[Erik] was looking for a sturdy robotics platform and was initially considering the iRobot Create, until he found that he could score a Roomba Discovery series for a fraction of the price. The Discovery includes a battery, which is missing from the iCreate, though it also has all of the standard vacuum bits included as well. He immediately removed all of the vacuum parts once he got his hands … [Read more...]

Using nearly a dozen marshmallow Peeps, he constructed a stage for his "performers" and a seating area for their "clients".

Like other diy Geiger Counter builds we've seen, this project assembles a circuit to interface with a gas-filled tube which serves as the detector. [Anilandro] takes a few paragraphs to discuss how this works; the Geiger … [Read more...]

Shift register is all it takes to make a 3-wire serial LCD

easy-serial-lcd

This hack is a bit older, but one aspect of the setup makes it worth sharing. Shift registers are a common component to include in a project when you need to increase the number of I/O pins available. We've used them to drive LCD screens before, but we never realize you could use a 595 chip to make a 3-wire serial LCD interface. That's because we've always thought of shift registers as having … [Read more...]

The team at [blablabLAB] have been hard at work on their latest project, which they unleashed on the streets of Barcelona in the La Rambla pedestrian mall. Their art installation allows you to pose in the middle of the mall and receive a plastic statue of yourself as a souvenir. Not unlike the "Fabricate Yourself" installation we saw a short time ago, this project also uses the Kinect to create … [Read more...]

Something new is coming to a store near you: electronic price tags. [deadbird] decided to get one and see what makes it tick. First off it just looks like an LCD with some coin batteries and a simple board, but removing the batteries it was found that the text still appeared on the screen meaning its an E-Ink display. Close examination of the chips on board shows that this model has an ATMEL … [Read more...]
