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.

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

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.

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.

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%.

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.

by elektor.com:

Tektronix Inc., has introduced a new entry-level Arbitrary/Function Generator. The AFG1022 is targeted at educational institutions and supports a wide range of use cases and course subjects. The AFG1022 also integrates with the new TekSmartLab wireless lab instrument management solution.

Michael Ewald, General Manager, Bench Products, Tektronix stated that “Tektronix strongly believes that a rich hands-on experience dramatically improves education outcomes, that’s why we are working hard to meet the needs of colleges and universities including good price-performance on instrumentation, integrated courseware and ease of administration.”
Key performance specifications include dual-channel, 25 MHz bandwidth with 1 mVpp to 10 Vpp output, 14-bit vertical resolution and 1 µHz frequency resolution. It provides a 125 MS/s sample rate along with 64 MB of built-in non-volatile memory and USB memory expansion for user-defined waveforms.

On the functionality side, the instrument offers 50 built-in standard functions and arbitrary waveforms with continuous, modulation, sweep and burst modes to cover almost all the test requirements found in basic education labs. A built-in 200 MHz counter with 6-digit resolution offers an easy and precise way of performing frequency, period, pulse width, and duty cycle measurements.

LTC2966

The LTC®2966 is a low current, high voltage dual channel voltage monitor. Internal high value resistors sense the input monitor pins providing a compact and low power solution for voltage monitoring. Each channel includes two comparator reference inputs (INH/INL) to allow configuration of a high and low threshold using an external resistive divider biased from the on-chip reference. Range selection pins are provided for each channel to set the internal resistive dividers for 5x, 10x, 20x and 40x scaling. The thresholds are scaled according to the range selection settings. Additionally, either INH or INL can be grounded to enable built-in hysteresis. Polarity selection pins allow each output to be inverted. The outputs are 100V capable and include a 500k pull-up resistor to an internal supply.

Gas sensing techniques are continually being investigated to improve selectivity and sensitivity of identifying different types of gases. There are resistive gas sensors, quartz crystal microbalance, direct thermoelectric, electrochemical cell and other exotic types such as MEMS-tunable Fabry-Perot filter spectral sensors with lead-selenide detector and pulsed broadband infrared emitter light source. The ams sensor is a resistive type.

The resistive sensor design relies upon heating circuitry for temperature control of the entire system. There are different types of resistive gas sensor techniques and construction. Some are based upon metal-oxide (MOX) thin films which are small in size, low-cost, and low power as well as able to use low-power integrated analog front ends.
