Step‐up DC/DC converters with built‐in inductors and control ICs

Measuring 2.5×2.0×1.0mm, the newly‐developed XCL102/XCL103 series of step‐up micro DC/DC converters is designed with built‐in inductors and control ICs. By Julien Happich @ edn-europe.com:

The use of built‐in inductors also allows PCB layouts to be simplified, minimizing unwanted radiation noise and operational trouble. The input voltage can be selected from 0.65V (operation hold voltage) to 6.0V, and the output voltage from 2.2V to 5.5V

The SparkFun Roshamglo is the new and fun way to play Rock-Paper-Scissors with your friends! The board uses the ATtiny84, and has an IR LED and receiver to communicate between badges. To play, simply point the USB connector at your opponents Roshamglo up to 5 feet away and press the 5-way switch to the left for rock, up for paper, and right for scissors. The red/green LED will display a solid red for lose, green for win, or alternate red and green for a tie. Your Roshamglo can also be worn with a lanyard clip to provide you easier access when a battle is about to ensue!

The Roshamglo Badge comes as an easy to assemble kit that only requires you to solder on six battery clips to the underside of the board and insert three AAA sized alkaline batteries. No other soldering or programming is required! Once you install the clips and batteries you can start playing Rock Paper Scissors with a friend or start hacking your Roshamglo.

The Roshamglo uses the Micronucleaus bootloader, which allows for programming from the Arduino IDE via the USB connector at the front of the board. We have included two tutorials below to help teach you how to hack your new Roshamglo as well as turn it into a remote to control to turn on and off most styles of televisions!

Snapmaker, The Modular & Multi-Functional 3D Printer

Snapmaker is a Kickstarter project with a lofty goal: to be the holy trinity for at-home makers by using detachable modules to convert between a 3D printer, a CNC carver, and a laser engraver. In retrospect, the idea seems almost obvious. All three devices need three-axis motors to work: so why not combine them into one?

But Snapmaker doesn’t just stand out for its modular nature — it’s also impressively cheap. The default Snapmaker costs $299 on Kickstarter, and includes just the 3D printer. The laser engraver and CNC modules then each cost $75, making the entire package cost $449 — which would be a pretty good price for just one of these devices, let alone all three.

Snapmaker also claims that it’s offering a fairly high-quality printer for the price, with an “all-metal” construction and 3.2-inch color touchscreen. When it comes to actual specifications, the 3D printing module can print items up to 125 x 125 x 125mm in size at a resolution of 50–300 microns. When it comes to engraving, the laser module offers a 500mW beam that can work with wood, bamboo, leather, plastic, fabric, and paper. And the CNC module can carve wood, acrylic, and PCB at speeds between 2,000 and 7,000 RPM.

Obviously, these are some pretty big promises to be making, especially at the relatively low price point that Snapmaker sells for. And as a first time, crowdfunded project from a new company that has yet to ship a product before, the burden is on Snapmaker to show that they can actually deliver. And while the company has posted videos to YouTube demonstrating the various modules in action, at the price that Snapmaker is selling, it’s possible the whole thing is too good to be true.

The crowdfunding campaign still has 35 days to go, and is already 130% funded! Check out the technical details at the official website.

ICP12 USBSTICK, A New Tool for Signals Control & Monitoring

iCircuit Technologies had produced the iCP12 usbStick, a mini size 28 pin USB PIC IO development board and a good tool for signal monitoring (as oscilloscope), data acquisition and circuit troubleshooting at 1mSec/Samples period.

The iCP12 usbStick is a PIC18F2550 based USB development board that comes preloaded with Microchip’s USB HID bootloader which allows users to upload an application firmware directly through a PC’s USB port without any external programmer. It provides access to its I/O pins through 0.1″ pitch headers. A slide switch is also provided on board to select the operation of the board in Bootloader or Normal mode.

The features of iCP12 are listed as following:

  • Mini size, easy interfacing, high performance and user friendly device
  • Used with PIC18F2553 28-Pin Flash USB PIC MCU
  • Excellent flexibility that allows user to expand the board with plug and play modules
  • Peripheral Features:
    • 13x IO Port (6x 12bit ADC pins, 2x 10 bit PWM/Freq/DAC pins)
    • Serial port emulation (UART Baud Rates: 300 bps to 115.2 kbps)
    • Supported operating systems (32bit/64bit): Windows XP ,Windows Vista, Windows 7, Windows 8, Windows 10, Linux, Mac OS X and Raspberry Pi
    • Maximum Voltage: 5Vdc
    • 100mA current output at VDD pin with over-current protection
    • 20MHz oscillator
    • Green LED – power on indicator
    • 2x LEDs (Green, Red) – status indicator
    • ICSP Connector – on-board PIC programming
    • Switch Mode Selection – Boot or Normal mode

The iCP12 usbStick board is shipped with a preloaded data acquisition firmware that emulates as a virtual COM port to PC. Thereafter, the communication between the PC and usbStick is serial. The firmware also supports basic I/O control and data logging feature. They provide a PC application named SmartDAQ that is specially developed to communicate with the usbStick and control its I/O pins, PWM outputs, and record ADC inputs.

SmartDAQ has a very friendly GUI with real-time waveform displays for 6 analog input channels. The time and voltage axes scales are adjustable. SmartDAQ can log the ADC data in both text and graphic form concurrently. One can utilize this feature to construct a low-cost data acquisition system for monitoring multiple analog sensor outputs such as temperature, accelerometer, gyroscope, magnetic field sensor, etc.

SmartDAQ v1.3 Features:

  • Sampling channel: 6x Analogs (12bits ADC/1mV Resolution) + 7x Digitals (Input/Output)
  • Maximum Sampling rate: 1KHz or 1mSec/Samples
  • Sampling voltage: 0V – 5V (scalable graph) at 5mV Resolution
  • Sampling period:

ReRAM, Process Data Where They Are Stored

Because data storage and processor are separated from each other, moving data between the storage and the computation unit became a main factor in computing.
Many techniques were developed to speed up this process, such as pipelining, caching, and look-ahead execution, but “ReRAM” appears as a new technique to solve the root of the problem by merging memory and processor together.

Resistive RAM, which known as RRAM or RERAM, is the new generation of memories. Its cells are simpler than classic transistor-based memory cells, they are non-volatile, switch fast and can run from low voltages. Researchers now have managed to make RERAM cells store more than just a ‘0’ or a ‘1’, enabling in-place computations.

The first small memory devices based on this technology is the MB85AS4MT, that was developed by Fujitsu Semiconductor with Panasonic Semiconductor Solutions. MB85AS4MT is a 4 Mbit ReRAM chip that operates with a supply voltage in the range from 1.65 to 3.6 V and has an SPI interface. One of the stand-out features of this technology is its low operating current, just 0.2 mA, at a maximum read speed of 5 MHz.

Using so-called RERAM crossbar arrays, researchers have demonstrated the in-memory execution of binary matrix computations frequently encountered in high-performance computing, algebraic cryptanalysis, combinatorics and finite geometry data, and in general large scale data analysis. Although we are only at the beginning of this technology, the results are already promising.
