Brad shares a project from the depths of COVID lockdown: a budget DIY mechanical keyboard. As a student, Brad yearned for a fancy mech, but a lack of funds resulted in a far more impressive route: soldering a Teensy directly to the switches of a completely DIY typing tool. The [...]| PJRC
The pocket-sized instrument allows anyone to create pleasant-sounding chord progressions, without requiring extensive knowledge of music theory. Strumming the “harp touch zone” allows any of twelve notes to be triggered and, with continued contact, held. The Teensy 4.0-based instrument can also act as a MIDI device over USB. Having won Seeed’s Co-Create competition, the minichord is now available for purchase. The hardware and firmware to build your own is available on GitHub, and excel...| www.pjrc.com
We’ve all dreamed of flight, but Nick Rehm’s dRehmFlight VTOL brings that dream closer for hobbyists and hackers looking to get their weird contraptions airborne. Based on a Teensy 4.0 plus TDK MPU-6050 six-axis IMU, the project is intended to teach flight control and stabilization concepts, rather than competing with [...]| PJRC
Yang Zhang, Wolf Kienzle, Yanjun Ma, Shiu S. Ng, Hrvoje Benko, and Chris Harrison have created ActiTouch: robust touch detection for on-skin AR/VR interfaces. Instead of traditional handheld controllers, the system uses the body as an input device. A smartwatch-style wristband contains a Kinetis K20 microcontroller running firmware prototyped with [...]| PJRC
Combining some spare keyboard switches and a 3d-printed case and caps with Teensy’s built-in Human Interface Device (HID) mode, the gag gift gives off a surprisingly professional vibe, not to mention a fair number of laughs. Despite being intended as a joke, the keyboard could be useful for video editing, or … using Stack Overflow!| www.pjrc.com
Aaron Todd is the eponymous hacker behind the One Hacker Band — a social media sensation that uses electronics to make musical instruments play themselves via MIDI. Guitars, percussion, a Novation keyboard, vocals — OHB’s got it all, and it’s all powered by Teensy! Aaron takes us behind the scenes [...]| PJRC
The motion capture solution is based on five Teensy LC boards with TDK MPU-6050 six-axis gyro/accelerometer sensors for motion, with the four “limb” units also adding AMS AS5047 magnetic rotary position sensors for joint position. A central Teensy 4.1 connected to each of them orchestrates data collection. Dynamixel servo actuators power the arm using an Arduino MKR-style shield connected to the 4.1. After training the system using all of his real limbs, James then swapped in the 3d-print...| www.pjrc.com
The C-Thru Music AXiS-49 plug n play music interface was a velocity sensitive MIDI input device designed for composing and arranging music. Ben Glover’s Midihex is a new MIDI controller inspired by the AXiS-49, with 98 playing keys and an additional five function keys. What the original [...]| PJRC
In a world of increasingly app-controlled devices (I need three different apps just to turn my lights off at night, for example!), what was once a convenience soon becomes overbearing. The Deus EM Machina system augments a regular smartphone with a large copper antenna and a custom PCB, which amplifies electromagnetic (EM) emissions from electronic devices, allowing a custom background service on the phone to identify them and launch the appropriate app. In their study, they demonstrated iden...| www.pjrc.com
Dylan Brophy aka Nuclaer Tech has created a Teensy 4.1 carrier board called the Teensy 4.1 Computer, which equips the microcontroller with SBC-like ports and form factor. | www.pjrc.com
We are excited to announce the expansion of our partnership with SparkFun Electronics to include the manufacturing of all Teensy products. Teensy 4.0, Teensy 4.1 and related accessories will now be manufactured by SparkFun in Colorado, USA.| www.pjrc.com
