SureCore, the UK-based embedded memory process developer, has announced that it has taped out its low power SRAM IP demonstrator chip in STMicroelectronics’ 28nm Fully Depleted Silicon-on-Insulator (FD-SOI) process. The device will be used to validate the benefits of the start-up’s patented array control and sensing scheme, which is claimed to lowers active power consumption […]

Keyboard, display, sensor or other device can be connected by means of Bluetooth modules even without cables. Many times, it´s more practical to have devices interconnected wirelessly. Whether we need a simpler transfer of values from some sensor or a more complicated data communication between two devices, Bluetooth modules will manage it without a long […]

In our portfolio can be found quality knobs from company Cliff suitable for a wide range of potentiometers and encoders.   A device with excellent specification, quality components used, …., but a one step is still missing to reach a great overall impression – it is to use a quality and aesthetic control components. Probably […]

A possibility to read an RFID card even on a longer distance is usually highly appreciated at its everyday usage.   As we know, RFID module range is expressively depending on a size and shape of the RFID antenna (coil). That´s why the module with a big antenna has a potentially bigger chance to reach […]

Today I want to present you one of my larger craft projects. This time it is not just about software, but also about the associated hardware. What is it? A web radio! I like to listen to internet radio stations, but I didn’t want to run my pc only for listening to webradios.  Connecting my […]

„Power bank“ or a mobile power supply with a USB output can contribute also to your undisturbed work. Nowadays already almost every battery-operated device with a USB port has a possibility to be operated or recharged through this port. Whether it is a smartphone, external harddrive, various modems, dataloggers and many other specialized devices, almost […]

Housed in a low-profile 24-pin QFN package, the LTC4040 from Linear Technology is a 2.5-A lithium-battery–backup power-management system for 3.5-V to 5-V supply rails that must be kept active during a main power failure. The device uses an on-chip bidirectional synchronous converter to provide high-efficiency battery charging, as well as high-current, high-efficiency backup power. When […]

Single microcontroller based 12v to 230v inverter with intelligent battery charging (Made by me) Here I describe the circuit as: *single microcontroller/controller (ATMEGA16/32) *no op-amps, only chips are the micro, opto-couplers and regulator (7805) *low-battery/overload/short-circuit protection *thyristor controlled battery charger, using the MOSFET body diode as the AC-DC rectifier *charger maintains the battery voltage (top) […]

The Oscilloscope Watch The Oscilloscope Watch has all the features of a modern watch (time, calendar, alarm, etc…) combined with all the features of the popular Xprotolab (Oscilloscope, Waveform Generator, Logic Analyzer, Protocol Sniffer, Frequency Counter). The Xprotolab has been featured in several other online magazines, such as Hack a Day. and Elektor. Here are […]

Description The DS28E80 is a user-programmable nonvolatile memory chip. In contrast to the floating-gate storage cells, the DS28E80 employs a storage cell technology that is resistant to gamma radiation. The DS28E80 has 248 bytes of user memory that are organized in blocks of 8 bytes. Individual blocks can be write-protected. Each memory block can be […]
