This instructable goes through how to design and print a variety of 3D models using a system called the ‘UCube’. Note:  I would love to eventually publish detailed instructions on how to make your own UCube, but since the design is still changing and improving, this post will gloss over a lot of those details […]

Activities of daily living (ADL) are self-care activities that are usually taken for granted, since as the name implies they are performed on a daily basis. If you have ever ended up in a cast, or on crutches you can empathize how menial daily activities can suddenly be very difficult to perform. Waking up in the morning and maintaining a schedule […]

*Check back for more updates on this build 🙂 So, have you heard of the Omnibot? Well! Any kid from the 80’s will remember how amazing this robot was. For you young kids, this robot was released in the early 80’s by Tomy. The robot was “programmable”, in the sense that the actions were recorded […]

How to: Speaking Clock Hello 🙂 Setup and Procedure The wave shield is interfaced with the Arduino Mega 2560 as normal. A couple of pins were remapped because the wave shield was initially made for a different device. The DAC pins were remapped to pins 22,23,24 and 25 on the Arduino board. The WaveHC library also […]

I’m still working on the LED calculator (original idea and most recent work) — I’ve finally got ’round to adding a rotary encoder to set the target system voltage. Now you can turn the potentiometer to set the LED brightness, turn the rotary encoder to set what voltage will be used in the ultimate LED circuit, and […]

Cree has introduced a multi-die 500 lm (80CRI, 3,000K) surface-mount lighting LED, aiming to compete against multiple single-die medium-power LEDs in automated luminaire manufacture. The idea is analogous to the way bolt-down multi-die chip-on-board modules (CoBs) are taking-on single-die LED boards in manual assembly lighting manufacture. Named MH-B, the new LED “combines the reliability and […]

SAN DIEGO – December 09, 2013 – Qualcomm Incorporated (NASDAQ: QCOM) today announced that its wholly-owned subsidiary, Qualcomm Technologies, Inc., has introduced the Qualcomm® Snapdragon™ 410 chipset with integrated 4G LTE World Mode. The delivery of faster connections is important to the growth and adoption of smartphones in emerging regions, and Qualcomm Snapdragon chipsets are […]

I’m researching squeeze sensing as a mode of tactile interface. Here I will cover the process of developing a squeezeable sensor and the firmware/software concerns associated with interpreting the data from the sensor. This fulfills the “sensor project” for my class called Computational Principles in Media Arts taught in AME at ASU by Todd Ingalls […]

Exar has announced a new family of USB to serial bridge devices for industrial applications. The XR21B142x family interfaces with RS-232 or RS-485 serial networks. The XR21B1420, XRB21B1422, and XRB21B1424 provide 1, 2, and 4 UART channels respectively. The XRB21B1421 provides a single channel UART and uses the native operating system HID (Human Interface Device) […]

The latest automotive electronics boom has added many new features to engine control, entertainment, safety systems and more. In this very harsh environment that an automobile will experience, there are stringent features that need to be a part of any electronics devices is the system.   At a minimum, any IC needs to see robust […]
