This new add-on board for the Raspberry Pi gives you an HDMI Input

The Raspberry Pi is one of those micro-computer development boards that I often wonder how we ever lived without, and in recent months, the add-on board market for the Raspberry Pi has exploded with several high-quality boards that do everything from add Add Arduino Support, to increasing Audio capabilities.

Today I stumbled across a new add-on board for the Raspberry Pi that adds in HDMI input functionality that has the ability to let users stream HD video footage straight from their camcorder to the Pi and on to the Internet with very little effort. This new add-on board allows users to connect any HDMI video source and sent it straight to the Raspberry Pi. This could come in handy for those who use the Raspberry Pi as a media center and would allow Blu-ray playback or allow streaming directly to the internet.

Meet the MicroView, a chip-sized Arduino with built-in OLED display

Anyone who follows my articles here at TweakTown knows that I am a sucker for new Arduino-compatible development kits, and I especially like the micro-sized boards that are easily hidden inside projects. As such, a new Kickstarter campaign has caught my eyer and I just had to share it with everyone.

 

TweakTown image news/3/6/36440_1_meet_the_microview_a_chip_sized_arduino_with_built_in_oled_display.jpg

 

The MicroView is a "Chip-Sized" arduino-compatible that features a built-in OLED display, and is sized perfectly for bread boarding, or use in many different projects. Unlike many of the Arduino-compatibles that pop up on KickStarter every month, MicroView includes a purpose designed course that walks users through building 11 different circuits, making the MicroView an ideal development kit to use in a classroom environment.

 

 

A pledge of just $45 gets you a single Micro-View with OLED Display, while $55 lands you the MicroView plus USB Programmer. $95 lands you the MicroView, USB Programmer, Learning Kit, and a Cross-Platform Interactive Course. For educators, a pledge of $1350 will land you 15 of the Learning Kits and Teaching Materials. At just $55 for the MicroView and Programmer, I think I just might add one of these to my ever expanding collection of development boards.

This plasma arc speaker is way cooler than your expensive Hi-Fi setup

At some point, I am sure that most of us have fantasized about being the stereotypical mad scientist who spends his days in a lab filled with chemical experiments and electricity arcing from one source to the other. While most of us will never make it to this point in our scientific endeavors, we can have a cool device that sends arcs of electricity shooting from one electrode to another, and have it play music at the same time.

 

TweakTown image news/3/6/36306_1_this_plasma_arc_speaker_is_way_cooler_than_your_expensive_hi_fi_setup.jpg

 

A new Kickstarter campaign from ExcelPhysics is offering kits that let backers build their own speakers that emanate sound by using nothing but the plasma generated when electricity arcs from one electrode to another. "A plasma speaker plays music just like your normal speaker but it uses an arc of electrical plasma running at 30,000 volts," the company said on its Kickstarter page. "Most people aren't aware that plasma arcs can be modulated to generate sounds so your friends will be in for a surprise when you explain to them that the plasma arc IS the speaker! Your typical speaker uses an electromagnet to vibrate small drums, but a plasma speaker uses an electrical arc to ionize and compress the air around it to play music, all with no moving parts!"

Check out this dual Arduino Micro XPlorerBoard on Kickstarter

Electronic education kits were one of the highlights of my youth, and I spent many hours attaching resistors, wires and other components together via those little shiny springs. Today with microcontroller boards such as the Arduino being as cheap as they are, educational electronic kits have taken on a whole new look, and ease of use. The Portable Dual Arduino Micro XPlorerBoard is one of those new easy to use educational electronic boards.

 

TweakTown image news/3/6/36302_3_check_out_this_dual_arduino_micro_xplorerboard_on_kickstarter.jpg

 

Featuring support for two Arduino Micro boards, the XPlorerBoard makes life easy by eliminating loose parts, and adding in very handy features such as a 3V and 5V logic level converter, on-board power supply, and a full compliment of analog and digital sensors. Since the XPlorerBoard was designed for education, the entire board is coated in an anti-static coating and all of the leads on the bottom are protected as well.

 

The entire board along with accessories fits neatly into a standard binder as well, making the board portable and easy to carry to class or your favorite MakerSpace. The XPlorerBoard is being offered through a KickStarter campaign right now and appears to be one of the best value educational development kits on the market at the moment. Best of all, the XPlorerBoard is a product of Savanna, Georgia, and not too far from my home town!

Pi-Bot is an educational robot platform built around the Arduino

Educational robotics hold a special place in my heart, and over the last few years, I have designed several different models that I have used to teach both my self as well as others the theory behind embedded electronics for robots. All of my designs have been based on the Arduino development platform though, something many educational robotic kits default to. A new project on Kickstarter aims to continue trend and focuses its build around Arduino to offer an affordable educational robot.

 

TweakTown image news/3/6/36299_1_pi_bot_is_an_educational_robot_platform_built_around_the_arduino.png

 

The Pi-Bot has been engineered from the ground up, with several full redesigns throughout the process to make things more affordable, functional, and educational. It's makers have included students in the design process as well to ensure that the project is appealing and fun. The Pi-Bot gets its name from its Pi symbol shaped chassis, and not from the utilization of a Raspberry Pi like the name would have you believe. The educational kit is being offered through Kickstarter and is well on its way to reaching its funding goal now. Check out the source link below for more information.

Element14 now offers 7 and 4-inch LCD screens for Beagle Bone boards

A few months back I reviewed what I consider to be one of the best development boards on the market today, the Beagle Bone Black. In that time I have grown to realize the true potential that is locked inside the Beagle Bone Black, and unlike the Raspberry Pi (another favorite of mine), the Beagle Bone Black has much more I/O to share even when connected to a massive LCD touch-screen.

 

TweakTown image news/3/6/36298_1_element14_now_offers_7_and_4_inch_lcd_screens_for_beagle_bone_boards.png

 

Recently, Element14 unveiled one of the coolest "Capes" for the Beagle Bone series to date. Dubbed the Beagle Bone View, these new add-on LCD screens come in 4.3-inch and 7-inch sizes and feature a 4-wire resistive touch panel. The 4.3-inch model features an effective resolution of 480x272 pixels while the 7-inch version has a slightly higher resolution of 800x480 pixels. The boards are powered directly from the Beagle Bone Black or Beagle Bone with no external power connection needed to the screens.

Lulzbot unveils new Flexystruder for printing with Ninja Flex

For the better part of the past decade 3D printing has mainly been relegated to printing objects in hard solid plastics such as PLA, ABS, and Nylon, but recently, great progress has been made in the advancement of flexible, more rubber-like filaments. One of the major hurdles has been the development of a reliable extruder that can feed the flexable filament into the hotend.

 

TweakTown image news/3/6/36239_1_lulzbot_unveils_new_flexystruder_for_printing_with_ninja_flex.jpg

 

Today Lulzbot released its new Flexystruder Tool Head designed for use with its TAZ 3 3D Printer. Lulzbot says that the FlexyStruder was specifically designed for use with NinjaFlex flexible 3D Printing filament, and that setting up the new tool head is fast and easy. From what I can tell, the Flexystruder is based off of Lulzbot's Budaschnozzle design and is mounted on a carrage designed to fit into the TAZ 3's Z quick-change extriuder carrier.

Element 14 launches Raspberry Pi sound card

If you are the DIY sort that is always tinkering with One project or another, you may be familiar with the Raspberry Pi. This cheap little developer board has found its way into many a cool project since it launched. One thing that the device has been missing is its own sound card.

 

TweakTown image news/3/6/36208_12_element_14_launches_raspberry_pi_sound_card.jpg

 

Element 14 has announced the launch of a sound card for the Pi to fill that gap in features. A Wolfson audio processor is integrated into the sound card and supports audio at 24-bit/192KHz. It can be directly connected to an amp using a 3.5mm output or a digital S/PDIF output.

 

The sound card also handles audio recording using a pair of onboard MEMS microphones. One of the nicer features of this card is the price. The Wolfson Audio card for Raspberry Pi sells for $33. Affordability is one of the hallmarks of the Pi and its accessories.

Awesome dad creates electric batpod replica for his kids

If you gauge a childhood on how many awesome things your dad built you, mine was horrible. My dad was unable to sit still long enough to help with Legos before he had to go watch football. This dad is definitely doing it right when it comes to awesome creations.

 

TweakTown image news/3/6/36196_43221_awesome_dad_creates_electric_batpod_replica_for_his_kids.jpg

 

The dude built his ten and 12 year old boys a small replica Batpod. It doesn't look much like the one from the flick, but it is awesome nonetheless. We will have to look around the fact that the kid appears to be riding it in shorts and Crocs; at least he has a helmet.

 

The bike was a custom build and is powered by four car batteries that use lead-acid. Those batteries hook to a Mars ME0709 electric motor and the powertrain uses an Alltrax AXE 4844 controller. None of that will mean much to most of us.

This morning Afinia announced the launch of its next-generation 3D Printer that features several innovative new features included automatic bed leveling and nozzle height detection. The new Afinia H480 is the successor to the popular H479 which was the company's firs desktop 3D printer and quickly grew in popularity with makers everywhere.

 

TweakTown image news/3/6/36160_1_afinia_launches_its_new_h480_desktop_3d_printer.jpg

 

The new Afinia H480 features a printing envelope of 5-inches cubed, a build envelope of 5-inches cubed, and features a heated build platform. The entire printer has a footprint of just 9.6-inches by 10.2-inches by 13.7 inches, allowing it to fit on any desktop surface. The inclusion of Automatic Leveling takes the H480 a step above the competition as it removes one of the tedious setup task that can consume valuable time. Automatic leveling works via a detachable Platform Calibration Probe which measures the build platform at nine different locations to ensure a perfectly level printing surface.
