(mini)How-To: Refill your DTG inks

Posted: June 9th, 2010, 2:15pm MDT by Jakob Griffith

The number one and number two things asked after presentation of our DIYDTG were… “How does it hold up in the wash?” and… “How did you change out the inks?” While we’ve explained the first several times (regular ink washes out, DTG ink gets a little lighter but survives) we can hopefully answer the second [...]
Building a glue stick flashlight

Posted: June 9th, 2010, 12:10pm MDT by Mike Szczys

Building an LED flashlight is simple, right? Take a battery, connect it to an LED by way of a resistor. Alright wise guy, now make one that steps up the voltage for multiple LEDs and don’t use a boost-converter IC to do so. [fede.tft] shares a flashlight built inside of a used glue stick case. [...]
Linux tablet built around a BeagleBoard

Posted: June 9th, 2010, 11:09am MDT by Mike Szczys

[Justin] shows us how to make a Linux tablet out of a BeagleBoard. You may remember [Justin's] work at liquid cooling an Arduino. For this one he moved past the AVR hardware but took the idea of shields along for the ride. The device above is something of a Linux tablet, with a touchscreen shield [...]
Resurrecting ISA hardware

Posted: June 9th, 2010, 10:09am MDT by Mike Szczys

[Alex] had an old FM radio tuner card come his way. It used an ISA connector, a standard that went the way of the dodo in the mid-nineties. With the challenge of implementing an ISA-bus to configure the card he set out on his mission. What he came up with is a working radio using [...]
Preserving old stuff with the Library of Congress

Take a few moments and browse this gallery from the Library of Congress. Tasked with the job of preserving the roughly 150 million historical items, they are constantly developing new methods using bleeding edge technology. There is an odd balance of some of the oldest documents in tandem with some of the newest technology evident [...]
Baxter the ButlerBot and RoboFridge

Posted: June 9th, 2010, 8:00am MDT by Caleb Kraft

[Steve Norris] has been devoting his time, effort, and knowledge to the most noble of causes; cool beverage acquisition. Baxter the ButlerBot and RoboFridge work in tandem to deliver cold ones when needed. As you can see in the video, this possibly over engineered system works quite smooth. Though the details on his site are pretty [...]
Distributed Flight Array

Posted: June 9th, 2010, 7:00am MDT by Caleb Kraft

Though it is in the beginning stages of development, the Distributed Flight Array is already looking very interesting. Each unit can scuttle across the ground using the down force from its prop, but when 4 or more join forces, they can take off and fly. The documentation shows that they should be smart enough to [...]
