Junior Robotics online exhibit showcases kids' robots

(Phys.org) —As robotics has become an increasingly popular way to get kids and teens involved in the field of engineering, the robotics projects that the kids are doing have become more creative and sophisticated. A new online exhibit hosted by EXPO21XX, called Junior Robotics, has recently launched and begun showcasing the variety of robotics projects happening in the K-12 scene.

Raspberry Pi User Guide competition

Time for a quick compo. I have two copies of the excellent book Raspberry Pi User Guide to give away! It will help you get speedily underway if you are new to the device, with chapters on the Pi as a Home Theatre PC, as a productivity machine, and serving as a Web server.

Now Boston Dynamics' BigDog can lift and toss (w/ video)

(Phys.org) —Boston Dynamics’ DARPA-funded robotic dog has been upgraded with added functions for military support in hauling gear on rough terrain, Its new appendage is called various things—a “kind of head,” a “face-arm,” and a “canine elephant trunk.” Whatever the terminology, BigDog has a new appendage to its torso that resembles a head. Boston Dynamic’s goal of increasing versatility of roles took a page from movements by human athletes.

TE Connectivity introduces a holder for Sharp LED

TE Connectivity ‘s circular Type Z32 LED holder provides a solderless power connection to the LED chip-on-board device, Sharp’s Mini Zenigata. Direct attachment of the LED holder to the heat sink using standard screws secures the LED without damaging or cracking the substrates that could lead to latent field defects, says the supplier.

Swimming-pool ships make waves in modular robotics (w/ Video)

(Phys.org)—University of Pennsylvania engineering Professor Mark Yim and his students in the Department of Mechanical Engineering and Applied Mechanics have been floating their robotic boats at the university pool after-hours as part of a Defense Advanced Research Projects Agency (DARPA) project. They have received funding from DARPA’s Tactically Expandable Maritime Platform.

BeagleBone Cape Design Contest – winners announced

Texas Instruments has announced the winners of the BeagleBone Cape Plug-in Board Design Contest , announced back in November. The three winning submissions are: Replicape for 3D printers; Interacto providing a foundation for building robots and flying drones; and Geiger Cape, which measures radiation counts.

Vibrobelt buzzes cyclist in right direction

Cycle related gadgets are always of interest to Gadget Master, so I was interested to see an article on New Scientist about a “vibrobelt”, described as “sat nav for your waist”. Basically, it’s a belt to help guide cyclists, with actuators indicating the relative direction to take – left, right, and forwards

Current sense circuit collection

Here is a PDF document from Linear Technology, featuring current sense circuits for different applications, including High side, low side, level shifting, high and low voltage, fault sensing, etc: [ via ] Sensing and/or controlling current flow is a fundamental requirement in many electronics systems, and the techniques to do so are as diverse as the applications them-selves. This Application Note compiles solutions to current sensing problems and organizes the solutions by general application type

Home-made solder paste stencil

bonybrown.blogspot.gr writes: SMD solder paste stencils are used to accurately “print” a thin layer of solder paste onto a PCB on which the components are placed before reflow soldering. The “printing” is done in a method similar to screen printing, where the solder paste is squeegeed through a 4 mil thick, stainless steel stencil onto the PCB
