As many of the followers of my blog know, the Teensy 3.1 and Teensy LC have been my favorite microcontroller boards for the past couple of years.  The Teensy 3.1 has since been replaced by the slightly better Teensy 3.2, which has a better voltage regulator but is otherwise pretty much the same as the 3.1.  I’ve been using the Teensy LC with PteroDAQ software for my electronics course.

I’ve just noticed that PJRC has a Kickstarter campaign for a new set of boards the Teensy 3.5 and 3.6.  These will be much more powerful ARM processors (120MHz and 180MHz Cortex M4 processors with floating-point units, so at least 2.5 times faster than the Teensy 3.2, more if floating-point is used much).  The form factor is similar to before, but the boards are longer, taking up 24 rows of a breadboard, instead of just 14.  The extra board space is mainly to provide more I/O, but there is also a MicroSD card slot.

The designer is still dedicated to making the Teensy boards run in the Arduino environment, and the breadboard-friendly layout is very good for experimenting.

PJRC is positioning the new boards between the old Teensy boards and the Linux-based boards like the Raspberry Pi boards. The new Teensy boards will have a lot of raw power, but not an operating system, though I suspect that people outside PJRC will try porting one of the small real-time operating systems to the board.

The new boards are a bit pricey compared to the Teensy LC ($23–28 instead of under $12 for the Teensy LC), but still reasonable for what they provide.  PJRC also has a history of providing good software for their boards.

I probably need to get both a Teensy 3.5 and a 3.6 to port PteroDAQ to them—that looks like a $50 purchase. If the boards and the software are available in time for me do development on PteroDAQ by December, I might get it done—any later than that and I’ll have no time, as I have a very heavy teaching and service load for Winter quarter.

I suspect that the new Teensyduino software will need a newer version of the Arduino development environment, which in turn would require a newer version of the Mac operating system (my laptop is still running 10.6.8), which in turn probably means a new laptop.

I’m waiting to see if Apple releases a new, usable MacBook Pro in October, so there is a bit of built-in delay in the whole process. I’m not impressed with their recent design choices for iPhones and MacBook Air—I need connections to my laptop—so there is a strong possibility that I may be having to leave the Macintosh family of products after having been a loyal user since 1984 (that’s 32 years now).

Breaking bad habits can be difficult, but developing better ones isn’t so easy either. Mindful of this, former Project Ara founder Dan Makoski and David Khavari have come up with a smart, Arduino-friendly lamp that combines light, encouraging messages and a personal improvement algorithm to help you inch closer to your goal day by day.

Connect Peak to your smartphone using its configuration app and set up a habit you’d like to master–whether that’s exercising, reading more, learning a new instrument, meditating, or spending quality time with loved ones. Simply touch the lamp and it will then send you a motivational text message. It recommends a step towards your target that you’ve either entered yourself or have chosen at Peak’s suggestion. You can schedule reminders if you need that extra little push as well. Once completed, touch it again or text Peak and it’ll record your progress, celebrating with a burst of light.

What’s even cooler is the fact that Makoski and Khavari were fortunate enough to work with whiz kids (and our friends) Cesare Cacitti and Quin Etnyre. Peak was actually prototyped using the Arduino platform and currently runs on Etnyre’s own Qduino Mini. Its creators are also exploring the idea of opening the lamp up so developers and Makers can hack their own projects. We’ll have to wait and see until the end of its crowdfunding campaign!

Looking to form a better habit? Enjoy mini light shows? Then head over to Peak’s Kickstarter page, where you can learn more about the product, the philosophy and the entire design process.

As its name would suggest, the LittleArm is a mini 3D-printed robot that began as a weekend project. Its creator Gabe Bentz wanted a small arm that was easy to work with, and one that wouldn’t require him to dig deep into his wallet. So, as any Maker would do, he decided to design his own low-cost device.

After showing the LittleArm off, it wasn’t before long that he was approached by some STEM teachers in the area who wondered if the kit was something they could use in their classrooms. Ideally, every student should have one to tinker with, but unfortunately today’s systems tend to be too expensive and quickly loose parts and pieces. This is a problem that LittleArm is looking to solve.

The arm is powered by an Arduino Uno and four identical metal-geared micro servos, while all other mechanical components are 3D-printed. There’s also a modular gripper that’s actuated by a servo along with rigid end-effectors for various tasks. What’s more, a basic GUI enables you to control the arm, its gripper, the speed, as well as use its record function to train the robot to perform a specific task and then watch it play out the sequence.

The entirely open-source gadget comes as a DIY kit that can be purchased or built from scratch. Want one of your own? Check out Bent’z Kickstarter page here, and see the LittleArm in action below (including some of its dance moves).

Hi everyone! 

My name is Gregory, but you can call me Greg. I am a 17 year-old high school student who is building a very interesting robot(I am also doing all of the designing and prototyping. I am building a six-legged robot, called a "hexapod", that is able to teach itself to walk.

Who can resist video games when they’re packed up in tiny, tiny little arcade machines? [Ken]’s hoping that you cannot, because he’s making a cute, miniature Arduino-based arcade game platform on Kickstarter. (Obligatory Kickstarter promo video below the break.)

The arcades are based on [Ken]’s TinyCircuits Arduino platform — a surprisingly broad range of Arduino modules that click together using small snap connectors in place of pin headers. The system is cool enough in its own right, and it appears to be entirely open source. Housing these bits in a cute arcade box and providing working game code to go along with it invites hacking.

There’s something about tiny video cabinets. We’ve seen people cram a Game Boy Advance into a tiny arcade cabinet and re-house commercial video game keyfobs into arcade boxes. Of course, there’s the Rasbperry Pi. From [Sprite_TM]’s cute little MAME cabinet to this exquisite build with commercially 3D-printed parts, it’s a tremendously appealing project.

But now, if you’re too lazy to build your own from scratch, and you’ve got $60 burning a hole in your pocket, you can get your own tiny arcade — and tiny Arduino kit — for mere money. A lot of people have already gone that route as they passed the $25k funding goal early yesterday. Congrats [Ken]!

The name of the game in rocketry or ballooning is weight. The amount of mass that can be removed from one of these high-altitude devices directly impacts how high and how far it can go. Even NASA, which estimates about $10,000 per pound for low-earth orbit, has huge incentives to make lightweight components. And, while the Santa Barbara Hackerspace won’t be getting quite that much altitude, their APRS-enabled balloon/rocket tracker certainly helps cut down on weight.

Tracksoar is a 2″ x .75″ x .5″ board which weighs in at 45 grams with a pair of AA batteries and boasts an ATmega 328P microcontroller with plenty of processing power for its array of on-board sensors. Not to mention everything else you would need like digital I/O, a GPS module, and, of course, the APRS radio which allows it to send data over amateur radio frequencies. The key to all of this is that the APRS module is integrated with the board itself, which saves weight over the conventional method of having a separate APRS module in addition to the microcontroller and sensors.

As far as we can see, this is one of the smallest APRS modules we’ve ever seen. It could certainly be useful for anyone trying to save weight in any high-altitude project. There are a few other APRS projects out there as well but remember: an amateur radio license will almost certainly be required to use any of these.

Today Punch Through Design launched a Kickstarter campaign for their new Bluetooth LE Arduino-compatible microcontroller board the Bean+.

Everybody needs an external USB drive at some time or another. If you’re looking for something with the nerd cred you so desperately need, build a 5 1/4″ half height external drive. That’s a mod to an old Quantum Bigfoot drive, and also serves as a pretty good teardown video for this piece of old tech.

The Woxun KG-UV2D and KG-UV3D are pretty good radios, but a lot of amateur radio operators have found these little handheld radios eventually wear out. The faulty part is always a 24C64 Flash chip, and [Shane] is here to show you the repair.

Last year there was a hackathon to build a breast pump that doesn’t suck in both the literal and figurative sense. The winner of the hackathon created a compression-based pump that is completely different from the traditional suction-based mechanism. Now they’re ready for clinical trials, and that means money. A lot of money. For that, they’re turning to Kickstarter.

What you really need is head mounted controls for Battlefield 4. According to [outgoingbot] it’s a hacked Dualshock 4 controller taped to a bike helmet. The helmet-mounted controller has a few leads going to another Dualshock 4 controller with analog sticks. This video starts off by showing the setup.

[Jan] built a modeling MIDI synth around a tiny 8-pin ARM microcontroller.  Despite the low part count, it sounds pretty good. Now he’s turned his attention to the Arduino. This is a much harder programming problem, but it’s still possible to build a good synth with no DAC or PWM.

Digistump has recently announced a partnership with Particle over cloud infrastructure that may well be a signal that the diasporan expansion in microcontroller market may be coming to an end.

After two and a half years of work and dozens of prototypes, Kaia Dekker and Jesse Vincent have launched Keyboardio Model 01 on Kickstarter: an heirloom-grade mechanical keyboard designed for serious typists.

As you’ll see from the video presentation below, the Model 01 is not just a keyboard. Kaia and Jesse actually re-envisioned the way we type to make it feel great. On top of that it has a beautiful hardwood enclosure and it ships with source code and a screwdriver. The Model 01’s firmware is a regular Arduino sketch you can explore and change yourself.

The project reached its target in the first few hours and you have a few more days to get one!

In the meantime they also joined the Arduino at Heart Program to make it fully customizable with the Arduino IDE:

We’ve built the Model 01 around the same ATmega32U4 microcontroller that Arduino uses in the Arduino Leonardo. Early on, we figured we’d eventually switch away to a cheaper ARM microcontroller, but then we fell in love with just how easy Arduino makes it for a new programmer to get up to speed. For all intents and purposes, the Model 01’s brain is a regular Arduino. You can update your keyboard from the Arduino IDE. If you want to make your keyboard do something special, there are thousands of Arduino resources online to help you out.
