Hello, today I want intoduct you to the Freescale Freedom Board with the KL25Z processor. It is a development board, builded and selled by Freescale. It features a ARM® Cortex™-M0+ , working on 48Mhz. Features: 48Mhz 128KB Flash 16KB SRAM USB OTG An accelerometer ( IC: MMA8451Q ) A capacitive tuch slider RGB LED MBED […]

Overview I developed this after my nephews got a Scalextric Sport slot car racing set for Christmas.  The set included a lap timer and counter but one thing that was missing was a way to start a race.  Having someone say “3-2-1-Go” wasn’t really doing the job, especially as it was easy to go just […]

What’s an Apple Watch good for? How about unlocking doors with just a tap on an app? We figured out how do something no one else has done for under 150 bucks, using standard door-strike hardware, our custom app, and a tiny RFduino microcontroller. In this Weekend Project we’ll show you exactly how to do […]

Description A countdown timer with super bright 7-segment displays that flash when the time is up, instead (or in addition to) an audible alarm. The design is based on a PIC16F886 microcontroller which drives the displays using a TLC5916 LED driver and dual P-channel MOSFETs. A rotary encoder with a push button is used for […]

EasyEDA is a free, zero- install, cloud-based EDA tool, designed to give electrical engineers, educators, engineering students and electronics hobbyists an Easier EDA Experience. It is easy to use circuit design, circuit simulator and PCB design that runs in your web browser. Features of EasyEDA: Cool Schematic Capture Draw schematics quickly using the available libraries on […]

If you’ve poked around the internets where electronics hobbyists collect, it is likely that you are acutely aware of our incontrovertible affinity for building timekeeping clocks.  It is similarly unlikely that you have been able to evade the plenitude of nixie tube based projects.  There is a reason for this. Nixie tubes are cool.  They […]

After testing many systems development for PIC and AVR microcontrollers, none satisfy me. So I created this system with breadboard that has satisfied me. Step 1: More space free In this development system, I put two protoboards turned 180 degrees from each other. The space that is left to just enough space to insert a […]

Researchers at Rice University’s Laboratory for Nanophotonics (LANP) have developed a new image sensor that mimics the way we see color by integrating light amplifiers and color filters directly onto the pixels. The new design enables smaller, less complex, and more organic designs for CMOS (complementary metal-oxide semiconductor) sensors and other photodetectors used in cameras. […]

The DE1-SoC board is populated with a six digit 7-segment display. All digits are connected to the FPGA. Therefore, in order to control the 7-segment display out of the Linux userspace code, one has to create a new component in QSys that is connected to the AMBA-AXI bus. But first of all, please note that […]

The latest buzz in the tech world has been about “smart” home technology. These technologies are futuristic, and make day-to-day tasks simpler, but for most of us the price for such luxuries isn’t realistic. There aren’t many cheap alternatives for the consumer; however, for the maker and DIYers there are plenty. DIY Hacks and How […]
