FUN but REAL: Manually or lying down

obr1802_uvod

Yes, these are your options when you want to set time relay of 12.51 series from Finder producer.

Italian producer accommodated less active installers that can now set, resp. program time relay also lying down. Of course, something for something – you need to have a computer but luckily it is something that almost any installer has in his pocket – a smartphone supporting NFC. So, how does it work and what needs to be done:
● Select the appropriate moment – it can be even in the middle of the night
● Choose a comfortable bed – empty one would be the best, so you don’t get distracted by anything
● Put on a comfy clothes – even dungarees, but in that case we suggest covering the bed with polythene
● For the first time, you need to be able to connect to wi-fi from the bed so you can easily download free app FINDER Toolbox from the GooglePlay.

Lay comfortably down – the most well-known and used positions are these four:

  • on the back
  • on the belly
  • on the side version L (on the left)
  • on the side version R (on the right)

In case of using a polythene, you can use all four positions also with legs on the pillow

  • The work itself is just a “game on the phone”
  • Start the game FinderToolbox. Set when and for how long you want that thing to be on and save the settings.
  • The most difficult phase of programming is about to get started. Get off the bed, come to the time relay and touch the actual time relay with your smartphone – that’s when the settings will be transferred to relay

Time relay 12.51 looks like an ordinary time relay on a DIN rail with big nice display backlight – blue signs on white background that effectively shows the necessary information.

Relay also allows programming with joystick (thus manually). This mode is for those who cannot relax while working.

Meet ESP32, New Big Brother to IoT Board ESP8266

ESP32

Alasdair Allan @ makezine.com discuss about a new IoT board released from the company that makes the ESP8266.

The ESP8266 chip, and the boards based around it, have been the new hot new thing this past year. Overnight it became — almost by stealth — one of the leading platforms for the Internet of Things. This runaway success quickly gathered a community, and it’s possible Espressif Systems may repeat that next year with their new ESP32 chip.

Prometheus: Circuit Boards in Minutes

pcb_milling

Prometheus is Not a 3D printer – it quickly carves, drills, and shapes your PCB so you don’t have to wait for a delivery truck.

Prometheus makes real circuit boards in just minutes. When we’re prototyping, we need a tool that can give us nearly instant feedback – not feedback that comes in a few week’s time in the form of a PCB delivery. Let the PCB manufacturers make the hundreds or thousands of boards for your production run – not your prototypes. If production is your goal, Prometheus will help get you there faster.

LT8331 – Low IQ Boost/SEPIC/ Flyback/Inverting Converter

8331

Linear Technology Corporation announces the LT8331, a current mode step-up DC/DC converter with an internal 500mA, 140V switch. It operates from an input voltage range of 4.5V to 100V, making it suitable for use with a wide range of input sources found in industrial, transportation and avionic applications. The LT8331 can be configured as either a boost, SEPIC, flyback or inverting converter. Its switching frequency is programmable from 100kHz to 500kHz, enabling designers to minimize external component sizes.  Burst Mode® operation reduces quiescent current to only 6µA while keeping output ripple below 20mVP-P. The combination of a high voltage MSOP-16E package and tiny externals ensures a very compact footprint while minimizing solution cost.

Supercapacitors to replace batteries?

Microsoft PowerPoint - ????1

by Martin Cooke @ elektormagazine.com:

It was reported last year that researchers at Rice University in the US, led by chemist James Tour had developed a method of producing a form of graphene on commercial polyimide plastic sheet by zapping it with a laser. The process is called LIG (Laser Induced Graphene). The resulting graphene layer is not a conventional flat sheet made up of hexagonally-organized atoms but instead a spongy array of graphene flakes attached to the polyamide, giving a greatly increased surface area. This property can be exploited to build supercapacitors.

NerO – An Energy Efficient Arduino UNO Compatible Design

NerO

A reference design for an Arduino UNO compatible board based on the FTDI FT231X USB UART, delivers 5V at a full 1A without overheating.

The UNO R3 is the staple of most Arduino based projects but it’s been around for a number of years and many of the features have been improved for example by Adafruit and Sparkfun who make excellent enhanced UNO compatibles. However, our additional requirements for a full 1A current without excess heat dissipation and FCC/CE conformity led us to consider a new 3rd party UNO compatible reference design that met these requirements hence the inspiration behind NerO
