Lowest-drift bandgap voltage reference reaches 1.5ppm/°C, offers low dropout

Posted on 20 October, 2015 by mixos

by Graham Prophet @ edn-europe.com:

LT6657 is a family of ultra-stable bandgap voltage references that exhibits less than 1.5ppm/°C of temperature drift. Reinforcing this performance, the device has only 0.5ppm p-p of low frequency noise, less than 30 ppm of long term drift and 35 ppm of thermal hysteresis.

The LT6657 is fully specified for –40°C to 125°C and was designed for the most demanding high performance instrumentation, test equipment and automotive systems. The LT6657’s buffered output can source and sink up to 10 mA. The LT6657 can operate on a supply voltage from as low as 50 mV above the output, up to 40V, and with a supply current of only 1.2 mA. In shutdown mode, power consumption is reduced to 4 µA. Load regulation error is less than 6 ppm/mA and line regulation error is less than 4 ppm/V, both under worst case conditions.

UP – Intel x5-Z8300 board in a Raspberry Pi2 form factor

UP, the credit card computer board for makers powered by Intel Quad Core Atom X5-8300 1.84GHz, running Linux, Windows 10, and Android

We haven’t seen anything like that on the market. We saw plenty of cost effective boards, often powered by RISC technology, and industrial solutions with a wide range of standard form factors, performance and technology but with high prices and poor or absent community support. We tried to merge the best of the two worlds, makers and industrial market. Maybe we were asking for too much. Or maybe not. We put the best x86 low power consumption and high performance technology available today in the market into a credit card size board and created a community to support it.
The answer is UP.

UP is a credit card size board which merges the benefits of Raspberry Pi2, the standard “de facto” of makers with the high performance and low power consumption of latest tablet technology : the Intel Cherry Trail Atom Quad Core x5-Z8300 64 bits up to 1.84GHz ( http://ark.intel.com/products/87383/Intel-Atom-x5-Z8300-Processor-2M-Cache-up-to-1_84-GHz ). Thanks to the 14nm technology, the CPU is rated at only 2W SDP.

How to make wearable display – OLED SSD1306 display run by ATtiny85

Step by step tutorial, with no steps to skip.

The main goal of this tutorial is to show how to make wearable display run by Attiny85 and OLED display SDD1306.

Due to running campaign for ATtiny25/45/85 PCB TINY CHEAP VERSATILE Arduino compatible on Indiegogo I did prototype of wearable display base on natural leather, to show what is possible with ATtiny25/45/85 PCB.

How to test a power supply or solar system?

Posted on 19 October, 2015 by mixos

Electronic loads, programmable and with a recovery function are the best choice for dynamic testing simulating real conditions.

Usually you don´t test your power supply and you assume it is working well with your equipment. But what if not? Sometimes your equipment fails without any evident reason and it might be because your power supply is not sufficient for your application. We have a solution which helps you identify the problems with the power supple – electronic load.
With electronic load you can test your power supply or solar system and you can easily program the behavior of your device or even a bigger load. Elektro Automatik offers a wide range of electronic loads, even with energy recovering function.Further information can be found in the electronic loads catalogue (14,5 MB). Upon request, we´re able to provide you with any product from the Electro Automatik catalogue (14,5 MB).

Simple FM Radio

Posted on 19 October, 2015 by mixos

by electronics-diy.com:

This is one of my favorite radio builds just because of how simple it is and how well it is able to pick up a lot of FM radio stations. I have browsed the world in search of a one transistor FM receiver. I have seen a couple but they were always attached to some sort of added device, such as another IC or another transistor for amplification in the receiver itself. Through my continued quest of searching for that too good to be true one transistor, I happened to run across a super-regenerative receiver, by Charles Kitchin, famous for his vast knowledge of regenerative designs. I printed out the schematic and made it. It turned out extremely well.

Tiny Message Board

by tareker @ instructables.com:

We will make a tiny connected message board with a 0.96″ OLED display that can be controlled from your phone. We will use the IFTTT “DO” app to set and clear the reminder so that no extra hardware will be required besides the OLED display. In addition to the reminder, our tiny message board can display 3 other lines, which we will use to display the daily weather temperature forecast and a surf report, which will be pushed via a couple of IFTTT recipes.

Arduino Display for Liquid Flow Sensors

This project was done for a Friend Of a Friend. He needs to monitor water flow rate and quantity for his solar heating projects. He is mainly interested in this two inch sensor but also sent along a small plastic hose bib type similar to the Adafruit 828. Both of these sensors are turbine types, water flow spins a plastic wheel which magnetically triggers a pulse output proportional to the speed at which the wheel is turning. There’s lots of these sensors made for irrigation and industrial processes.

The Pendulum Clock

Posted on 19 October, 201519 October, 2015 by mixos

by Dylan Rush :

If you’ve ever rode the Link Light Rail in Seattle to the airport, you may have glanced out of the window while traveling through a tunnel and seen playing cards illuminated on the walls. These images are not made from two dimensional screens. Each display is just a row of lights that changes rapidly as the train drives by, giving the illusion of a two-dimensional picture.

The University Street station also has rows of lights blinking on the walls on the mezzanine floor. I always point out the artwork whenever I walk through the station with someone. At first glance the displays just appear to be red lines, but if you move your eyes rapidly from side to side, there are images hidden in how the lights blink.

Today during Opening Conference at Maker Faire Rome, Josh Walden Senior Vice President of Intel Corporation and Massimo Banzi, co-founder of Arduino, announced the upcoming release of Arduino 101 (U.S.) and Genuino 101 (outside the U.S.). The board features a 32-bit Intel® Quark™ microcontroller for minimal power consumption, 384 kB of flash memory, 80 kB of SRAM (24kB available for sketches), an integrated DSP sensor hub, Bluetooth* Low Energy radio, and 6-axis combo sensor with accelerometer and gyroscope.

We collaborated with Intel to provide the maker community an affordable learning and development board ideal for entry-level makers and education environments and also the first widely available development board based on the tiny, low-power Intel Curie module.
