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 […]

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
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
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
Polyswitch-es provide a big service at protection of devices, where they behave like „resettable“ fuses. How many times it is suitable or necessary to use a fuse in a device, but a relatively bulky fuse socket simply doesn´t have a space in our device (or it would spoil a device design) and we also don´t
Polyswitch fuses miniSMD series will protect not only Read More »
A breadboard can be also made at home, from one side, it will be more expensive than those on the markets, but for another side, it’s possible to add commonly used elements, like LEDs, switches, or other things, for example I added a precision IC socket that makes putting in and out of ICs much
Solder stencils are pretty cheap these days, but for a single, quick production run of a really simple design, it seems like a waste of resources to have a professional one produced and shipped to the lab. Of course, if you have a laser cutter handy, you can make a pretty nice one, but if all you’ve got is
