OSH Park ~ Welcome

OSH Park ~ Welcome
OSH Park is a community printed circuit board (PCB) order. We bring you high quality, lead free boards (ENIG finish), manufactured in the USA, and shipped for free to anywhere in the world. 2 layer boards are $5 per square inch (with 3 copies of your board included in that price) and ship in under 12 calendar days from ordering. 4 layer boards are $10 per square inch (also including 3 copies of your board), go to the fab once a week, and have a 2 week turn time from the fab. We can also support larger runs. See the pricing page for a full list of offerings. This service grew out of the DorkbotPDX PCB Order and later grew to include BatchPCB.

Chipper - The ATtiny Programming and Prototyping Shield by Ben Rothschild The Chipper Shield allows anyone with an Arduino or AVR programmer to easily program ATtiny chips. ATtiny chips are the core behind many projects that only need a few pins and cost a fraction of an Arduino ($1-4). With access to PWM and Analog pins ATtiny chips can take on any project in 8, 14 and 20 pin form factors. You've Never Seen a Robot Drive System Like This Before What you're looking here is a hemispherical omnidirectional gimbaled wheel, or HOG wheel. It's nothing more than a black rubber hemisphere that rotates like a spinning top, with servos that can tilt it left and right and forwards and backwards. Powered by this simple drive system, the robot that it's attached to can scoot around the floor in ways that I would have to characterize as "alarmingly fast." Before I go on about the design, have a look at just what this thing is capable of. Its creator, Curtis Boirum, a grad student at Bradley University, in Peoria, Ill., demoed it at the 2011 RoboGames symposium:

Hacking a laundry machine in one day (SLE4442) - Limpkin's blog Before starting this article, I first have to say that I won't publish all the information required to perform this manipulation, due to the obvious legal aspects of it. However, I will explain in details the security of this particular laundry machine, without showing any picture that would help you know which one it is: Let's start. First step, understand what we are up against. Supercapacitor Digital Calipers I got some supercapacitors from Katie, and my first project was to replace the battery in my digital calipers with a capacitor. Digital calipers are great, exept for when the batteries are dead. Who has those tiny watch batteries laying around anyways? Digits Digits is a wrist-worn sensor that recovers the full 3D pose of the user's hand. This enables a variety of freehand interactions on the move. The system targets mobile settings, and is specifically designed to be low-power and easily reproducible using only off-the-shelf hardware. The electronics are self-contained on the user's wrist, but optically image the entirety of the user's hand.

E-Ink Display for Any Microprocessor by ePS Project Team The new video is of our hardware controlling the E-Ink Display Module. We chose a 5 frame image; a Sierpinski Triangle. This is calculated and displayed at less than 5 frames in 3 seconds entirely on our ePS prototype board. Control is by a command interpreter running on the ePS Display. These prototypes help us make the final design decisions for the three production boards, one for each size display. Our prototype boards were assembled on the pick and place machine which was featured in our first movie.

PCB CNC aus Metalab, dem offenen Zentrum für meta-disziplinäre Magier und technisch-kreative Enthusiasten. Introduction CNCs can facilitate in the creation of PCBS: Manual etching and then using CNC to drill automatically. Cutting out the board , to have round PCBs, or similar. Automated isolation routing: From a PCB some surface parts are milled away, so that the connection copper area are left isolated.

projects HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone's headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation. HiJack has been tested with the iPhone 3G/3GS/4G, iPod Touch, and iPad devices. Cloud Shield, Twine's Gateway To The Full-Blown Internet Of Things If you’re not afraid of hacking together a bit of code and plugging tiny wires into a credit-card-sized circuit board, you probably already know what an Arduino is. If not, here’s the short version: An Arduino is a little electronic brain you can program to do interesting interactive stuff, like dim the lights in your living room when you turn on your TV. It lets you turn dumb objects (or environments) into smart ones. Meanwhile, you may have also heard of Twine, a little green box full of sensors that lets you connect physical objects to the Internet without having to know any code at all. If you’ve ever wanted your basement to send you a text message if it floods, Twine is for you.

uArm, A Mini Robotic Arm You Can Assemble and Control Robotic arms live in factories, tirelessly assembling heavy things, cutting through metal (like butter)—and generally doing some pretty dangerous and crucial work. But unless you run an industrial firm, chances are you haven’t had the chance to own one. Until now, that is. Part 1: Mac OS + Eclipse + OpenOCD + STM32 (ARM Cortex M3) Intro I really wanted to program and debug ARM processors from my Mac. This series of entries is a work in progress as I fine tune my setup for regular use. Be sure to read the full story: Part 1: Getting Started, what we are going to do and what parts we are going to use.Part 2: Laying the Foundation, getting all the parts installed.Part 3: Connecting the Plumbing, hook up all the pieces and run it.Part 4: Finishing Touches, troubleshooting and final thoughts.
