A Movement in the Making

The maker movement is made up of some 135 million adults in the U.S., however, it’s more than just a U.S. movement. Maker faires that celebrate the movement have popped up in Japan, Italy, Norway, and Chile. Makers use their skills to craft items such as clothing, baked goods, jewelry, and art; contributing $29 billion to the U.S. economy annually.

From 3D printers to laser cutters—makers employ various tools to create their goods. Many gather at makerspaces where they share these resources. Makerspaces are havens for techies, artists, and entrepreneurs. Through crowdfunding, makers are able to facilitate small-scale funding for these gathering spaces.

Toshiba TX04 for the IoT

Tosh6689A_HRES

by elektor.com:

Toshiba has added a new variant to its TX04 range of microcontrollers. The TMPM46BF10FG is targeted at IoT applications and incorporates dedicated hardware to implement a true random number generator (TRNG: SP800-90C standard) through the combination of a random entropy seed generation (ESG) circuit and Hash-DRGB created by the secure hash processor (SHA) and software program. These features offload computational overheads on the main processor and meet the standards of security required for network communications.

Based around an ARM Cortex-M4F core, with a maximum operating frequency of 120 MHz, the TMPM46BF10FG incorporates 1024 Kbyte of flash memory and 514 Kbyte SRAM required for secure communications control, four types of security circuits for network communications. The MCU also integrates an SLC NAND flash memory controller and 4- and 8-bit error correction circuitry (BCH ECC) that supports memory expansion with 1Gbit to 4Gbit SLC NAND flash memory chips.

Wago LED terminal blocks are ready for small and also big applications

obr1682_p683

Thin LED strip but also a powerful LED application sourced directly from 230V mains line are no problem for Wago series 2059, 2060 and 2061 terminal blocks.

Innovative series Wago 2060 now has two new familiar – smaller and bigger one. We talk about series 2059 and 2061. In result, WAGO 2059, 2060 a 2061 LED terminal blocks series create a comprehensive family of SMT connectors usable for practically any LED applications and in general – for every application, where advantages are low profile of connectors, reliable contact resistant to vibrations (spring clamp) and also aesthetical look…

Already the 2060 series showed us all main benefits of SMT LED connectors Wago 20xx. It has found its place on a market very quickly and it´s perspective for all new designs. Moreover, now we can choose from already three types:

  • 2059 – extra miniature connector, only 2.7 mm high. 160V/3A, for wires 0.14-0.34 mm2, 3mm pitch.
  • 2060 – universal miniature connector, only 4.5 mm high. 160V/9A, for wires 0.2-0.75 mm2, 4mm pitch. Also available with 8mm pitch version with max. operating voltage up to 630V. Also available a THR version with wave-solderable pins.
  • 2061 – the biggest (but still miniature) connector, only 5.6mm high. 320V/ 17.5A, for wires 0.5-1.,5mm2, 6 mm pitch. Ideal for direct connection of power supply to products (power input and output for LED drivers, powerful LED applications, …). A black version is also available.

All types are produced in 1-3 pole versions and also available are connecting links to interconnect two PCBs with each other (easy creation of long strings). Similarly, all types are suitable for automated pick-and-place assembly. Connector body is made of a made of an advanced material (glass fiber reinforced PPA) with a very wide range of operating temperatures.

Detailed information will provide you the Wago 2059-2060-2061 brochure.

Ohmkara Breadboarding MultiTool: Electronics Prototyping

multitool

Ohmkara is a bread-boarding ruler that helps cut, strip, and bend wires to the correct length. Ohmkara is the future of circuit design.

If you’ve done electronics prototyping, you’ve worked with a breadboard. Getting your wires or components to fit can be quite the hassle. Trying to decipher a mess like this is even more nasty. There’s no more need to buy pre-cut wires or to guesstimate while cutting jumper wires. The OHMkara tool is the one-stop protoboarding multi-tool. With your very own OHMkara multi-tool, your breadboards can look like this

DIY ESP8266 Development Board

ESP8266-development-board-power-on

ESP8266 is an 802.11 b/g/n Wi-Fi module which became very popular recently because of its capabilities and ease of use and integration. Many electronics hobbyists are building projects on ESP8266 and they generally need to connect the module to their PC or a microcontroller. Some interfacing problems arise at this point.

In this project, we are building an ESP8266 Development Board which lets the user make connection to ESP8266 from a PIC microcontroller and their PC. The board also provides all the needs to be used as microcontroller peripherals such as LCD display, pusbuttons, indicator LEDs and GPIO extension. The PC connection is done by the help of FT232RL USB-UART converter over a Mini-USB connector. Since the PIC microcontroller used is a 5V chip, 5V-3.3V bi-directional level converter circuits are also included on the board.

Buck-boost micromodules accept up to 60-V input

8056

The LTM®8055 is a 36VIN, buck-boost μModule® (micromodule) regulator. Included in the package are the switching controller, power switches, inductor and support components. A resistor to set the switching frequency, a resistor divider to set the output voltage, and input and output capacitors are all that are needed to complete the design. Other features such as input and output average current regulation may be implemented with just a few components. The LTM8055 operates over an input voltage range of 5V to 36V, and can regulate output voltages between 1.2V and 36V. The SYNC input and CLKOUT output allow easy synchronization.

The LTM8055 is housed in a compact overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8055 is RoHS compliant.

High-voltage buck regulators stay cool in tiny packages

MIC28511 TYPICAL APPLICATION_1ST PG

by Susan Nordyk @ edn.com:

A family of pin-compatible synchronous step-down switching regulators with integrated power switches, the MIC28511/12/13 from Micrel, supplies up to 4 A of output current (MIC28513) and accepts a wide input supply range of 4.6 V to 70 V (MIC28512). The devices have an operating junction temperature range of -40°C to +125°C and come in very small 24-pin, 3×4-mm FCQFN packages.

The MIC28511/12/13 regulators are offered in both Hyper Speed Control and HyperLight Load architectures, which allow for high VIN (low VOUT) operation and fast transient response, while reducing the required output capacitance and providing good light-load efficiency. They furnish an adjustable output voltage as low as 0.8 V with guaranteed accuracy to within ±1%.

8080 on a Stellaris Launchpad

This chimera is a microcontroller emulation of a UK101, an 8-bit microcomputer from the early 1980s. Needless to say I had one; it is a shocking thirty-three years since, as a spotty teenager, I soldered one together over the course of a few days. I recall the kit cost the equally shocking sum of £99.95 (a lot of pocket-money), and had to be smuggled through Irish customs in my parents’ car because the Single European Market was at that time merely a twinkle in M. Delors’ eye. In its original configuration it had 1k of user RAM, 1k of display RAM, 8k ROM Basic (from Microsoft) and a 2k ROM monitor. When it went to its present resting place in the attic a couple of years later, it had 16k of user RAM, 2k of display RAM and an additional 6k of utility ROM, all piggy-backed on the original chips.
