will be releasing videos that may be humorous, like a fake commercial or skit, or may be serious in the style of a documentary. They will all have some kind of hack at their core and that hack will be broken down in an article here.

I would also like to extend the opportunity for you to help. There are two ways you can do so:

  1. Sign up for our email list(it is in the right column). I’ll be sharing behind the scenes info and previews about upcoming video projects and asking for ideas on how to improve them.  The list will be very informal, and only deal with behind the scenes kind of stuff it will not be a mailing of the daily posts.
  2. Submit a project or idea that you think would make a cool video. You can email that directly to caleb@. Of course, we would prefer projects that haven’t been released yet, but that isn’t necessary. We’re looking for things that are visually stunning, or could possibly have highly cinematic potential. Not necessarily the most technically difficult thing.

We hope to start releasing videos next week, so keep your eyes peeled. We filmed all week, and my cheeks hurt from laughing so much.

This Has Not Been A Good Week For The Hacker Community

RIP

The Internet lost a few great minds this week. [Aaron Swartz], confronted with an upcoming federal trial for his actions in downloading and releasing public domain academic articles from JSTOR, hanged himself this week. As one of the co-developers for RSS, the Creative Commons license, and slew of other works, [Aaron]’s legacy expanded the freedoms and possibilities of the most important human invention since the book.

Perhaps overshadowed in the news by [Aaron] is [Fabio Varesano], the man behind FreeIMU and Femtoduino. He died of a sudden heart attack at the much too young age of 28. The RC helicopter/plane/drone and HCI/physical computing communities lose a great mind with [Fabio]’s passing.

There is talk on the Dangerous Prototypes forum of continuing the development of FreeIMU, a project it seems [Fabio] worked on alone. We’d love to see someone pick up the reigns of the FreeIMU project, hopefully after doing a run of the current hardware and donating the proceeds to [Fabio]’s family.

Bluetooth Network Monitor

Bluetooth Network Monitor

[Zak] wanted to keep tabs on his network connection without needing to log into his router. Since his router was a PC running Debian Linux, he rigged up a Bluetooth Network Monitor to display the information.

The monitor is based on a ATMega328P that reads data from a Bluetooth serial connection and displays it on the TFT screen. It uses a low cost Bluetooth module to receive data from a router. A shell script fetches the data and formats it into a string that can be sent over the Bluetooth link.

A USB connection with a desktop computer is used to power the device, but [Zak] also added USB support using V-USB. He plans to use it to get data from the desktop. For example, he could display CPU load and temperature data.

Overall, this is a nice project for fetching data wirelessly and displaying it on your desk. [Zak] has provided the code and Eagle files with his write up for anyone interested in building their own.

This Day In Hack A Day History: January 1st 2005

TIMEHAX

A new feature that we’re playing with is an occasional look back at this day in Hack a Day history. While we’re still hotly disputing exactly what, when, and how to show, we thought today would be a great day to introduce the idea.

So, in on this day in Hack a Day history we’re reaching back to our very first January 1, which was 2005.  There are some interesting things to consider when reading this post. At this point in time, we were still sort of  a growth off the side of engadget like [Kuato] from the 1990 version of Total Recall.  We were less than a year old and still hadn’t completely developed our style, we didn’t really share much information about the project, and yep, the very first comment is “not a hack”.
