How to turn and ordinary external harddrive into a datalocker using only a PIC microcontroller, a keypad and some various other components. Step 1: Parts The parts you need: – 3.5″ SATA harddrive enclosure – 2.5″ SATA harddrive NOTE: This will not work with a 3.5″ IDE enclosure and a 2.5″ IDE drive without a […]

description Add general purpose input/output lines to your computer based projects. This circuit is a 12 pin digital GPIO interface using the Microchip PIC18f14k50 microcontroller which connects to an USB host port. The microcontroller is available in through-hole DIP20 and SMD packages, too. Circuit diagram The device is powered by the USB bus. 12 port […]

Using adaptive current-limit PFM (pulse frequency modulation) control, the ISL9120 switching regulator from Intersil realizes efficiencies of up to 98%, while automatically transitioning between buck and boost modes without significant output disturbance. The part accommodates a wide input voltage range of 1.8 V to 5.5 V and has an adjustable output voltage range of 1 […]

Wireless technology IQRF was introduced to you in our recent article „IQRF – a wireless technology which breaks barriers“ and in our SOS webinar „How to integrate wireless technologies into your devices without a long-term programming?”. In the time of publishing of the previous article, was the IQRF Alliance launch in a status of intensive […]

First of all, if you have any questions, feel free to comment! I’d be more than happy to answer your question as good as possible!! Materials used : – PIC 18F452 Microcontroller ( any PIC microcontroller with enough pins will do ) – 7 Segment common anode LED display – 24 Mhz Crystal – A […]

With Eltechs ExaGear Desktop you can run Intel x86 application on your ARM-based Mini PC simultaneously with common native applications. ExaGear is a virtual machine that implements virtual x86 Linux container on ARM and allows you to run Intel x86 applications directly on ARM. It is like QEMU but 5 times faster! You can even run Windows […]

At this week’s IEDM 2014, held in San Francisco, California, nanoelectronics research center imec demonstrated an ultra-low power RFID transponder chip. Operating at sub 1V voltage and realized in thin-film transistor technology (TFTs) on plastic film, the chip paves the way for universal sensing applications, such as item level RFID tagging, body area networks (BAN) […]

jump to a section:supplies about LED arrays design construction customizing/programming washing and wearing troubleshooting and FAQ **NOTE** As of Fall 2007, skip the ugly microcontroller programming (don’t buy the STK500 or the AVR chip)… Get a LilyPad Arduino instead. It’s much easier to sew and to program! See my LilyPad Arduino tutorial for help on […]

An eight pin Microchip PIC microcontroller is programmed to operate from a 32768 Hz watch crystal and output waveforms which, when displayed on an oscilloscope, show the time in HH:MM:SS format. The screen capture shows winscope showing 12:46: … Step 1: Design the character set On an oscilloscope screen, vertical axis (up and down) corresponds […]
