In a bid to encourage greater use of TI’s Programmable Real-time Unit (PRU) built into the Sitara AM335x and AM437x family of devices which power the BeagleBone Black development board Texas have announced the PRU cape. The PRU is made up of dual 200 MHz coprocessors, implementing a low-latency subsystem optimized for deterministic, real-time processing allowing […]

About this project It fixes a problem you probably didn’t even know you had – unlocking the full potential of your graphics card hardware. By simulating the presence of an attached display, Headless Ghost allows you to use all of the power and available resolutions locked away inside your graphics hardware, which might otherwise be

Description This is not an ordinary project, but an attempt to make a PCB that is suitable for TDA2050 and LM1875 and has all the necessary circuitry on board – power supply, speaker protection, delayed turn-on and fast turn-off. This is achieved using the convenient uPC1237 IC. TDA2050 and LM1875 are pin to pin compatible,

Description RGB LED disco light is a simple project designed around PIC16F72 microcontroller. This firmware is a RGB driver, as name suggests it is used to derive or light red, green and blue LEDs in particular fashion. Its main feature is the pattern shown on LEDs. It is quite difficult to describe pattern in words

I’m working on a project that requires full orientation information, so I built an Inertial Measurement Unit from scratch. I really like the 9DOF IMU board that Sparkfun makes – the calibration code that comes with it is fantastic – but I wanted to redesign the board so that it could be made at a

UPDATE: I added an alarm function to both versions of the clock. UPDATE: I updated the code so that setting the clock does not affect the seconds accuracy – no resyncing of seconds required. UPDATE: I removed the personal messages from the clock code for the “Pusheen” version in the download links Video at:: http://youtu.be/ikNw1iLE9vg

Despite a low power consumption this relay handles 5A/250VAC while maintaining a considerably long lifetime. If we should mark an electronic component by a term “sympathic”, then the FTR-MY MY relay should be one of adepts …. Why? It´s simply chic. FTR-MY is: ● slim (5mm), so it doesn´t take much time on a PCB
Slim, humble and long-age – this is the Fujitsu FTR-MY relay Read More »
Home This project is to build a portable GPS geared towards runners (well, me and what I think a runner wants a GPS thingy for). It’s sponsored by the University of Minnesota’s ECE Envision Fund. The hardware is basically complete, and the software is functional, if not polished. This is what the main screen looks like
