(Phys.org)—Recent announcements on the Raspberry Pi site had two items on the topic of cameras, with the November 23 announcement of a camera board demo of the upcoming Raspberry Pi camera module and on November 22 with announcements of who won the Foundation’s summer coding contest. The Raspberry Pi is a credit-card sized computer board that plugs into a TV and a keyboard, also described as a miniature ARM-based PC.

Overview Where I live most of the time, the AC power drops out upon occasion. This used to leave me groping around in the dark for a flashlight. I could have bought a battery-backed up “emergency light” for about US$35, but being basically metal boxes with floodlights attached, they would make my living room look […]

ATmega32 for which we will see its datasheet is The high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 32KB of programmable flash memory, 2KB SRAM, 1KB EEPROM, an 8-channel 10-bit A/D converter, and a JTAG interface for on-chip debugging. The device supports throughput of 16 MIPS at 16 MHz and operates between 4.5-5.5 volts. Click to Download […]

ATmega8 is an atmel’s low-power 8-bit AVR RISC-based microcontroller combines 8KB of programmable flash memory, 1KB of SRAM, 512K EEPROM, and a 6 or 8 channel 10-bit A/D converter. The device supports throughput of 16 MIPS at 16 MHz and operates between 2.7-5.5 volts. To find out its complete Specs, here is the link to ATmega8 datasheet , […]

Multifunctional gas soldering tool will help you at many various applications like: soldering, melting, hot-cutting, welding and woodburning (pyrography)… This quality gas soldering tool provides a freedom of usage for example outdoor and everywhere where no electricity is available. But DREMEL 2000 VersaTip isn´t only a gas soldering tool with adjustable temperature

our friend  Vassilis decided to build his own manual Pick & Place machine to facilitate his work with 0402 SMD and other fine pitch parts: If you are dealing with tiny SMD parts (e.g. 0402 resistors and capacitors), a manual pick and place machine is a helpful piece of equipment for prototyping and small-batch manufacturing

Integrated Wireless Power Li-Ion Charger Receiver, Qi (WPC) Compliant  Texas Instruments has launched a pair of ICs designed to simplify wireless power solutions for mobile devices, consisting of a single-chip wireless power receiver with integrated battery charger and a ‘free-position’ transmitter that enlarges the charging area by a factor of four. The bq51050B is the industry’s wireless power receiver compatible with the Wireless Power Consortium (WPC) 1.1 Qi standard.

[MAXIM APP 5509] This document details the Oceanside (MAXREFDES9#) subsystem reference design, a 3.3V to 15V input, ±15V (±12V) output, isolated power supply. The Oceanside design includes a high-efficiency step-up controller, a 36V H-bridge transformer driver for isolated supplies, a wide input range, and adjustable output low-dropout linear regulator (LDO)

The MAX6070/MAX6071 offer a very low noise and low-drift voltage reference in a small 6-pin SOT23 package. These devices provide a 1/f noise voltage of only 4.8µVP-P at an output voltage of 2.5V, with a temperature drift of 6ppm/°C (max)

SKL14 can be used in switch-mode power supplies or as protection diodes and thanks their really miniature dimensions, they are also suitable at the lack of PCB space.  SMT Technologies enable a substantial increase of current density thanks to a very good heat transfer from a component to a PCB. Almost a zero length of „leads“ of SMT components also features another positive aspects like a significant suppression of a parasitic inductancy and a possibility to construct circuits with a high components density and a minimal PCB tracks length, what significantly decreases an undesired radiation (EMI) for example in switch-mode power supplies
